## v0.3 Architecture (Mastery Scoring + Competency Rubrics + VC)
|
||||
|
||||
> **Status:** Released (v0.1.5, merged to main). Research-refined (v0.3 RESEARCH stage).
|
||||
> **Decisions:** D-031 (operator tier, overrides D-007 for operator surface), D-032 (mastery gate), D-033 (W3C VC 2.0), D-034 (k-anonymity), D-035 (IRT 1PL), D-036 (scenario library), D-037 (path structure), D-038..D-049 (clarify).
|
||||
> **v0.4 note:** The operator-tier sections below (auth, cohort aggregation, Postgres) were anticipatory in v0.3 and are now confirmed/refined in the v0.4 section (§ v0.4 Operator-Tier Architecture). The v0.3 mastery/VC/IRT sections are released and unchanged.
|
||||
|
||||
### Hybrid Storage Topology (D-031 — confirmed in v0.4)
|
||||
|
||||
Learner-local state stays in SQLite (D-007 preserved); operator-tier state goes to a new Postgres service. The two stores never share a session and never join via cross-DB FKs (`learner_ref` is an opaque string in Postgres).
|
||||

### v0.3 Component Map (mastery + VC + IRT — released, unchanged)
|

```
|

Pipecat server (Python)
|

├─ ... (v0.2 voice loop unchanged) ...

├─ Rubric engine (server/mastery/)
|
||||
│ ├─ rubric_loader.py (rubrics/<skill>.yaml → Pydantic)

### Mastery Scoring Flow (off the voice path)
|
||||
|
||||
```
|
||||
Session end (server/session_recorder.py)
|
||||
│
|
||||
├─ 1. Evidence extraction (LLM, async, off-voice-path)
|
||||
│ deepseek-v4-flash:cloud, temp=0
|
||||
│ Input: session turns + scenario.rubric_criteria
|
||||
│ Output (JSON-schema-validated): [{criterion_id, quote, signals: [...]}]
|
||||
│ Guard: fuzzy-match quote vs transcript → reject+re-extract on mismatch (R-MAST-02)
|
||||
│
|
||||
├─ 2. Rule-based scoring (deterministic, no LLM — REQ-NFR-MAST-01)
|
||||
│ rubric_scorer.py: signals → 1-5 level per criterion
|
||||
│
|
||||
├─ 3. Mastery Score (deterministic)
|
||||
│ scenario_score = weighted_mean(levels, weights)
|
||||
│ scenario_pass = scenario_score ≥ 3.0 AND every criterion ≥ 2 (conjunctive floor)
|
||||
│ path MasteryScore = mean(scenario_scores for passing scenarios only)
|
||||
│ path gate open = ≥3 distinct scenarios passed AND MasteryScore ≥ 3.5 (D-032)
|
||||
│
|
||||
├─ 4. IRT θ update (deterministic, <100ms — REQ-NFR-IRT-01)
|
||||
│ θ ← θ + (outcome − P) × σ²/(σ² + 1); persist to SQLite learner_ability (D-046)
|

|
||||
nightly reconciliation reconciles 7-day windows
|
||||
```
|
||||
|
||||
### VC Issuance + Verification Flow
|
||||
|
||||
```
|
||||
Mastery gate opens (week-final)
|
||||
├─ issuer.py: build payload {scenariosPassed, rubricScore, completedWeeks:6, evidence, validUntil:+3y}
|
||||
│ canonicalize (JCS) → sign Ed25519 → store in Postgres issued_credentials
|
||||
└─ Verification (third party): GET /vc/verify/<id> → fetch pubkey from verificationMethod URL
|
||||
→ validate Ed25519 sig → check Status List → return {valid, status, issuer, mastery, verifiedAt}
|
||||
```
|
||||
|
||||
### Postgres Schema (operator tier — D-040)
|
||||
|
||||
Tables: `operators` (id, username, password_hash argon2id), `issued_credentials` (id, learner_ref opaque-string, vc_payload_json, signature_b64, status, issued_at), `mastery_gate_events` (id, learner_ref, path, week, scenarios_passed_json, rubric_scores_json, gate_opened_at — REQ-NFR-MAST-02 audit), `cohort_aggregates` (path, week, window_start/end, metric, value, cell_suppressed — k-anon via write-time suppression, weekly partitions), `issuer_keys` (id, public_key Multikey, private_key_enc, status active|superseded). `gen_random_uuid()` in PG16 (no extension). No cross-DB FKs.
|
||||
|
||||
### CT Resource Sizing (v0.3 bump)
|
||||
|
||||
| Resource | v0.2 | v0.3 | Rationale |
|
||||
|----------|------|------|-----------|
|
||||
| Memory | 4096 MB | **6144 MB** | Postgres ~1GB + praxis ~2GB + build headroom (R-MT-01) |
|
||||
| Rootfs | 16 GB | 16 GB | Postgres data on named volume, not rootfs |
|
||||
| CPU | 2 | 2-4 | Postgres + praxis concurrent; 2 floor, 4 preferred |
|
||||
|
||||
### v0.3 Risks (from RESEARCH.md)
|
||||
|
||||
Top risks for PLAN: R-MAST-01 (N=3 thin for credential → label formative), R-AUTH-01 (Secure cookie + no-TLS pilot), R-MT-01 (Postgres resource contention), R-VC-01 (custom VC code ~200 LOC), R-MAST-02 (LLM hallucinated quotes → fuzzy-match guard), R-IRT-01 (cold-start θ → fall back to scenario.difficulty until ≥5 sessions). Full table in RESEARCH.md.
|
||||
|
||||
> **v0.4 note:** R-AUTH-01 is resolved in v0.4 via config-driven `PRAXIS_COOKIE_SECURE` (see § v0.4 Operator-Tier Architecture). R-MT-01 is confirmed + mitigated (6GB CT, 03:00 CT nightly jobs).

## v0.4 Operator-Tier Architecture (Cohort Dashboard + Auth + Postgres)
|
||||
|
||||
> **Status:** Research-refined (v0.4 RESEARCH stage). Informed by `.ciagent/RESEARCH-v0.4-operator-tier.md`.
|
||||
> **Decisions:** D-040 (Postgres 2nd service), D-050 (asyncpg pool + service DNS), D-051 (VC key migration), D-052 (operator bootstrap), D-053 (3 dashboard views), D-054 (async hook + nightly job), D-055 (pg_dump backup), D-056 (signed stateless cookies), D-057 (server-side auth enforcement).
|
||||
> **v0.3 audit:** 2 anticipatory assumptions overturned (asyncpg min_size 2→1, weekly partitions→plain table), 1 refined (Secure cookie → config-driven). See RESEARCH-v0.4 § v0.3 Assumption Audit.

**Connection DSN (D-050):** `postgresql://praxis:${PRAXIS_PG_PASSWORD}@postgres:5432/praxis` (host = service name on praxis-net).
|
||||
|
||||
### asyncpg Pool (D-050)
|
||||
|
||||
```python
|
||||
# Shape only — lifespan context manager
|
||||
from contextlib import asynccontextmanager
|
||||
import asyncpg
|
||||
|
||||
@asynccontextmanager
|
||||
async def lifespan(app):
|
||||
app.state.pg_pool = await asyncpg.create_pool(
|
||||
dsn=os.environ["PRAXIS_PG_DSN"],
|
||||
min_size=1, # D-050 (lower than v0.3 anticipatory min_size=2)
|
||||
max_size=10,
|
||||
command_timeout=10,
|
||||
)
|
||||
try:
|
||||
yield
|
||||
finally:
|
||||
await app.state.pg_pool.close()
|
||||
|
||||
app = FastAPI(lifespan=lifespan)
|
||||
```
|
||||
|
||||
The `PraxisStore` (aiosqlite) keeps its current per-call connect pattern — **pools are independent and must not be shared** (different backends, different lifecycles).
|
||||
|
||||
### Auth Middleware Flow (D-056, D-057)
|
||||
|
||||
```
|
||||
Client request → /api/operator/cohort
|
||||
│
|
||||
├─ Starlette SessionMiddleware
|
||||
│ ├─ reads praxis_op cookie
|
||||
│ ├─ validates HMAC-SHA256 signature (itsdangerous)
|
||||
│ ├─ checks max_age (8h expiry)
|
||||
│ └─ populates request.session = {operator_id, issued_at} (or empty if invalid)
|
||||
│
|
||||
├─ current_operator Depends (router-level)
|
||||
│ ├─ reads request.session["operator_id"]
|
||||
│ ├─ if missing → 401 "not authenticated"
|
||||
│ ├─ fetches operator from Postgres operators table
|
||||
│ ├─ if not found / not is_active → 401 + clear cookie
|
||||
│ └─ returns Operator (injected into route)
|
||||
│
|
||||
└─ Route handler (GET /api/operator/cohort)
|
||||
└─ queries Postgres cohort_aggregates (k-anonymized) → returns JSON
|
||||
```
|
||||
|
||||
**Login flow:**
|
||||
```
|
||||
POST /api/operator/login {username, password}
|
||||
│
|
||||
├─ slowapi rate-limit check (5/min per IP — D-041)
|
||||
│ └─ if exceeded → 429 + Retry-After
|
||||
│
|
||||
├─ fetch operator by username from Postgres
|
||||
├─ argon2-cffi PasswordHasher().verify(stored_hash, password)
|
||||
│ ├─ if invalid → 401 (increment rate-limit counter)
|
||||
│ └─ if valid → check_needs_rehash(stored_hash) → rehash if params bumped
|
||||
│
|
||||
└─ Set signed cookie: request.session["operator_id"] = op.id
|
||||
→ response 200 {operator: {id, username, display_name}}
|
||||
```
|
||||
|
||||
**React route guard (UX only — server is authority per D-057):**
|
||||
```
|
||||
/operator/dashboard mount
|
||||
│
|
||||
├─ GET /api/operator/me (with cookie)
|
||||
│ ├─ 200 → render dashboard
|
||||
│ └─ 401 → redirect to /operator/login
|
||||
```
|
||||
|
||||
### Aggregation Pipeline (D-045, D-053, D-054)
|
||||
|
||||
```
|
||||
Session end (server/session_recorder.py)
|
||||
│
|
||||
├─ 1. Mastery flow (asyncio.Task — existing v0.3 pattern)
|
||||
│ └─ evidence → rubric score → IRT θ → gate check → VC issuance
|
||||
│
|
||||
└─ 2. Cohort aggregation hook (asyncio.Task — v0.4, chained after mastery)
|
||||
├─ reads session outcome + rubric scores + scenario failure_mode
|
||||
├─ computes k-anonymized aggregate for (path, metric, window_start)
|
||||
├─ COUNT(DISTINCT learner_ref) >= 10 check
|
||||
│ ├─ if ≥10 → upsert value to cohort_aggregates
|
||||
│ └─ if <10 → upsert with cell_suppressed=TRUE, value=NULL
|
||||
└─ failures log + nightly job reconciles (idempotent)
|
||||
|
||||
Nightly reconciliation (in-process asyncio scheduler, 03:00 CT)
|
||||
├─ recomputes all 7-day windows for all paths
|
||||
├─ idempotent upsert by (path, metric, window_start)
|
||||
└─ guarantees REQ-NFR-DASH-02 (freshness ≤ 24h)
|
||||
```
|
||||
|
||||
### 3 Dashboard Views (D-053)

### Postgres Schema (operator tier — D-040, refined by D-050..D-053)
|
||||
|
||||
Tables: `operators` (id UUID DEFAULT gen_random_uuid(), username TEXT UNIQUE, password_hash TEXT argon2id, display_name TEXT, role TEXT DEFAULT 'operator', is_active BOOLEAN DEFAULT TRUE, created_at TIMESTAMPTZ, last_login_at TIMESTAMPTZ), `issued_credentials` (id UUID, operator_id UUID REFERENCES operators, learner_ref TEXT opaque, vc_type TEXT, payload_jsonb JSONB, issued_at TIMESTAMPTZ, revoked_at TIMESTAMPTZ), `mastery_gate_events` (id UUID, learner_ref TEXT, scenario_id TEXT, path_id TEXT, gate_outcome TEXT, recorded_at TIMESTAMPTZ, source TEXT DEFAULT 'sync'), `cohort_aggregates` (path TEXT, metric TEXT, window_start DATE, window_end DATE, value NUMERIC, cell_count INTEGER, cell_suppressed BOOLEAN, updated_at TIMESTAMPTZ, PRIMARY KEY (path, metric, window_start) — **plain table, not partitioned** (v0.4 scale; add partitioning post-pilot)), `issuer_keys` (id TEXT, public_key TEXT, private_key_enc BYTEA, status TEXT active|superseded, created_at TIMESTAMPTZ). `gen_random_uuid()` in PG16 core (no extension). No cross-DB FKs.
|
||||
|
||||
### VC Key Migration (D-042, D-051)
|
||||
|
||||
```
|
||||
v0.4 first boot:
|
||||
│
|
||||
├─ 1. Postgres issuer_keys table created (pg_migrate.py)
|
||||
│
|
||||
├─ 2. Read v0.3 active public key from SQLite issuer_keys
|
||||
│ └─ insert into Postgres issuer_keys with status='superseded'
|
||||
│ (private key NOT migrated — only public key archived for verification)
|
||||
│
|
||||
├─ 3. Generate fresh Ed25519 keypair in Postgres issuer_keys (status='active')
|
||||
│ └─ private key encrypted at rest via nacl.SecretBox (PRAXIS_VC_ISSUER_KEY root key)
|
||||
│
|
||||
└─ 4. Verification endpoint (server/vc/verification.py):
|
||||
├─ extract key_id from proof.verificationMethod
|
||||
├─ get_public_key_for_verification(store, key_id)
|
||||
│ └─ queries by id (not status) → finds active OR superseded keys
|
||||
└─ verify_proof(secured_doc, verify_key)
|
||||
├─ v0.3 VCs → v0.3 key_id → archived (superseded) public key → verifies ✓
|
||||
└─ v0.4 VCs → v0.4 key_id → active public key → verifies ✓
|
||||
```
|
||||
|
||||
**IssuerKeyStore protocol:** the existing `server/vc/issuer_keys.py` functions take a `PraxisStore` (SQLite). v0.4 refactors to an `IssuerKeyStore` protocol/ABC with methods `init_issuer_key`, `get_active_signing_key_row`, `get_public_key_row`, `set_issuer_key_superseded`. Both `PraxisStore` (SQLite, for v0.3 compat) and `PgStore` (Postgres, for v0.4) implement it.
|
||||
|
||||
### Backup Strategy (D-055)
|
||||
|
||||
```
|
||||
Host-side cron (decoupled from praxis service uptime):
|
||||
03:30 CT nightly:
|
||||
docker compose exec -T postgres pg_dump -U praxis -Fc praxis \
|
||||
-f /backups/praxis-$(date +%u).dump
|
||||
→ pgbackups named volume, %u = day-of-week 1-7 → rolling 7-file retention
|
||||
|
||||
Restore drill:
|
||||
docker compose exec postgres pg_restore -U praxis -d praxis \
|
||||
--clean --if-exists /backups/praxis_3.dump
|
||||
(never restore into live DB without stopping praxis first)
|
||||
```
|
||||
|
||||
### CT Resource Sizing (v0.4 bump)
|
||||
|
||||
| Resource | v0.2 | v0.3 (anticipatory) | v0.4 (confirmed) | Rationale |
|
||||
|----------|------|---------------------|------------------|-----------|
|
||||
| Memory | 4096 MB | 6144 MB | **6144 MB** | Postgres ~400MB + praxis ~500MB + Docker ~200MB + build headroom ~1GB + margin |
|
||||
| Rootfs | 16 GB | 16 GB | **16 GB** | Postgres data on pgdata named volume, not rootfs; pgbackups on named volume |
|
||||
| CPU | 2 | 2-4 | **2-4** | Postgres + praxis concurrent; 2 floor, 4 preferred |
|
||||
|
||||
### v0.4 Risks (from RESEARCH-v0.4-operator-tier.md)
|
||||
|
||||
Top risks for PLAN: R-AUTH-01 (Secure cookie + no-TLS → config-driven flag, grill must sign off), R-VC-MIG-01 (VC key migration loses v0.3 public key → archive as superseded before activating new key), R-DASH-03 (SPA fallback breaks voice UI → catch-all route before StaticFiles mount), R-MT-01 (Postgres resource contention → 03:00 CT nightly jobs, 6GB CT). Full table (20 risks) in RESEARCH-v0.4-operator-tier.md.
|
||||
|
||||
### v0.4 New Dependencies
|
||||
|
||||
**Pip (pyproject.toml):** `asyncpg>=0.29` (Postgres driver), `argon2-cffi>=23.1` (password hashing), `slowapi>=0.1` (rate limiting). `pynacl`, `canonicaljson`, `base58` already present (v0.3).
|
||||
|
||||
**Npm (client/package.json):** `react-router-dom@^7` (React routing for /operator/*). No chart library — inline SVG sparklines (zero deps).

## 1. Audit Summary
|
||||
|
||||
| | |
|
||||
|---|---|
|
||||
| **Verdict** | **HEALTHY (with warnings)** |
|
||||
| **Confidence** | 0.88 |
|
||||
| **Critical issues** | 0 (0 blocking; 4 doc-drift fixes applied in working tree — not committed) |
|
||||
| **Warnings** | 5 (3 cosmetic stale-status — FIXED in working tree; 2 branch-topology notes — non-blocking) |
|
||||
| **Reconstruction test** | PASS — project state fully reconstructable from git log alone |
|
||||
| **Ship-ready** | YES (subject to orchestrator's milestone-ship decision; P2 review + audit = this report; milestone merge to main + v0.2 release pending) |
|
||||
| # | Check | Result | Notes |
|
||||
|---|-------|--------|-------|
|
||||
| 1 | Reconstruction test | ✅ PASS | git log `v0.1.3..v0.1.4` (P1) + `v0.1.2..v0.1.3` (P0) match `.ciagent/` checkpoint progression; 13/13 REQ-IDs implemented; ROADMAP v0.3 phases correct |
|
||||
| 2 | `.ciagent/` file discipline | ⚠️ WARN → PASS (after fix) | Canonical names present; 2 stale-header fixes applied (REQUIREMENTS.md duplicate v0.2 header, PERSONAS.md post-grill roster drift); config.json milestone = v0.3 ✅ |
|
||||
| 3 | Branch hygiene | ⚠️ WARN | `phase/01-mastery-core` + `milestone/v0.3-mastery-scoring` + `phase/02-final-review-ship` exist; `phase/01-mastery-core` was NOT merged via squash (see §3.2 — fast-forward, no merge commit); stale v0.2 phase branches noted (not deleted) |
|
||||
| 4 | Commit discipline | ✅ PASS | All v0.3 P1 commits have `---ci---` with `project:praxis`, `phase:1`, `milestone:v0.3`; P0 commits have `phase:0`; conventional-commit format followed (feat/docs) |
|
||||
| 5 | Tag discipline | ✅ PASS | v0.1.0..v0.1.4 strictly increasing, no skips; v0.1.3 = P0 ship, v0.1.4 = P1 ship; both annotated tags |
|
||||
|
||||
**One-line summary:** The Praxis v0.2 Proxmox LXC deployment milestone is internally consistent, fully reconstructable from git history, free of committed secrets, and behaviorally verified (77 pytest + 121 bats pass, e2e smoke passes, Docker image builds, all 13 shell scripts syntax-valid). The git log `---ci---` blocks, `.ciagent/` files, CHECKPOINT.json, branch topology, and tags all agree on phase/milestone state. Four documentation-drift fixes were applied to the working tree (REQUIREMENTS.md REQ-DEPLOY statuses `pending`→`complete`, ROADMAP.md phase markers, PROJECT.md status header, config.json `status: specify`→`phase-1-complete`) — these are non-blocking corrections that should be committed by the orchestrator at P2 completion. Two branch-topology warnings (remote `phase/02-final-review-ship` lags local; v0.1 `phase/01-minimal-voice-loop` exists only on remote) are non-blocking.
|
||||
**Final verdict: HEALTHY** (with 2 auto-fixed doc-drift items + 1 branch-hygiene warning for non-squash merge)
|
||||
|

|
||||
|
||||
## 2. Reconstruction Test — ✅ PASS
|
||||
## 2. Check 1 — Reconstruction Test
|
||||
|
||||
**Goal:** Can the full project state be reconstructed from git history alone?
|
||||
### 2.1 P1 commits (`v0.1.3..v0.1.4`)
|
||||
|
||||
**Method:** Parsed all `---ci---` blocks from `git log --all`; reconstructed phase/stage/decisions/escalations/requirements; compared against `.ciagent/` file contents.
|
||||
|
||||
**Findings:**
|
||||
|
||||
| Source | Reconstructable? | Evidence |
|
||||
|---|---|---|
|
||||
| Current phase | ✅ | Latest v0.2 commit `3262bfd` → `phase: 1, status: complete`; CHECKPOINT.json `phase: 1, stage: complete, next_phase: 2`; phase/02 branch reset to milestone tip (audit is first P2 action — no P2 commits yet, expected) |
|
||||
| Milestone | ✅ | All 14 v0.2 commits on `milestone/v0.2-lxc-deploy` carry `milestone: v0.2` |
|
||||
| Phases shipped | ✅ | Phase 0: commits `70994e1`→`98779b5` (specify→clarify→research→plan→grill→complete), tagged `v0.1.0`, Gitea release #371; Phase 1: commits `f04b9b3`→`3262bfd` (execute 4 slice commits → verify → merge → ship), tagged `v0.1.1`, Gitea release #374 |
|
||||
| Decisions | ✅ | D-027..D-030 in clarify commit `9d54fbe`; D-031..D-038 implied in research/plan commits `658bbc3`/`0df1ec3`; G-101..G-113 in grill commit `2999c51` — all match PROJECT.md / GRILL.md / PLAN.md / RESEARCH.md |
|
||||
| Grill binding decisions | ✅ | G-101..G-106 (2 MUST + 4 FIX) in grill commit `2999c51` + GRILL.md §v0.2; all 6 addressed in EXECUTE commits (G-101 in `bb17615`+`93d33ec`, G-102 in `f04b9b3`, G-103 in `d32e4d4`/`93d33ec`, G-104 in `bb17615`, G-105 in `f04b9b3`, G-106 in `93d33ec`) — matches VERIFY.md §3-4 |
|
||||
| Requirements | ✅ | 20 v0.2 REQ-IDs (16 REQ-DEPLOY + 4 REQ-NFR-DEPLOY) listed as `covered` in verify commit `6cf63cb` (18/20 covered, 2 deferred live-E2E) — matches REQUIREMENTS.md §Deployment + VERIFY.md §6 REQ coverage matrix |
|
||||
| Escalations | ✅ | 0 escalations in v0.2. Both phases shipped with `release: status: created` (no release-pending escalation — Gitea repo exists for v0.2; contrast with v0.1 which had 2 release-pending escalations). CHECKPOINT.json `release_status: created` matches. |
|
||||
| CHECKPOINT consistency | ✅ | `CHECKPOINT.json` = `{phase: 1, stage: complete, milestone: v0.2, release_status: created, tag: v0.1.1, next_phase: 2}` — matches latest ship commit `3262bfd` (`phase: 1, status: complete, release.status: created, release.url: .../tag/v0.1.1`) |
|
||||
| Tags | ✅ | `v0.1.0` annotated tag → `615721a` (phase 0 merge commit); `v0.1.1` annotated tag → `8974d90` (phase 1 merge commit). Both present locally + on remote. Tag annotations: `v0.1.0 — praxis v0.2 phase 0 (pre-execution)`, `v0.1.1 — praxis v0.2 phase 1 (LXC deploy implementation)`. |
|
||||
|
||||
**Reconstruction verdict: PASS.** The project state is fully reconstructable from the 47 `---ci---` blocks. The single commit without a `---ci---` block (`bcb0118 chore: seed .gitignore for env secrets`) is the initial seed — explicitly exempted per the audit workflow.
|
||||
|
||||
---
|
||||
|
||||
## 3. File Discipline — ✅ PASS (after fixes)
|
||||
|
||||
**Expected `.ciagent/` files (13 tracked + 1 gitignored):**
|
||||
|
||||
| File | Present? | Valid? | Notes |
|
||||
|---|---|---|---|
|
||||
| `config.json` | ✅ | ✅ (after fix) | Valid JSON; required fields present. **FIXED:** `projects[0].status` was `specify` (stale from SPECIFY stage) → updated to `phase-1-complete` to reflect actual state. |
|
||||
| `PROJECT.md` | ✅ | ✅ (after fix) | Required sections present (Vision, Objective, v0.2 Scope, Product Principles, Requirements, Constraints, Key Decisions D-001..D-038, Target Users, Success Metrics). **FIXED:** `Status:` header was `in-progress` → updated to `phase 1 complete — P2 review/ship in-progress`. |
|
||||
| `ARCHITECTURE.md` | ✅ | ✅ | v0.1 topology + v0.2 deployment section (Docker-in-LXC, image build, secrets, sizing) appended in research commit `658bbc3`; matches actual `server/`, `client/`, `db/`, `scripts/proxmox/` code structure |
|
||||
| `ROADMAP.md` | ✅ | ✅ (after fix) | 2 v0.2 phases documented + Final Phase (P2). **FIXED:** Phase 0 + Phase 1 markers were `in-progress`/`pending` → updated to `complete (tagged v0.1.0/v0.1.1)`; P2 marker updated to `in-progress`. |
|
||||
| `REQUIREMENTS.md` | ✅ | ✅ (after fix) | 20 v0.2 REQ-IDs (16 REQ-DEPLOY + 4 REQ-NFR-DEPLOY) + 15 v0.1 REQ-IDs (retained for reference). **FIXED:** All 16 REQ-DEPLOY statuses were `pending` → updated to `complete`; REQ-NFR-DEPLOY-01/02/04 → `complete`; REQ-NFR-DEPLOY-03 → `deferred (live cluster required)`. Status header `in-progress` → `phase 1 complete`. |
|
||||
| `RESEARCH.md` | ✅ | ✅ | 648 lines; 10 research questions (Docker-in-LXC, CT sizing, FastAPI StaticFiles, multi-stage build, systemd, health-check timeout); 6 risks R-DEPLOY-01..06; D-013..D-020 (v0.1) + v0.2 findings |
|
||||
| `PERSONAS.md` | ✅ | ✅ | 5 active personas for v0.2 (lead-developer, backend-engineer, data-engineer, devops-engineer, frontend-engineer DEACTIVATED); matches PLAN.md persona load distribution |
|
||||
| `PLAN.md` | ✅ | ✅ | 999 lines; 10 slices / 4 waves / 34 tasks / 20 REQ-IDs covered; persona assignments; wave dependency graph; exit criteria; MH-01..MH-28 must-haves |
|
||||
| `GRILL.md` | ✅ | ✅ | Concatenated file: v0.1 grill (G-001..G-008, 28 challenges, PROCEED @ 0.72) + v0.2 grill (G-101..G-113, 15 challenges, APPROVE_WITH_NOTES @ 0.85). v0.2 section appended in grill commit `2999c51`. All 6 v0.2 binding fixes (G-101..G-106) addressed in EXECUTE. |
|
||||
| `REVIEW.md` | ⚠️ STALE | ⚠️ | **v0.1 P2 review** — header says "Milestone: v0.1 (foundation)", references `milestone/v0.1-praxis`, D-001..D-020. This is a carry-over artifact from the v0.1 milestone's P2 phase. It was NOT updated for v0.2. **Non-blocking** — v0.2's P2 review has not yet been written (this audit is the first P2 action). The orchestrator should write the v0.2 REVIEW.md during P2. |
|
||||
| `VERIFY.md` | ✅ | ✅ | v0.2 Phase 1 verification report — 4 layers (Structural/Behavioral/Security/Quality); 121 bats + 77 pytest pass; 4 P0 fixes; 8 P1+ noted; 18/20 REQ covered, 2 deferred; 25/28 must-haves pass. Updated in verify commit `6cf63cb` + merge `8974d90`. |
|
||||
| `CHECKPOINT.json` | ✅ | ✅ | Valid JSON; `phase: 1, stage: complete, milestone: v0.2, release_status: created, tag: v0.1.1, next_phase: 2` — consistent with latest ship commit `3262bfd`. |
|
||||
| `.env.secrets` (untracked) | ✅ | ✅ | Permissions `0600`; gitignored (`git check-ignore` matches); NOT committed (`git ls-files` absent). Contains `GITEA_TOKEN` — not inspected for audit (out of scope; correctly excluded from VCS). |
|
||||
|
||||
**Stale-file check:** `REVIEW.md` is a stale v0.1 artifact (see table). All other `.ciagent/` files are correctly scoped to v0.2 or are retained-for-reference v0.1 content (REQUIREMENTS.md v0.1 REQs, GRILL.md v0.1 section).
|
||||
|
||||
**Secrets handling:**
|
||||
|
||||
| Check | Result |
|
||||
|---|---|
|
||||
| `.ciagent/.env.secrets` exists | ✅ |
|
||||
| Permissions `0600` | ✅ (`stat -c "%a"` → `600`) |
|
||||
| Gitignored | ✅ (`git check-ignore .ciagent/.env.secrets` → matches; `.gitignore` covers `.env`, `.env.secrets`, `.env.*`) |
|
||||
| NOT committed | ✅ (`git ls-files .ciagent/` lists 13 files — `.env.secrets` absent) |
|
||||
| No secret values in tracked files | ✅ (pickaxe `-S'94a866bd...'` across all history → 0 matches in committed content; grep for `sk-[a-zA-Z0-9]{20,}` / `_API_KEY="[^"]{15,}"` → 0 hardcoded values; all script refs use `${VAR}` expansion or empty defaults) |
|
||||
| `.env.example` has no real secrets | ✅ (all values empty or commented out) |
|
||||
| `.dockerignore` excludes `.ciagent/` | ✅ (secrets never in build context) |
|
||||
| Remote URL contains embedded token | ⚠️ — see W-4 below (git config, not project file) |
|
||||
|
||||
**File discipline verdict: PASS (after 4 working-tree fixes to config.json, PROJECT.md, ROADMAP.md, REQUIREMENTS.md).**
|
||||
|
||||
---
|
||||
|
||||
## 4. Branch Hygiene — ✅ PASS (with warnings)
|
||||
|
||||
**Expected v0.2 branches (3) + v0.1 reference branches (carried over):**
|
||||
|
||||
| Branch | Exists (local)? | Exists (remote)? | State |
|
||||
|---|---|---|---|
|
||||
| `main` | ✅ | ✅ | 3 commits (seed + v0.1 milestone complete + v0.1 release created). v0.2 milestone NOT merged to main yet — correct, orchestrator ships after P2. |
|
||||
| `milestone/v0.2-lxc-deploy` | ✅ | ✅ | 17 commits; contains all 119 project files including `scripts/proxmox/`, `Dockerfile`, `docker-compose.yml`; tags `v0.1.0` (→ `615721a`) + `v0.1.1` (→ `8974d90`) point here. Local = remote = `3262bfd`. |
|
||||
| `phase/00-pre-execution` | ✅ | ✅ | 6 commits (specify→clarify→research→plan→grill + ship); merged to milestone via `615721a` (squash-merge content). Local = remote = `2999c51`. |
|
||||
| `phase/01-lxc-deploy` | ✅ | ✅ | 7 commits (4 execute slices + verify + merge + ship); merged to milestone via `8974d90`. Local = remote = `6cf63cb`. |
|
||||
| `phase/02-final-review-ship` | ✅ | ✅ (stale) | **Local = `3262bfd`** (reset to v0.2 milestone tip — correct, this audit is first P2 action); **remote = `1baf8b9`** (v0.1 P2 tip — stale, not yet force-pushed). See W-1. |
|
||||
| `milestone/v0.1-praxis` | ✅ | ✅ | v0.1 milestone (reference); 6 commits; tags `v0.0.0`/`v0.0.1`/`v0.0.2` point here. Local = remote = `766637c`. |
|
||||
| `phase/01-minimal-voice-loop` | ❌ (local) | ✅ (remote) | v0.1 phase 1 branch — exists only on remote (`fe29bf0`), not pruned locally. See W-2. |
|
||||
|
||||
**Merge topology:**
|
||||
- `git log milestone/v0.2-lxc-deploy --not main` → 14 commits (all v0.2 work). Phase branches squash-merged: `615721a` (phase 0) + `8974d90` (phase 1, merge commit with 2 parents `98779b5`+`6cf63cb`). Squash-merge is valid — detailed per-task history preserved on phase branches; milestone carries consolidated "phase complete" commits.
|
||||
- `main` has only v0.1 content — v0.2 milestone NOT merged to main yet. **Correct**: orchestrator runs milestone ship after P2 review + audit complete.
|
||||
|
||||
**HEAD not on main:** ✅ (HEAD = `phase/02-final-review-ship` @ `3262bfd`)
|
||||
|
||||
**Tags:**
|
||||
|
||||
| Tag | Type | Target | Annotation | Present remote? |
|
||||
|---|---|---|---|---|
|
||||
| `v0.1.0` | annotated | `615721a` (phase 0 merge) | `v0.1.0 — praxis v0.2 phase 0 (pre-execution)` | ✅ |
|
||||
| `v0.1.1` | annotated | `8974d90` (phase 1 merge) | `v0.1.1 — praxis v0.2 phase 1 (LXC deploy implementation)` | ✅ |
|
||||
| `v0.0.0` | annotated | `48cbd4a` (v0.1 P0) | `v0.0.0: phase 0 — pre-execution` | ✅ (v0.1 reference) |
|
||||
| `v0.0.1` | annotated | `b77536a` (v0.1 P1) | `v0.0.1: phase 1 — minimal viable voice loop` | ✅ (v0.1 reference) |
|
||||
| `v0.0.2` | annotated | `fbd6602` (v0.1 milestone) | `v0.0.2: phase 2 (final) — review + audit + milestone ship` | ✅ (v0.1 reference) |
|
||||
|
||||
**Branch hygiene verdict: PASS.** All v0.2 branches exist + pushed (except phase/02 remote is stale — W-1). Tags v0.1.0 + v0.1.1 correct + pushed.

## 5. Commit Discipline — ✅ PASS
|
||||
|
||||
**Commit inventory (48 total across all branches; 14 on v0.2 milestone not on main):**
|
||||
|
||||
| Prefix | Count (v0.2) | Valid? |
|
||||
|---|---|---|
|
||||
| `docs(...)` | 7 | ✅ (init, clarify, research, plan, grill, 2× ship) |
|
||||
| `feat(P01)` | 4 | ✅ (slice-scoped: SLICE-01+02, 03+04, 05+06+07, 08+09+10) |
|
||||
| `feat(milestone)` | 1 | ✅ (phase 1 merge) |
|
||||
| `docs(P01)` | 1 | ✅ (verify) |
|
||||
| `docs(P00)` | 4 | ✅ (clarify, research, plan — wait, clarify is `docs(P00)`) |
|
||||
| `docs(grill)` | 1 | ✅ |
|
||||
| `chore` | 1 (seed, exempted) | ⚠️ exempted per audit spec |
|
||||
|
||||
**`---ci---` block coverage:** 47 / 48 commits (98%). The 1 commit without is `bcb0118 chore: seed .gitignore for env secrets` — the initial seed, explicitly exempted. **All 47 CI-generated commits have `---ci---` blocks.** ✅
|
||||
|
||||
**Phase/milestone/status in `---ci---` blocks (v0.2 commits):**
|
||||
|
||||
| Field | Values observed | Consistent? |
|
||||
|---|---|---|
|
||||
| `phase:` | `0` (7 commits), `1` (7 commits) | ✅ matches ROADMAP phases |
|
||||
| `milestone:` | `v0.2` (all 14) | ✅ matches config.json + all .ciagent files |
|
||||
| `status:` | specify, clarify, research, plan, grill, complete (×2 ship), execute (×4), verify, complete (merge) | ✅ matches pipeline stages |
|
||||
| `release:` | `status: created` (×2 ship commits) + URLs | ✅ matches CHECKPOINT.json + Gitea releases #371/#374 |
|
||||
|
||||
**Commit message convention:** All commits use `prefix(scope): description` with valid prefixes (`docs`, `feat`, `chore`). Slice-scoped feature commits use `feat(P01): SLICE-NN+NN+NN — ...` format consistently. ✅
|
||||
|
||||
**Secret scan:**
|
||||
|
||||
| Scan | Result |
|
||||
|---|---|
|
||||
| `git ls-files` for env/secret/key/.db/credential/token filenames | 0 secret files (`.env.example` + `tests/test_pending_keys.py` are the only matches — neither contains secrets) |
|
||||
| Full-history pickaxe `-S'94a866bd1a4964ab4859bcc440155e30cf5bf8de'` | 0 matches in committed content (token only in `.ciagent/.env.secrets` which is untracked) |
|
||||
| Grep for `sk-[a-zA-Z0-9]{20,}` and `_API_KEY="[^"]{15,}"` in working tree | 0 hardcoded key values found |
|
||||
| Grep for `GITEA_TOKEN\|API_KEY\|SECRET\|PASSWORD` in scripts/compose/Dockerfile | All refs use `${VAR}` expansion, empty defaults (`:-`), or are test fixtures (`gitea-test-token`, `abc`) — no real secret values |
|
||||
| `stage-snippet.sh` G-101 fix | ✅ Token baked via `sed` at staging time from env var — not committed to repo |
|
||||
|
||||
**Commit discipline verdict: PASS.** No secrets committed. Convention followed. All CI commits have `---ci---` blocks.
|
||||
|

|
||||
|
||||
## 6. REQ-ID Consistency — ✅ PASS (after fix)
|
||||
|
||||
**20 v0.2 REQ-IDs from REQUIREMENTS.md → code + test coverage:**
|
||||
|
||||
### Functional (REQ-DEPLOY-01..16)

|
||||
|
||||
### Non-Functional (REQ-NFR-DEPLOY-01..04)
|
||||
|
||||
| REQ-ID | Priority | Code path | Tests | Status (after fix) |
|
||||
|---|---|---|---|---|
|
||||
| REQ-NFR-DEPLOY-01 | must | `lxc-deploy.sh` idempotency (ct_exists + running + health → skip; --recreate/--reconfigure) | `lxc-deploy.bats` (16 idempotency tests) | complete |

|
||||
|
||||
**Coverage: 19/20 REQ-IDs COVERED, 1 DEFERRED** (REQ-NFR-DEPLOY-03 live first-boot timing — requires Proxmox cluster). REQ-DEPLOY-15 is complete (121 bats tests pass) though 3 PLAN-specified test files are missing (timing.bats, idempotency.bats, docker-build.bats — coverage adequate via other files per VERIFY.md P1-02).

|
||||
|

**REQ-ID consistency verdict: PASS (after REQUIREMENTS.md status fix).** All 20 REQ-IDs have code paths + test coverage (19 complete, 1 deferred). No orphaned requirements. VERIFY.md §6 coverage matrix matches.
|
||||
- `9263229` — phase 0 ship commit (no `---ci---` block — ship/tag commits are exempt per v0.2 precedent; they record release metadata, not phase state)
|

**7 functional REQ-IDs listed** (NFRs not listed in P0 block — added in P1 implementation block). ✅ Consistent with P0 = planning-only (no implementation).
|

### 2.3 Active REQ-IDs — 13 implemented
|

Per PLAN.md §REQ-ID Coverage Matrix + VERIFY.md + P1 merge commit:

|
||||
|
||||
**13/13 REQ-IDs covered. 0 partial. 0 deferred within v0.3.** Test files verified present at tag `v0.1.4`: 15 test files matching the mastery/VC/IRT/path/rubric/scenario surface.
|
||||
|
||||
**Deferred to v0.4 (8 REQ-IDs — operator tier, per grill Axis 2):** REQ-DASH-01, REQ-AUTH-01, REQ-MT-01, REQ-MT-02, REQ-NFR-DASH-01, REQ-NFR-DASH-02, REQ-NFR-AUTH-01, REQ-NFR-MT-01.
|
||||
|
||||
> **Note:** REQUIREMENTS.md:44 lists REQ-DASH-01 as `active | P1` in the "Employer / Program Dashboard (v0.3)" section, while the "Out of Scope" section at REQUIREMENTS.md:82 marks it `deferred to v0.4`. This is a **pre-grill artifact** — the dashboard REQ table was not updated when the grill's Axis 2 verdict deferred the operator tier. The §"Auth & Multi-Tenancy (deferred to v0.4)" section correctly defers REQ-AUTH-01/MT-01/MT-02. The 13-REQ-ID count is correct (DASH-01 is *not* counted in the 13 per PLAN.md:454). The DASH-01 row in the active table is **stale doc drift** — see §7 auto-fix.
|
||||
|
||||
### 2.4 ROADMAP.md v0.3 phases
|
||||
|
||||
- Line 3: `**Milestone:** v0.3 (Mastery scoring + competency rubrics + verifiable credentials)` ✅
|
||||
- Phase 0 — Pre-Execution (line 14): ship target `v0.1.3`, status in-progress (should be `complete` post-v0.1.3 — minor stale-status, non-blocking; ROADMAP is a planning doc, not a live status tracker)
|
||||
- Phase 1 — Mastery Core + VC Issuance (line 31): ship target `v0.1.4`, status `planned` (should be `complete` post-v0.1.4 — same minor stale-status)
|
||||
- Final Phase P2 (line 39): ship target `v0.1.5`, status `planned` ✅
|
||||
- v0.4 milestone (line 47): operator tier deferred from v0.3 ✅
|
||||
- v0.2 milestone (line 51): marked complete ✅
|
||||
- Previous milestone line (line 5): `v0.2 — complete, tagged v0.1.2, release #377` ✅
|
||||
|
||||
**Result: ✅ PASS** — ROADMAP reflects v0.3 phases correctly; 2 phase-status lines are stale (`in-progress`/`planned` should be `complete`) but this is cosmetic — the checkpoint + tags are the source of truth for phase status.

| # | Severity | Location | Finding | Impact | Action |
|
||||
|---|---|---|---|---|---|
|
||||
| W-1 | Nit | `origin/phase/02-final-review-ship` | Remote branch tip `1baf8b9` is the **v0.1 P2** tip; local branch reset to `3262bfd` (v0.2 milestone tip). Remote not yet force-pushed with v0.2 reset. | Non-blocking. Local branch is correct for P2 work. Remote will update when orchestrator pushes P2 commits. | Orchestrator pushes phase/02 at P2 completion. |
|

| W-2 | Nit | `phase/01-minimal-voice-loop` | v0.1 phase 1 branch exists only on remote (`origin/phase/01-minimal-voice-loop` @ `fe29bf0`), not pruned/created locally. | Non-blocking. Branch is v0.1 reference; not needed for v0.2 P2. | Optional: `git fetch --prune` or create local tracking branch if v0.1 history needs local access. |
|
||||
| W-3 | Nit | `.ciagent/REVIEW.md` | Contains v0.1 P2 review (header: "Milestone: v0.1", references `milestone/v0.1-praxis`, D-001..D-020). NOT updated for v0.2. | Non-blocking. v0.2 P2 review has not been written yet (this audit is first P2 action). The v0.1 review is retained as reference. | Orchestrator writes v0.2 REVIEW.md during P2 (overwrite or append v0.2 section). |
|
||||
| W-4 | Nit | `.git/config` (remote URL) | `remote.origin.url` contains embedded Gitea token: `https://coreci:94a866bd...@git.cloudinit.dev/...`. This is git config, NOT a project file — not committed, not in `.ciagent/`. | Non-blocking for audit (not a committed secret). However, storing tokens in remote URLs is a mild security hygiene issue — anyone with read access to `.git/config` sees the token. | Optional: switch to credential helper or SSH remote. Not an audit blocker (out of scope — git config, not project artifact). |
|
||||
| W-5 | Nit | `scripts/proxmox/e2e-deploy.sh:80` (carry-over from VERIFY P1-06) | `curl -sS --insecure ${PROXMOX_TLS_SKIP_VERIFY:+--insecure}` — the first `--insecure` is unconditional, so TLS verification is always skipped regardless of `PROXMOX_TLS_SKIP_VERIFY`. | Non-blocking (pilot deployment with self-signed PVE certs). Flagged in VERIFY.md P1-06 but not fixed. | Optional: remove unconditional `--insecure`, keep only the conditional one. |
|
||||
### 4.1 Required v0.3 branches
|
||||
|
||||
```
|
||||
milestone/v0.3-mastery-scoring ✅ exists
|
||||
phase/01-mastery-core ✅ exists
|
||||
* phase/02-final-review-ship ✅ exists (current)
|
||||
```
|
||||
|
||||
### 4.2 phase/01 merge to milestone/v0.3
|
||||
|
||||
**⚠️ WARN — non-squash merge.** The phase/01 → milestone/v0.3 integration was a **fast-forward**, not a squash merge:
|
||||
|
||||
- `4d39596` (P1 merge commit) has **single parent** `9263229` (confirmed via `git show 4d39596 --format='parents: %P'`)
|
||||
- `phase/01-mastery-core` tip = `bb6fe6e` (verify commit) — this is 6 commits ahead of the pre-phase base
|
||||
- `milestone/v0.3-mastery-scoring` tip = `a3c25f6` (phase 1 ship commit, child of `4d39596`)
|
||||
- The merge commit `4d39596` brought in the phase/01 work as a linear fast-forward (single parent, no second parent from phase/01 branch)
|
||||
|
||||
This means **all 6 phase/01 implementation commits are directly on the milestone branch's history** (not squashed into one). The v0.2 precedent used true squash merges (`8974d90 feat(milestone): merge phase/01 lxc-deploy` was a merge commit with 2 parents).
|
||||
|
||||
**Impact:** Non-blocking — the commits are all conventional-commit formatted with `---ci---` blocks, so reconstruction still works. But it violates the "squash merge to milestone" pattern from v0.2. **Recommendation for P2 ship:** when merging phase/02 → milestone/v0.3 → main, use `--squash` or a true merge commit to preserve the phase-boundary integrity.
|
||||
|
||||
### 4.3 Stale v0.2 phase branches
|
||||
|
||||
```
|
||||
phase/01-lxc-deploy stale (v0.2 — noted, NOT deleted)
|
||||
phase/02-final-review-ship stale (v0.2 — noted, NOT deleted)
|
||||
```
|
||||
|
||||
**Note:** `phase/02-final-review-ship` is shared between v0.2 and v0.3 — it was reset from v0.2's `3262bfd` tip to v0.3's `a3c25f6` tip for this P2 phase. This is the v0.2 precedent (ROADMAP.md:80 notes the same branch name reuse). The current pointer is v0.3-correct (== `milestone/v0.3-mastery-scoring` tip).
|
||||
|
||||
`phase/01-lxc-deploy` is a v0.2 stale branch — **noted, not deleted** per audit instructions.
|
||||
|
||||
### 4.4 Result
|
||||
|
||||
**⚠️ WARN.** All required v0.3 branches exist; phase/01 was fast-forward merged (not squash — deviation from v0.2 pattern, non-blocking); stale v0.2 branches noted.

### 5.1 P1 commits — `---ci---` block verification
|
||||
|
||||
**All 5 audit checks PASS (2 after working-tree fixes).**
|
||||
All 6 phase/01 implementation commits + 1 merge commit have `---ci---` blocks with `project:praxis`, `phase:1`, `milestone:v0.3`:

|
||||
| Commit | `---ci---` fields | ✅ |
|
||||

|
||||
|
||||
| Commit | `---ci---` fields | ✅ |
|
||||
|--------|-------------------|---|
|
||||
| `dc673e5` phase 0 merge | `project:praxis, phase:0, milestone:v0.3, status:complete` | ✅ |
|
||||
| `bea2af1` v0.2 complete | `project:praxis, phase:2, milestone:v0.2, status:complete, milestone_complete:true` | ✅ (v0.2 carry-over) |
|
||||
|
||||
### 5.3 Conventional-commit format
|
||||
|
||||
All v0.3 commits use conventional commits:
|
||||
- `feat(milestone):` / `feat(P01):` — implementation + merge commits ✅
|
||||
- `docs(milestone):` / `docs(ship):` / `docs(grill):` / `docs(P00):` / `docs(P01):` — planning + ship + verify commits ✅
|
||||
- No `decision()` commits observed in v0.3 (decisions recorded in PROJECT.md decision table, not as standalone commits — consistent with v0.2 precedent)
|
||||
|
||||
**Result: ✅ PASS** — all v0.3 commits have well-formed `---ci---` blocks with correct phase/milestone; conventional-commit format followed.

## Overall Audit Verdict
|
||||
## 6. Check 5 — Tag Discipline
|
||||
|
||||
# **HEALTHY (with warnings)**
|
||||
### 6.1 Tag sequence
|
||||
|
||||
The Praxis v0.2 Proxmox LXC deployment milestone is:
|
||||
- **Fully reconstructable** from git history (47 `---ci---` blocks across 5 v0.2 branches + 2 tags)
|
||||
- **Internally consistent** (git log ↔ `.ciagent/` files ↔ CHECKPOINT.json ↔ ROADMAP phases all agree — after 4 stale-status fixes)
|
||||
- **Secret-clean** (no secrets committed; `.env.secrets` correctly excluded; G-101 token-baking fix verified)
|
||||
- **Behaviorally verified** (73 pytest pass, 121 bats pass, e2e smoke passes, Docker image builds, 13 shell scripts syntax-valid — reproduces VERIFY.md exactly)
|
||||
- **Requirement-complete** (19/20 v0.2 REQ-IDs covered, 1 deferred live-E2E, 0 orphaned)
|
||||
- **Escalation-correct** (0 escalations in v0.2; both phases shipped with `release: created` — Gitea releases #371 + #374)
|
||||
```
|
||||
v0.1.0 acac807 v0.2 phase 0 (pre-execution)
|
||||
v0.1.1 db82fcd v0.2 phase 1 (lxc-deploy implementation)
|
||||
v0.1.2 0889850 v0.2 final (milestone release)
|
||||
v0.1.3 dc673e5 v0.3 phase 0 (pre-execution — planning)
|
||||
v0.1.4 4d39596 v0.3 phase 1 (mastery core + VC issuance)
|
||||
```
|
||||
|
||||
5 warnings (3 cosmetic stale-status — FIXED in working tree; 2 branch-topology notes — non-blocking). **0 critical issues.** The milestone is ready for the orchestrator to ship (P2 review → milestone merge to main → v0.2 release).
|
||||
- All 5 tags exist, strictly increasing (v0.1.0 → v0.1.4), no skips ✅
|
||||
- All tags are **annotated** (confirmed via `git tag -l` + tagger metadata) ✅
|
||||
- v0.1.3 = P0 ship ✅ (points to `dc673e5` phase 0 merge commit)
|
||||
- v0.1.4 = P1 ship ✅ (points to `4d39596` phase 1 merge commit)
|
||||
- No skipped tags in the v0.1.* sequence ✅
|
||||
|
||||
### 6.2 Tag-to-branch residency
|
||||
|
||||
- v0.1.3 is on `milestone/v0.3-mastery-scoring` and `phase/02-final-review-ship` ✅
|
||||
- v0.1.4 is on `milestone/v0.3-mastery-scoring` and `phase/02-final-review-ship` ✅
|
||||
- Neither tag is on `main` yet (correct — P2 milestone merge to main pending) ✅
|
||||
|
||||
**Result: ✅ PASS** — tag discipline clean.

||||

*End of v0.2 milestone P2 audit report. AUDIT only — SHIP is the orchestrator's next step.*
|
||||
## 7. Auto-Fixes Applied
|
||||
|
||||
This audit applied 2 doc-drift fixes to `.ciagent/` files (no code files modified):
|
||||
|
||||
### Fix 1 — REQUIREMENTS.md stale v0.2 duplicate header
|
||||
|
||||
REQUIREMENTS.md had a **duplicate header block** from v0.2 at lines 1-6 (above the v0.3 header at lines 8-13):
|
||||
```
|
||||
# Praxis — Requirements
|
||||
|
||||
**Milestone:** v0.2 (Proxmox LXC deployment)
|
||||
**Status:** phase 1 complete — P2 review/ship in-progress (18/20 REQ covered, 2 deferred)
|
||||
...
|
||||
# Praxis — Requirements
|
||||
|
||||
**Milestone:** v0.3 (Mastery scoring + competency rubrics)
|
||||
```
|
||||
|
||||
**Fix:** Removed the stale v0.2 header block (lines 1-7). The v0.2 requirements content is retained in the "v0.2 Requirements (complete — retained for reference)" section below.
|
||||
|
||||
### Fix 2 — REQUIREMENTS.md REQ-DASH-01 stale active row
|
||||
|
||||
REQUIREMENTS.md:44 listed REQ-DASH-01 as `must | P1 | active` in the "Employer / Program Dashboard (v0.3)" section, but the grill's Axis 2 verdict deferred it to v0.4. The §"Out of Scope" section at line 82 already correctly marks it `deferred to v0.4`.
|
||||
|
||||
**Fix:** Updated the REQ-DASH-01 row status from `active` to `deferred-to-v0.4` and phase from `P1` to `v0.4`, and retitled the section to "(deferred to v0.4 — per GRILL-v0.3.md Axis 2)" to match the Auth & Multi-Tenancy section below it.
|
||||
|
||||
### Fix 3 (noted, not applied) — PERSONAS.md post-grill roster drift
|
||||
|
||||
PERSONAS.md still reflects the **pre-grill** v0.3 roster (5 active personas including frontend-engineer for cohort dashboard). The grill's Axis 2 verdict deferred the operator tier to v0.4, which means:
|
||||
- `frontend-engineer` should be `active: false` (no UI in v0.3 — dashboard is v0.4)
|
||||
- `security-engineer` reason should drop the "operator auth stack (server/auth/)" mention (auth is v0.4)
|
||||
- `data-engineer` reason should drop the Postgres operator-tier + k-anonymity mentions (v0.4)
|
||||
- `lead-developer` reason should drop the "Postgres service addition" mention (v0.4)
|
||||
- `backend-engineer` reason should drop cohort aggregation / operator API / asyncpg mentions (v0.4)
|
||||
|
||||
**Not auto-fixed** because PERSONAS.md is a research-stage artifact that documents the *research-time* roster reasoning. The PLAN.md §Persona load distribution (line 93-103) is the *authoritative* post-grill roster and correctly shows frontend-engineer=0 tasks, devops-engineer=0 tasks, and security-engineer=8 tasks (VC only, no auth). Marking as **W-1 non-blocking warning** — the drift is cosmetic and the PLAN is the source of truth for task assignment.
|
||||
|
||||
---
|
||||
|
||||
## 8. Critical Issues Found
|
||||
|
||||
**None.** No critical issues found. The 2 auto-fixed items were doc-drift (stale headers), not logic/data errors. The branch-hygiene warning (non-squash merge) is a process deviation, not a correctness issue — all commits are traceable with `---ci---` blocks.
|
||||
|
||||
---
|
||||
|
||||
## 9. Final Verdict
|
||||
|
||||
# ✅ HEALTHY
|
||||
|
||||
The v0.3 milestone through phase 1 (tag v0.1.4) is **healthy and ready for P2 milestone ship**:
|
||||
|
||||
- **Reconstruction:** git log matches `.ciagent/` files; 13/13 REQ-IDs implemented and verified at `v0.1.4`; checkpoint progression consistent.
|
||||
- **File discipline:** canonical names present; milestone lines all v0.3; 2 stale-header doc-drift items auto-fixed.
|
||||
- **Branch hygiene:** required branches exist; 1 warning (non-squash phase/01 merge — non-blocking, recommend squash for P2 ship).
|
||||
- **Commit discipline:** all v0.3 commits have well-formed `---ci---` blocks; conventional commits followed.
|
||||
- **Tag discipline:** v0.1.0..v0.1.4 strictly increasing, no skips, annotated, correct ship semantics.
|
||||
|
||||
**Recommendations for P2 ship:**
|
||||
1. Use `--squash` or a true 2-parent merge commit when merging phase/02 → milestone/v0.3 → main (restore the v0.2 squash-merge pattern).
|
||||
2. Update ROADMAP.md phase 0 + phase 1 status lines from `in-progress`/`planned` to `complete` during P2 ship.
|
||||
3. Update PERSONAS.md roster to post-grill state during v0.4 phase 0 (not blocking v0.3 ship).
|
||||
4. Update CHECKPOINT.json to `phase:2, stage:complete, milestone_complete:true` after v0.1.5 tag.

# Praxis v0.3 CIAgent Plan — GRILL Verdict (Red-Team Review)
|
||||
|
||||
> **Reviewer:** adversarial technology executive (red-team)
|
||||
> **Subject:** v0.3 execution plan (Mastery Scoring + Competency Rubrics) — 2 phases, 15 slices, 70 tasks
|
||||
> **Stance:** plan is unfeasible, over-scoped, and too costly until evidence forces otherwise
|
||||
> **Date:** 2026-08-03
|
||||
> **Binding status:** This GRILL verdict must be cleared (MUSTs resolved, FIXs tracked) before EXECUTE is authorized.
|
||||
> **Artifacts reviewed:** PLAN.md, PROJECT.md, REQUIREMENTS.md, RESEARCH.md (v0.3 section), ARCHITECTURE.md (v0.3 section), ROADMAP.md
|
||||
|
||||

|
||||
|
||||
## Verdict Legend
|
||||
|
||||
- **MUST** — blocks execution until fixed. The plan cannot enter EXECUTE with this issue open.
|
||||
- **FIX** — fix during execution, non-blocking. Tracked as a P1 condition in VERIFY.
|
||||
- **ACCEPT** — proceed as-is. The evidence clears the challenge.
|
||||
|
||||
---
|
||||
|
||||
## Axis 1 — Feasibility
|
||||
|
||||
**Forcing question:** Can this actually be built in 2 execution phases (70 tasks)? Is the scope realistic for one milestone, or is it 2 milestones pretending to be one?
|
||||
|
||||
**Challenge:** The v0.3 scope spans *seven* independent subsystems (rubric/mastery engine, IRT, scenario library + ≥6 authored scenarios, 6-week path engine, W3C VC 2.0 issuer with Ed25519 + Status List, operator auth + argon2id + slowapi, Postgres-in-LXC + asyncpg, cohort dashboard + k-anonymity aggregation + React UI). This is not a milestone — it is a *program*. The PLAN.md phase-split rationale (lines 14-23) openly admits the scope "is too large for one execution phase" and splits into P1/P2, but both phases ship under the *same* v0.3 milestone tag (v0.1.6). The 70-task count is artificially compressed: SLICE-12 (VC issuer) is 6 tasks for a W3C VC 2.0 + Ed25519 + JCS + Bitstring Status List + public verification endpoint + key rotation — that is *at minimum* a 10-12 task slice on its own, and SLICE-13 (cohort aggregation with k-anonymity + nightly reconciliation + on-session-end hook) is similarly under-tasked at 4 tasks.
|
||||
|
||||
**Evidence:**
|
||||
- PLAN.md:14-23 — "The v0.3 scope … is too large for one execution phase."
|
||||
- PLAN.md:32, 334 — P1 = 38 tasks, P2 = 32 tasks, total 70 (excludes P3 review).
|
||||
- REQUIREMENTS.md:20-66 — 11 functional REQ-IDs + 9 NFRs = 20 active requirements, the largest single-milestone REQ surface in the project's history (v0.1 was ~14, v0.2 was 16 deploy + 4 NFR).
|
||||
- RESEARCH.md:769 (R-VC-01) — "No batteries-included Python VC lib → ~200 LOC custom code" — 200 LOC of custom crypto code is not a 6-task slice; it is a liability that demands more tests than the plan allocates (only 2 test tasks: TASK-12-05, TASK-12-06).
|
||||
- SLICE-13 (PLAN.md:516-546) — 4 tasks for: on-session-end hook, k-anonymity suppression SQL, nightly reconciliation cron, and tests. The nightly reconciliation job alone (recompute all 7-day windows from raw events, correct drift, idempotent upsert) is a 2-3 task effort.
|
||||
|
||||
**Binding verdict: FIX** — The plan *is* feasible as a 2-phase *program*, but only if it is honestly re-labeled. The milestone should ship as v0.3 (P1 mastery core, v0.1.4) and v0.3.1 (P2 operator tier, v0.1.5), with the v0.3 milestone release (v0.1.6) being the *merge* of two separately-shipped, separately-verified patches. Do not pretend P1+P2 is one milestone release. Additionally, re-task SLICE-12 and SLICE-13: add 2 tasks each (one for VC Status List edge cases + key rotation drill, one for reconciliation idempotency + race-condition test). This is non-blocking — the wave structure survives — but the task counts must be honest before EXECUTE.
|
||||
|
||||
---
|
||||
|
||||
## Axis 2 — Scope
|
||||
|
||||
**Forcing question:** Is REQ-DASH-01 (cohort dashboard + multi-tenant + auth) really v0.3, or was it correctly deferred in v0.1/v0.2 for a reason? Does D-031 (override D-007) open a Pandora's box?
|
||||
|
||||
**Challenge:** REQ-DASH-01 was explicitly deferred in v0.1 (REQUIREMENTS.md:152, "later/deferred") and v0.2. ROADMAP.md:94 places the "Employer / program dashboard" at **v0.8**. The v0.3 plan pulls it forward *three milestones* with the justification that mastery scoring "needs" the operator view. But mastery scoring (REQ-MAST-01/02) and VC issuance (REQ-MAST-03) work *without* a cohort dashboard — the dashboard is an *operator* feature, not a *learner* feature. D-031 overrides D-007 (single-learner/no-auth) and introduces a hybrid SQLite+Postgres topology, operator auth, argon2id, slowapi, asyncpg, a second Docker service, k-anonymity aggregation, and a React operator UI — *none* of which is required for the learner-facing mastery gate to function. This is scope creep dressed as a dependency.
|
||||
|
||||
**Evidence:**
|
||||
- ROADMAP.md:94 — "v0.8 | Employer / program dashboard" (original placement).
|
||||
- PROJECT.md:129 (D-031) — "overrides D-007 for the cohort-dashboard surface" — confidence 0.75, the *lowest*-confidence decision that expands scope.
|
||||
- REQUIREMENTS.md:44 (REQ-DASH-01) — "Forces multi-tenant + operator auth (D-031)" — the word "forces" is doing a lot of work. The mastery gate (REQ-MAST-02) does not depend on the dashboard.
|
||||
- PLAN.md:18 — P1 "works standalone (learner can practice, score, progress) without the operator tier." — *This is an admission that the operator tier is separable.*
|
||||
- PROJECT.md:147 (D-049) — failure-injection stays off, further confirming the learner-facing mastery layer is the *real* v0.3 deliverable.
|
||||
|
||||
**Binding verdict: MUST** — Split the milestone. Ship **v0.3 = P1 only** (mastery core + IRT + scenarios + paths + VC issuance, since VC issuance *is* triggered by the mastery gate and is learner-facing per D-048). Defer **REQ-DASH-01 + REQ-AUTH-01 + REQ-MT-01/02 + REQ-NFR-DASH-01/02 + REQ-NFR-AUTH-01 + REQ-NFR-MT-01** to **v0.4** (operator tier), restoring the original ROADMAP intent. D-031 does open a Pandora's box: every hybrid-DB system eventually faces the "which store is the source of truth?" question, and shipping it under a learner-milestone tag hides that risk. If the team insists on keeping the dashboard in v0.3, rebrand the milestone as "v0.3: Mastery + Operator Tier" and accept that this is a 2-milestone program — but the cleaner answer is to defer the dashboard.

## Axis 3 — Cost
|
||||
|
||||
**Forcing question:** What is the maintenance cost of Postgres-in-LXC, asyncpg, argon2, pynacl, slowapi, and ~200 LOC custom VC code? Is R-VC-01 (custom VC code) a liability vs using a library?
|
||||
|
||||
**Challenge:** The v0.3 dependency surface grows by *at least* 5 new pip packages (asyncpg, argon2-cffi, slowapi, pynacl, canonicaljson, base58 — actually 6) plus a Postgres service. Each is a CVE vector, a version-pin maintenance burden, and a CI complexity adder. The ~200 LOC custom VC code (R-VC-01) is the most concerning: cryptographic code written by an AI agent is a *liability* regardless of test coverage. The W3C VC 2.0 + eddsa-jcs-2022 cryptosuite has subtle canonicalization edge cases (e.g., JSON number representation, key ordering, URI normalization) that unit-test round-trips do *not* catch — only interop tests against an independent verifier do, and the plan has *zero* interop tests.
|
||||
|
||||
**Evidence:**
|
||||
- RESEARCH.md:769 (R-VC-01) — "~200 LOC custom code" — confidence 0.75. The mitigation is "unit-test signature/verify round-trip," which only proves the code is self-consistent, not that it is W3C-compliant.
|
||||
- PLAN.md:504-513 (TASK-12-05, TASK-12-06) — VC tests are sign/verify round-trip, tamper detection, JCS determinism, status list, revocation, key rotation. *No interop test against an external verifier* (e.g., Verifiable Credential JS verifier, Digital Credentials Verifier).
|
||||
- PROJECT.md:140 (D-042) — issuer key encrypted at rest with a root key from secrets. Key management is hand-rolled (init_issuer_key, encrypt, store, rotate). This is a security-engineer task, not a backend task, and the plan assigns it to security-engineer (good), but the *rotation drill* (D-042 "new key + old marked superseded") is not tested end-to-end except in TASK-12-06 which only checks "old VC still verifies against archived public key" — it does *not* test the operational rotation procedure (generate new key, archive old, re-sign new VCs, update verificationMethod URL).
|
||||
- RESEARCH.md:772 (R-MT-01) — Postgres-in-LXC resource contention, confidence 0.65 — the *lowest*-confidence technical risk. Memory bump to 6GB is a guess, not a measurement.
|
||||
|
||||
**Binding verdict: MUST** — Two conditions before EXECUTE:
|
||||
1. **Add a VC interop test** (TASK-12-07): verify a Praxis-issued VC against at least one *external* W3C VC verifier (e.g., the `digitalbazaar/vc-verifier` or a JS `@digitalcredentials/vc` verifier). Round-trip self-verification is insufficient for cryptographic claims. Without this, R-VC-01 is an unmitigated liability.
|
||||
2. **Add a key-rotation operational test** (TASK-12-08): end-to-end drill — issue N VCs with key A, rotate to key B, issue M VCs with key B, verify all N+M VCs still verify (N against archived key A, M against active key B), revoke one of each, verify revocation. This is the *one* crypto procedure that, if broken, silently invalidates every credential ever issued.
|
||||
|
||||
The Postgres/argon2/slowapi maintenance cost is **ACCEPT** — these are well-maintained, widely-used libraries. The liability is concentrated in the custom VC code.
|
||||
|
||||
---
|
||||
|
||||
## Axis 4 — Technical Risk
|
||||
|
||||
**Forcing question:** R-MAST-01 (N=3 thin for credential), R-AUTH-01 (Secure cookie + no TLS), R-MAST-02 (LLM hallucinated quotes), R-IRT-01 (cold start) — which are MUST-FIX before execution vs ACCEPT?
|
||||
|
||||
**Challenge:** The plan treats all four as "Open Questions Deferred to EXECUTE" (PLAN.md:687-693). That is insufficient. R-MAST-01 is a *credibility* risk: if the VC is labeled as a mastery credential and employers treat it as high-stakes, N=3 with G≈0.5-0.6 is defensible only if the credential is explicitly labeled *formative*. R-AUTH-01 is a *security* risk: relaxing the Secure cookie flag for a no-TLS pilot means session cookies travel in cleartext — if the operator bridge IP is on a shared network (vmbr0 DHCP), any host on the bridge can sniff the operator session. R-MAST-02 is the *highest*-confidence mitigation (fuzzy-match quotes), but the plan's fallback ("empty evidence + log warning") means a session could silently score as a *zero* with no learner-visible signal. R-IRT-01 is benign (cold-start fallback to fixed difficulty).
|
||||
|
||||
**Evidence:**
|
||||
- RESEARCH.md:766 (R-MAST-01) — confidence 0.62, *below* the 0.70 decision threshold. Mitigation: "Label v0.3 VC as formative." This label is *not* in the PLAN.md VC payload (TASK-12-02) or the REQ-MAST-03 requirement text.
|
||||
- RESEARCH.md:771 (R-AUTH-01) — "Secure cookie flag fails without TLS." PLAN.md:450 resolves this with `PRAXIS_COOKIE_SECURE=false` env default. This ships a known-insecure default.
|
||||
- PLAN.md:154 (TASK-03-01) — "on final failure, fall back to empty evidence + log warning." Empty evidence → rule scorer has no signals → every criterion scores level 1 (fail) → scenario fails → learner sees a failed session with *no explanation*. This is a UX and fairness bug.
|
||||
- RESEARCH.md:774 (R-IRT-01) — mitigation confidence 0.75, "fall back to scenario.difficulty until ≥5 observations." ACCEPT.
|
||||
|
||||
**Binding verdict: MUST** — Three conditions:
|
||||
1. **R-MAST-01**: Add `credentialTier: "formative"` (or equivalent) to the VC payload (TASK-12-02) and to the verification endpoint response (TASK-12-04). Update REQ-MAST-03 to require this label. Without it, the credential is misleading.
|
||||
2. **R-AUTH-01**: Do *not* ship `PRAXIS_COOKIE_SECURE=false` as a default. Either (a) require TLS for the operator surface (add a Traefik sidecar or Caddy in front of `/api/operator/*`), or (b) bind the operator surface to `127.0.0.1` only (loopback) so cookies never traverse the bridge. A cleartext cookie on a shared bridge is a MUST-FIX.
|
||||
3. **R-MAST-02**: Change the fallback in TASK-03-01 from "empty evidence + log warning" to "empty evidence → mark scenario as `scoring_inconclusive` → do not count toward gate, do not penalize learner, surface 'technical issue, please retry' in the debrief." A silent fail-to-zero is unacceptable.
|
||||
|
||||
R-IRT-01: **ACCEPT** — cold-start fallback is sound.
|
||||
|

|
||||
|
||||
## Axis 5 — Requirements Coverage
|
||||
|
||||
**Forcing question:** Does the plan actually cover all 20 REQ-IDs, or are some hand-waved? Check the coverage matrix in PLAN.md against REQUIREMENTS.md.
|
||||
|
||||
**Challenge:** The PLAN.md coverage matrix (lines 657-683) claims "20 REQ-IDs covered, 0 partial, 0 deferred." Let me audit the suspicious ones.
|
||||
|
||||
**Evidence (audit):**
|
||||
|
||||
| REQ-ID | Claimed coverage | Actual coverage | Verdict |
|
||||
|--------|-----------------|-----------------|---------|
|
||||
| REQ-MAST-03 | P2 SLICE-12 "VC issuer" | SLICE-12 implements issuance + verification + revocation. But REQ-MAST-03 says "Issued when a mastery gate opens" — the *trigger* is in P1 SLICE-07 (TASK-07-01, "path_engine.check_gate + advance_week") and the *issuance* is in P2 SLICE-12. The P1→P2 handoff for VC issuance is not in any task — who calls `issuer.issue_credential()` when the week-final gate opens? TASK-07-01 says "(6) record mastery_gate_event" but does NOT call the VC issuer (VC issuer is P2). D-048 says "issue VC if week-final gate" but the plan splits the gate-open (P1) from the issuance (P2). **Gap: no task wires the P1 gate-open event to the P2 VC issuer.** | **FIX** — add a task (either in SLICE-07 or SLICE-12) that defines the P1→P2 VC-issuance contract: a `mastery_gate_events` row with `gate_opened_at` is the trigger; P2's VC issuer polls/receives this event and issues. |
|
||||
| REQ-NFR-MAST-02 | P1+P2 SLICE-07, 09 "gate auditability (SQLite + Postgres)" | SLICE-07 records the event in SQLite; SLICE-09 defines the Postgres `mastery_gate_events` table; but *no task mirrors* the SQLite event to Postgres. The "mirror" is implied but not tasked. | **FIX** — TASK-13-01 (cohort aggregation hook) should explicitly mirror `mastery_gate_events` from SQLite to Postgres, or add a dedicated mirroring task. |
|
||||
| REQ-SCEN-04 | P1 SLICE-02, 06 "expert-authored format + AI variation hooks" | SLICE-02 adds `generated_from` and `intent_hash` fields (the hook). SLICE-06 authors expert scenarios. But *no task implements the AI-variation review pipeline* (`_pending/` dir → expert review → library promotion). RESEARCH.md:758 describes it; PLAN.md does not task it. | **ACCEPT** — REQ-SCEN-04 says "AI-generated variations" with "expert review" — the *hook* is the schema field; the *pipeline* can be deferred. The plan is honest that AI variations are "in P2 or later" (SLICE-06 goal line 246). |
|
||||
| REQ-NFR-DASH-02 | P2 SLICE-13 "freshness ≤24h" | SLICE-13 has a nightly reconciliation job (TASK-13-03) at 02:00. If the on-session-end hook (TASK-13-01) fails or lags, freshness depends on the nightly job. ≤24h is satisfied *if* the nightly job runs. But there is no task for *monitoring* or *alerting* on job failure. | **FIX** — add a health check for the nightly job (log last-run timestamp, surface in operator dashboard or `/health`). Non-blocking. |
|
||||
| REQ-NFR-VC-02 | P2 SLICE-12 "revocation latency — within 1 sync of status list" | "1 sync" is undefined. Is it 1 sync of the status list blob? Is the status list in-memory or fetched on every verify? TASK-12-04 (verification endpoint) does not specify caching of the status list. | **FIX** — clarify in TASK-12-04: status list is fetched from Postgres on every verification (no cache), so revocation latency = next verify call. Non-blocking. |
|
||||
|
||||
**Binding verdict: FIX** — The coverage matrix is *mostly* honest (18/20 fully covered), but the P1→P2 VC-issuance wiring gap (REQ-MAST-03) is a real hole — without a task that defines the trigger contract, the VC issuer will be built but never called. Add the wiring task. The other three FIXs are minor clarifications.
|
||||
|
||||

|
||||
|
||||
## Axis 6 — Architecture
|
||||
|
||||
**Forcing question:** Is hybrid SQLite + Postgres (D-031) a maintainable pattern or a future migration nightmare? Is "no cross-DB joins" realistic for the cohort dashboard queries?
|
||||
|
||||
**Challenge:** Hybrid polyglot persistence is a *known* anti-pattern when the two stores hold related data and there is no canonical source of truth. Here, `mastery_gate_events` exists in *both* SQLite (P1, the learner's local record) and Postgres (P2, the operator audit log). Which is canonical? If they diverge (e.g., SQLite write succeeds, Postgres mirror fails due to pool exhaustion), the cohort dashboard shows *stale* data while the learner sees *correct* data — and there is no reconciliation except the nightly job (which recomputes from Postgres `mastery_gate_events`, not from SQLite). This means the nightly job recomputes from a *possibly-incomplete* Postgres copy. The "no cross-DB joins" rule is realistic *only* if the cohort dashboard never needs to join learner-local data (e.g., θ distribution by path) with operator data — but the dashboard's "progression" and "failure patterns" views implicitly need *both* the learner's session outcomes (SQLite) and the operator's aggregate view (Postgres). The plan resolves this by aggregating at session-end (writing the aggregate to Postgres), so the dashboard reads *only* Postgres — but this means the aggregate is a *derived* copy, and the "no cross-DB joins" rule is maintained by *duplicating data*, not by query-time joins. This is workable but fragile.
|
||||
|
||||
**Evidence:**
|
||||
- ARCHITECTURE.md:356-379 — "The two stores never share a session and never join via cross-DB FKs (`learner_ref` is an opaque string in Postgres)." — the design is clean *if* the mirror is reliable.
|
||||
- RESEARCH.md:746 — "No cross-DB joins via `learner_ref` — `learner_ref` is an opaque string, not a FK." — correct, but `learner_ref` is still a *logical* join key. If the SQLite learner is deleted and re-created, the Postgres `learner_ref` dangles.
|
||||
- PLAN.md:528-529 (TASK-13-01) — "after P1's mastery hooks fire, call `aggregator.upsert_aggregate(...)`" — this is a *synchronous* call after the SQLite write, in the session-end path. If Postgres is down, does the session-end fail? The plan does not specify failure semantics.
|
||||
- RESEARCH.md:748 — migration strategy: "SQLite volume untouched → learner path never regresses." Good, but the *operator* path regresses if Postgres is down.
|
||||
|
||||
**Binding verdict: FIX** — Three conditions:
|
||||
1. **Define failure semantics for the Postgres mirror** (in TASK-13-01): if `upsert_aggregate` fails (Postgres down, pool exhausted), the learner session-end must *still succeed* (SQLite write is canonical for the learner). The aggregate failure is logged and reconciled by the nightly job. This makes SQLite the *learner-canonical* store and Postgres the *operator-derived* store — state this explicitly in ARCHITECTURE.md.
|
||||
2. **Make `learner_ref` a stable, opaque, non-reusable identifier** (e.g., a UUID generated once and stored in SQLite, never reused). Add this to TASK-02-01 or a new task. Without it, the "no FK" rule is a leaky abstraction.
|
||||
3. **Add a Postgres-readiness guard to the operator API**: if Postgres is down, `/api/operator/cohort/*` returns 503 (not 500 with a stack trace). Add to TASK-14-02.
|
||||
|
||||
The hybrid pattern is **ACCEPT** *with* these conditions — it is the correct pilot choice (don't migrate learner state to Postgres prematurely), but the failure semantics must be explicit.
|
||||
|

|
||||
|
||||
## Axis 7 — Testing
|
||||
|
||||
**Forcing question:** 70 tasks, but how many have tests? Is the test strategy (mocked LLM for evidence extraction, testcontainers for Postgres) viable, or are there untestable critical paths?
|
||||
|
||||
**Challenge:** Let me count test tasks across the plan.
|
||||
|
||||
**Evidence (test task audit):**
|
||||
|
||||
| Slice | Tasks | Test tasks | Test ratio |
|
||||
|-------|-------|-----------|------------|
|
||||
| SLICE-01 | 4 | 1 (TASK-01-04) | 25% |
|
||||
| SLICE-02 | 4 | 1 (TASK-02-04) | 25% |
|
||||
| SLICE-03 | 5 | 2 (TASK-03-04, 03-05) | 40% |
|
||||
| SLICE-04 | 4 | 2 (TASK-04-03, 04-04) | 50% |
|
||||
| SLICE-05 | 4 | 1 (TASK-05-04) | 25% |
|
||||
| SLICE-06 | 3 | 1 (TASK-06-03) | 33% |
|
||||
| SLICE-07 | 4 | 2 (TASK-07-03, 07-04) | 50% |
|
||||
| SLICE-08 | 3 | 3 (all test/verification) | 100% |
|
||||
| SLICE-09 | 4 | 1 (TASK-09-04) | 25% |
|
||||
| SLICE-10 | 3 | 0 | 0% — infra, acceptable |
|
||||
| SLICE-11 | 5 | 2 (TASK-11-04, 11-05) | 40% |
|
||||
| SLICE-12 | 6 | 2 (TASK-12-05, 12-06) | 33% — *too low for crypto code* |
|
||||
| SLICE-13 | 4 | 1 (TASK-13-04) | 25% — *too low for k-anonymity* |
|
||||
| SLICE-14 | 4 | 1 (TASK-14-04) | 25% |
|
||||
| SLICE-15 | 4 | 1 (TASK-15-04) | 25% |
|
||||
| SLICE-16 | 3 | 3 (all integration/verification) | 100% |
|
||||
| **Total** | **70** | **24** | **34%** |
|
||||
|
||||
**Critical untestable paths:**
|
||||
1. **LLM evidence extraction (TASK-03-01)** — the plan mocks the LLM (good for unit tests), but there is *no* test that runs against the *real* LLM with a real transcript. A mocked LLM proves the scoring logic, not that the extraction prompt works. This is a *fundamentally untestable in CI* path — the only test is manual/staging.
|
||||
2. **k-anonymity suppression (TASK-13-02)** — the test (TASK-13-04) checks "cell with 9 learners → suppressed, 10 → shown." But it does *not* test the differencing attack (comparing two adjacent windows to re-identify a learner who appears in one but not the other). RESEARCH.md:754 says "limit to pre-defined 2-D views to block differencing attacks" — but there is no test that the API *enforces* only pre-defined views (i.e., that an operator cannot request an arbitrary `path × week × outcome` 3-D view).
|
||||
3. **Nightly reconciliation (TASK-13-03)** — no test for "reconciliation corrects drift." TASK-13-04 tests "reconciliation correctness" but not *drift correction* (insert a bad aggregate, run reconcile, verify it's fixed).
|
||||
4. **VC verification endpoint (TASK-12-04)** — tested via TASK-12-06, but only with Praxis-issued VCs. No interop test (see Axis 3).
|
||||
|
||||
**Binding verdict: FIX** — Four conditions:
|
||||
1. **Add a real-LLM smoke test** (in SLICE-08 or SLICE-16): run one session transcript through the *actual* deepseek-v4-flash:cloud evidence extractor and verify the output is valid JSON with fuzzy-matching quotes. This runs only in staging (requires OLLAMA_API_KEY), gated by an env flag. The mocked-LLM tests stay in CI.
|
||||
2. **Add a k-anonymity differencing-attack test** (TASK-13-04 extension): verify that the cohort API rejects arbitrary 3-D view requests, and that two adjacent 7-day windows cannot re-identify a single learner appearing in only one.
|
||||
3. **Add a reconciliation drift-correction test** (TASK-13-04 extension): insert a deliberately-wrong aggregate, run `reconcile_cohort()`, verify it's corrected.
|
||||
4. **Add the VC interop test** (per Axis 3, MUST condition).
|
||||
|
||||
The mocked-LLM + testcontainers strategy is **ACCEPT** *for CI*. The gaps are in *integration* and *security* testing, not unit testing.
|
||||
|
||||

|
||||
|
||||
## Axis 8 — Phase Split
|
||||
|
||||
**Forcing question:** Is P1/P2 the right split? Should VC issuance (P2 SLICE-12) be in P1 with mastery gates (P1 SLICE-07) since they trigger on the same event? Is the P1→P2 dependency clean?
|
||||
|
||||
**Challenge:** The plan splits VC issuance (P2) from mastery-gate-open (P1) even though D-048 says "issue VC if week-final gate." This means P1 ships (v0.1.4) with mastery gates that open but *no credential is issued* — the learner reaches mastery and gets... nothing portable. The VC issuer arrives in P2 (v0.1.5). This is a *user-visible gap*: a learner who completes the path in v0.1.4 has no credential. The plan's phase-split rationale (lines 14-23) says P1 "works standalone (learner can practice, score, progress) without the operator tier" — but VC issuance is *not* the operator tier; it is a learner-facing consequence of mastery (D-048). VC issuance should be in P1.
|
||||
|
||||
Conversely, the operator auth + Postgres + cohort dashboard is correctly P2 — those are operator-tier.
|
||||
|
||||
**Evidence:**
|
||||
- PROJECT.md:146 (D-048) — "issue VC if week-final gate" — VC issuance is a *mastery-gate consequence*, not an operator feature.
|
||||
- PLAN.md:18 — "P1 works standalone" — but "standalone" here silently drops the VC, which is a REQ-MAST-03 requirement.
|
||||
- PLAN.md:663 (coverage matrix) — REQ-MAST-03 is listed as P2 SLICE-12. But REQ-MAST-03 is a *mastery* requirement, not an *operator* requirement.
|
||||
- PLAN.md:282 (TASK-07-01) — P1 session-end hook does steps 1-6 but step 6 is "record mastery_gate_event" — no VC issuance call. The VC issuance is orphaned in P2 with no trigger from P1.
|
||||
|
||||
**Binding verdict: MUST** — Move SLICE-12 (VC issuer) to **P1**, *after* SLICE-07 (mastery gates), as a new Wave-4 slice in P1 (parallel with SLICE-08). This requires:
|
||||
1. VC issuer needs `issuer_keys` storage — use *SQLite* for P1 (the issuer_keys table moves to SQLite for v0.3; Postgres takes over in v0.4 when the operator tier arrives). Or, if Postgres is required for VC, then Postgres must also move to P1 — which inflates P1 further and reinforces the Axis 2 verdict (split the milestone).
|
||||
2. The cleaner resolution: **defer VC issuance to v0.3.1 (P2)** *and* accept that v0.1.4 (P1) ships mastery gates without credentials — but *label this explicitly* in the P1 ship notes ("VC issuance in v0.1.5"). Do not claim REQ-MAST-03 is covered in P1.
|
||||
|
||||
Either resolution is acceptable. The *current* plan — which implies VC issuance is triggered by P1's gate-open but tasks it in P2 with no wiring — is **not acceptable**. Pick one: (a) VC in P1 with SQLite-backed issuer keys, or (b) VC explicitly deferred to P2 with P1 shipping "mastery gates, no credential yet."
|
||||
|
||||
The P1→P2 dependency is otherwise clean (P2 reads P1's `mastery_gate_events` and session outcomes). **ACCEPT** on the dependency structure.
|
||||
|
||||

|
||||
|
||||
## Axis 9 — Decisions
|
||||
|
||||
**Forcing question:** Are D-031..D-049 (12 clarify + 7 specify decisions) well-grounded, or are any below the 0.60 confidence threshold? Is D-049 (failure-injection stays off) a mistake given mastery scoring scores recovery from failure branches?
|
||||
|
||||
**Challenge:** Let me audit confidences against the 0.70 threshold (the project's apparent decision-acceptance floor).
|
||||
|
||||
**Evidence (confidence audit of D-031..D-049):**
|
||||
|
||||
| ID | Confidence | Below 0.70? | Verdict |
|
||||
|----|------------|-------------|---------|
|
||||
| D-031 | 0.75 | No | ACCEPT — but see Axis 2 (scope creep). |
|
||||
| D-032 | 0.70 | At threshold | ACCEPT — N=3 is formative-only per R-MAST-01. |
|
||||
| D-033 | 0.70 | At threshold | ACCEPT — W3C VC 2.0 is a stable standard. |
|
||||
| D-034 | 0.70 | At threshold | ACCEPT — k=10 is the conventional minimum. |
|
||||
| D-035 | 0.70 | At threshold | ACCEPT — 1PL/Rasch is the simplest IRT. |
|
||||
| D-036 | 0.80 | No | ACCEPT. |
|
||||
| D-037 | 0.75 | No | ACCEPT. |
|
||||
| D-038 | 0.80 | No | ACCEPT — deterministic scoring is the right call. |
|
||||
| D-039 | 0.80 | No | ACCEPT. |
|
||||
| D-040 | 0.80 | No | ACCEPT. |
|
||||
| D-041 | 0.75 | No | ACCEPT — but R-AUTH-01 (Secure cookie) is a MUST-FIX (Axis 4). |
|
||||
| D-042 | 0.70 | At threshold | ACCEPT — but key rotation drill is a MUST (Axis 3). |
|
||||
| D-043 | 0.80 | No | ACCEPT. |
|
||||
| D-044 | 0.75 | No | ACCEPT. |
|
||||
| D-045 | 0.70 | At threshold | ACCEPT — but failure semantics are a FIX (Axis 6). |
|
||||
| D-046 | 0.80 | No | ACCEPT — θ in SQLite is correct. |
|
||||
| D-047 | 0.70 | At threshold | ACCEPT — 6 scenarios is tight but defensible for formative. |
|
||||
| D-048 | 0.75 | No | ACCEPT — but the P1/P2 split breaks the trigger wiring (Axis 8). |
|
||||
| D-049 | 0.80 | No | See below. |
|
||||
|
||||
**D-049 (failure-injection stays off):** The challenge is whether this is a mistake. The rubric (SLICE-01) has a "de-escalation" criterion (weight 0.20), and RESEARCH.md:718 says "de-escalation up-weights to ~0.40 if the escalate branch triggers." The `escalate` branch is a *naturally-occurring* failure branch in `cs_refund_ca_v01` (D-010), not an AI-provoked failure. So mastery scoring *does* score recovery from a failure branch — the *naturally-occurring* one. D-049 keeps AI-provoked failure injection off, which is correct: the rubric's de-escalation criterion is exercised by the existing branch, and adding AI-provoked failures would couple mastery scoring to a new feature (scope creep). D-049 is well-grounded.
|
||||
|
||||
**However**, there is a subtle gap: the rubric weights are *static* in the YAML (empathy 0.35, resolution 0.30, de-escalation 0.20, professionalism 0.15 per TASK-01-01). RESEARCH says de-escalation "up-weights to ~0.40 if the escalate branch triggers" — but TASK-01-01 does not mention dynamic re-weighting based on branch outcome. Either the weights are static (and the "up-weight" is a future feature) or they are dynamic (and the plan is missing a task). This is a **FIX** — clarify in TASK-01-01 whether weights are static or branch-dependent. If static, update RESEARCH.md to note the up-weight is deferred.
|
||||
|
||||
**Binding verdict: ACCEPT** on all D-031..D-049 confidences (none below 0.60; the floor is 0.70, which is the project's threshold). **FIX** on the de-escalation weight ambiguity (static vs dynamic) in TASK-01-01. D-049 is **ACCEPT** — failure-injection stays off is the correct call; the naturally-occurring `escalate` branch exercises the de-escalation criterion.

|
||||
|
||||
---
|
||||
|
||||
## Final Recommendation: **GO-WITH-CONDITIONS**
|
||||
|
||||
The v0.3 plan is **not approved for EXECUTE as-is**. It is a well-researched, well-structured plan that suffers from two structural flaws: (1) it is two milestones pretending to be one, and (2) it splits a learner-facing consequence (VC issuance) from its trigger (mastery gate) across a phase boundary without wiring.
|
||||
|
||||
### MUST conditions (blocking — must be resolved in PLAN before EXECUTE):
|
||||
|
||||
1. **Axis 2 — Split the milestone.** Either (a) defer REQ-DASH-01 + operator tier to v0.4, shipping v0.3 = P1 + VC issuance only; or (b) rebrand v0.3 as a 2-milestone program (v0.3 + v0.3.1) with separate ship/verify cycles. Do not ship P1+P2 under one milestone tag.
|
||||
|
||||
2. **Axis 3 — Add VC interop test + key-rotation operational test.** Custom crypto code without interop verification is an unmitigated liability. Add TASK-12-07 (interop) and TASK-12-08 (rotation drill).
|
||||
|
||||
3. **Axis 4 — Fix three technical risks.** (a) Label VC as `formative` in payload + verification response + REQ-MAST-03 text. (b) Do not ship `PRAXIS_COOKIE_SECURE=false` as default — use TLS or loopback-binding for the operator surface. (c) Change evidence-extraction fallback from silent-fail-to-zero to `scoring_inconclusive` with learner-visible retry signal.
|
||||
|
||||
4. **Axis 8 — Resolve the VC-issuance phase split.** Either move SLICE-12 to P1 (with SQLite-backed issuer keys) or explicitly defer REQ-MAST-03 to P2 and label P1 as "mastery gates, no credential yet." The current plan's implicit wiring is a gap.
|
||||
|
||||
### FIX conditions (non-blocking — tracked in VERIFY-P1/P2):
|
||||
|
||||
5. **Axis 1 — Re-task SLICE-12 and SLICE-13.** Add 2 tasks each to honestly reflect the effort (VC edge cases + rotation drill; reconciliation idempotency + race test).
|
||||
6. **Axis 5 — Wire the P1→P2 VC-issuance trigger** (if VC stays in P2) and **mirror SQLite→Postgres gate events** explicitly in TASK-13-01.
|
||||
7. **Axis 6 — Define Postgres-failure semantics** (SQLite is learner-canonical, Postgres is operator-derived); stabilize `learner_ref` as a non-reusable UUID; add 503 guard on operator API.
|
||||
8. **Axis 7 — Add four tests**: real-LLM smoke (staging-gated), k-anonymity differencing-attack, reconciliation drift-correction, VC interop (already a MUST).
|
||||
9. **Axis 9 — Clarify de-escalation weight** (static vs branch-dependent) in TASK-01-01.
|
||||
|
||||
### ACCEPT items (proceed as-is):
|
||||
|
||||
- IRT 1PL/Rasch cold-start fallback (R-IRT-01).
|
||||
- All decision confidences (D-031..D-049 ≥ 0.70, none below 0.60).
|
||||
- D-049 (failure-injection stays off) — correct call.
|
||||
- Mocked-LLM + testcontainers CI strategy.
|
||||
- Hybrid SQLite+Postgres topology (with failure-semantics FIX).
|
||||
- P1→P2 dependency structure (clean except for VC-issuance wiring).
|
||||
|
||||
### Bottom line:
|
||||
|
||||
The plan is **not unfeasible** — the research is thorough, the architecture is sound, and the slice decomposition is reasonable. But it is **over-scoped** (two milestones in one tag) and **under-tested** in its highest-risk areas (custom crypto, k-anonymity, real-LLM extraction). Resolve the 4 MUST conditions, track the 5 FIX conditions, and this becomes a **GO**.

# CIAgent Grill Report — v0.4 Operator Tier
|

## Run: 2026-08-04 (mode: mechanical, focus: all axes + 6 v0.4-specific probes)
|
||||
|
||||
> **Reviewer:** adversarial technology executive (red-team)
|
||||
> **Subject:** v0.4 execution plan (Operator Tier — Cohort Dashboard + Auth + Postgres) — 2 execution phases, 10 slices, 52 tasks
|

> **Stance:** plan is unfeasible, over-scoped, and too costly until evidence forces otherwise
|

> **Binding status:** This grill verdict must be cleared (MUSTs resolved, FIXs tracked) before EXECUTE is authorized.
|
||||
|
||||
---
|
||||
|
||||
### Verdict: Proceed-with-conditions (confidence: 0.72)
|
||||
|
||||
The v0.4 plan is well-researched, cleanly phased, and honors the v0.3 grill's binding verdict (operator tier deferred, formative label applied, scoring_inconclusive fallback implemented, VC interop + key-rotation drills shipped in v0.3 codebase — all verified). The architecture is sound and the risk register is the most honest in the project's history (20 risks, 1 high, 9 medium, 11 low — all addressed). However, three material issues must be resolved before EXECUTE: (1) R-AUTH-01 is a *partial* resolution that re-litigates a v0.3 grill MUST — the config-driven flag is a punt, not a fix, and the cohort-dashboard-reads-only-aggregates defense-in-depth is the *real* mitigation, which should be elevated; (2) the k-anonymity-at-pilot-scale problem means v0.4 ships a dashboard that cannot display any data at production pilot scale (1 learner) — this is a *real deliverable* only if test-seeded data is treated as the validation path, which the plan does but does not emphasize; (3) the VC key migration verification endpoint now queries *two* stores (Postgres for keys, SQLite-fallback for v0.3 credentials) — a complexity the plan defers to "open question #1" but which is on the critical path of R-VC-MIG-01.
|
||||
|
||||
The plan is **not** over-scoped (8 REQs, cleanly split P1 infra / P2 feature). It is **not** unfeasible (52 tasks vs v0.3's 40, analogous). It is **not** a zombie (the operator tier was the explicitly-deferred v0.3 scope, now delivered). The conditions are binding but surgical.
|
||||
|
||||
---
|
||||
|
||||
### Axis 1 — Business Case
|
||||
|
||||
- **Q1: What problem does v0.4 solve, and is it the top priority?**
|
||||
- Evidence: GRILL-v0.3.md Axis 2 MUST #1 — "defer REQ-DASH-01 + operator tier to v0.4"; ROADMAP.md:9 — "v0.4 activates the operator tier deferred from v0.3 per the grill's binding verdict"; PROJECT.md:47 — "v0.4 layers the operator surface on top of it."
|
||||
- Answer: v0.4 delivers the operator tier that the v0.3 grill explicitly split out. The operator tier (cohort dashboard + auth + Postgres) was originally v0.8 on the ROADMAP (GRILL-v0.3.md:44), pulled to v0.3, then split to v0.4 by the grill. This is the *deferred obligation*, not new scope. The priority is correct: v0.3 shipped the learner-facing mastery layer; v0.4 ships the operator-facing visibility layer. The alternative (multi-path / Live Assist / low-bandwidth) would expand the learner surface before the operator surface exists to observe it.
|
||||
- Confidence: 0.85
|
||||
- Decision: **G-001** — v0.4 operator tier is the correct next priority (delivers the v0.3 grill's deferred obligation). (0.85)
|
||||
|
||||
- **Q2: Who is the named executive sponsor for the operator tier?**
|
||||
- Evidence: config.json:13 — `"level": "full"`; config.json:16 — `"decision_confidence_threshold": 0.6`; PROJECT.md:5 — "Autonomy: full."
|
||||
- Answer: No human sponsor. The CI agent is the executive sponsor under full autonomy. This is the project's established governance model since v0.1. The v0.3 grill accepted this (no escalation on governance). The "sponsor makes a decision under pressure" test is met by the grill itself — this document is the pressure decision.
|
||||
- Confidence: 0.80
|
||||
- Decision: **G-002** — CI is the named sponsor under full autonomy (no change from v0.1-v0.3 governance). (0.80)
|
||||
|
||||
- **Q3: What happens to the business if v0.4 is cancelled?**
|
||||
- Evidence: ROADMAP.md:131-139 — future milestones (v0.5 Live Assist, v0.6 low-bandwidth) do not depend on the operator tier; v0.9 credentialing depends on VC issuer (v0.3, already shipped). The learner-facing product (v0.1-v0.3) works without the operator tier.
|
||||
- Answer: If v0.4 is cancelled, the learner product continues to function. The operator tier is a *visibility* feature, not a *learner-path* feature. However, cancelling v0.4 means the v0.3 grill's binding verdict (defer to v0.4) becomes a *permanent deferral* — the operator tier was promised and not delivered. This would be the first broken grill commitment. The project is not a zombie (cancelling has a cost: the grill's credibility), but the operator tier is a nice-to-have for the pilot, not a blocker for a pilot deployment. A pilot can run with a single learner and no dashboard.
|
||||
- Confidence: 0.75
|
||||
- Challenge: The operator tier's business value at pilot scale (1 learner, k-anon suppresses everything) is low. The dashboard will show "— (<10 learners)" for every cell. This is a *placeholder deliverable* unless multi-learner data is seeded. The plan acknowledges this (Open Question #3) but does not treat it as a material risk to the business case.
|
||||
- Decision: **G-003** — v0.4 is not a zombie (delivers a grill obligation) but its pilot-scale business value is low (k-anon suppresses all cells with 1 learner). The dashboard's validation path is test-seeded data (≥10 mock learners), not pilot traffic. This must be documented in the ship notes. (0.75)
|
||||
|
||||
- **Q4: Is the ROI calculated against a counterfactual?**
|
||||
- Evidence: MISSING — no ROI calculation in any `.ciagent/` file. The project is a pre-revenue pilot (D-012 — no enforced cost ceiling for pilot).
|
||||
- Answer: No ROI calculation exists. The counterfactual is "ship v0.4 vs skip to v0.5 (Live Assist)." Shipping v0.4 costs ~52 tasks of tokens + a Postgres service + 3 new pip deps + 1 new npm dep. Skipping to v0.5 would leave the operator tier permanently deferred (broken grill commitment) and Live Assist would build on a learner surface with no operator visibility. The ROI is *governance credibility* + *operator visibility foundation for v0.5+*, not a financial return.
|
||||
- Confidence: 0.65
|
||||
- Decision: **G-004** — no financial ROI; the ROI is governance credibility (delivering the grill's deferred obligation) + architectural foundation (Postgres + auth for v0.5+). Accept the non-financial ROI under full autonomy. (0.65)
|
||||
|
||||
---
|
||||
|
||||
### Axis 2 — Scope and Requirements
|
||||
|
||||
- **Q1: Is v0.4 scope stable? (8 REQs from v0.3 grill deferral — clean handoff, or new scope creep?)**
|
||||
- Evidence: GRILL-v0.3.md Axis 2 MUST #1 — "defer REQ-DASH-01 + REQ-AUTH-01 + REQ-MT-01/02 + 4 NFRs to v0.4"; REQUIREMENTS.md:8-36 — v0.4 activates exactly those 8 REQs; PROJECT.md:49-54 — v0.4 in-scope matches the deferred set.
|
||||
- Answer: Clean handoff. The 8 REQs activated in v0.4 are exactly the 8 REQs the v0.3 grill deferred. No new REQs were added. No scope creep. The scope is *contracting* relative to the v0.3 plan (which originally included these + the mastery layer).
|
||||
- Confidence: 0.90
|
||||
- Decision: **G-005** — v0.4 scope is a clean handoff from the v0.3 grill deferral. No scope creep. (0.90)
|
||||
|
||||
- **Q2: Who owns the requirements, and are they frozen?**
|
||||
- Evidence: config.json:13 — full autonomy; PROJECT.md:5 — "Autonomy: full"; REQUIREMENTS.md:8-36 — 8 active REQs with Phase + Status columns.
|
||||
- Answer: CI owns the requirements under full autonomy. They are frozen at the SPECIFY stage (commit 1b5173e — "validate specification"). The CLARIFY stage (commit 4f565d6) added D-050..D-057 but did not add/remove REQs. Frozen.
|
||||
- Confidence: 0.85
|
||||
- Decision: **G-006** — requirements are frozen (8 REQs, CI-owned under full autonomy). (0.85)
|
||||
|
||||
- **Q3: What is explicitly out of scope?**
|
||||
- Evidence: PROJECT.md:56-65 — explicit out-of-scope list; REQUIREMENTS.md:38-48 — out-of-scope list.
|
||||
- Answer: Explicitly out of scope: multi-path launch, full operator-suite dashboard (REQ-DASH-02), Live Assist, low-bandwidth, multi-language, persona switching, learner auth, RBAC (single operator role), third-party credential issuers, differential privacy. The out-of-scope list is the most explicit in the project's history. Single operator role (no RBAC) is the key constraint — v0.4 ships one role.
|
||||
- Confidence: 0.88
|
||||
- Decision: **G-007** — out-of-scope is explicit and comprehensive (RBAC, learner auth, DP, multi-path all deferred). (0.88)
|
||||
|
||||
- **Q4: Hidden requirements? (TLS for secure cookies? Postgres backup verification? Operator account lifecycle — deactivation, password reset?)**
|
||||
- Evidence: RESEARCH-v0.4 §2.4 — R-AUTH-01 acknowledges the Secure-cookie+no-TLS tension; D-055 — backup strategy defined (pg_dump, 7-day retention); D-052 — operator bootstrap CLI; PROJECT.md:62 — "RBAC deferred (one role)."
|
||||
- Answer:
|
||||
- **TLS for secure cookies**: NOT a hidden requirement — it is the explicit R-AUTH-01 tension, resolved (partially) by config-driven `PRAXIS_COOKIE_SECURE`. See Axis 3 + signature probe.
|
||||
- **Postgres backup verification**: The plan defines a backup strategy (TASK-02-03 — backup cron script) but **does NOT define a backup verification / restore drill**. The script comments mention `pg_restore --clean --if-exists` but there is no task that *executes* a restore and verifies data integrity. A backup that is never restored is an unverified backup. This is a hidden requirement.
|
||||
- **Operator account lifecycle (deactivation, password reset)**: D-052 defines bootstrap (creation) + a `--update` flag (password rehash). The `operators` table has `is_active` (TASK-03-04 handles inactive → 401). But **there is no operator deactivation task** — no CLI to set `is_active=false`, no UI for it. Password reset = `create-operator.py --update` (documented). Deactivation is a gap, but minor (single operator, can be done via SQL if needed). Not a blocker.
|
||||
- Confidence: 0.70
|
||||
- Challenge: Backup verification is a hidden requirement. A nightly pg_dump that is never restored is theater, not a backup.
|
||||
- Decision: **G-008 (MUST)** — Add a backup-restore drill task to P1 (either in SLICE-02 or SLICE-06): execute `pg_restore --clean --if-exists` against a test Postgres instance, verify the 5 tables + row counts match. This is a one-task addition. The restore drill must run at least once in CI/staging to prove the backup is valid. (0.70)
|
||||

|
||||
|
||||
### Axis 3 — Architecture and Technical Feasibility
|
||||
|
||||
- **Q1: Has the Postgres-in-LXC + asyncpg + auth + dashboard architecture been validated by operators, or only by the plan?**
|
||||
- Evidence: RESEARCH-v0.4 §1.1-1.7 — Postgres 16-slim resource footprint analysis (0.88 confidence); §2.1-2.6 — argon2id + SessionMiddleware (0.88); §4.1-4.5 — React Router + SPA fallback (0.85). No external operator validation (full autonomy — CI is the operator).
|
||||
- Answer: The architecture is validated by research (vendor docs, OWASP, ecosystem knowledge) and codebase inspection (existing `session_recorder.py:143` asyncio.create_task pattern, existing `issuer_keys.py` lifecycle). It is NOT validated by an external operator (none exists). The asyncpg pool pattern (lifespan context manager) is standard FastAPI. The Starlette SessionMiddleware is the documented FastAPI session pattern. The SPA fallback (catch-all before StaticFiles) is the standard React-in-FastAPI pattern. The architecture is *conventional* — no novel combinations.
|
||||
- Confidence: 0.80
|
||||
- Decision: **G-009** — architecture is conventional (standard FastAPI + Postgres + React patterns), research-validated. No external operator exists (full autonomy). Accept. (0.80)
|
||||
|
||||
- **Q2: Integration surface — Postgres 16, asyncpg, Starlette SessionMiddleware, slowapi, argon2-cffi, react-router-dom. Risk of quiet cost doubling?**
|
||||
- Evidence: PLAN-v0.4:770-771 — 3 new pip deps (asyncpg, argon2-cffi, slowapi) + 1 new npm dep (react-router-dom). RESEARCH-v0.4 §new-deps.
|
||||
- Answer: 4 new dependencies. Each is a CVE vector + version-pin burden. asyncpg is the most consequential (new DB driver — connection pool lifecycle, statement cache, type coercion). slowapi is the youngest (maintenance risk — RESEARCH-v0.4 §2.5 notes "young lib, but works" at 0.70 confidence). argon2-cffi is mature (reference impl wrapper). react-router-dom@^7 is the standard React router (mature, but v7 is a major version — the `<BrowserRouter>` API is stable). The cost-doubling risk is low — these are all single-purpose, well-scoped deps. The *real* cost is the Postgres service (memory, disk, backup, migration runner) — but that is budgeted (6GB CT, pgdata/pgbackups volumes).
|
||||
- Confidence: 0.78
|
||||
- Decision: **G-010** — 4 new deps, all single-purpose and well-scoped. Cost-doubling risk is low. slowapi is the youngest dep — the plan documents a hand-rolled counter fallback (RESEARCH-v0.4 §2.5). Accept with the fallback documented. (0.78)
|
||||
|
||||
- **Q3: Is there an existing system being replaced? (VC issuer key store SQLite→Postgres — migration path for existing issued VCs?)**
|
||||
- Evidence: server/vc/issuer_keys.py (128 lines) — current SQLite-backed key store; D-051 — migration strategy; PLAN-v0.4 SLICE-04 — VC key migration slice; TASK-06-05 — R-VC-MIG-01 e2e test.
|
||||
- Answer: The VC issuer key store is being migrated (SQLite→Postgres). The v0.3 `issued_credentials` table remains in SQLite (no data migration — D-051 "no re-issuance"). The verification endpoint (TASK-04-04) will try Postgres for keys, fall back to SQLite for v0.3 credentials. This is a *two-store verification path* — a complexity that is on the critical path of R-VC-MIG-01.
|
||||
- Confidence: 0.75
|
||||
- Challenge: The two-store verification path (Postgres for keys, SQLite-fallback for v0.3 credentials) is a *hidden complexity*. Open Question #1 (PLAN-v0.4:742) defers this to EXECUTE: "the executor should choose the simpler approach." But this is not an implementation detail — it is an architectural decision that affects the verification endpoint's failure modes. If Postgres is down, can v0.3 credentials still verify? The plan says TASK-04-04 "try Postgres first, fall back to SQLite" but TASK-06-03 says "if pg_store is None, fall back to PraxisStore path (v0.3 compat)." These two fallback semantics are *consistent* but the plan does not make the consistency explicit.
|
||||
- Decision: **G-011 (MUST)** — The verification endpoint's two-store fallback semantics must be explicit in the plan, not deferred to EXECUTE. Rule: (a) if Postgres is available, use it for key lookup (both active + superseded keys); (b) if Postgres is available but the credential is not found in Postgres `issued_credentials`, fall back to SQLite `issued_credentials` (v0.3 credentials); (c) if Postgres is NOT available (no DSN), use the existing v0.3 SQLite path for both keys + credentials. This must be documented in TASK-04-04 and TASK-06-03 as a binding contract, not an open question. (0.75)
|
||||
|
||||
- **Q4: Technical debt inherited — v0.3's SQLite VC issuer keys, single hardcoded learner profile, no TLS in the LXC pilot.**
|
||||
- Evidence: db/store.py:29 — `HARDCODED_LEARNER_ID = "learner-1"`; server/__main__.py:46 — `HOST = _env("PRAXIS_HOST", "0.0.0.0")` (binds to all interfaces, not loopback); D-030 — no Traefik/TLS for pilot.
|
||||
- Answer: Three inherited debts:
|
||||
1. **SQLite VC issuer keys** — being migrated (D-051). This is v0.4's *job*, not inherited debt.
|
||||
2. **Single hardcoded learner profile** — `HARDCODED_LEARNER_ID = "learner-1"`. This is the *root cause* of the k-anon-at-pilot-scale problem (see signature probe #3). Not addressed in v0.4 (multi-learner-per-device is deferred). The aggregation pipeline groups by `learner_ref` but there is only one `learner_ref`. The dashboard will suppress everything.
|
||||
3. **No TLS in the LXC pilot** — D-030. This is the root cause of R-AUTH-01 (see signature probe #1). Not addressed in v0.4 (TLS deferred to a later milestone).
|
||||
- Confidence: 0.72
|
||||
- Decision: **G-012** — three inherited debts acknowledged: (1) SQLite VC keys → being migrated (v0.4's job); (2) single hardcoded learner → not addressed (k-anon suppresses all pilot data); (3) no TLS → not addressed (R-AUTH-01 config-driven punt). Debts #2 and #3 are accepted as pilot-scale constraints with documented mitigations. (0.72)
|

|
||||
|
||||
### Axis 4 — People, Skills, and Organization
|
||||
|
||||
- **Q1: Key-person dependency — which 2-3 personas, if absent, would v0.4 fail?**
|
||||
- Evidence: PERSONAS.md v0.4 roster — 6 active personas; PLAN-v0.4:79-86 + :419-426 — persona load distribution.
|
||||
- Answer: The 3 critical personas:
|
||||
1. **security-engineer** — owns VC key migration (R-VC-MIG-01, high severity) + auth stack (argon2id, cookies, rate limit). If absent, the highest-severity risk is unowned. 8 tasks in P1.
|
||||
2. **data-engineer** — owns Postgres schema + migration runner + PgStore + IssuerKeyStore protocol. If absent, the foundation (SLICE-01) is unowned. 8 tasks in P1 + 3 in P2.
|
||||
3. **backend-engineer** — owns asyncpg pool wiring + operator API (8 endpoints) + aggregation pipeline + SPA fallback + session_recorder extension. The largest task surface (16 tasks across P1+P2). If absent, the integration slices (SLICE-06, SLICE-10) have no owner.
|
||||
The lead-developer is coordination (not key-person — can be covered by backend-engineer). The frontend-engineer is P2-only (dashboard UI). The devops-engineer is P1-only (compose + backup + bootstrap). The key-person risk is concentrated in security + data + backend.
|
||||
- Confidence: 0.82
|
||||
- Decision: **G-013** — key-person dependency: security-engineer, data-engineer, backend-engineer. All 3 are critical-path. Under full autonomy with parallelization (max 5 concurrent), this is manageable. Accept. (0.82)
|
||||
|
||||
- **Q2: Are the 6 personas actually available?**
|
||||
- Evidence: config.json:22-27 — parallelization enabled, max 5 concurrent; PERSONAS.md — 6 active personas (lead, backend, frontend, data, security, devops). security-engineer + devops-engineer are NOT in config.json personas array (emergent — defined in PERSONAS.md, per PERSONAS.md:542).
|
||||
- Answer: All 6 are "available" in the sense that the CI agent spawns them on demand. The config.json `personas` array has only 4 (lead, backend, frontend, data); security + devops are emergent (PERSONAS.md). Territory enforcement is `warn` (config.json:51) — so emergent personas are not blocked. The max-concurrent-agents is 5, but 6 personas are active — one will be idle at peak. The P1 wave-2 has 3 parallel slices (SLICE-03, 04, 05) — 3 personas active (security, security, devops). The P2 wave-1 has 3 parallel slices (SLICE-07, 08, 09) — 3 personas (backend, backend, frontend). The 5-agent limit is not a binding constraint.
|
||||
- Confidence: 0.80
|
||||
- Decision: **G-014** — 6 personas available (4 in config + 2 emergent), max 5 concurrent. The 6>5 mismatch is not binding (peak parallelism is 3 slices). Accept. (0.80)
|
||||
|
||||
- **Q3: Product owner with authority?**
|
||||
- Evidence: config.json:13 — full autonomy; PROJECT.md:5.
|
||||
- Answer: CI is the product owner under full autonomy. This is the established model since v0.1. No committee. The grill is the pressure-test.
|
||||
- Confidence: 0.85
|
||||
- Decision: **G-015** — CI is the product owner with full authority (no change). (0.85)
|
||||
|
||||
- **Q4: Is the team building capability they don't have? (Postgres admin, k-anonymity, argon2id — all new to the project)**
|
||||
- Evidence: RESEARCH-v0.4 §1-7 — all 7 domains are new to the project (Postgres 16, asyncpg, argon2id, Starlette SessionMiddleware, slowapi, k-anonymity, React Router); PERSONAS.md v0.4 — data-engineer expands to Postgres, security-engineer expands to argon2id + slowapi.
|
||||
- Answer: Yes — the team is building capability it doesn't have. Postgres admin (migrations, pool, backup), k-anonymity (write-time suppression SQL), argon2id (OWASP params), signed cookies (Starlette SessionMiddleware), React Router (SPA fallback). All new. However: (a) this is a *pilot*, not a production system — learning-as-you-go is acceptable for prototypes per the grill's stance; (b) the research is thorough (OWASP fetched 2026-08-04, Postgres 16 docs verified, asyncpg pattern validated); (c) the highest-risk new capability (custom VC crypto) was already shipped in v0.3 with interop + rotation tests (verified in codebase: test_vc_interop.py, test_vc_key_rotation_drill.py). The v0.4 new capabilities are *conventional* (standard FastAPI + Postgres + React patterns), not novel.
|
||||
- Confidence: 0.75
|
||||
- Decision: **G-016** — team is building new capability (Postgres, auth, k-anon, React Router) but all are conventional patterns with thorough research. Accept for pilot. (0.75)

### Axis 5 — Timeline and Estimates
|
||||
|
||||
- **Q1: Was the 2-execution-phase structure set before or after the scope was understood?**
|
||||
- Evidence: ROADMAP.md:31-53 — P1/P2/P3 structure defined in ROADMAP (pre-PLAN); PLAN-v0.4:14-22 — phase split rationale refines the ROADMAP structure.
|
||||
- Answer: The ROADMAP defined P1 (operator foundation) + P2 (cohort dashboard) + P3 (review) *before* the PLAN. The PLAN refined the split (6 slices in P1, 4 in P2). The scope was understood at ROADMAP time (8 REQs from v0.3 grill deferral). The deadline (per-phase ship tags v0.1.7, v0.1.8, v0.1.9) was set in ROADMAP. This is *not* a reverse-engineered deadline — the phases are defined by scope (P1 = infra/auth, P2 = dashboard), not by a target date.
|
||||
- Confidence: 0.85
|
||||
- Decision: **G-017** — phase structure set after scope was understood (ROADMAP post-grill). Not reverse-engineered. (0.85)
|
||||
|
||||
- **Q2: Critical path — what single thing would push v0.4 by a phase?**
|
||||
- Evidence: PLAN-v0.4 wave dependency graphs (P1:60-75, P2:404-415); RESEARCH-v0.4 risks R-VC-MIG-01 (high), R-MT-01 (medium), R-DASH-03 (medium).
|
||||
- Answer: The critical path is P1 Wave 1 → Wave 2 → Wave 3 → P2 Wave 1 → Wave 2. The single thing that would push v0.4 by a phase:
|
||||
- **Most likely: SPA fallback breaking the voice UI (R-DASH-03/05).** The catch-all route (`@app.get("/{path:path}")`) before StaticFiles is a change to `server/__main__.py` — the *same file* that serves the voice loop. If the catch-all shadows StaticFiles asset serving (JS/CSS), the voice UI breaks. TASK-10-04 tests this (8 assertions), but if the test fails, the fix is non-trivial (route ordering in FastAPI is subtle). This would push P2 by a wave.
|
||||
- **Less likely: VC key migration (R-VC-MIG-01).** The e2e test (TASK-06-05) is thorough, but if the v0.3 public key fails to verify against the Postgres store (e.g., key_id mismatch, encoding issue), the migration is blocked. The mitigation (archive before activate) is correct, but the *test* is the proof.
|
||||
- **Least likely: Postgres resource contention (R-MT-01).** 6GB CT has ~50% margin. The nightly jobs are at 03:00 CT. This is a measurement issue, not a design issue.
|
||||
- Confidence: 0.75
|
||||
- Decision: **G-018** — critical-path risk: SPA fallback breaking voice UI (R-DASH-03). Mitigation: TASK-10-04 (8 assertions). If it fails, the fix is route ordering. Accept with the test as the gate. (0.75)
|
||||
|
||||
- **Q3: Are the 52 tasks evidence-based or pulled from a target?**
|
||||
- Evidence: PLAN-v0.4:764 — 52 tasks (29 P1 + 23 P2); GRILL-v0.3.md:29 — v0.3 had 70 tasks (originally) → shipped as ~40 after the grill split; ROADMAP.md:81 — v0.3 P1 shipped as v0.1.4.
|
||||
- Answer: v0.3 shipped ~40 tasks (post-grill split) successfully. v0.4 has 52 tasks across 2 phases (29 + 23). The task count is *analogous* to v0.3 (40 tasks → 52 tasks, +30%). The scope is comparable (v0.3 mastery+VC vs v0.4 operator tier). The tasks are bottom-up sized (each slice has 3-7 tasks with acceptance criteria). Not pulled from a target.
|
||||
- Confidence: 0.80
|
||||
- Decision: **G-019** — 52 tasks is evidence-based (analogous to v0.3's 40, bottom-up sized). Accept. (0.80)
|
||||
|
||||
- **Q4: Definition of done?**
|
||||
- Evidence: PLAN-v0.4 — per-slice acceptance criteria; ROADMAP.md:16-20 — per-phase ship + verify; config.json:28-33 — verification automated.
|
||||
- Answer: Definition of done = per-slice acceptance criteria (each task has "Acceptance criteria") + per-phase ship (v0.1.7, v0.1.8) + verify stage. The grill is the P0 definition of done. This is the established pattern since v0.2.
|
||||
- Confidence: 0.85
|
||||
- Decision: **G-020** — definition of done is per-slice acceptance criteria + per-phase ship + verify. Established pattern. Accept. (0.85)
|
||||

|
||||
|
||||
### Axis 6 — Budget and Financial Realism
|
||||
|
||||
- **Q1: Budget spent vs remaining?**
|
||||
- Evidence: git log — v0.1 (foundation) + v0.2 (LXC deploy) + v0.3 (mastery+VC) shipped; v0.4 is the 4th milestone. No token budget tracked in `.ciagent/` (token cost is implicit in the CI agent's operation).
|
||||
- Answer: No explicit token budget. The project has shipped 3 milestones (v0.1-v0.3) — the token cost is sunk. v0.4 is the 4th. Under full autonomy, the "budget" is the CI agent's operational cost (tokens + compute). No budget contingency is tracked. This is a pilot — the budget is "whatever it costs to ship the milestones." Not a financial-realism concern at pilot scale.
|
||||
- Confidence: 0.75
|
||||
- Decision: **G-021** — no explicit token budget (pilot, full autonomy). v0.4 is the 4th milestone. Accept the implicit budget model. (0.75)
|
||||
|
||||
- **Q2: Predictable cost drivers not in original budget? (Postgres 16 in LXC = CT memory bump 4GB→6GB; new deps = larger Docker image; backup storage)**
|
||||
- Evidence: RESEARCH-v0.4 §1.1 — CT memory 4GB→6GB (confirmed); PLAN-v0.4 TASK-02-02 — CT bump; TASK-02-03 — backup volume; ARCHITECTURE.md:737 — v0.4 CT sizing.
|
||||
- Answer: Three cost drivers:
|
||||
1. **CT memory 4GB→6GB** — budgeted (TASK-02-02). The 6GB figure has ~50% margin (RESEARCH-v0.4 §1.1).
|
||||
2. **Larger Docker image** — asyncpg + argon2-cffi + slowapi add ~10-20MB to the image. Negligible.
|
||||
3. **Backup storage** — pgbackups named volume, 7-day retention, pg_dump -Fc (compressed). At v0.4 scale (<100 learners), each dump is <1MB. 7 files = <7MB. Negligible.
|
||||
- Confidence: 0.85
|
||||
- Decision: **G-022** — cost drivers are budgeted (6GB CT, backup volume). Image size + backup storage are negligible at pilot scale. Accept. (0.85)
|
||||
|
||||
- **Q3: Burn rate — how long until v0.4 ships at current pace?**
|
||||
- Evidence: git log — v0.3 took ~1 day (commits from 2026-08-03 to 2026-08-04); v0.2 similar. v0.4 has 52 tasks vs v0.3's 40.
|
||||
- Answer: v0.3 shipped in ~1 day. v0.4 is +30% larger (52 vs 40 tasks). Expected: ~1.3 days of CI agent time. The burn rate is the CI agent's token consumption — not tracked, but the pace is established (3 milestones in ~3 days).
|
||||
- Confidence: 0.75
|
||||
- Decision: **G-023** — burn rate: ~1.3 days estimated (analogous to v0.3). Accept. (0.75)
|
||||
|
||||
- **Q4: Budget contingent on anything?**
|
||||
- Evidence: config.json:13 — full autonomy; config.json:39-43 — git auto-commit, no auto-push.
|
||||
- Answer: No. Full autonomy, no external approval, no contingent funding. The only contingency is the `escalation_hooks` (deploy, delete_data, merge_to_main) — none of which apply to v0.4 P0/P1/P2 execution (merge_to_main is P3, which is the final ship).
|
||||
- Confidence: 0.90
|
||||
- Decision: **G-024** — no budget contingency (full autonomy, no external approval). Accept. (0.90)
|
||||

|
||||
|
||||
### Axis 7 — Risks, Assumptions, and Dependencies
|
||||
|
||||
- **Q1: Top 3 assumptions v0.4 rests on — evidence for each?**
|
||||
- Evidence: RESEARCH-v0.4 risks table (R-MT-01, R-AUTH-01, R-DASH-01).
|
||||
- Answer:
|
||||
1. **Postgres-in-LXC won't destabilize the learner service (R-MT-01).** Evidence: RESEARCH-v0.4 §1.1 — Postgres idle ~400MB, praxis ~500MB, 6GB CT has ~50% margin. Postgres queries are off the voice path (operator endpoints + nightly aggregation only). The nightly jobs are at 03:00 CT. **Confidence: 0.75** — the memory math is sound but the *disk I/O contention during pg_dump* is unmeasured. The mitigation (03:00 CT) is a scheduling assumption, not a measurement.
|
||||
2. **k-anonymity ≥ 10 is sufficient privacy (D-034).** Evidence: RESEARCH-v0.4 §3.1 — "k=10 is the textbook suppression pattern." Differencing attacks blocked by pre-defined 2-D views. **Confidence: 0.70** — k=10 is the conventional minimum, but at pilot scale (1 learner) k-anon suppresses *everything*, which is privacy-correct but value-destroying. The assumption holds for privacy; it does not hold for dashboard utility at pilot scale.
|
||||
3. **Signed stateless cookies are secure without TLS in the pilot (R-AUTH-01).** Evidence: RESEARCH-v0.4 §2.4 — config-driven `PRAXIS_COOKIE_SECURE`, defense-in-depth (cohort dashboard reads only k-anonymized aggregates). **Confidence: 0.65** — this is the *signature question* (see probe #1 below). The config-driven flag is a punt; the real mitigation is the k-anon defense-in-depth.
|
||||
- Confidence: 0.72
|
||||
- Decision: **G-025** — 3 core assumptions: Postgres contention (0.75, unmeasured disk I/O), k-anon sufficiency (0.70, privacy-correct but value-destroying at pilot scale), cookie-without-TLS (0.65, config-driven punt with k-anon defense-in-depth). All accepted as pilot-scale constraints. (0.72)
|
||||
|
||||
- **Q2: Dependencies outside the team?**
|
||||
- Evidence: config.json:13 — full autonomy; PROJECT.md:5.
|
||||
- Answer: None. Single project, full autonomy. No external departments, vendors, regulators, or customers. The only "external" dependency is the Proxmox cluster (v0.2 deployment) + Ollama Cloud + Deepgram + Cartesia (voice services) — all carried forward from v0.1-v0.2.
|
||||
- Confidence: 0.90
|
||||
- Decision: **G-026** — no external dependencies (full autonomy). Accept. (0.90)
|
||||
|
||||
- **Q3: Single risk that kills v0.4? (R-VC-MIG-01 — losing the v0.3 public key breaks all issued VCs. Mitigation: archive before activate. Is this enough?)**
|
||||
- Evidence: RESEARCH-v0.4 R-VC-MIG-01 (high severity, 0.85 confidence); PLAN-v0.4 SLICE-04 TASK-04-03 (migration script archives v0.3 public key BEFORE activating new key); TASK-06-05 (e2e test verifies v0.3 VC against Postgres store).
|
||||
- Answer: R-VC-MIG-01 is the single project-killing risk. If the v0.3 public key is lost, all v0.3 VCs break. The mitigation is *correct*: archive before activate (TASK-04-03 step 2 before step 3). The e2e test (TASK-06-05) verifies a v0.3 VC against the Postgres store with the archived superseded key. This is the *right* test. The risk is mitigated.
|
||||
- However, there is a *subtle* gap: the migration script (TASK-04-03) reads the v0.3 public key from SQLite. If the SQLite `issuer_keys` table is empty (e.g., the v0.3 pilot never issued a VC → no key was ever generated), the migration script's behavior is undefined. The script should handle "no v0.3 key exists" gracefully (skip the archive step, just generate a fresh v0.4 key). The plan says "Idempotent: if Postgres already has an active key, skip" but does not say "if SQLite has no active key, skip the archive."
|
||||
- Confidence: 0.80
|
||||
- Challenge: The migration script's behavior when SQLite has no v0.3 active key is unspecified. This is an edge case (the pilot may never have issued a VC), but it is the *first-boot* path for most deployments.
|
||||
- Decision: **G-027 (MUST)** — TASK-04-03 must explicitly handle the "no v0.3 active key in SQLite" case: if `get_active_signing_key_row()` on SQLite returns None, skip the archive step and only generate the fresh v0.4 keypair. Document this as a first-boot path. The e2e test (TASK-06-05) should include a "no v0.3 key" scenario. (0.80)
|
||||
|
||||
- **Q4: Pre-mortem — "It's 90 days from now and v0.4 failed. Why?"**
|
||||
- Evidence: RESEARCH-v0.4 risks; PLAN-v0.4 risk matrix.
|
||||
- Answer: The most likely failure modes (in order):
|
||||
1. **SPA fallback broke the voice UI (R-DASH-03/05).** The catch-all route shadowed StaticFiles asset serving. The voice UI loaded but JS/CSS 404'd. The operator dashboard worked but the learner product regressed. This is the *highest-blast-radius* failure — it breaks the v0.1-v0.3 learner surface, not just the v0.4 operator surface.
|
||||
2. **Postgres contention degraded the voice loop latency (R-MT-01).** The nightly pg_dump + aggregation job at 03:00 CT caused disk I/O contention that spiked the voice loop latency >600ms. This was not caught because the latency test does not run with Postgres loaded.
|
||||
3. **The secure-cookie+no-TLS tension was unresolved (R-AUTH-01).** The config-driven flag was set to `false` for the pilot, the operator cookie was sniffed over HTTP on the vmbr0 bridge, and the grill should have caught that the config flag is a punt, not a fix.
|
||||
4. **The k-anon dashboard showed nothing at pilot scale.** The operator logged in, saw "— (<10 learners)" for every cell, and concluded the dashboard was broken. The grill should have caught that the dashboard's validation path is test-seeded data, not pilot traffic.
|
||||
- Confidence: 0.78
|
||||
- Decision: **G-028** — pre-mortem top-4 failure modes: SPA fallback regression (highest blast radius), Postgres contention (unmeasured), R-AUTH-01 punt, k-anon-empty-dashboard. All four are addressed in this grill's binding decisions. (0.78)
|
||||
|
||||

|
||||
|
||||
### Axis 8 — Governance, Decision-Making, and Communication
|
||||
|
||||
- **Q1: Decision-maker when two personas disagree?**
|
||||
- Evidence: config.json:52-54 — lead-developer is the first persona; PERSONAS.md v0.4 — lead-developer "Coordinates task decomposition... resolves conflicts."
|
||||
- Answer: lead-developer is the decision-maker. This is the established pattern since v0.1.
|
||||
- Confidence: 0.85
|
||||
- Decision: **G-029** — lead-developer is the conflict resolver. Accept. (0.85)
|
||||
|
||||
- **Q2: Governance cadence?**
|
||||
- Evidence: ROADMAP.md:19 — pipeline stages SPECIFY → CLARIFY → RESEARCH → PLAN → GRILL → SHIP; config.json:105-108 — per-phase ship.
|
||||
- Answer: Per-phase ship + verify + grill at P0. This is the established cadence. The grill is the crisis-cadence (this document).
|
||||
- Confidence: 0.85
|
||||
- Decision: **G-030** — governance cadence: per-phase ship + verify + grill. Accept. (0.85)
|
||||
|
||||
- **Q3: What's omitted from status reports? (R-AUTH-01 is the smell)**
|
||||
- Evidence: RESEARCH-v0.4 §2.4 — R-AUTH-01 resolution documented as "the grill must sign off"; PLAN-v0.4:718 — risk matrix lists R-AUTH-01 with "grill must sign off."
|
||||
- Answer: The smell is R-AUTH-01. The research *acknowledges* the tension but frames the config-driven flag as a resolution. The v0.3 grill (Axis 4 MUST #2) explicitly rejected this approach: "Do not ship `PRAXIS_COOKIE_SECURE=false` as default — use TLS or loopback-binding." The v0.4 plan ships `PRAXIS_COOKIE_SECURE` defaulting to `true` with `false` for HTTP pilot — which is *option (b)* from the v0.3 grill (accept the pilot risk + document) wrapped in a config flag. The v0.3 grill rejected option (b). The v0.4 plan re-litigates this.
|
||||
- The *real* mitigation — the one the v0.3 grill did not consider — is the k-anon defense-in-depth: the cohort dashboard reads only k-anonymized aggregates, so even a sniffed cookie leaks no PII. This is the *actual* answer to R-AUTH-01, not the config flag.
|
||||
- Confidence: 0.70
|
||||
- Challenge: The plan's R-AUTH-01 resolution re-litigates a v0.3 grill MUST. The config-driven flag is a punt. The real mitigation (k-anon defense-in-depth) is buried in the research, not elevated.
|
||||
- Decision: **G-031 (MUST)** — R-AUTH-01 resolution must be reframed: the *primary* mitigation is the k-anon defense-in-depth (cohort dashboard reads only k-anonymized aggregates → sniffed cookie leaks no PII). The config-driven `PRAXIS_COOKIE_SECURE` flag is the *secondary* mitigation (operational convenience for when TLS arrives). The plan must document this ordering explicitly in TASK-03-02 and the GRILL-v0.4 ship notes. The v0.3 grill's "use TLS or loopback-binding" MUST is *not* satisfied — but the k-anon defense-in-depth is a *new* mitigation that the v0.3 grill did not evaluate (the v0.3 cohort dashboard was deferred). This grill accepts the k-anon defense-in-depth as the primary R-AUTH-01 resolution for v0.4, *overriding* the v0.3 grill's MUST #2 for the operator-tier surface only. (0.70)
|
||||
|
||||
- **Q4: Stop-the-project trigger?**
|
||||
- Evidence: config.json:13 — full autonomy; config.json:15 — `escalation_hooks: ["deploy", "delete_data", "merge_to_main"]`.
|
||||
- Answer: No human stop trigger (full autonomy). The CI agent can escalate (escalation_hooks) but cannot self-stop. The grill is the stop-the-project mechanism — if the verdict were "Rethink" or "Escalate," the project would stop. This grill's verdict is "Proceed-with-conditions," so the project proceeds.
|
||||
- Confidence: 0.80
|
||||
- Decision: **G-032** — no human stop trigger (full autonomy). The grill is the stop mechanism. This grill = proceed with conditions. (0.80)
|
||||

|
||||
|
||||
### Axis 9 — Change, Adoption, and Operational Readiness
|
||||
|
||||
- **Q1: Who will use the cohort dashboard, and what's in it for them?**
|
||||
- Evidence: D-052 — operator bootstrap is env-provided (not a real user); PROJECT.md:53 — "for training operators"; PERSONAS.md — no operator persona (operators are external to the CI agent).
|
||||
- Answer: The *first operator* is env-provided (D-052 — `PRAXIS_BOOTSTRAP_OPERATOR_USER/PASS`). There is no real operator user in the pilot. The dashboard is a *capability demonstration*, not a tool for a named user. "What's in it for them" = visibility into cohort progression, but at pilot scale (1 learner) the dashboard shows nothing (k-anon suppresses all cells). The dashboard's value is *architectural* (proving the operator tier works), not *operational* (no operator uses it yet).
|
||||
- Confidence: 0.65
|
||||
- Challenge: The dashboard has no real user at pilot scale. This is a *placeholder deliverable* — the capability exists, but no one uses it. The "we'll train them" answer does not apply (there is no "them").
|
||||
- Decision: **G-033** — the cohort dashboard's first user is env-provided (D-052), not a real operator. At pilot scale (1 learner), the dashboard shows no data (k-anon). The dashboard is a *capability demonstration* for v0.5+ (when multi-learner data exists). Document this in the ship notes — v0.4 delivers the operator tier *capability*, not operator *value*. (0.65)
|
||||
|
||||
- **Q2: Is the operations team involved now or handed a finished product?**
|
||||
- Evidence: PERSONAS.md v0.4 — devops-engineer is active in P1 (docker-compose Postgres + CT bump + backup + bootstrap); PLAN-v0.4 SLICE-02 — devops tasks.
|
||||
- Answer: devops-engineer is involved in P1 (SLICE-02 — .env.example, CT bump, backup script, bootstrap CLI). This is *good* — the operations surface is built by the operations persona, not handed off. The backup strategy (TASK-02-03) is devops-owned. The bootstrap CLI (SLICE-05) is devops-owned. The operations team is involved *now*.
|
||||
- Confidence: 0.85
|
||||
- Decision: **G-034** — devops-engineer is involved in P1 (operations surface built by operations persona). Accept. (0.85)
|
||||
|
||||
- **Q3: Rollback plan if v0.4 goes wrong?**
|
||||
- Evidence: PLAN-v0.4 — per-phase ship (v0.1.7, v0.1.8, v0.1.9) + git rollback; config.json:42-43 — branching_strategy: phase.
|
||||
- Answer: Per-phase git rollback (revert the patch tag). But:
|
||||
- **P1 rollback (v0.1.7)**: Reverting P1 removes the Postgres service + auth. The VC key migration is *irreversible* — once the v0.3 public key is archived as superseded in Postgres and the fresh v0.4 key is active, reverting to v0.3 SQLite keys requires re-pointing the verification endpoint back to SQLite. The plan's fallback (TASK-06-03 — "if pg_store is None, fall back to PraxisStore path") makes this *possible* (set `PRAXIS_PG_DSN` to empty → server falls back to SQLite). This is a *soft* rollback — the Postgres data persists but is unused.
|
||||
- **P2 rollback (v0.1.8)**: Reverting P2 removes the aggregation pipeline + dashboard. The SPA fallback catch-all route removal is *clean* (revert the route). The React Router addition is *clean* (revert package.json + App.tsx). The aggregation hook in session_recorder.py is *clean* (revert the chained task). P2 rollback is clean.
|
||||
- **Postgres data migration is hard to roll back** — but the plan does not migrate data (v0.3 credentials stay in SQLite; v0.4 credentials go to Postgres). The VC key *archival* is irreversible (the v0.3 public key is copied to Postgres as superseded), but this is *additive* — the v0.3 SQLite key still exists. Reverting to v0.3 means ignoring the Postgres copy.
|
||||
- Confidence: 0.75
|
||||
- Decision: **G-035** — rollback is per-phase git revert. P1 rollback is *soft* (set `PRAXIS_PG_DSN` to empty → server falls back to SQLite). P2 rollback is *clean* (revert routes + package.json + session_recorder hook). VC key archival is additive (v0.3 SQLite key persists). Accept. (0.75)
|
||||
|
||||
- **Q4: Has anyone validated the success criteria with the people who will judge v0.4 successful?**
|
||||
- Evidence: config.json:13 — full autonomy; config.json:28-33 — verification automated.
|
||||
- Answer: No human judge (full autonomy). The CI agent is the judge. The success criteria = 8/8 REQ-IDs covered + per-slice acceptance criteria + verify stage. This is the established pattern.
|
||||
- Confidence: 0.80
|
||||
- Decision: **G-036** — CI is the judge (full autonomy). Success = 8/8 REQ coverage + acceptance criteria + verify. Accept. (0.80)

### Meta — Closing Review
|
||||
|
||||
- **Q1: If you were the auditor, what would you flag?**
|
||||
- Evidence: all axes above.
|
||||
- Answer: Three flags:
|
||||
1. **R-AUTH-01 re-litigates a v0.3 grill MUST.** The config-driven flag is a punt. The k-anon defense-in-depth is the real mitigation but is not elevated. (G-031)
|
||||
2. **The k-anon dashboard shows nothing at pilot scale.** The dashboard's validation path is test-seeded data, not pilot traffic. This is a placeholder deliverable. (G-033)
|
||||
3. **Backup verification is a hidden requirement.** A nightly pg_dump that is never restored is theater. (G-008)
|
||||
- Confidence: 0.78
|
||||
- Decision: **G-037** — auditor flags: R-AUTH-01 re-litigation, k-anon-empty-dashboard, backup-verification gap. All addressed in binding decisions. (0.78)
|
||||
|
||||
- **Q2: What is v0.4 NOT doing that it should?**
|
||||
- Evidence: PLAN-v0.4 open questions (742-754); RESEARCH-v0.4.
|
||||
- Answer:
|
||||
1. **Backup restore drill** — not tasked (G-008).
|
||||
2. **Latency test with Postgres loaded** — the voice loop latency test (TASK-06-04) checks that Postgres presence doesn't destabilize the learner service, but it does not run the voice loop *under load* with Postgres running the nightly job. The R-MT-01 disk I/O contention is unmeasured.
|
||||
3. **Operator deactivation** — no CLI to set `is_active=false`. Minor (SQL workaround), but a gap in the operator lifecycle.
|
||||
4. **Differencing-attack test for k-anon** — the v0.3 grill (Axis 7 FIX #2) asked for a differencing-attack test. The v0.4 plan (TASK-07-05) tests k-anon threshold (9 vs 10) but does NOT test that two adjacent 7-day windows cannot re-identify a single learner. This is a v0.3 grill FIX that is not explicitly carried forward.
|
||||
- Confidence: 0.75
|
||||
- Decision: **G-038 (MUST)** — Add a differencing-attack test to TASK-07-05 or TASK-10-03: seed 10 learners in window A, 9 in window B (1 dropped), verify the API does not allow a query that isolates the dropped learner. This is a v0.3 grill FIX (Axis 7 #2) that must be carried forward. (0.75)
|
||||
|
||||
- **Q3: Simplest possible v0.4 that delivers 80% of the value?**
|
||||
- Evidence: D-053 — 3 dashboard views; PLAN-v0.4 SLICE-08, SLICE-09.
|
||||
- Answer: The simplest v0.4 = auth + Postgres + *single* dashboard view (practice volume only) + VC key migration. The mastery-progression and failure-patterns views are +20% value but +30% effort (2 more endpoints + 2 more React components + 2 more aggregation metrics). However: D-053 is a CLARIFY decision (0.80 confidence) that names 3 views — cutting to 1 would re-litigate a settled decision. The 3 views are not over-scoped *relative to the decision*. The simpler answer is: v0.4 is already the simplest version (8 REQs, no RBAC, no DP, no learner auth, single operator). Cutting further would break the v0.3 grill's deferred obligation.
|
||||
- Confidence: 0.75
|
||||
- Decision: **G-039** — v0.4 is already the simplest version (8 REQs, single operator role, k-anon not DP). The 3-view dashboard is D-053 (settled). Further cuts would break the v0.3 grill obligation. Accept the scope. (0.75)
|
||||
|
||||
- **Q4: What would have to be true for v0.4 to succeed in the next 90 days, and is it true today?**
|
||||
- Evidence: all axes.
|
||||
- Answer: For v0.4 to succeed:
|
||||
1. **The SPA fallback must not break the voice UI.** Is it true today? No — it is untested (TASK-10-04 is the test). Will be true after P2.
|
||||
2. **The VC key migration must preserve v0.3 VC verification.** Is it true today? No — it is untested (TASK-06-05 is the test). Will be true after P1.
|
||||
3. **Postgres must not destabilize the learner service.** Is it true today? Partially — the memory math is sound (6GB CT), but disk I/O contention is unmeasured. Will be true after P1 (with the 03:00 CT mitigation).
|
||||
4. **The auth stack must be secure enough for a pilot.** Is it true today? Partially — R-AUTH-01 is a punt with k-anon defense-in-depth. Will be true after G-031 reframes the mitigation.
|
||||
5. **The dashboard must show *something* useful.** Is it true today? No — at pilot scale (1 learner), k-anon suppresses everything. Will be true only with test-seeded data (≥10 mock learners).
|
||||
- Confidence: 0.72
|
||||
- Decision: **G-040** — 5 success conditions: SPA fallback (untested), VC migration (untested), Postgres stability (partially), auth security (partially, G-031), dashboard utility (only with test-seeded data). All addressable in P1/P2. Accept with binding decisions. (0.72)

### v0.4-Specific Probes (Signature Questions)
|
||||
|
||||
#### Probe 1 — R-AUTH-01 (Secure cookie + no-TLS): Resolution
|
||||
|
||||
**Question:** D-030 said no Traefik/TLS for the pilot. D-041 requires `Secure` cookie attribute. `Secure` requires HTTPS. The research proposes `PRAXIS_COOKIE_SECURE` config-driven (default true, false for HTTP pilot). Is this a real resolution or a punt? What's the actual risk of running auth over HTTP in the LXC pilot? Is the cohort dashboard worth a TLS regression?
|
||||
|
||||
**Evidence:**
|
||||
- D-030 (PROJECT.md:160) — "vmbr0 DHCP only (pilot, no vmbr1, no Traefik proxy)."
|
||||
- D-041 (PROJECT.md:171) — "Cookie: httpOnly, secure, SameSite=Strict, 8h expiry."
|
||||
- RESEARCH-v0.4 §2.4 — config-driven flag, "cohort dashboard reads only k-anonymized aggregates → even a cookie sniffed over HTTP leaks no PII."
|
||||
- GRILL-v0.3.md Axis 4 MUST #2 — "Do not ship `PRAXIS_COOKIE_SECURE=false` as default — use TLS or loopback-binding."
|
||||
- server/__main__.py:46 — `HOST = _env("PRAXIS_HOST", "0.0.0.0")` (binds to all interfaces).
|
||||
|
||||
**Analysis:**
|
||||
The v0.3 grill explicitly rejected shipping `PRAXIS_COOKIE_SECURE=false` as a default. The v0.4 plan ships `PRAXIS_COOKIE_SECURE` defaulting to `true` with `false` for HTTP pilot — which is *option (b)* from the v0.3 grill (accept the pilot risk + document) wrapped in a config flag. This *re-litigates* the v0.3 grill MUST.
|
||||
|
||||
However, the v0.3 grill evaluated R-AUTH-01 *before* the cohort dashboard was scoped. The v0.3 grill's concern was "a cleartext cookie on a shared bridge is a MUST-FIX" — but the v0.3 grill did not know that the cohort dashboard would read *only k-anonymized aggregates*. The v0.4 research introduces a *new* mitigation: **the k-anon defense-in-depth**. A sniffed cookie gives the attacker access to `/api/operator/*`, which returns only k-anonymized cohort data (no PII) + the VC issuance log (credentials are public per D-043). The *worst* an attacker can do with a sniffed operator cookie is:
|
||||
- Read k-anonymized cohort aggregates (no PII — D-034).
|
||||
- Read the VC issuance log (credentials are public — D-043).
|
||||
- Revoke a VC (POST `/api/operator/credentials/{id}/revoke`) — this is a *denial-of-service* on a credential, but the credential is formative (v0.3 grill Axis 4 MUST #1) and the revocation is reversible (operator can re-issue).
|
||||
|
||||
The *actual* risk of running auth over HTTP in the LXC pilot is: an attacker on the vmbr0 bridge can sniff the operator cookie and revoke a formative credential. This is a *low-severity* risk for a pilot. The v0.3 grill's "MUST-FIX" was correct *for a high-stakes credential* — but the v0.3 grill itself downgraded the credential to formative (MUST #1), which *also* downgrades the R-AUTH-01 severity.
|
||||
|
||||
**Resolution:**
|
||||
The config-driven `PRAXIS_COOKIE_SECURE` flag is a *punt* — it does not fix the underlying tension. The *real* resolution is the k-anon defense-in-depth + the formative credential tier. The v0.3 grill's MUST #2 ("use TLS or loopback-binding") is *overridden* for the v0.4 operator-tier surface because:
|
||||
1. The cohort dashboard reads only k-anonymized aggregates (no PII leak from a sniffed cookie).
|
||||
2. The VC credential is formative (low-stakes — revocation is a reversible DoS, not a forgery).
|
||||
3. The pilot binds to vmbr0 DHCP (shared bridge) — but the pilot has 1 learner and 1 env-provided operator. The attack surface is theoretical.
|
||||
|
||||
**Binding Decision G-031 (MUST)** — R-AUTH-01 resolution: the *primary* mitigation is the k-anon defense-in-depth (sniffed cookie → no PII). The config-driven flag is *secondary* (operational convenience). The plan must document this ordering. The v0.3 grill's MUST #2 is overridden for v0.4 *only* because the v0.3 grill's own formative-credential decision (MUST #1) downgraded the R-AUTH-01 severity. This is a *consistent* override — the v0.3 grill's two MUSTs interact, and the formative tier + k-anon defense-in-depth together resolve the tension that either alone does not.
|
||||
|
||||
**Confidence: 0.70** — the resolution is sound but re-litigates a prior grill MUST. The override is justified by the *interaction* of two v0.3 grill decisions (formative tier + k-anon), not by a single new fact.
|
||||

|
||||
|
||||
#### Probe 2 — R-VC-MIG-01 (VC key migration): Is "archive before activate" enough?
|
||||
|
||||
**Question:** v0.3 issued VCs are in the field (hypothetically). v0.4 migrates the issuer key to Postgres. If the v0.3 public key is lost, all v0.3 VCs break. The plan says "archive before activate." Is that enough? Is there a test that verifies a v0.3 VC against the archived key after migration?
|
||||
|
||||
**Evidence:**
|
||||
- PLAN-v0.4 TASK-04-03 — migration script: step 2 (archive v0.3 public key as superseded) BEFORE step 3 (generate fresh v0.4 key).
|
||||
- PLAN-v0.4 TASK-06-05 — e2e test: "v0.3 VC verifies against Postgres store with archived superseded key (R-VC-MIG-01 explicitly verified)."
|
||||
- server/vc/issuer_keys.py:102-109 — `get_public_key_for_verification` queries by `key_id` (not status) — the fallback to superseded keys is implicit.
|
||||
- RESEARCH-v0.4 §5.3 — "No code change needed in the verification flow — only the store backing changes."
|
||||
|
||||
**Analysis:**
|
||||
"Archive before activate" is the *correct* ordering — if the migration fails between step 2 and step 3, the v0.3 key is archived but no v0.4 key is active. The verification endpoint would find the v0.3 key (superseded) and verify v0.3 VCs. New VCs cannot be issued (no active key) until the migration is re-run. This is a *safe failure mode*.
|
||||
|
||||
The e2e test (TASK-06-05) is thorough: it seeds a v0.3 VC, runs the migration, verifies the v0.3 VC against the Postgres store, issues a v0.4 VC, verifies it, tampers with the v0.3 VC (verification fails), and re-runs the migration (idempotent). This covers R-VC-MIG-01.
|
||||
|
||||
**Gap (G-027):** The migration script's behavior when SQLite has *no* v0.3 active key (the pilot never issued a VC) is unspecified. This is the *first-boot* path for most deployments. Must be handled.
|
||||
|
||||
**Verdict:** "Archive before activate" is enough *with* the e2e test (TASK-06-05) as the proof. The gap (no v0.3 key) is a binding decision (G-027). **Confidence: 0.80.**
|
||||

|
||||
#### Probe 3 — k-anonymity at pilot scale: Dashboard that shows nothing?
|
||||
|
||||
**Question:** v0.1-v0.3 used `HARDCODED_LEARNER_ID = "learner-1"` — a single learner. k-anonymity ≥ 10 will suppress EVERY cell in the cohort dashboard. The dashboard will show "— (<10 learners)" for everything. Is v0.4 building a dashboard that can't show any data until there are 10+ learners? Is that a real deliverable or a placeholder? What test data seeds ≥10 mock learners?
|
||||
|
||||
**Evidence:**
|
||||
- db/store.py:29 — `HARDCODED_LEARNER_ID = "learner-1"` (confirmed — single learner).
|
||||
- D-034 (PROJECT.md:164) — "k-anonymity ≥ 10."
|
||||
- REQ-NFR-DASH-01 — "cells with < 10 learners are suppressed."
|
||||
- PLAN-v0.4 Open Question #3 (line 746) — "For v0.4 (single learner), k-anonymity will suppress everything (1 < 10). This is expected at pilot scale (R-DASH-01). The executor should seed test data with ≥10 mock learners to verify the non-suppressed path."
|
||||
- PLAN-v0.4 TASK-10-03 — P2 integration test seeds 15 mock sessions (12 distinct learners) for the non-suppressed path + 5 sessions (5 learners) for the suppressed path.
|
||||
|
||||
**Analysis:**
|
||||
At pilot scale (1 learner), the dashboard shows "— (<10 learners)" for every cell. This is *privacy-correct* (k-anon is working) but *value-destroying* (the dashboard is useless). The plan acknowledges this (Open Question #3) and the validation path is *test-seeded data* (TASK-10-03 seeds 12 + 5 mock learners). The dashboard is a *capability demonstration*, not an operational tool — at pilot scale, no operator uses it (G-033).
|
||||
|
||||
This is a *real deliverable* in the sense that the *capability* exists (Postgres + aggregation + k-anon + auth + UI), but it is a *placeholder* in the sense that it cannot show real data until multi-learner-per-device is implemented (deferred). The v0.4 milestone delivers the *plumbing*, not the *value*.
|
||||
|
||||
**Verdict:** The dashboard is a placeholder deliverable at pilot scale. The validation path is test-seeded data (TASK-10-03), not pilot traffic. This must be documented in the ship notes (G-033). The k-anon suppression is *correct behavior* — the dashboard is working as designed. The issue is that the design is correct for a *cohort* but the pilot has *one learner*. **Confidence: 0.75.**
|

|
||||
|
||||
#### Probe 4 — Postgres-in-LXC resource contention (R-MT-01): Voice loop latency?
|
||||
|
||||
**Question:** Adding Postgres to the LXC CT bumps memory 4GB→6GB. The learner-facing voice loop has a <600ms latency budget (C-8). Will Postgres idle I/O + the aggregation pipeline degrade the voice loop? Is there a latency test that runs with Postgres loaded?
|
||||
|
||||
**Evidence:**
|
||||
- RESEARCH-v0.4 §1.1 — Postgres idle ~400MB, praxis ~500MB, 6GB CT has ~50% margin. "Postgres queries are off the voice path (operator endpoints + nightly aggregation only)."
|
||||
- R-MT-01 — "disk I/O contention during nightly pg_dump + aggregation." Mitigation: 03:00 CT.
|
||||
- PLAN-v0.4 TASK-06-04 — "Test that learner voice loop (`/health`, `/pipecat/webrtc`) is unaffected by auth (REQ-NFR-MT-01 — Postgres + learner service coexist)."
|
||||
- C-8 — latency budget < 600ms.
|
||||
|
||||
**Analysis:**
|
||||
The memory math is sound (6GB CT, ~1.3GB runtime, ~4.7GB headroom). The *voice loop* (WebRTC → Pipecat → ASR → LLM → TTS) does not touch Postgres — it uses SQLite for learner state (D-007 preserved) and the voice services (Deepgram, Cartesia, Ollama Cloud). Postgres is used only by operator endpoints + nightly aggregation. The *risk* is disk I/O contention during the nightly pg_dump + aggregation job (03:00 CT).
|
||||
|
||||
TASK-06-04 tests that Postgres presence doesn't destabilize the learner service — but it tests *coexistence* (health check passes, WebRTC offer accepted), not *latency under load*. The plan does NOT include a latency test that runs the voice loop *while Postgres is executing the nightly job*. The R-MT-01 mitigation (03:00 CT scheduling) is a *scheduling* assumption, not a *measurement*.
|
||||
|
||||
**Verdict:** The memory contention is well-mitigated (6GB CT). The disk I/O contention is *unmeasured* — the 03:00 CT mitigation is reasonable (low learner activity) but not proven. The voice loop does not touch Postgres, so the *path* is clean — the risk is *system-level* I/O contention, not *application-level* query contention. **Confidence: 0.70** — the risk is low (Postgres is off the voice path) but unmeasured. Accept the 03:00 CT mitigation as a pilot-scale constraint.
|

|
||||
|
||||
#### Probe 5 — SPA fallback breaking voice UI (R-DASH-03/05): Route ordering?
|
||||
|
||||
**Question:** Adding a catch-all route for React Router `/operator/*` must not break the voice UI at `/`. The catch-all must be registered BEFORE StaticFiles but AFTER API routes. Is this ordering tested? What's the rollback if the voice UI breaks?
|
||||
|
||||
**Evidence:**
|
||||
- server/__main__.py:146 — `app.mount("/", StaticFiles(directory=_CLIENT_DIST, html=True))` (current — no SPA fallback).
|
||||
- PLAN-v0.4 TASK-10-01 — catch-all route `@app.get("/{path:path}")` BEFORE StaticFiles.
|
||||
- PLAN-v0.4 TASK-10-04 — 8-assertion test (voice UI at `/`, SPA fallback for `/operator/*`, API routes return JSON, assets served by StaticFiles).
|
||||
- R-DASH-03 — "SPA fallback breaks existing voice UI (StaticFiles mount change)."
|
||||
|
||||
**Analysis:**
|
||||
The catch-all route `@app.get("/{path:path}")` is a *greedy* match — it matches *every* path. If registered before StaticFiles, it will intercept all GET requests, including `/assets/index.js`. The plan's TASK-10-01 says "the catch-all only serves index.html for client-side routes" but a `@app.get("/{path:path}")` route does not distinguish between client-side routes and static assets — it matches both. The *correct* implementation is either:
|
||||
1. A custom StaticFiles subclass that returns index.html for non-file paths (the plan's Open Question #2, line 744).
|
||||
2. A catch-all that excludes static asset paths (e.g., check if the path matches a file in `client/dist` first).
|
||||
|
||||
TASK-10-04 assertion 8 (`GET /assets/index.js` → served by StaticFiles, not the catch-all) is the *test* for this, but the *implementation* in TASK-10-01 is ambiguous. If the catch-all is registered before StaticFiles, FastAPI route matching order means the catch-all *wins* — StaticFiles never serves `/assets/index.js`. The plan's assertion 8 would *fail*.
|
||||
|
||||
**The correct ordering is: API routes → StaticFiles mount → catch-all (for SPA fallback).** But FastAPI's `app.mount("/", StaticFiles(...))` *is* a catch-all at `/` — adding another catch-all after it is redundant (StaticFiles with `html=True` already serves index.html for `/`). The *real* fix is a custom StaticFiles subclass that returns index.html for non-file paths (Open Question #2).
|
||||
|
||||
**Verdict:** The plan's TASK-10-01 catch-all approach is *subtly wrong* — a `@app.get("/{path:path}")` before StaticFiles would shadow asset serving. The correct approach is a custom StaticFiles subclass (Open Question #2) OR a catch-all *after* StaticFiles that only fires for 404s. The plan defers this to EXECUTE (Open Question #2) but the test (TASK-10-04 assertion 8) would catch the bug. **Confidence: 0.65** — the test is correct, the implementation is ambiguous. This is a binding decision.
|
||||
|
||||
**Binding Decision G-041 (MUST)** — TASK-10-01 must NOT use a `@app.get("/{path:path}")` catch-all before StaticFiles (it would shadow asset serving per assertion 8). The correct implementation is a custom StaticFiles subclass that returns `FileResponse("client/dist/index.html")` for non-file paths (Open Question #2 resolved in favor of the subclass approach). The catch-all approach is rejected. This must be documented in TASK-10-01 before EXECUTE. (0.65)

#### Probe 6 — 2-phase split: REQ-MT-02 spans P1 (schema) + P2 (pipeline). Vertical-slice violation?
|
||||
|
||||
**Question:** P1 (foundation) + P2 (dashboard) — is the split clean? REQ-MT-02 (aggregation) spans both phases (schema in P1, pipeline in P2). Is that a vertical-slice violation, or a clean layering?
|
||||
|
||||
**Evidence:**
|
||||
- PLAN-v0.4:18-19 — P1 covers "REQ-MT-02 (schema foundation)"; P2 covers "REQ-MT-02 (pipeline completion)."
|
||||
- PLAN-v0.4 REQ-ID coverage matrix (line 699) — REQ-MT-02: SLICE-01 (schema), SLICE-07 (pipeline), SLICE-10 (e2e).
|
||||
|
||||
**Analysis:**
|
||||
REQ-MT-02 is split across P1 (schema — the `cohort_aggregates` table) and P2 (pipeline — the aggregation hook + nightly job). This is *not* a vertical-slice violation — it is *clean layering*. The schema is the *contract*; the pipeline is the *implementation*. P1 ships the schema (the table exists, the PgStore has `upsert_cohort_aggregate`), P2 ships the pipeline (the hook fires, the nightly job runs). The P1→P2 dependency is *one-directional* (P2 depends on P1's schema, P1 does not depend on P2's pipeline).
|
||||
|
||||
This is the same pattern as v0.3 (mastery schema in P1, mastery flow in P1 — but the VC issuer was split, which the v0.3 grill flagged as a MUST). The difference is that REQ-MT-02's split is *schema vs. pipeline* (a clean layer), not *trigger vs. action* (the v0.3 grill's VC-issuance wiring gap). The aggregation pipeline does not need a P1 trigger — it fires on session-end, which is a P2 event (the hook is in `session_recorder.py`, which is extended in P2).
|
||||
|
||||
**Verdict:** The REQ-MT-02 split is clean layering (schema in P1, pipeline in P2), not a vertical-slice violation. The P1→P2 dependency is one-directional. The v0.3 grill's VC-issuance wiring gap (trigger in P1, action in P2) does not apply here — the aggregation trigger (session-end) is in P2. **Confidence: 0.85.**

### v0.3 Grill Deferred Items — Coverage Check
|
||||

The v0.3 grill (GRILL-v0.3.md) deferred the operator tier to v0.4. The v0.3 grill's MUST conditions were resolved *in v0.3* (formative label, scoring_inconclusive, VC interop, key rotation, VC-issuance wiring). Let me verify the v0.3 grill's deferred items are now covered in v0.4:
|
||||
|
||||
| v0.3 Grill Deferred Item | v0.4 Coverage | Status |
|
||||
|---------------------------|---------------|--------|
|
||||
| REQ-DASH-01 (cohort dashboard) | REQ-DASH-01 activated, PLAN SLICE-08/09/10 | ✅ Covered |
|
||||
| REQ-AUTH-01 (operator auth) | REQ-AUTH-01 activated, PLAN SLICE-03/05/06 | ✅ Covered |
|
||||
| REQ-MT-01 (operator Postgres) | REQ-MT-01 activated, PLAN SLICE-01/06 | ✅ Covered |
|
||||
| REQ-MT-02 (aggregation) | REQ-MT-02 activated, PLAN SLICE-01/07/10 | ✅ Covered |
|
||||
| REQ-NFR-AUTH-01 (auth NFRs) | REQ-NFR-AUTH-01 activated, PLAN SLICE-03/06 | ✅ Covered |
|
||||
| REQ-NFR-MT-01 (Postgres-in-LXC) | REQ-NFR-MT-01 activated, PLAN SLICE-01/02/06 | ✅ Covered |
|
||||
| REQ-NFR-DASH-01 (k-anon ≥10) | REQ-NFR-DASH-01 activated, PLAN SLICE-07/08/09/10 | ✅ Covered |
|
||||
| REQ-NFR-DASH-02 (freshness ≤24h) | REQ-NFR-DASH-02 activated, PLAN SLICE-07/10 | ✅ Covered |
|

|

**v0.3 grill FIX conditions carried forward to v0.4:**
|
||||
|
||||
| v0.3 Grill FIX | v0.4 Coverage | Status |
|
||||
|----------------|---------------|--------|
|
||||
| Axis 7 #2 — k-anon differencing-attack test | NOT explicitly in PLAN (TASK-07-05 tests threshold only) | ⚠️ G-038 (MUST) — add differencing-attack test |
|
||||
| Axis 6 #3 — 503 guard on operator API when Postgres down | TASK-06-01 — "auth routes return 503" if no Postgres | ✅ Covered |
|
||||
| Axis 6 #2 — stabilize learner_ref as non-reusable UUID | NOT addressed in v0.4 (HARDCODED_LEARNER_ID = "learner-1" persists) | ⚠️ Accepted as pilot-scale constraint (G-012) |
|
||||
|
||||
**Verdict:** 8/8 v0.3 deferred REQs are covered in v0.4. 1 v0.3 FIX (differencing-attack test) is not carried forward and must be added (G-038). The learner_ref stabilization (v0.3 FIX) is accepted as a pilot-scale constraint (single hardcoded learner persists).

| G-021 | 6 | No explicit token budget (pilot, full autonomy). Accept implicit budget model. | 0.75 | ACCEPT |
|

| G-026 | 7 | No external dependencies (full autonomy) | 0.90 | ACCEPT |

|
||||
| **G-041** | **Probe 5** | **MUST: TASK-10-01 must NOT use `@app.get("/{path:path}")` catch-all before StaticFiles (shadows asset serving). Use custom StaticFiles subclass returning index.html for non-file paths. Open Question #2 resolved in favor of subclass.** | **0.65** | **MUST** |

|
||||
|
||||
### Escalations
|
||||
|
||||
None. All 9 axes + meta + 6 v0.4-specific probes are resolved with confidence ≥ 0.60. The 6 MUST conditions (G-008, G-011, G-027, G-031, G-038, G-041) are binding decisions with clear resolutions — they do not require human escalation (full autonomy). The lowest-confidence binding decision is G-041 (0.65 — SPA fallback implementation) which is above the 0.60 threshold.
|
||||
|
||||
---
|
||||
|
||||
### MUST Conditions Summary (blocking — must be resolved in PLAN before EXECUTE)
|
||||
|
||||
1. **G-008 — Backup restore drill.** Add a task to P1 that executes `pg_restore --clean --if-exists` against a test Postgres and verifies the 5 tables + row counts. A nightly pg_dump that is never restored is theater.
|
||||
|
||||
2. **G-011 — Verification endpoint two-store fallback semantics.** TASK-04-04 + TASK-06-03 must explicitly document the fallback contract: (a) Postgres available → use it for key lookup (active + superseded); (b) Postgres available but credential not found → fall back to SQLite `issued_credentials` (v0.3 credentials); (c) Postgres NOT available (no DSN) → use existing v0.3 SQLite path for both keys + credentials. This is a binding contract, not an open question.
|
||||
|
||||
3. **G-027 — VC migration "no v0.3 key" edge case.** TASK-04-03 must handle the case where SQLite has no active issuer key (the pilot never issued a VC): skip the archive step, generate only the fresh v0.4 keypair. The e2e test (TASK-06-05) must include a "no v0.3 key" scenario. This is the first-boot path for most deployments.
|
||||
|
||||
4. **G-031 — R-AUTH-01 resolution reframed.** The *primary* mitigation for R-AUTH-01 is the k-anon defense-in-depth (cohort dashboard reads only k-anonymized aggregates → sniffed cookie leaks no PII). The config-driven `PRAXIS_COOKIE_SECURE` flag is *secondary* (operational convenience). The v0.3 grill's MUST #2 ("use TLS or loopback-binding") is *overridden* for the v0.4 operator-tier surface because the v0.3 grill's own formative-credential decision (MUST #1) + the k-anon defense-in-depth together resolve the tension. Document this ordering in TASK-03-02 and the v0.4 ship notes.
|
||||
|
||||
5. **G-038 — Differencing-attack test.** Add a test to TASK-07-05 or TASK-10-03: seed 10 learners in window A, 9 in window B (1 dropped), verify the API does not allow a query that isolates the dropped learner. This is a v0.3 grill FIX (Axis 7 #2) that must be carried forward.
|
||||
|
||||
6. **G-041 — SPA fallback implementation.** TASK-10-01 must NOT use a `@app.get("/{path:path}")` catch-all before StaticFiles (it would shadow asset serving — TASK-10-04 assertion 8 would fail). The correct implementation is a custom StaticFiles subclass that returns `FileResponse("client/dist/index.html")` for non-file paths. Open Question #2 is resolved in favor of the subclass approach.
|
||||
|
||||
---
|
||||
|
||||
### FIX Conditions (non-blocking — tracked in VERIFY-P1/P2)
|
||||
|
||||
- **G-003** — Document in v0.4 ship notes: dashboard validation path is test-seeded data (≥10 mock learners), not pilot traffic. At pilot scale (1 learner), k-anon suppresses all cells.
|
||||
- **G-012** — Document inherited debts: single hardcoded learner (k-anon suppresses pilot data), no TLS (R-AUTH-01 config-driven punt with k-anon defense-in-depth).
|
||||
- **G-018** — SPA fallback (R-DASH-03) is the critical-path risk. TASK-10-04 (8 assertions) is the gate. If assertion 8 fails, the fix is the custom StaticFiles subclass (G-041).
|
||||
- **G-025** — Postgres disk I/O contention (R-MT-01) is unmeasured. The 03:00 CT mitigation is a scheduling assumption. Accept as pilot-scale constraint.
|
||||
- **G-033** — Document in ship notes: v0.4 delivers the operator tier *capability*, not operator *value* (no real operator user at pilot scale).
|
||||
|
||||
---
|
||||
|
||||
### ACCEPT Items (proceed as-is)
|
||||
|
||||
- v0.4 scope is a clean handoff from v0.3 grill (G-005).
|
||||
- Architecture is conventional (G-009).
|
||||
- 4 new deps are single-purpose (G-010).
|
||||
- Key-person dependency is manageable under parallelization (G-013).
|
||||
- Phase structure is not reverse-engineered (G-017).
|
||||
- 52 tasks is evidence-based (G-019).
|
||||
- No external dependencies (G-026).
|
||||
- Rollback is per-phase git revert (G-035).
|
||||
- REQ-MT-02 split (schema in P1, pipeline in P2) is clean layering, not a vertical-slice violation (Probe 6).
|
||||
- R-VC-MIG-01 "archive before activate" + e2e test is sufficient (Probe 2, with G-027 edge case).
|
||||
|
||||
---
|
||||
|
||||
### Bottom Line
|
||||
|
||||
The v0.4 plan is **not unfeasible** — the research is thorough, the architecture is conventional, the phase split is clean, and the v0.3 grill's deferred obligation is honestly delivered. The plan is **not over-scoped** (8 REQs, single operator role, k-anon not DP). The plan is **not under-tested** in its highest-risk areas (R-VC-MIG-01 has a dedicated e2e test, R-DASH-03 has 8 assertions).
|
||||
|
||||
The 6 MUST conditions are surgical:
|
||||
- 2 are *missing tasks* (backup drill, differencing-attack test).
|
||||
- 2 are *specification clarifications* (verification endpoint fallback, VC migration edge case).
|
||||
- 1 is a *reframing* (R-AUTH-01: k-anon defense-in-depth is the primary mitigation, not the config flag).
|
||||
- 1 is an *implementation correction* (SPA fallback: custom StaticFiles subclass, not a catch-all route).
|
||||
|
||||
Resolve the 6 MUSTs, track the 5 FIXs, and v0.4 is a **GO**.

## v0.3 Persona Roster
|
||||
|
||||
### Active personas (5)
|
||||
|
||||
The v0.3 milestone is **mastery-backend + operator-frontend + security-heavy**. The frontend-engineer **reactivates** (cohort dashboard UI — D-044). A new **security-engineer** persona is added (VC crypto + auth — D-033/D-041/D-042). The devops-engineer from v0.2 is **deactivated** (no new deploy scripts in v0.3 — the Postgres-in-LXC addition is owned by backend-engineer + data-engineer since it's a docker-compose service addition, not a deploy-script change). The data-engineer expands territory to cover the Postgres operator-tier schema.

## v0.3 Notes for PLAN/EXECUTE
|
||||
|
||||
- Territory enforcement mode: `warn` (per config.json `personas.territory_enforcement`)
|
||||
- The **backend-engineer owns the majority of v0.3 task surface** (mastery engine + IRT + library + paths + cohort aggregation + operator API + Postgres wiring). This is the largest backend surface since v0.1.
|
||||
- The **security-engineer's v0.3 surface is the most security-critical**: VC issuer keys + operator auth. Any P0/P1 finding here blocks ship.
|
||||
- The **frontend-engineer reactivates** after v0.2 deactivation — the cohort dashboard is the first client-side feature since v0.1.
|
||||
- The **data-engineer's v0.3 surface spans two stores** (SQLite v0.3 tables + Postgres operator tier) — the hybrid pattern (D-031) is the architectural concern.
|
||||
- Cross-persona collaboration points:
|
||||
- backend-engineer (mastery_gate_event write) ↔ data-engineer (Postgres schema) ↔ security-engineer (VC issuance on gate-open)
|
||||
- frontend-engineer (dashboard UI) ↔ backend-engineer (operator API) ↔ data-engineer (k-anonymity queries)
|
||||
- security-engineer (issuer key) ↔ data-engineer (issuer_keys table, encrypted-at-rest)
|
||||
- The security-engineer is NOT in config.json `personas` — emergent persona defined in PERSONAS.md (same pattern as v0.2 devops-engineer). Territory enforcement (warn mode) picks up globs from PERSONAS.md.
|
||||
- R-AUTH-01 (Secure cookie + no-TLS) is a security-engineer + lead-developer collaboration point for PLAN.

# Praxis — Persona Assessment (v0.4 Operator Tier)
|
||||
|
||||
> **Generated:** v0.4 RESEARCH stage
|
||||
> **Project:** Praxis (v0.4 — operator tier: cohort dashboard, auth, Postgres)
|
||||
> **Source:** v0.4 RESEARCH-v0.4-operator-tier.md + v0.4 REQUIREMENTS.md (REQ-MT-01/02, REQ-AUTH-01, REQ-DASH-01, 4 NFRs) + actual `pyproject.toml` + `client/package.json` + `server/` structure

## v0.4 Persona Roster
|
||||
|
||||
### Active personas (6)
|
||||
|
||||
The v0.4 milestone is **operator-tier-backend + dashboard-frontend + security-crypto + Postgres-in-LXC**. The frontend-engineer (reactivated in v0.3 anticipatory, now confirmed for v0.4 dashboard UI) and devops-engineer (deactivated in v0.3, reactivated for Postgres-in-LXC + backup + bootstrap script) are both active. The security-engineer is retained (VC key migration SQLite→Postgres + auth stack + Secure-cookie-TLS resolution). The data-engineer expands to the Postgres operator-tier schema + aggregation SQL. All 6 personas are active — the largest roster since v0.1.

```yaml
|

---
|
||||
name: lead-developer
|
||||
active: true
|
||||
phase_specific: false
|
||||
reason: Coordinates task decomposition across Postgres/auth/cohort/dashboard/VC-migration domains. Resolves conflicts between backend (operator API + aggregation), security (auth + VC key migration), data (Postgres schema + k-anon), frontend (dashboard UI), and devops (Postgres service + CT bump + backup). Owns the docker-compose.yml Postgres service addition (spans data + backend + devops). Required for every milestone.

|

name: backend-engineer
|
||||
active: true
|
||||
phase_specific: false
|
||||
reason: Owns the asyncpg pool wiring (app.state.pg_pool via lifespan — D-050), the operator API routes (server/operator/ — 8 endpoints per D-053/D-057), the cohort aggregation pipeline (server/cohort/ — on-session-end async hook + nightly reconciliation job per D-054), and the session_recorder.py extension to chain the aggregation hook after the mastery flow. Also owns the SPA fallback route in server/__main__.py (required for React Router /operator/* routes). The aggregation pipeline is the largest new backend territory in v0.4.

name: frontend-engineer

active: true

phase_specific: false
|
||||
reason: REACTIVATED (confirmed for v0.4 — was anticipatory in v0.3). Owns the React cohort dashboard UI (client/src/operator/ — D-044, REQ-DASH-01, D-053). Auth-gated /operator/* routes + 3 k-anonymized views (practice volume, mastery progression, failure patterns). Adds React Router (react-router-dom@^7 — NEW dep) for /operator/* routing. Renders read-only tables + inline SVG sparklines (zero-dep, ~50 LOC). Auth gate: GET /api/operator/me on mount → redirect to /operator/login if 401. Reuses v0.2 StaticFiles (same client/dist build — D-044). No separate SPA build.

name: data-engineer

active: true

phase_specific: false
|
||||
reason: EXPANDED territory for v0.4. Owns the Postgres operator-tier schema (operators, issued_credentials, mastery_gate_events, cohort_aggregates, issuer_keys — D-040, refined by D-050..D-053), the db/pg_migrations/ migration runner (mirrors the existing db/migrate.py pattern), the db/pg_store.py (asyncpg-backed Postgres store), the IssuerKeyStore protocol/ABC (D-051 migration — both PraxisStore and PgStore implement it), and the k-anonymity suppression SQL (D-034 — write-time COUNT(DISTINCT learner_ref) >= 10 check). The hybrid SQLite+Postgres storage pattern (D-031) is the data-engineer's architectural concern — no cross-DB joins, opaque learner_ref. The cohort_aggregates table is a plain table (NOT partitioned — v0.4 scale; partitioning deferred post-pilot per RESEARCH-v0.4 §1.7).

active: true

|

reason: RETAINED from v0.3. Owns the VC issuer key migration (D-051 — SQLite→Postgres, v0.3 public key archived as superseded, fresh v0.4 keypair, encrypted at rest) and the operator auth stack (D-041, D-056, D-057 — argon2id passwords, signed stateless cookies via Starlette SessionMiddleware, slowapi 5/min rate limit, server-side auth enforcement on every /api/operator/* request). The Secure-cookie-TLS tension (R-AUTH-01) is the security-engineer's v0.4 collaboration point with lead-developer — resolution is config-driven PRAXIS_COOKIE_SECURE (default true; false for HTTP pilot with logged WARNING). The VC key migration is high-severity risk R-VC-MIG-01 — archiving the v0.3 public key before activating the new key is security-critical. argon2-cffi PasswordHasher defaults (t=3, m=64MiB, p=4) exceed OWASP minimums (verified 2026-08-04).

|
||||
reason: REACTIVATED for v0.4 (was deactivated in v0.3 — no deploy scripts). v0.4 adds Postgres as a second Docker service in the existing LXC CT (D-040), which is devops territory: the docker-compose Postgres service definition + praxis-net bridge network + pgdata/pgbackups named volumes + pg_isready healthcheck + CT memory bump (4GB→6GB) + host-side cron for nightly pg_dump backup (D-055) + the scripts/create-operator.py bootstrap CLI (D-052) + .env.example operator vars (PRAXIS_PG_PASSWORD, PRAXIS_COOKIE_SECRET, PRAXIS_BOOTSTRAP_OPERATOR_USER/PASS, PRAXIS_VC_ISSUER_KEY). The Postgres-in-LXC addition is NOT just a docker-compose service addition (as v0.3 assumed) — it involves CT resource bump (lxc-config.sh memory change), backup cron setup, and the bootstrap script. Will deactivate again in v0.5 unless deploy hardening continues.

## Framework Alignment (v0.4 — from actual pyproject.toml + client/package.json)
|
||||
|
||||
| Persona | Frameworks (v0.4 research-aligned) | New in v0.4 | Source |
|
||||
|---------|-------------------------------------|-------------|--------|
|
||||
| lead-developer | pipecat, fastapi, postgres, docker | — | `pyproject.toml` + `docker-compose.yml` |
|
||||
| backend-engineer | pipecat, pydantic, fastapi, uvicorn, asyncpg, aiosqlite | **asyncpg** | `pyproject.toml` |
|
||||

|
||||
| data-engineer | sqlite, postgres16, aiosqlite, asyncpg, alembic-style-migrations | **postgres16, asyncpg** | `pyproject.toml` + `db/migrate.py` |
|
||||
| security-engineer | pynacl, canonicaljson, base58, argon2-cffi, starlette-sessionmiddleware, slowapi, itsdangerous | **argon2-cffi, slowapi** | `pyproject.toml` + RESEARCH-v0.4 |

|
||||
|
||||
## Territory Alignment (v0.4 — from actual server/ structure)
|
||||
|
||||
The actual `server/` structure: `asr/`, `tts/`, `llm/`, `guardrails/`, `scenarios/`, `mastery/`, `paths/`, `vc/`, `services/`, `pipeline.py`, `session_recorder.py`, `__main__.py`, `cost.py`, `debrief.py`, `latency.py`, `interruptibility.py`. v0.4 adds: `server/operator/` (operator API), `server/auth/` (auth middleware), `server/cohort/` (aggregation pipeline), `db/pg_store.py`, `db/pg_migrate.py`, `db/pg_migrations/`, `db/pg_schema.sql`, `scripts/create-operator.py`, `client/src/operator/`.
|
||||
|
||||
Key territory boundaries:
|
||||
- **docker-compose.yml** → lead-developer (spans praxis + postgres services + networks + volumes; collaborates with data + devops)
|
||||
- **server/__main__.py** (SPA fallback) → backend-engineer (the catch-all route before StaticFiles mount — D-044 SPA fallback)
|
||||
- **server/operator/** → backend-engineer (operator API routes)
|
||||
- **server/auth/** → security-engineer (auth middleware, argon2, cookies, rate limit)
|
||||
- **server/cohort/** → backend-engineer (aggregation pipeline — hook + nightly job)
|
||||
- **server/vc/issuer_keys.py** → security-engineer (IssuerKeyStore protocol refactor — D-051)
|
||||
- **db/pg_store.py + db/pg_schema.sql + db/pg_migrations/** → data-engineer (Postgres store + schema + migrations)
|
||||
- **scripts/create-operator.py** → devops-engineer (operator bootstrap CLI — D-052)
|
||||
- **scripts/proxmox/** → devops-engineer (CT memory bump if lxc-config.sh changes)
|
||||
- **client/src/operator/** → frontend-engineer (dashboard UI)
|
||||
- **client/src/App.tsx** → frontend-engineer (React Router wrapper + SPA fallback integration)
|
||||
- **client/package.json** → frontend-engineer (react-router-dom addition)
|
||||
- **.env.example** → devops-engineer (operator vars: PRAXIS_PG_PASSWORD, PRAXIS_COOKIE_SECRET, PRAXIS_BOOTSTRAP_OPERATOR_USER/PASS, PRAXIS_VC_ISSUER_KEY)
|
||||
|
||||
## Constraint Alignment (v0.4-specific)
|
||||
|
||||
- **All personas:** `hybrid-storage-no-cross-db-joins` (D-031), `k-anonymity-floor-10` (D-034), `no-raw-learner-pii-in-postgres` (D-031).
|
||||
- **lead-developer:** `aggregation-off-voice-path` (D-054 — async fire-and-forget, must not block session-end response).
|
||||
- **backend-engineer:** `mastery-off-voice-path` (C-8 carry-forward), `aggregation-off-voice-path` (D-054), `asyncpg-pool-on-app-state` (D-050 — pool created in lifespan, not per-request), `routes-before-static-mount` (carry-forward + SPA fallback catch-all before StaticFiles).
|
||||
- **frontend-engineer:** `auth-gated-operator-routes` (D-057), `k-anonymity-display-suppressed-cells` (D-034 — render "— (<10 learners)" for suppressed cells), `no-raw-learner-pii-in-ui` (D-031), `spa-fallback-for-operator-routes` (new — React Router needs index.html fallback), `inline-svg-sparklines-no-chart-lib` (RESEARCH-v0.4 §4.3 — zero-dep sparklines).
|
||||
- **data-engineer:** `no-cross-db-joins` (D-031), `opaque-learner-ref` (D-031 — learner_ref is opaque string, not FK), `write-time-suppression` (D-034 — cell suppression at write time, not read time), `plain-table-no-partitions-v0.4` (RESEARCH-v0.4 §1.7 — partitioning deferred post-pilot), `gen-random-uuid-no-extension` (PG16 core, no pgcrypto).
|
||||
- **security-engineer:** `argon2id-passwords-owasp-minimums` (D-041 + OWASP — PasswordHasher defaults exceed minimums), `config-driven-secure-cookie` (R-AUTH-01 resolution — PRAXIS_COOKIE_SECURE env var), `issuer-key-encrypted-at-rest` (D-042 — nacl.SecretBox with PRAXIS_VC_ISSUER_KEY root key), `superseded-not-revoked` (D-051 — v0.3 public key archived as superseded, not revoked), `server-side-auth-enforcement` (D-057 — server checks cookie on every /api/operator/* request, React guard is UX only), `public-verification-no-pii` (D-043 carry-forward).
|
||||
- **devops-engineer:** `idempotent-deploy` (carry-forward), `secrets-never-committed` (carry-forward), `pg-dump-backup-retention-7d` (D-055 — %u day-of-week rolling 7-file), `host-side-cron-decoupled-from-app` (RESEARCH-v0.4 §1.5 — backup runs even if praxis is down), `ct-memory-bump-6gb` (REQ-NFR-MT-01 — 4GB→6GB).
|
||||
|
||||
## Phase-Specific Personas
|
||||
|
||||
Two personas are **phase-specific** for v0.4:
|
||||
|
||||
1. **security-engineer** — `phase_specific: true`. Retained from v0.3 (was new in v0.3 for VC crypto). May persist into v0.9 (credentialing) but deactivate in between if no security-crypto work. The VC key migration + auth stack are the v0.4 security-critical surfaces.
|
||||
|
||||
2. **devops-engineer** — `phase_specific: true`. Reactivated from v0.2 (was deactivated in v0.3). v0.4 is Postgres-in-LXC heavy (docker-compose service + CT bump + backup + bootstrap). Will deactivate again in v0.5 unless deploy hardening continues.
|
||||
|
||||
## v0.4 Notes for PLAN/EXECUTE
|
||||
|
||||
- Territory enforcement mode: `warn` (per config.json `personas.territory_enforcement`)
|
||||
- The **backend-engineer owns the largest v0.4 task surface**: asyncpg pool + operator API (8 endpoints) + aggregation pipeline (hook + nightly job) + session_recorder extension + SPA fallback. This is the largest backend surface since v0.3.
|
||||
- The **frontend-engineer reactivates for confirmed dashboard work** (v0.3 was anticipatory; v0.4 is the real dashboard implementation). React Router addition + SPA fallback + 3 k-anonymized views + inline SVG sparklines.
|
||||
- The **security-engineer's v0.4 surface is high-severity**: VC key migration (R-VC-MIG-01 — archiving v0.3 public key is security-critical) + auth stack (R-AUTH-01 — Secure cookie + no-TLS resolution).
|
||||
- The **data-engineer's v0.4 surface spans two stores** (SQLite v0.3 + Postgres v0.4) + the IssuerKeyStore protocol (D-051 migration bridge).
|
||||
- The **devops-engineer's v0.4 surface is smaller than v0.2** but critical: docker-compose Postgres service + CT memory bump + backup cron + bootstrap script.
|
||||
- Cross-persona collaboration points:
|
||||
- backend-engineer (aggregation hook in session_recorder) ↔ data-engineer (cohort_aggregates schema + suppression SQL) ↔ security-engineer (learner_ref is opaque, no PII)
|
||||
- frontend-engineer (dashboard UI) ↔ backend-engineer (operator API endpoints) ↔ data-engineer (k-anonymity queries)
|
||||
- security-engineer (IssuerKeyStore protocol) ↔ data-engineer (PgStore implements it) — D-051 migration
|
||||
- security-engineer (auth middleware) ↔ backend-engineer (operator API router dependencies) — D-057
|
||||
- devops-engineer (docker-compose Postgres) ↔ lead-developer (compose file owner) ↔ data-engineer (pgdata volume + schema)
|
||||
- devops-engineer (create-operator.py) ↔ security-engineer (argon2id hashing) — D-052
|
||||
- The **security-engineer and devops-engineer are NOT in config.json `personas`** — emergent personas defined in PERSONAS.md (same pattern as v0.2/v0.3). Territory enforcement (warn mode) picks up globs from PERSONAS.md.
|
||||
- R-AUTH-01 (Secure cookie + no-TLS) is a security-engineer + lead-developer collaboration point for GRILL-v0.4 (config-driven flag resolution must be grill-approved).
|
||||
- R-VC-MIG-01 (VC key migration) is a security-engineer + data-engineer collaboration point (archive v0.3 public key before activating new key).

## Phase Split Rationale
|
||||
|
||||
v0.4 is split into 2 execution phases + final review, following the ROADMAP:
|
||||
|
||||
- **P1 (Operator Foundation — Postgres + Auth):** docker-compose Postgres 16 service, asyncpg pool, Postgres operator-tier schema (5 tables), operator auth (argon2id + signed stateless cookies + slowapi rate limit), VC issuer key migration SQLite→Postgres (archive v0.3 public key as `superseded`, fresh v0.4 keypair), operator bootstrap CLI. No UI. Shippable as `v0.1.7`. Covers: REQ-MT-01, REQ-AUTH-01, REQ-NFR-AUTH-01, REQ-NFR-MT-01 + REQ-MT-02 (schema foundation).
|
||||
- **P2 (Cohort Dashboard + Aggregation):** cohort aggregation pipeline (on-session-end async hook + nightly reconciliation at 03:00 CT, k-anonymity ≥ 10 write-time suppression), React cohort dashboard (3 views: practice/mastery/failure-patterns), `/api/operator/*` cohort endpoints (auth-gated), React Router + SPA fallback. Shippable as `v0.1.8`. Covers: REQ-DASH-01, REQ-NFR-DASH-01, REQ-NFR-DASH-02 + REQ-MT-02 (pipeline completion).
|
||||
- **P3 (Final — Review + Ship):** multi-persona review, audit, merge to main, milestone release `v0.1.9` = v0.4.
|
||||
|
||||
The split keeps P1 a clean infra/auth milestone (no UI, verifiable by tests + CLI), and P2 a clean feature milestone (dashboard + pipeline, verifiable by UI + API tests).

## Key Decisions Honored (D-050..D-057 + research)
|
||||
|
||||
| Decision | Honored in | How |
|
||||
|----------|-----------|-----|
|
||||
| D-050 (asyncpg pool min 1/max 10 on app.state.pg_pool via lifespan) | SLICE-01 | lifespan creates pool on startup, closes on shutdown |
|
||||
| D-051 (VC key migration — fresh keypair in Postgres, v0.3 public key archived as superseded) | SLICE-04, SLICE-06 | migration script archives v0.3 pubkey + generates v0.4 key; e2e test verifies old VC |
|
||||
| D-052 (scripts/create-operator.py CLI) | SLICE-05 | idempotent insert, argon2id hash, env-provided credentials |
|
||||
| D-053 (3 dashboard views) | SLICE-08, SLICE-09 | practice/mastery/failure-patterns endpoints + React components |
|
||||
| D-054 (async fire-and-forget hook + nightly 03:00 CT) | SLICE-07 | asyncio.Task on session end + in-process scheduler loop |
|
||||
| D-055 (nightly pg_dump to volume, 7-day retention) | SLICE-02 | host-side cron script, %u rolling 7-file |
|
||||
| D-056 (signed stateless cookies, Starlette SessionMiddleware) | SLICE-03 | itsdangerous HMAC-SHA256, no sessions table |
|
||||
| D-057 (server-side auth on every /api/operator/* + React guard) | SLICE-03, SLICE-09 | router-level dependencies + GET /api/operator/me on mount |
|
||||
| R-AUTH-01 (config-driven PRAXIS_COOKIE_SECURE) | SLICE-03 | env var default true; false for HTTP pilot with logged WARNING |
|
||||
| SPA fallback for React Router /operator/* | SLICE-10 | catch-all route before StaticFiles mount |
|
||||
| Inline SVG sparklines (zero-dep) | SLICE-09 | ~50 LOC component, no chart library |
|
||||
| cohort_aggregates plain table (not partitioned) | SLICE-01 | schema ships with (path, window_start) index, no partitioning |

## SLICE-01: Postgres DB Foundation (W1)
|
||||
|
||||
- **Goal:** Stand up Postgres 16 as a second Docker service with asyncpg pool, migration runner, and the full operator-tier schema (5 tables). The critical-path foundation for all P1/P2 work.
|
||||
- **REQ-IDs covered:** REQ-MT-01 (Postgres store), REQ-NFR-MT-01 (Postgres-in-LXC without destabilizing learner service), REQ-MT-02 (schema foundation — cohort_aggregates table)
|
||||
- **Wave:** 1
|
||||
- **Dependencies:** none
|
||||
- **Primary persona:** lead-developer
|
||||
- **Supporting personas:** data-engineer (schema + migrations + pg_store + pg_migrate), backend-engineer (pool lifespan), devops-engineer (compose volumes/network consultation)
|
||||
|
||||
### Tasks
|
||||
|
||||
#### TASK-01-01 — docker-compose Postgres service + praxis-net + volumes
|
||||
- **Persona:** lead-developer
|
||||
- **File:** `docker-compose.yml` (extend)
|
||||
- **Content:** Add `postgres` service (postgres:16-slim, restart: unless-stopped, env: POSTGRES_USER/PASSWORD/DB/PGDATA, env_file server.env, pgdata+pgbackups volumes, pg_isready healthcheck 10s/5ret/5s timeout, praxis-net network, no published ports). Add `praxis` service `depends_on: { postgres: { condition: service_healthy } }` + `networks: [praxis-net]`. Add `pgdata`, `pgbackups` named volumes + `praxis-net` bridge network. Keep existing `praxis-data` volume + all v0.2 env vars.
|
||||
- **Acceptance criteria:** `docker compose config` validates; `docker compose up -d postgres` → healthcheck passes within 30s; praxis service starts after postgres healthy; no published port on postgres (verified `docker port` shows nothing).
|
||||
|
||||
#### TASK-01-02 — pyproject.toml new deps
|
||||
- **Persona:** lead-developer
|
||||
- **File:** `pyproject.toml` (extend)
|
||||
- **Content:** Add `asyncpg>=0.29`, `argon2-cffi>=23.1`, `slowapi>=0.1` to dependencies. These are the 3 new v0.4 pip deps (RESEARCH-v0.4 §new-deps).
|
||||
- **Acceptance criteria:** `pip install -e .` succeeds; `import asyncpg`, `import argon2`, `import slowapi` all work.
|
||||
|
||||
#### TASK-01-03 — asyncpg pool lifespan in server/__main__.py
|
||||
- **Persona:** backend-engineer
|
||||
- **File:** `server/__main__.py` (extend — add lifespan)
|
||||
- **Content:** Add `@asynccontextmanager async def lifespan(app)` that creates `asyncpg.create_pool(dsn=os.environ["PRAXIS_PG_DSN"], min_size=1, max_size=10, command_timeout=10)` on `app.state.pg_pool`, runs `pg_migrate.apply_pg_migrations(pool)` on startup, closes pool on shutdown. Pass `lifespan=lifespan` to `FastAPI(...)`. If `PRAXIS_PG_DSN` is unset, log WARNING and skip pool (graceful — dev mode without Postgres). The existing `_store` (PraxisStore/SQLite) remains for learner state.
|
||||
- **Acceptance criteria:** With Postgres running, `app.state.pg_pool` is an asyncpg.Pool instance on startup; migrations applied (tables exist); pool closed cleanly on shutdown. Without Postgres (no DSN), server starts with WARNING, learner voice loop still works (SQLite unaffected).
|
||||
|
||||
#### TASK-01-04 — db/pg_migrate.py — asyncpg migration runner
|
||||
- **Persona:** data-engineer
|
||||
- **File:** `db/pg_migrate.py` (new)
|
||||
- **Content:** Mirror `db/migrate.py` pattern. `async def apply_pg_migrations(pool: asyncpg.Pool) -> list[str]` — creates `_pg_migrations` tracking table, reads `db/pg_migrations/*.sql` in sorted order, applies pending migrations within a transaction, records in `_pg_migrations`. Idempotent — no-op if all applied. Retries on connection failure (3 attempts, 2s backoff — R-MT-02 mitigation).
|
||||
- **Acceptance criteria:** Re-running `apply_pg_migrations(pool)` is a no-op (returns empty list). Migration files apply in order. Connection failure retries 3x then raises.
|
||||
|
||||
#### TASK-01-05 — db/pg_schema.sql + db/pg_migrations/0001_operator_tier.sql
|
||||
- **Persona:** data-engineer
|
||||
- **Files:** `db/pg_schema.sql` (new — reference), `db/pg_migrations/0001_operator_tier.sql` (new — applied by pg_migrate)
|
||||
- **Content:** 5 tables per ARCHITECTURE.md §Postgres Schema:
|
||||
- `operators` (id UUID DEFAULT gen_random_uuid() PK, username TEXT UNIQUE NOT NULL, password_hash TEXT NOT NULL, display_name TEXT, role TEXT DEFAULT 'operator', is_active BOOLEAN DEFAULT TRUE, created_at TIMESTAMPTZ DEFAULT now(), last_login_at TIMESTAMPTZ)
|
||||
- `issued_credentials` (id UUID PK, operator_id UUID REFERENCES operators, learner_ref TEXT NOT NULL, vc_type TEXT, payload_jsonb JSONB NOT NULL, signature_b64 TEXT NOT NULL, status TEXT DEFAULT 'active', issued_at TIMESTAMPTZ DEFAULT now(), revoked_at TIMESTAMPTZ)
|
||||
- `mastery_gate_events` (id UUID DEFAULT gen_random_uuid() PK, learner_ref TEXT NOT NULL, scenario_id TEXT, path_id TEXT NOT NULL, gate_outcome TEXT, rubric_scores_jsonb JSONB, recorded_at TIMESTAMPTZ DEFAULT now(), source TEXT DEFAULT 'sync')
|
||||
- `cohort_aggregates` (path TEXT NOT NULL, metric TEXT NOT NULL, window_start DATE NOT NULL, window_end DATE NOT NULL, value NUMERIC, cell_count INTEGER NOT NULL DEFAULT 0, cell_suppressed BOOLEAN NOT NULL DEFAULT FALSE, updated_at TIMESTAMPTZ DEFAULT now(), PRIMARY KEY (path, metric, window_start)) — **plain table, NOT partitioned** (D-050..D-053; RESEARCH-v0.4 §1.7). Index on `(path, window_start)`.
|
||||
- `issuer_keys` (id TEXT PK, public_key TEXT NOT NULL, private_key_enc BYTEA, status TEXT NOT NULL DEFAULT 'active', created_at TIMESTAMPTZ DEFAULT now())
|
||||
- All use `gen_random_uuid()` (PG16 core, no extension — R-MT-05 verified).
|
||||
- **Acceptance criteria:** `apply_pg_migrations(pool)` creates all 5 tables + `_pg_migrations` tracking table. `\d operators` in psql shows expected columns. `gen_random_uuid()` works without extension. `cohort_aggregates` has no partitioning (confirmed via `\d+`).
|
||||
|
||||
#### TASK-01-06 — db/pg_store.py — PgStore class
|
||||
- **Persona:** data-engineer
|
||||
- **File:** `db/pg_store.py` (new)
|
||||
- **Content:** `class PgStore` — accepts an `asyncpg.Pool` in constructor. Methods:
|
||||
- Operator CRUD: `get_operator_by_username(username) -> dict | None`, `get_operator_by_id(id) -> dict | None`, `update_last_login(id)`, `insert_operator(username, password_hash, display_name) -> str` (ON CONFLICT DO NOTHING, returns id).
|
||||
- Cohort aggregate read: `get_cohort_aggregates(path, metric, since_date) -> list[dict]` (returns rows with value, cell_count, cell_suppressed, updated_at).
|
||||
- Cohort aggregate write: `upsert_cohort_aggregate(path, metric, window_start, window_end, value, cell_count, cell_suppressed)` (ON CONFLICT (path, metric, window_start) DO UPDATE).
|
||||
- Issuer key methods (implements IssuerKeyStore protocol — SLICE-04): `init_issuer_key(key_id, public_key, private_key_enc)`, `get_active_signing_key_row() -> dict | None`, `get_public_key_row(key_id) -> dict | None`, `set_issuer_key_superseded(key_id)`.
|
||||
- Credential methods: `insert_credential(...)`, `get_credential(id) -> dict | None`, `set_credential_status(id, status)`.
|
||||
- Mastery gate event: `record_gate_event(learner_ref, path_id, scenario_id, gate_outcome, rubric_scores_jsonb)`.
|
||||
- All async, use `pool.acquire()` context manager.
|
||||
- **Acceptance criteria:** Each method has a unit test with a real Postgres pool (testcontainers or local PG). Round-trip insert+query works. ON CONFLICT upsert is idempotent. No cross-DB joins (D-031). `learner_ref` is opaque string (not FK).
|
||||
|
||||
#### TASK-01-07 — PgStore + pool integration test
|
||||
- **Persona:** data-engineer
|
||||
- **File:** `tests/test_pg_store.py` (new)
|
||||
- **Content:** Integration test requiring a Postgres instance (skip if `PRAXIS_PG_DSN` not set). Tests: pool creation, migration application, operator insert+query, cohort_aggregate upsert idempotency, issuer_key insert+query, credential insert+query. Verifies the full DB stack works end-to-end.
|
||||
- **Acceptance criteria:** All tests pass when Postgres is available; tests skip gracefully when `PRAXIS_PG_DSN` is unset (no hard CI dependency on Postgres).
|
||||
|
||||
---
|
||||
|
||||
## SLICE-02: DevOps Config — .env.example + CT Bump + Backup (W1)
|
||||
|
||||
- **Goal:** Update deployment config for Postgres-in-LXC: operator env vars, CT memory bump (4→6GB), nightly backup cron script.
|
||||
- **REQ-IDs covered:** REQ-NFR-MT-01 (Postgres-in-LXC without destabilizing — CT sizing + backup)
|
||||
- **Wave:** 1
|
||||
- **Dependencies:** none (parallel with SLICE-01 — disjoint files: .env.example, scripts/proxmox/ vs docker-compose.yml, db/, server/)
|
||||
- **Primary persona:** devops-engineer
|
||||
- **Supporting personas:** lead-developer (compose env consultation)
|
||||
|
||||
### Tasks
|
||||
|
||||
#### TASK-02-01 — .env.example operator vars
|
||||
- **Persona:** devops-engineer
|
||||
- **File:** `.env.example` (extend)
|
||||
- **Content:** Add v0.4 operator vars with documentation comments:
|
||||
- `PRAXIS_PG_PASSWORD` (Postgres password — secret)
|
||||
- `PRAXIS_PG_DSN` (full DSN: `postgresql://praxis:${PRAXIS_PG_PASSWORD}@postgres:5432/praxis`)
|
||||
- `PRAXIS_COOKIE_SECRET` (≥32 bytes random — secret)
|
||||
- `PRAXIS_COOKIE_SECURE` (default `true`; set `false` for HTTP pilot — R-AUTH-01)
|
||||
- `PRAXIS_BOOTSTRAP_OPERATOR_USER` (initial operator username — secret)
|
||||
- `PRAXIS_BOOTSTRAP_OPERATOR_PASS` (initial operator password — secret)
|
||||
- `PRAXIS_VC_ISSUER_KEY` (VC issuer root key — already in v0.3, document for v0.4 migration)
|
||||
- **Acceptance criteria:** `.env.example` is documentation-only (no real secrets). All vars have comments explaining purpose + when to set. File is gitignored-safe (`.env.example` is committed, `.env.secrets` is not — verified in `.gitignore`).
|
||||
|
||||
#### TASK-02-02 — CT memory bump in lxc-clone.sh
|
||||
- **Persona:** devops-engineer
|
||||
- **File:** `scripts/proxmox/lxc-clone.sh` (extend)
|
||||
- **Content:** Change `memory=${PROXMOX_MEMORY_MB:-4096}` → `memory=${PROXMOX_MEMORY_MB:-6144}` (4GB→6GB per REQ-NFR-MT-01, RESEARCH-v0.4 §1.1). Add comment explaining Postgres ~400MB + praxis ~500MB + Docker ~200MB + build headroom ~1GB + margin.
|
||||
- **Acceptance criteria:** `lxc-clone.sh` defaults to 6144MB. Existing override via `PROXMOX_MEMORY_MB` env still works. Bats tests (if any check memory) updated.
|
||||
|
||||
#### TASK-02-03 — Backup cron script
|
||||
- **Persona:** devops-engineer
|
||||
- **File:** `scripts/backup-pg.sh` (new)
|
||||
- **Content:** Host-side cron script (decoupled from praxis service uptime — RESEARCH-v0.4 §1.5). Runs `docker compose exec -T postgres pg_dump -U praxis -Fc praxis -f /backups/praxis-$(date +%u).dump`. The `%u` = day-of-week 1-7 → rolling 7-file retention with zero cleanup logic (D-055). Includes a restore drill comment block: `pg_restore --clean --if-exists /backups/praxis_3.dump` (never restore into live DB without stopping praxis first). Script is idempotent — overwrites the day-of-week file.
|
||||
- **Acceptance criteria:** Script executes without error when postgres is running. Produces a compressed dump file at `/backups/praxis-<dow>.dump`. Re-running overwrites the same file. Restore drill documented in comments. Script is POSIX-sh compatible (no bashisms).
|
||||
|
||||
---
|
||||
|
||||
## SLICE-03: Operator Auth Module (W2)
|
||||
|
||||
- **Goal:** Implement the operator auth stack: argon2id password hashing, signed stateless cookies (Starlette SessionMiddleware), slowapi rate limiting, and the `current_operator` dependency. The auth route handlers (login/logout/me) are in this slice; __main__.py mounting is in SLICE-06.
|
||||
- **REQ-IDs covered:** REQ-AUTH-01, REQ-NFR-AUTH-01
|
||||
- **Wave:** 2
|
||||
- **Dependencies:** SLICE-01 (operators table + PgStore for operator lookup)
|
||||
- **Primary persona:** security-engineer
|
||||
- **Supporting personas:** backend-engineer (FastAPI route patterns)
|
||||
|
||||
### Tasks
|
||||
|
||||
#### TASK-03-01 — argon2id password hashing
|
||||
- **Persona:** security-engineer
|
||||
- **File:** `server/auth/passwords.py` (new)
|
||||
- **Content:** `from argon2 import PasswordHasher`. `_ph = PasswordHasher()` (defaults: time_cost=3, memory_cost=64MiB, parallelism=4 — exceeds OWASP minimums per RESEARCH-v0.4 §2.1). `hash_password(plain: str) -> str`, `verify_password(stored_hash: str, plain: str) -> bool` (catches VerifyMismatchError → False), `needs_rehash(stored_hash: str) -> bool` (delegates to `_ph.check_needs_rehash`). Login flow calls `needs_rehash` after successful verify → rehash if params bumped.
|
||||
- **Acceptance criteria:** hash→verify round-trip works. Wrong password returns False (no exception). `needs_rehash` returns False for current defaults, True if params are bumped. Hashing latency < 1s (R-AUTH-02 — single operator, low frequency).
|
||||
|
||||
#### TASK-03-02 — Signed cookie configuration (SessionMiddleware)
|
||||
- **Persona:** security-engineer
|
||||
- **File:** `server/auth/cookies.py` (new)
|
||||
- **Content:** `def get_session_middleware_kwargs() -> dict` — returns kwargs for `SessionMiddleware`: `secret_key=os.environ["PRAXIS_COOKIE_SECRET"]`, `session_cookie="praxis_op"`, `max_age=28800` (8h — D-041), `httponly=True`, `samesite="strict"`, `secure=_env_bool("PRAXIS_COOKIE_SECURE", True)`, `path="/"`. If `PRAXIS_COOKIE_SECURE=false`, log WARNING: "Cookie Secure flag disabled — HTTP pilot mode (R-AUTH-01). Do not use in production." `_env_bool` parses "true"/"false"/"1"/"0". If `PRAXIS_COOKIE_SECRET` is unset, generate a random one + log WARNING (dev only — not for pilot).
|
||||
- **Acceptance criteria:** Cookie kwargs match D-041/D-056 spec. `secure=False` logs WARNING. Missing secret generates random + WARNING. Cookie name is `praxis_op` (distinct from any future learner cookie).
|
||||
|
||||
#### TASK-03-03 — Login rate limiter (slowapi)
|
||||
- **Persona:** security-engineer
|
||||
- **File:** `server/auth/rate_limit.py` (new)
|
||||
- **Content:** `from slowapi import Limiter`. `limiter = Limiter(key_func=get_remote_address)` (in-memory backend, single-instance — D-041). `def rate_limit_login() -> callable` — returns a decorator `@limiter.limit("5/minute")` for the login route. 429 + `Retry-After` header on exceed. Document the hand-rolled counter fallback in comments (RESEARCH-v0.4 §2.5).
|
||||
- **Acceptance criteria:** 6th login attempt within 1 minute returns 429 with Retry-After. Rate limit is per-IP. Counter resets after 1 minute. R-AUTH-03 (in-memory lost on restart) documented as accepted pilot risk.
|
||||
|
||||
#### TASK-03-04 — current_operator dependency
|
||||
- **Persona:** security-engineer
|
||||
- **File:** `server/auth/dependencies.py` (new)
|
||||
- **Content:** `async def current_operator(request: Request) -> Operator` — reads `request.session.get("operator_id")`; if missing → raise `HTTPException(401, "not authenticated")`; fetches operator from PgStore by id; if not found or `is_active=False` → 401 + clear session; returns `Operator` dataclass (id, username, display_name, role). This is the server-side auth enforcement (D-057) — every `/api/operator/*` protected route uses `Depends(current_operator)`.
|
||||
- **Acceptance criteria:** No cookie → 401. Invalid/expired cookie → 401. Valid cookie + active operator → returns Operator. Valid cookie + inactive operator → 401 + session cleared. The dependency never trusts the client (D-057).
|
||||
|
||||
#### TASK-03-05 — Auth route handlers (login, logout, me)
|
||||
- **Persona:** security-engineer
|
||||
- **File:** `server/auth/routes.py` (new)
|
||||
- **Content:** `APIRouter(prefix="/api/operator")` with:
|
||||
- `POST /login` — rate-limited (TASK-03-03). Body: `{username, password}`. Fetches operator from PgStore, `verify_password`, on success sets `request.session["operator_id"] = op.id`, updates `last_login_at`, returns `{operator: {id, username, display_name}}`. On failure → 401. If `needs_rehash` → rehash + update store.
|
||||
- `POST /logout` — `Depends(current_operator)` — clears `request.session`, returns `{ok: true}`. (Stateless — client also clears cookie; D-056.)
|
||||
- `GET /me` — `Depends(current_operator)` — returns `{operator: {id, username, display_name, role}}`. This is the React route guard endpoint (D-057).
|
||||
- Login + logout are outside the protected router (login is rate-limited, not auth-gated; logout is auth-gated but on the same router).
|
||||
- **Acceptance criteria:** Login with correct creds → 200 + cookie set. Login with wrong creds → 401 + no cookie. 6th attempt → 429. `/me` with valid cookie → 200. `/me` without cookie → 401. `/logout` clears session.
|
||||
|
||||
#### TASK-03-06 — Auth unit tests
|
||||
- **Persona:** security-engineer
|
||||
- **File:** `tests/test_auth.py` (new)
|
||||
- **Content:** Unit tests for passwords (hash/verify/rehash), cookie config (secure flag logic, warning on false), rate limiter (5/min threshold), current_operator dependency (401 cases, active/inactive), login/logout/me route handlers (with mocked PgStore). Tests do not require a real Postgres (mock PgStore).
|
||||
- **Acceptance criteria:** All tests pass with mocked PgStore. Coverage: password verify fail, rate limit, 401 on missing/invalid/expired cookie, 401 on inactive operator, rehash on login.

## SLICE-04: VC Issuer Key Migration (W2)
|
||||
|
||||
- **Goal:** Migrate the VC issuer key store from SQLite to Postgres. Refactor `issuer_keys.py` to an `IssuerKeyStore` protocol (both PraxisStore and PgStore implement it). Archive the v0.3 public key as `superseded` in Postgres. Generate a fresh v0.4 keypair. Update verification to use PgStore.
|
||||
- **REQ-IDs covered:** REQ-MT-01 (issuer_keys in Postgres — partial)
|
||||
- **Wave:** 2
|
||||
- **Dependencies:** SLICE-01 (issuer_keys table + PgStore issuer key methods)
|
||||
- **Primary persona:** security-engineer
|
||||
- **Supporting personas:** data-engineer (PgStore issuer key implementation)
|
||||
|
||||
### Tasks
|
||||
|
||||
#### TASK-04-01 — IssuerKeyStore protocol/ABC
|
||||
- **Persona:** security-engineer
|
||||
- **File:** `server/vc/issuer_keys.py` (refactor)
|
||||
- **Content:** Define `class IssuerKeyStore(Protocol)` with methods: `init_issuer_key(key_id, public_key, private_key_enc)`, `get_active_signing_key_row() -> dict | None`, `get_public_key_row(key_id) -> dict | None`, `set_issuer_key_superseded(key_id)`. Refactor existing functions (`init_issuer_key`, `get_active_signing_key`, `get_public_key_for_verification`, `rotate_key`) to accept `IssuerKeyStore` instead of `PraxisStore`. The existing `PraxisStore` already implements these methods (duck-typing) — the protocol formalizes the interface. Keep `_encrypt_private_key`, `_decrypt_private_key`, `_verification_method`, `KeyPair` unchanged. R-VC-MIG-03 mitigation: both stores implement the same protocol.
|
||||
- **Acceptance criteria:** `PraxisStore` passes `isinstance(store, IssuerKeyStore)` (or structural check). `PgStore` passes the same. Existing v0.3 tests still pass (PraxisStore path unchanged). No breaking change to function signatures beyond the type annotation.
|
||||
|
||||
#### TASK-04-02 — PgStore issuer key methods
|
||||
- **Persona:** data-engineer
|
||||
- **File:** `db/pg_store.py` (extend — SLICE-01 stubs, now full implementation)
|
||||
- **Content:** Full implementation of the 4 IssuerKeyStore methods using asyncpg. `init_issuer_key` → INSERT with `gen_random_uuid()` or provided key_id. `get_active_signing_key_row` → SELECT WHERE status='active' ORDER BY created_at DESC LIMIT 1. `get_public_key_row` → SELECT WHERE id=$1 (queries by id, not status — **this is the superseded key fallback** per D-051). `set_issuer_key_superseded` → UPDATE status='superseded' WHERE id=$1. `private_key_enc` is BYTEA in Postgres (vs BLOB in SQLite).
|
||||
- **Acceptance criteria:** All 4 methods work with real Postgres. `get_public_key_row` finds both active AND superseded keys by id (R-VC-MIG-01 mitigation — verification fallback). Round-trip: init → get_active → set_superseded → get_public_key(superseded id) still returns the row.
|
||||
|
||||
#### TASK-04-03 — VC key migration script
|
||||
- **Persona:** security-engineer
|
||||
- **File:** `server/vc/migrate_keys.py` (new)
|
||||
- **Content:** `async def migrate_issuer_keys(sqlite_store: PraxisStore, pg_store: PgStore, root_key: bytes) -> dict` — the one-time migration procedure (D-051):
|
||||
1. Read v0.3 active public key from SQLite `issuer_keys` (status='active').
|
||||
2. Insert that public key into Postgres `issuer_keys` with status='superseded' (private key NOT migrated — only public key archived for verification).
|
||||
3. Generate a fresh Ed25519 keypair in Postgres `issuer_keys` with status='active' (encrypted at rest with root key — same nacl.SecretBox pattern).
|
||||
4. Return `{archived_key_id, new_key_id}`.
|
||||
Idempotent: if Postgres already has an active key, skip steps 2-3 (no-op). If Postgres has a superseded key matching the v0.3 key_id, skip step 2.
|
||||
**R-VC-MIG-01 mitigation: archive the v0.3 public key BEFORE activating the new key.** The script does step 2 before step 3.
|
||||
- **Acceptance criteria:** Running the migration on a fresh Postgres: v0.3 public key appears as superseded, fresh key appears as active. Re-running is a no-op. v0.3 VCs still verify against the archived (superseded) public key.
|
||||
|
||||
#### TASK-04-04 — Verification endpoint store swap
|
||||
- **Persona:** security-engineer
|
||||
- **File:** `server/vc/verification.py` (extend)
|
||||
- **Content:** `verify_credential` currently takes `PraxisStore`. Refactor to accept either `PraxisStore` (v0.3 SQLite) or `PgStore` (v0.4 Postgres) via the IssuerKeyStore protocol for key lookup. For credential lookup: try Postgres `issued_credentials` first; if not found, fall back to SQLite `issued_credentials` (v0.3 credentials remain in SQLite — no data migration per D-051 "no re-issuance"). The key lookup always uses the passed store. Add a `store` parameter that implements both credential + key lookup. **The __main__.py wiring (passing PgStore) is in SLICE-06.**
|
||||
- **Acceptance criteria:** `verify_credential` works with PraxisStore (v0.3 path — existing tests pass). `verify_credential` works with PgStore (v0.4 path — new test). v0.3 credential in SQLite + v0.3 key archived as superseded in Postgres → verifies ✓.
|
||||
|
||||
#### TASK-04-05 — VC migration unit tests
|
||||
- **Persona:** security-engineer
|
||||
- **File:** `tests/test_vc_migration.py` (new)
|
||||
- **Content:** Tests with mocked stores:
|
||||
- Migration script: v0.3 key archived as superseded, fresh key active. Idempotent re-run.
|
||||
- Verification with PgStore: v0.4 VC (active key) verifies ✓. v0.3 VC (superseded key) verifies ✓ (R-VC-MIG-01 — the critical test).
|
||||
- Verification fallback: `get_public_key_row` finds superseded key by id.
|
||||
- Root key handling: v0.4 active key encrypted with v0.4 root key (R-VC-MIG-02 — v0.3 root key kept for v0.3 SQLite path).
|
||||
- **Acceptance criteria:** All tests pass. R-VC-MIG-01 explicitly tested: a v0.3 VC verifies against a Postgres store with the v0.3 public key archived as superseded.
|
||||

|
||||
|
||||
## SLICE-05: Operator Bootstrap CLI (W2)
|
||||
|
||||
- **Goal:** Implement `scripts/create-operator.py` — the first-run CLI that creates the initial operator from env-provided credentials (D-052).
|
||||
- **REQ-IDs covered:** REQ-AUTH-01 (operator account provisioning — partial)
|
||||
- **Wave:** 2
|
||||
- **Dependencies:** SLICE-01 (PgStore + operators table), SLICE-03 (argon2id hashing — TASK-03-01)
|
||||
- **Primary persona:** devops-engineer
|
||||
- **Supporting personas:** security-engineer (argon2id hashing pattern)
|
||||
|
||||
### Tasks
|
||||
|
||||
#### TASK-05-01 — scripts/create-operator.py
|
||||
- **Persona:** devops-engineer
|
||||
- **File:** `scripts/create-operator.py` (new)
|
||||
- **Content:** CLI script that:
|
||||
1. Reads `PRAXIS_BOOTSTRAP_OPERATOR_USER` + `PRAXIS_BOOTSTRAP_OPERATOR_PASS` from env. If either missing → print error + exit 1 (R-BOOT-02).
|
||||
2. Reads `PRAXIS_PG_DSN` from env. If missing → print error + exit 1.
|
||||
3. Creates asyncpg pool, applies migrations (ensure schema exists).
|
||||
4. Hashes password with `argon2.PasswordHasher().hash(password)` (same defaults as TASK-03-01).
|
||||
5. `INSERT INTO operators (username, password_hash, display_name) VALUES ($1, $2, $3) ON CONFLICT (username) DO NOTHING` (idempotent — D-052).
|
||||
6. Prints `created` or `already exists` + exits 0.
|
||||
7. `--update` flag: `ON CONFLICT (username) DO UPDATE SET password_hash = excluded.password_hash` (force rehash — RESEARCH-v0.4 §open-questions #4).
|
||||
8. Retries on connection failure (3 attempts, 5s backoff — R-BOOT-01).
|
||||
- **Acceptance criteria:** Running with valid env vars creates the operator. Re-running prints "already exists" (no password update). `--update` flag rehashes + updates. Missing env var → clear error + exit 1. Connection failure → retries 3x then clear error.
|
||||
|
||||
#### TASK-05-02 — config.json secrets scope + .env.secrets template
|
||||
- **Persona:** devops-engineer
|
||||
- **File:** `.ciagent/config.json` (extend secrets.scopes), `.ciagent/.env.secrets.example` (new — template, not the real secrets)
|
||||
- **Content:** Add `operator` scope to `config.json` secrets.scopes: `{"name": "operator", "env_vars": ["PRAXIS_PG_PASSWORD", "PRAXIS_COOKIE_SECRET", "PRAXIS_BOOTSTRAP_OPERATOR_USER", "PRAXIS_BOOTSTRAP_OPERATOR_PASS", "PRAXIS_VC_ISSUER_KEY"]}`. Create `.env.secrets.example` documenting all operator secret vars (committed; the real `.env.secrets` is gitignored).
|
||||
- **Acceptance criteria:** `config.json` validates. New scope appears in secrets.scopes. `.env.secrets.example` is committed (no real secrets). `.env.secrets` is gitignored (verified).
|
||||
|
||||
#### TASK-05-03 — Bootstrap CLI test
|
||||
- **Persona:** devops-engineer
|
||||
- **File:** `tests/test_create_operator.py` (new)
|
||||
- **Content:** Test with mocked PgStore: create operator → verify exists in store. Re-run → "already exists" (no password update). `--update` → password updated. Missing env → exit 1. Verify password is argon2id hashed (not plaintext).
|
||||
- **Acceptance criteria:** All tests pass with mocked PgStore. Password hash starts with `$argon2id$` (not plaintext). Idempotent on re-run.
|
||||
|
||||
---
|
||||
|
||||
## SLICE-06: P1 Integration (W3)
|
||||
|
||||
- **Goal:** Wire all P1 modules into `server/__main__.py`: lifespan pool, SessionMiddleware, auth routes, verification store swap. Run end-to-end P1 integration tests including the critical VC migration e2e test (R-VC-MIG-01).
|
||||
- **REQ-IDs covered:** REQ-MT-01 (full integration), REQ-AUTH-01 (auth wired), REQ-NFR-AUTH-01 (auth NFRs verified end-to-end), REQ-NFR-MT-01 (Postgres + learner service coexist)
|
||||
- **Wave:** 3
|
||||
- **Dependencies:** SLICE-03 (auth module), SLICE-04 (VC migration), SLICE-05 (bootstrap CLI)
|
||||
- **Primary persona:** backend-engineer
|
||||
- **Supporting personas:** lead-developer (integration orchestration), security-engineer (VC migration e2e)
|
||||
|
||||
### Tasks
|
||||
|
||||
#### TASK-06-01 — __main__.py — mount SessionMiddleware + lifespan pool
|
||||
- **Persona:** backend-engineer
|
||||
- **File:** `server/__main__.py` (extend)
|
||||
- **Content:** Add `SessionMiddleware` with kwargs from `server.auth.cookies.get_session_middleware_kwargs()`. Add the lifespan context manager (from TASK-01-03) to the FastAPI app. The lifespan creates the asyncpg pool + runs pg_migrate. Create a `PgStore(pool)` instance on `app.state.pg_store` when pool is available. Keep the existing `_store` (PraxisStore/SQLite) for learner state. `SessionMiddleware` is added BEFORE CORS middleware (middleware order: outermost first — SessionMiddleware should be outermost to sign cookies before CORS headers).
|
||||
- **Acceptance criteria:** With Postgres: `app.state.pg_pool` + `app.state.pg_store` populated on startup. Without Postgres: server starts with WARNING, voice loop works, auth routes return 503 (service unavailable — no operator store). Cookie `praxis_op` is signed (itsdangerous).
|
||||
|
||||
#### TASK-06-02 — __main__.py — mount auth routes
|
||||
- **Persona:** backend-engineer
|
||||
- **File:** `server/__main__.py` (extend)
|
||||
- **Content:** `from server.auth.routes import router as auth_router`. `app.include_router(auth_router)` — mounts `/api/operator/login`, `/api/operator/logout`, `/api/operator/me`. The auth routes use `app.state.pg_store` for operator lookup. If `pg_store` is None (no Postgres), auth routes return 503. Register auth routes BEFORE the StaticFiles mount (routes-before-static-mount constraint — carry-forward from v0.2).
|
||||
- **Acceptance criteria:** `POST /api/operator/login` with valid creds → 200 + cookie. `GET /api/operator/me` with cookie → 200. Without cookie → 401. Routes are matched before StaticFiles (verified: `/api/operator/login` returns JSON, not index.html).
|
||||
|
||||
#### TASK-06-03 — __main__.py — swap verification endpoint to PgStore
|
||||
- **Persona:** backend-engineer
|
||||
- **File:** `server/__main__.py` (extend)
|
||||
- **Content:** Update the existing `/vc/verify/{credential_id}` route: if `app.state.pg_store` is available, use it for issuer key lookup (PgStore) + credential lookup (try Postgres first, fall back to SQLite for v0.3 credentials per TASK-04-04). If `pg_store` is None (no Postgres), fall back to the existing PraxisStore path (v0.3 compat). Run the VC key migration on first boot: if PgStore has no active issuer key, call `migrate_issuer_keys(_store, pg_store, root_key)` (from TASK-04-03).
|
||||
- **Acceptance criteria:** With Postgres: `/vc/verify/<v0.3-credential-id>` → verifies against archived superseded key in Postgres ✓. `/vc/verify/<v0.4-credential-id>` → verifies against active key in Postgres ✓. Without Postgres: `/vc/verify` falls back to SQLite (v0.3 compat). VC key migration runs once on first boot (idempotent).
|
||||
|
||||
#### TASK-06-04 — P1 integration test (auth end-to-end)
|
||||
- **Persona:** backend-engineer
|
||||
- **File:** `tests/test_p1_auth_integration.py` (new — requires Postgres, skip if no DSN)
|
||||
- **Content:** End-to-end auth flow: create operator via bootstrap CLI → POST /login → GET /me → POST /logout → GET /me (401). Test rate limiting (6th attempt → 429). Test cookie attributes (httpOnly, SameSite=Strict, secure per PRAXIS_COOKIE_SECURE). Test 8h expiry (mock time or check max_age). Test that learner voice loop (`/health`, `/pipecat/webrtc`) is unaffected by auth (REQ-NFR-MT-01 — Postgres + learner service coexist).
|
||||
- **Acceptance criteria:** Full auth flow works. Rate limit enforces 5/min. Cookie attributes match D-041/D-056. Learner voice loop unaffected (health check passes, WebRTC offer accepted — Postgres presence doesn't destabilize).
|
||||
|
||||
#### TASK-06-05 — VC migration e2e test (R-VC-MIG-01 — critical)
|
||||
- **Persona:** security-engineer
|
||||
- **File:** `tests/test_p1_vc_migration_e2e.py` (new — requires Postgres, skip if no DSN)
|
||||
- **Content:** The critical R-VC-MIG-01 test:
|
||||
1. Seed SQLite with a v0.3 issuer key + a v0.3-issued credential (or use existing test fixtures).
|
||||
2. Start the server with Postgres → migration runs automatically.
|
||||
3. Verify Postgres has: 1 superseded key (v0.3 public key) + 1 active key (v0.4 fresh keypair).
|
||||
4. `GET /vc/verify/<v0.3-credential-id>` → `valid: true` (verifies against archived superseded key — **R-VC-MIG-01 PASS**).
|
||||
5. Issue a new v0.4 credential (via mastery flow or test helper) → `GET /vc/verify/<v0.4-credential-id>` → `valid: true`.
|
||||
6. Tamper v0.3 credential → verify fails.
|
||||
7. Re-run server → migration is no-op (idempotent).
|
||||
- **Acceptance criteria:** v0.3 VC verifies against Postgres store with archived superseded key (R-VC-MIG-01 explicitly verified). v0.4 VC verifies against active key. Migration is idempotent. Tamper detection works.

## SLICE-07: Cohort Aggregation Pipeline (W1)
|
||||
|
||||
- **Goal:** Implement the cohort aggregation pipeline: on-session-end async fire-and-forget hook, nightly reconciliation job at 03:00 CT, k-anonymity ≥ 10 write-time suppression. Chain the hook into `session_recorder.py` after the mastery flow.
|
||||
- **REQ-IDs covered:** REQ-MT-02 (pipeline completion), REQ-NFR-DASH-02 (freshness ≤ 24h)
|
||||
- **Wave:** 1
|
||||
- **Dependencies:** P1 SLICE-01 (cohort_aggregates table + PgStore upsert method)
|
||||
- **Primary persona:** backend-engineer
|
||||
- **Supporting personas:** data-engineer (k-anonymity suppression SQL), security-engineer (learner_ref opaque — no PII)
|
||||
|
||||
### Tasks
|
||||
|
||||
#### TASK-07-01 — Aggregation logic + k-anonymity suppression
|
||||
- **Persona:** backend-engineer
|
||||
- **File:** `server/cohort/aggregator.py` (new)
|
||||
- **Supporting:** data-engineer (suppression SQL)
|
||||
- **Content:** `async def aggregate_session(pg_store: PgStore, session_outcome: dict) -> None` — computes k-anonymized aggregates for the affected `(path, metric, window_start)` bins and upserts to `cohort_aggregates`. The `session_outcome` dict contains: learner_ref (opaque string — D-031), path, scenario_id, outcome (pass/fail), rubric_scores, failure_mode, branch_path, timestamp.
|
||||
- Metrics computed: `sessions_count`, `active_learners_count`, `gate_open_rate`, `median_mastery_score`, `failure_mode_frequency`, `rubric_criterion_means`, `week_distribution`.
|
||||
- **k-anonymity suppression (D-034, REQ-NFR-DASH-01):** `COUNT(DISTINCT learner_ref) >= 10` check per cell. If < 10 → `cell_suppressed=TRUE`, `value=NULL`. Suppression is at write time (auditable — RESEARCH-v0.4 §3.1).
|
||||
- **Idempotent upsert:** `ON CONFLICT (path, metric, window_start) DO UPDATE SET value=excluded.value, cell_count=excluded.cell_count, cell_suppressed=excluded.cell_suppressed, updated_at=now()`.
|
||||
- **No raw learner PII in Postgres** (D-031): only aggregates + opaque `learner_ref` for distinct counting.
|
||||
- **7-day rolling window:** `window_start = today::date - 6`, `window_end = today::date`.
|
||||
- Pre-defined 2-D views only (path × week, path × outcome) — no arbitrary filters (R-DASH-02 mitigation).
|
||||
- **Acceptance criteria:** Aggregate upsert is idempotent (re-run produces same result). Cells with < 10 distinct learners are suppressed (cell_suppressed=TRUE, value=NULL). No raw PII in Postgres (only aggregates + opaque learner_ref). 7-day window computed correctly.
|
||||
|
||||
#### TASK-07-02 — On-session-end async hook
|
||||
- **Persona:** backend-engineer
|
||||
- **File:** `server/cohort/hook.py` (new)
|
||||
- **Content:** `async def on_session_end(pg_store: PgStore, session_outcome: dict) -> None` — calls `aggregator.aggregate_session`. Designed to be chained as an `asyncio.create_task` (fire-and-forget — D-054). Failures log + nightly job reconciles (no exception propagation to the caller). The hook is non-blocking — the session-end response returns immediately. If `pg_store` is None (no Postgres), no-op + log WARNING.
|
||||
- **Acceptance criteria:** Hook is non-blocking (caller returns immediately). Hook failure logs but does not raise. No-Postgres → no-op + WARNING. Hook is idempotent (re-running with same session_outcome produces same aggregate).
|
||||
|
||||
#### TASK-07-03 — Nightly reconciliation job
|
||||
- **Persona:** backend-engineer
|
||||
- **File:** `server/cohort/nightly.py` (new)
|
||||
- **Content:** `class NightlyScheduler` — in-process asyncio scheduler (no APScheduler — RESEARCH-v0.4 §3.4). `async def start(self, pg_store)` — loops: compute seconds until next 03:00 CT → `asyncio.sleep(seconds)` → `await self._reconcile(pg_store)` → repeat. `async def _reconcile(self, pg_store)` — recomputes all 7-day windows for all paths (idempotent upsert). If the service restarts, the scheduler resumes on startup (computes next 03:00). Failures log + retry next night (R-DASH-04). The reconciliation guarantees REQ-NFR-DASH-02 (freshness ≤ 24h — the nightly job runs at least once/day).
|
||||
- **Acceptance criteria:** Scheduler computes correct seconds until 03:00 CT. Reconciliation recomputes all windows (idempotent). Scheduler resumes after restart. Job failure logs + retries next night. Max staleness = 24h (nightly job + on-session-end hook — REQ-NFR-DASH-02).
|
||||
|
||||
#### TASK-07-04 — Chain aggregation hook into session_recorder.py
|
||||
- **Persona:** backend-engineer
|
||||
- **File:** `server/session_recorder.py` (extend)
|
||||
- **Content:** After the mastery flow (line ~143, `asyncio.create_task(self._run_mastery_flow_guarded(mastery_deps))`), chain the aggregation hook: `asyncio.create_task(self._run_cohort_aggregation(pg_store, session_outcome))`. The `session_outcome` dict is built from the mastery result (scenario_id, path, outcome, rubric_scores, failure_mode, branch_path, learner_ref=self.learner_id). The hook is fire-and-forget (D-054). If `pg_store` is None (no Postgres), skip. The hook runs in parallel with the mastery flow (aggregation only needs the session outcome + rubric scores, which are available after the session ends — it does not need to wait for mastery completion). **Off the voice path (C-8, D-054).**
|
||||
- **Acceptance criteria:** Aggregation hook fires after session end. Voice loop latency unaffected (hook is async, non-blocking). Hook runs in parallel with mastery flow. No-Postgres → skip. session_recorder.py changes are backward-compatible (existing mastery flow unchanged).
|
||||
|
||||
#### TASK-07-05 — Aggregation unit tests
|
||||
- **Persona:** backend-engineer
|
||||
- **File:** `tests/test_cohort_aggregation.py` (new)
|
||||
- **Content:** Tests with mocked PgStore:
|
||||
- k-anonymity suppression: 9 learners → cell_suppressed=TRUE, value=NULL. 10 learners → cell_suppressed=FALSE, value=computed. 11 learners → not suppressed.
|
||||
- Idempotent upsert: same session_outcome twice → same aggregate.
|
||||
- 7-day window computation: window_start/window_end correct.
|
||||
- Multiple metrics: sessions_count, active_learners_count, gate_open_rate, etc.
|
||||
- No PII: only aggregates + opaque learner_ref in upsert calls.
|
||||
- **Acceptance criteria:** k-anon threshold exactly at 10 (9 suppressed, 10 not). Idempotent. All metrics computed correctly. No PII in any upsert call.
|
||||
|
||||
#### TASK-07-06 — Nightly job + hook integration test
|
||||
- **Persona:** backend-engineer
|
||||
- **File:** `tests/test_cohort_nightly.py` (new)
|
||||
- **Content:** Tests with mocked PgStore:
|
||||
- Scheduler computes correct seconds until 03:00 CT (mock datetime).
|
||||
- Reconciliation recomputes all windows (verify upsert calls for all paths × metrics).
|
||||
- Hook failure → log + nightly job reconciles (simulate hook failure, run nightly, verify aggregate is correct).
|
||||
- R-DASH-04: nightly job failure → logs + retries next night (mock failure, verify scheduler continues).
|
||||
- **Acceptance criteria:** Scheduler timing correct. Reconciliation covers all paths. Hook failure + nightly reconciliation = correct final state. Nightly failure doesn't crash the scheduler.

## SLICE-08: Operator API Cohort Endpoints (W1)
|
||||
|
||||
- **Goal:** Implement the 4 auth-gated operator API endpoints for the cohort dashboard: practice volume, mastery progression, failure patterns, and credential management.
|
||||
- **REQ-IDs covered:** REQ-DASH-01 (API layer — partial), REQ-NFR-DASH-01 (k-anon display — partial)
|
||||
- **Wave:** 1
|
||||
- **Dependencies:** P1 SLICE-03 (current_operator dependency), P1 SLICE-01 (PgStore cohort_aggregates read)
|
||||
- **Primary persona:** backend-engineer
|
||||
- **Supporting personas:** data-engineer (k-anon query optimization)
|
||||
|
||||
### Tasks
|
||||
|
||||
#### TASK-08-01 — GET /api/operator/cohort (practice volume)
|
||||
- **Persona:** backend-engineer
|
||||
- **File:** `server/operator/cohort.py` (new)
|
||||
- **Content:** `APIRouter` endpoint `GET /api/operator/cohort` with `dependencies=[Depends(current_operator)]` (D-057). Queries `cohort_aggregates` for practice volume metrics: sessions/day per path, total sessions in window, active learners (suppressed if < 10). Returns JSON: `{views: [{path, metrics: [{metric, window_start, window_end, value, cell_count, cell_suppressed, updated_at}]}], last_updated: "2026-08-04T03:00:00Z"}`. Suppressed cells have `value: null, cell_suppressed: true` — the frontend renders "— (<10 learners)" (D-053). No per-learner drill-down (R-DASH-02).
|
||||
- **Acceptance criteria:** Auth-gated (401 without cookie). Returns k-anonymized data. Suppressed cells have value=null. `last_updated` = max(updated_at) across returned rows (freshness indicator — REQ-NFR-DASH-02). No per-learner data.
|
||||
|
||||
#### TASK-08-02 — GET /api/operator/mastery (mastery progression)
|
||||
- **Persona:** backend-engineer
|
||||
- **File:** `server/operator/mastery.py` (new)
|
||||
- **Content:** `GET /api/operator/mastery` — auth-gated. Returns mastery progression metrics: % learners at each week (1-6), gate-open rate, median mastery_score, rubric criterion mean scores. Same JSON shape as TASK-08-01. All cells k-anonymized (suppressed if < 10).
|
||||
- **Acceptance criteria:** Auth-gated. Returns week distribution + gate-open rate + rubric criterion means. Suppressed cells have value=null. No per-learner data.
|
||||
|
||||
#### TASK-08-03 — GET /api/operator/failure-patterns
|
||||
- **Persona:** backend-engineer
|
||||
- **File:** `server/operator/failure_patterns.py` (new)
|
||||
- **Content:** `GET /api/operator/failure-patterns` — auth-gated. Returns failure pattern metrics: top failure_modes by frequency, rubric criteria with mean < 3.0 (weak-spots), branch outcome distribution (escalate vs accept). Same JSON shape. All k-anonymized.
|
||||
- **Acceptance criteria:** Auth-gated. Returns failure_mode frequency + weak criteria + branch distribution. Suppressed cells have value=null. No per-learner data.
|
||||
|
||||
#### TASK-08-04 — GET/POST /api/operator/credentials (VC management)
|
||||
- **Persona:** backend-engineer
|
||||
- **File:** `server/operator/credentials.py` (new)
|
||||
- **Content:** `GET /api/operator/credentials` — auth-gated. Lists issued VCs from Postgres `issued_credentials` (operator's issuance log). Returns `[{id, learner_ref, vc_type, status, issued_at, revoked_at}]`. `POST /api/operator/credentials/{id}/revoke` — auth-gated. Revokes a VC (sets status='revoked', revoked_at=now()). Updates the Bitstring Status List. This is the operator-side credential management (D-057 — VC issuance endpoints are auth-gated).
|
||||
- **Acceptance criteria:** Auth-gated. GET returns credential list (no PII beyond what the credential asserts — D-043). POST revoke → credential status='revoked'. Revoked credential fails verification (`GET /vc/verify/<id>` → valid: false, status: revoked).
|
||||
|
||||
#### TASK-08-05 — Endpoint unit tests
|
||||
- **Persona:** backend-engineer
|
||||
- **File:** `tests/test_operator_endpoints.py` (new)
|
||||
- **Content:** Tests with mocked PgStore + mocked current_operator:
|
||||
- All 4 endpoints return 401 without cookie.
|
||||
- All 4 endpoints return 200 with valid cookie.
|
||||
- Suppressed cells (cell_suppressed=TRUE) have value=null in response.
|
||||
- `last_updated` is the max(updated_at) across rows.
|
||||
- Credential revoke → status='revoked' in store + verification fails.
|
||||
- No per-learner data in any response (R-DASH-02).
|
||||
- **Acceptance criteria:** All endpoints auth-gated. Suppressed cells displayed correctly. Credential revoke works. No per-learner drill-down possible.
|
||||

|
||||
|
||||
## SLICE-09: React Cohort Dashboard + Router (W1)
|
||||
|
||||
- **Goal:** Implement the React cohort dashboard UI: React Router for `/operator/*` routes, login form, dashboard with 3 k-anonymized views, inline SVG sparklines, auth gate. The SPA fallback in `__main__.py` is in SLICE-10 (integration).
|
||||
- **REQ-IDs covered:** REQ-DASH-01 (UI layer — partial), REQ-NFR-DASH-01 (display suppressed cells — partial)
|
||||
- **Wave:** 1
|
||||
- **Dependencies:** P1 SLICE-03 (auth API contract: POST /login, GET /me), SLICE-08 (API contract: cohort/mastery/failure-patterns response shapes — implements against contract, not live API)
|
||||
- **Primary persona:** frontend-engineer
|
||||
- **Supporting personas:** backend-engineer (SPA fallback in SLICE-10, API contract consultation)
|
||||
|
||||
### Tasks
|
||||
|
||||
#### TASK-09-01 — Add react-router-dom to client/package.json
|
||||
- **Persona:** frontend-engineer
|
||||
- **File:** `client/package.json` (extend)
|
||||
- **Content:** Add `react-router-dom@^7` to dependencies. Run `npm install`. No chart library (inline SVG sparklines — zero deps, RESEARCH-v0.4 §4.3).
|
||||
- **Acceptance criteria:** `npm install` succeeds. `npm run build` succeeds. `react-router-dom` in `node_modules`. Bundle size increase is reasonable (< 20KB for react-router-dom).
|
||||
|
||||
#### TASK-09-02 — BrowserRouter wrapper + route switch in App.tsx
|
||||
- **Persona:** frontend-engineer
|
||||
- **File:** `client/src/main.tsx` (extend), `client/src/App.tsx` (extend)
|
||||
- **Content:** Wrap `App` in `<BrowserRouter>`. In `App.tsx`, add `<Routes>`:
|
||||
- `/` → existing voice session UI (start→live→debrief — unchanged)
|
||||
- `/operator/login` → `Login` component
|
||||
- `/operator/dashboard` → `Dashboard` component (auth-gated)
|
||||
- `*` (catch-all) → voice session UI (fallback for unknown routes — SPA fallback)
|
||||
- R-DASH-05 mitigation: the existing voice UI at `/` is unchanged. The catch-all route serves the voice UI, not a 404.
|
||||
- **Acceptance criteria:** Voice UI at `/` works exactly as before (R-DASH-05). `/operator/login` renders login form. `/operator/dashboard` renders dashboard (or redirects to login). `npm run build` succeeds. No regressions in voice UI.
|
||||
|
||||
#### TASK-09-03 — Login form component
|
||||
- **Persona:** frontend-engineer
|
||||
- **File:** `client/src/operator/Login.tsx` (new)
|
||||
- **Content:** Login form: username + password fields + submit button. `POST /api/operator/login` on submit. On success → navigate to `/operator/dashboard`. On failure → show error. On 429 → show "Too many attempts, try again in a minute." Minimal CSS (reuse App.css patterns — no Tailwind/bootstrap). Form is accessible (label associations, keyboard navigation).
|
||||
- **Acceptance criteria:** Login form renders. Successful login navigates to dashboard. Failed login shows error. Rate limit (429) shows retry message. Form is keyboard-accessible.
|
||||
|
||||
#### TASK-09-04 — Dashboard shell + auth gate
|
||||
- **Persona:** frontend-engineer
|
||||
- **File:** `client/src/operator/Dashboard.tsx` (new)
|
||||
- **Content:** Dashboard shell: on mount, `GET /api/operator/me` → if 401, redirect to `/operator/login` (D-057 — React route guard, UX only). If 200, render dashboard with: operator name in header, 3 view tabs (Practice Volume, Mastery Progression, Failure Patterns), freshness indicator ("Last updated: Xh ago" from `last_updated` in API response — REQ-NFR-DASH-02), logout button (POST /api/operator/logout → redirect to login). View content fetched from respective `/api/operator/<view>` endpoints.
|
||||
- **Acceptance criteria:** Auth gate redirects to login on 401. Dashboard renders operator name. 3 view tabs switch. Freshness indicator shows "Last updated: Xh ago". Logout redirects to login. No PII displayed (only k-anonymized aggregates — D-031).
|
||||
|
||||
#### TASK-09-05 — Inline SVG sparkline component
|
||||
- **Persona:** frontend-engineer
|
||||
- **File:** `client/src/operator/Sparkline.tsx` (new)
|
||||
- **Content:** `<Sparkline data={number[]} width={60} height={20} />` — renders an SVG polyline from the data array. ~50 LOC, zero deps (RESEARCH-v0.4 §4.3). Handles edge cases: empty data (renders nothing), single point (renders a dot), all-same values (renders a flat line). Color: stroke=currentColor (inherits from parent). No axes, no tooltips (sparklines are compact trend indicators, not full charts).
|
||||
- **Acceptance criteria:** Renders SVG polyline for 7-30 data points. Empty data → no render. Single point → dot. All-same → flat line. No external deps. ~50 LOC.
|
||||
|
||||
#### TASK-09-06 — 3 dashboard view components
|
||||
- **Persona:** frontend-engineer
|
||||
- **Files:** `client/src/operator/views/PracticeVolume.tsx` (new), `client/src/operator/views/MasteryProgression.tsx` (new), `client/src/operator/views/FailurePatterns.tsx` (new)
|
||||
- **Content:** Each view: fetches its `/api/operator/<view>` endpoint, renders read-only tables + sparklines.
|
||||
- **PracticeVolume:** sessions/day per path (table + sparkline), total sessions, active learners. Suppressed cells → "— (<10 learners)" (REQ-NFR-DASH-01 display).
|
||||
- **MasteryProgression:** % learners at each week (bar-like table), gate-open rate, median mastery_score, rubric criterion means (table + sparkline). Suppressed cells → "— (<10 learners)".
|
||||
- **FailurePatterns:** top failure_modes by frequency (sorted table), rubric criteria with mean < 3.0 (highlighted as weak-spots), branch outcome distribution. Suppressed cells → "— (<10 learners)".
|
||||
- All views: loading state, error state, no-data state. Read-only (no filters, no drill-down — R-DASH-02).
|
||||
- **Acceptance criteria:** Each view fetches + renders k-anonymized data. Suppressed cells display "— (<10 learners)". Tables are read-only. Sparklines render in table rows. Loading/error/no-data states handled. No per-learner drill-down.
|
||||
|
||||
#### TASK-09-07 — Dashboard unit tests
|
||||
- **Persona:** frontend-engineer
|
||||
- **File:** `client/src/operator/__tests__/Dashboard.test.tsx` (new — or co-located per project convention)
|
||||
- **Content:** Tests:
|
||||
- Auth gate: 401 on /me → redirect to /operator/login.
|
||||
- Login form: submit → POST /login → navigate to dashboard.
|
||||
- Suppressed cell display: cell_suppressed=true → "— (<10 learners)" rendered.
|
||||
- Sparkline: renders SVG polyline for given data.
|
||||
- Freshness indicator: "Last updated: Xh ago" computed from last_updated.
|
||||
- No PII: only aggregate values in rendered DOM.
|
||||
- **Acceptance criteria:** All tests pass. Auth gate works. Suppressed cells display correctly. Sparkline renders. No PII in DOM.
|
||||

|
||||
|
||||
## SLICE-10: P2 Integration (W2)
|
||||
|
||||
- **Goal:** Wire P2 modules into `server/__main__.py`: SPA fallback catch-all route (before StaticFiles), operator API router mount (cohort/mastery/failure-patterns/credentials), nightly scheduler start. Run end-to-end aggregation→endpoint→dashboard integration tests.
|
||||
- **REQ-IDs covered:** REQ-DASH-01 (full integration), REQ-NFR-DASH-01 (k-anon e2e), REQ-NFR-DASH-02 (freshness e2e), REQ-MT-02 (pipeline e2e)
|
||||
- **Wave:** 2
|
||||
- **Dependencies:** SLICE-07 (aggregation pipeline), SLICE-08 (operator endpoints), SLICE-09 (React dashboard)
|
||||
- **Primary persona:** backend-engineer
|
||||
- **Supporting personas:** lead-developer (integration orchestration), frontend-engineer (SPA fallback verification)
|
||||
|
||||
### Tasks
|
||||
|
||||
#### TASK-10-01 — __main__.py — SPA fallback catch-all route
|
||||
- **Persona:** backend-engineer
|
||||
- **File:** `server/__main__.py` (extend)
|
||||
- **Content:** Add a catch-all route BEFORE the StaticFiles mount: `@app.get("/{path:path}")` that returns `FileResponse("client/dist/index.html")` for any path not matching an API route (`/health`, `/pipecat/*`, `/vc/*`, `/api/operator/*`). This is the SPA fallback for React Router `/operator/*` routes (R-DASH-03). **R-DASH-03 mitigation: the catch-all is BEFORE the StaticFiles mount, and the existing API routes are registered before the catch-all.** The StaticFiles mount remains for serving JS/CSS/assets (the catch-all only serves index.html for client-side routes). Test: `/` still serves the voice UI (index.html, which loads the voice app); `/operator/dashboard` serves index.html (React Router handles the route client-side); `/api/operator/cohort` still returns JSON (not index.html).
|
||||
- **Acceptance criteria:** `GET /` → index.html (voice UI loads). `GET /operator/dashboard` → index.html (React Router handles it). `GET /operator/login` → index.html. `GET /api/operator/cohort` → JSON (not index.html — API routes take precedence). `GET /health` → JSON. `GET /vc/verify/123` → JSON. `GET /static.js` → served by StaticFiles (not the catch-all). R-DASH-03 verified: voice UI at `/` unchanged.
|
||||
|
||||
#### TASK-10-02 — __main__.py — mount operator API router + nightly scheduler
|
||||
- **Persona:** backend-engineer
|
||||
- **File:** `server/__main__.py` (extend)
|
||||
- **Content:** `from server.operator.cohort import router as cohort_router`, `from server.operator.mastery import router as mastery_router`, `from server.operator.failure_patterns import router as failure_router`, `from server.operator.credentials import router as credentials_router`. `app.include_router(...)` for each. All use `prefix="/api/operator"` + `dependencies=[Depends(current_operator)]` (auth-gated — D-057). Mount BEFORE the SPA fallback catch-all. Start the nightly scheduler in the lifespan: `asyncio.create_task(nightly_scheduler.start(pg_store))` (if pg_store available). Cancel the scheduler task on shutdown.
|
||||
- **Acceptance criteria:** `GET /api/operator/cohort` with valid cookie → JSON. Without cookie → 401. Nightly scheduler starts on app startup (if Postgres). Scheduler cancelled on shutdown. API routes matched before SPA fallback.
|
||||
|
||||
#### TASK-10-03 — P2 integration test (aggregation → endpoint → response)
|
||||
- **Persona:** backend-engineer
|
||||
- **File:** `tests/test_p2_aggregation_integration.py` (new — requires Postgres, skip if no DSN)
|
||||
- **Content:** End-to-end:
|
||||
1. Seed 15 mock sessions (12 distinct learners — above k-anon threshold) for a path.
|
||||
2. Run the aggregation hook for each session → `cohort_aggregates` populated.
|
||||
3. `GET /api/operator/cohort` (with auth cookie) → returns practice volume with non-suppressed cells (12 ≥ 10).
|
||||
4. Seed 5 more sessions from 5 NEW distinct learners for a different path → `GET /api/operator/cohort` for that path → suppressed cells (5 < 10, value=null, cell_suppressed=true). REQ-NFR-DASH-01 verified.
|
||||
5. Run nightly reconciliation → all windows recomputed → `last_updated` updated.
|
||||
6. `GET /api/operator/mastery` → mastery progression data.
|
||||
7. `GET /api/operator/failure-patterns` → failure pattern data.
|
||||
8. Verify `last_updated` in response ≤ 24h old (REQ-NFR-DASH-02).
|
||||
- **Acceptance criteria:** k-anon threshold enforced (12 learners → not suppressed, 5 → suppressed). All 3 endpoints return k-anonymized data. Nightly reconciliation updates `last_updated`. Freshness ≤ 24h (REQ-NFR-DASH-02). No per-learner data in any response.
|
||||
|
||||
#### TASK-10-04 — P2 integration test (SPA fallback + voice UI coexist)
|
||||
- **Persona:** backend-engineer
|
||||
- **File:** `tests/test_p2_spa_fallback.py` (new)
|
||||
- **Content:** Tests against the running server (or TestClient):
|
||||
1. `GET /` → 200, `content-type: text/html`, contains `<div id="root">` (voice UI loads).
|
||||
2. `GET /operator/dashboard` → 200, `content-type: text/html`, contains `<div id="root">` (SPA fallback serves index.html).
|
||||
3. `GET /operator/login` → 200, `text/html` (SPA fallback).
|
||||
4. `GET /api/operator/cohort` → JSON (API route, not SPA fallback).
|
||||
5. `GET /health` → JSON (API route).
|
||||
6. `GET /pipecat/webrtc` → 405 (method not allowed — POST only, but route exists, not SPA fallback).
|
||||
7. `GET /vc/verify/nonexistent` → 404 (API route, not SPA fallback).
|
||||
8. `GET /assets/index.js` → served by StaticFiles (not SPA fallback).
|
||||
**R-DASH-03 verified: SPA fallback serves index.html for client-side routes; API routes + StaticFiles assets are unaffected.**
|
||||
- **Acceptance criteria:** All 8 assertions pass. R-DASH-03 verified: voice UI at `/` unchanged, operator routes serve index.html, API routes return JSON, assets served by StaticFiles.
|
||||
|
||||
#### TASK-10-05 — P2 verification matrix
|
||||
- **Persona:** lead-developer
|
||||
- **File:** `.ciagent/VERIFY-P2.md` (new — pre-verify checklist for the verify stage)
|
||||
- **Content:** REQ-ID → test mapping for P2. Confirm all P2 REQ-IDs (REQ-DASH-01, REQ-NFR-DASH-01, REQ-NFR-DASH-02, REQ-MT-02) have covering tests. List each test file + what it verifies. Cross-reference with P1 VERIFY (if any).
|
||||
- **Acceptance criteria:** Every P2 REQ-ID has at least one covering test listed. Matrix is complete (no gaps).
|
||||
|

|
||||
|
||||
# Final Phase (P3) — Review + Audit + Milestone Ship
|
||||
|
||||
**Branch:** `phase/03-final-review-ship` → merged to `milestone/v0.4-operator-tier` → merged to `main`
|
||||
**Ship:** `v0.1.9` (final patch = v0.4 milestone release)
|
||||
**REQ-IDs covered:** all v0.4 REQ-IDs (milestone-complete verification)
|
||||
|
||||
### Tasks (delegated to ciagent-review + ciagent-audit + ciagent-ship)
|
||||
|
||||
1. Run branch gate → create `phase/03-final-review-ship`
|
||||
2. `ciagent-review` — multi-persona review across P1 + P2; auto-apply P0 fixes, flag P1+
|
||||
- **Security-engineer review focus:** auth stack (argon2id, cookies, rate limit), VC key migration (R-VC-MIG-01), R-AUTH-01 (Secure cookie + no-TLS — config-driven flag documented in GRILL-v0.4.md)
|
||||
- **Data-engineer review focus:** k-anonymity suppression (write-time, ≥10 threshold), no PII in Postgres, no cross-DB joins
|
||||
- **Frontend-engineer review focus:** auth gate (UX-only, server is authority), suppressed cell display, SPA fallback (R-DASH-03)
|
||||
3. `ciagent-audit` — reconstruction test, file discipline, branch hygiene, commit discipline
|
||||
4. `ciagent-ship` — merge phase/03 → milestone/v0.4-operator-tier → main; tag v0.1.9; create release with full milestone summary
|
||||
5. Update REQUIREMENTS.md (all v0.4 REQ → complete), ROADMAP.md (v0.4 → complete; v0.5 = Live Assist)
|
||||
6. Commit: `docs(milestone): complete v0.4-operator-tier`
|
||||
7. Clear checkpoint

# Open Questions Deferred to EXECUTE
|
||||
|
||||
1. **v0.3 issued_credentials migration:** The verification endpoint needs to find v0.3 credentials (in SQLite) AND v0.4 credentials (in Postgres). SLICE-04 TASK-04-04 implements a try-Postgres-first-fall-back-to-SQLite approach. Alternative: migrate v0.3 credential rows to Postgres (data migration, not re-signing). The executor should choose the simpler approach — the fallback-to-SQLite is simpler (no data migration) but means the verification endpoint queries two stores. Confirm in SLICE-04/SLICE-06.
|
||||
|
||||
2. **SPA fallback implementation:** Catch-all route (`@app.get("/{path:path}")`) before StaticFiles, or a custom StaticFiles subclass that returns index.html for non-file paths? SLICE-10 TASK-10-01 uses the catch-all route (simpler). The executor should verify the catch-all doesn't shadow StaticFiles asset serving (JS/CSS files). The test in TASK-10-04 verifies this.
|
||||
|
||||
3. **Cohort aggregation `learner_ref` source:** The existing `HARDCODED_LEARNER_ID = "learner-1"` (db/store.py:29). For v0.4 (single learner), k-anonymity will suppress everything (1 < 10). This is expected at pilot scale (R-DASH-01). The aggregation pipeline groups by `learner_ref` so k-anon counts distinct learners. Multi-learner-per-device is deferred. Confirm the dashboard shows "— (suppressed, <10 learners)" for all cells in the single-learner pilot. The executor should seed test data with ≥10 mock learners to verify the non-suppressed path.
|
||||
|
||||
4. **Nightly scheduler timezone:** 03:00 CT (Central Time — Canada pilot is CT?). The scheduler uses `datetime.now()` with a timezone-aware approach. The executor should use `zoneinfo.ZoneInfo("America/Winnipeg")` or similar for CT. Confirm in SLICE-07 TASK-07-03.
|
||||
|
||||
5. **`create-operator.py` `--update` flag:** SLICE-05 TASK-05-01 includes a `--update` flag for force-rehash. The executor should decide if this is a positional arg or a `--update` flag. Keep it simple: `--update` flag.
|
||||
|
||||
6. **Cookie `path` scope:** RESEARCH-v0.4 §open-questions #5 recommends `path="/"` (cookie sent to all routes) so the React `/operator/*` routes can call `/api/operator/me` on mount. SLICE-03 TASK-03-02 uses `path="/"`. Confirm.
|
||||
|
||||
7. **Aggregation hook parallel vs sequential with mastery flow:** SLICE-07 TASK-07-04 chains the aggregation hook in parallel with the mastery flow (both are `asyncio.create_task`). The aggregation only needs the session outcome (available after session end), not the mastery scoring result. However, some metrics (rubric criterion means) need the rubric scores from the mastery flow. The executor should decide: chain the aggregation AFTER mastery completion (sequential) or run in parallel and have the nightly job fill in rubric-dependent metrics. Recommendation: run in parallel + nightly job reconciles rubric-dependent metrics (simpler, freshness ≤ 24h guaranteed by nightly).

@@ -14,9 +15,67 @@ Praxis is a voice-first, AI-tutored skill platform for learners in resource-cons
|
||||
|
||||
Build a voice-first AI apprenticeship platform where learners engage in spoken role-play scenarios with AI tutors, receive coaching debriefs, and progress via mastery gates — working on low-cost phones over constrained bandwidth.
|
||||
|
||||
## v0.2 Scope (Proxmox LXC Deployment)
|
||||
## v0.3 Scope (Mastery Scoring + Competency Rubrics — complete, retained for context)
|
||||
|
||||
v0.2 deploys praxis into a Proxmox LXC container, reusing and adapting the battle-tested deployment toolkit from `~/coreci/scripts/proxmox/`. The v0.1 voice loop becomes deployable infrastructure — a Docker image runs the Python/Pipecat server (serving the React client as static files) inside an LXC container on the operator's Proxmox cluster.
|
||||
v0.3 activated the mastery/assessment layer deferred from v0.1/v0.2 (per D-021, ROADMAP line 53). Learners progress via **mastery gates** — they move on only when they can do the thing across varied scenarios, scored against a competency rubric. v0.3 introduced a verifiable-credential issuer so mastery is portable. The operator tier (multi-tenant + auth + cohort dashboard) was deferred to v0.4 per GRILL-v0.3.md Axis 2.
|
||||
|
||||
**v0.3 in scope (activated REQ groups — post-grill):**
|
||||
- **Mastery core (REQ-MAST-01, REQ-MAST-02):** competency rubric per skill; Mastery Score updated after each session, requiring varied-scenario success before a mastery gate opens
|
||||
- **Verifiable credentials (REQ-MAST-03):** portable, tamper-evident credentials issued on week-final mastery gate (W3C VC Data Model 2.0, Ed25519, **formative-tier**, SQLite-backed issuer keys, public verification endpoint)
|
||||
- **Dynamic difficulty (REQ-SCEN-02):** scenario difficulty adjusts to learner performance (item-response-theory-informed)
|
||||
- **Scenario library (REQ-SCEN-03, REQ-SCEN-04):** library tagged by skill/difficulty/failure_mode; expert-authored format extended with rubric mappings + AI-generated variation hooks
|
||||
- **Path structure (REQ-PATH-02):** path-as-job 6-week structure (PRD §6.4) — the progression container mastery gates live in
|
||||
|
||||
**v0.3 out of scope (deferred to v0.4 per GRILL-v0.3.md Axis 2):**
|
||||
- **REQ-DASH-01 (cohort dashboard) + REQ-AUTH-01 (operator auth) + REQ-MT-01/02 (operator Postgres + aggregation) + 4 NFRs** — the operator tier was originally v0.8 on the ROADMAP; pulling it into v0.3 created a 2-milestone program. The grill's binding verdict splits it to v0.4. D-031 (override D-007) is deferred with the operator tier.
|
||||
- REQ-PATH-01 (full multi-path launch) — v0.3 ships the Customer Service path only

- Dynamic rubric weight re-weighting on branch outcome — static in v0.3 (grill Axis 9)
|

- Traefik proxy / public TLS — deferred from v0.2 (R-AUTH-01 deferred to v0.4 with the operator surface)
|
||||
|
||||
**Carries forward from v0.2 (already in production):**
|
||||
- Docker-in-LXC deployment (`lxc-deploy.sh`, `praxis.service`, `/health` :8789)
|
||||
- Voice loop (Deepgram Nova-3 + Cartesia + Pipecat + Ollama Cloud)
|
||||
- v0.1 scenario (`cs_refund_ca_v01.yaml`) + guardrails + debrief
|
||||
|
||||
## v0.4 Scope (Operator Tier — Cohort Dashboard + Auth + Postgres)
|
||||
|
||||
v0.4 activates the operator tier deferred from v0.3 per GRILL-v0.3.md Axis 2 (the operator tier was originally v0.8 on this ROADMAP; pulling it into v0.3 created a 2-milestone program disguised as one). The v0.3 mastery/VC/scenario work carries forward unchanged; v0.4 layers the operator surface on top of it.
|
||||
|
||||
**v0.4 in scope (activated REQ groups — 8 REQs total):**
|
||||
- **Operator-tier Postgres (REQ-MT-01):** second Docker service in the existing LXC CT (`docker-compose.yml` adds `postgres`), Postgres 16, persistent volume, internal Docker network only (D-040). Separate from learner-local SQLite (D-007 preserved for learner surface). Stores cohort aggregations, operator accounts, issued credentials, mastery-gate audit log.
|
||||
- **Cohort aggregation pipeline (REQ-MT-02):** on-session-end hook + nightly reconciliation job writes k-anonymized aggregates to Postgres from learner sessions (D-045). No raw learner PII in Postgres.
|
||||
- **Operator auth (REQ-AUTH-01):** session-cookie, argon2id passwords, single `operator` role, login rate-limited (5 attempts/min) (D-041). Cookie: httpOnly, secure, SameSite=Strict, 8h expiry. Protects cohort dashboard + credential issuance.
|
||||
- **Cohort dashboard (REQ-DASH-01):** anonymized cohort view (practice, mastery progression, failure patterns) for training operators — k-anonymity ≥ 10, 7-day aggregation window (D-034). React route under `/operator/*`, served by the same FastAPI server (new `/api/operator/*` prefix), reuses v0.2 StaticFiles (D-044). No separate SPA build — same `client/dist`.
|
||||
- **NFRs (4):** REQ-NFR-AUTH-01 (argon2id + httpOnly + secure + rate-limited), REQ-NFR-MT-01 (Postgres-in-LXC without destabilizing learner service), REQ-NFR-DASH-01 (k-anonymity ≥ 10 enforced — cells < 10 suppressed), REQ-NFR-DASH-02 (freshness ≤ 24h stale).
|
||||
|
||||
**v0.4 out of scope (still deferred):**
|
||||
- REQ-PATH-01 (full multi-path launch) — v0.3 ships Customer Service path only, multi-path later
|
||||
- REQ-DASH-02 (full operator-suite dashboard) — later milestone (v0.4 ships the foundational cohort view only)
|
||||
- REQ-ASSIST-01..03 (Live Assist) — later milestone
|
||||
- REQ-LOWBW-01..03 (WhatsApp/USSD/offline) — later milestone
|
||||
- REQ-VOICE-05/06 (multi-language, persona switching) — later milestone
|
||||
- Learner auth / multi-learner-per-device — operator auth is v0.4; learner auth later
|
||||
- RBAC (multiple operator roles) — single `operator` role in v0.4; RBAC deferred
|
||||
- Third-party credential issuers — v0.9 credentialing milestone
|
||||
- Differential privacy — k-anonymity ≥ 10 is sufficient for v0.4 scale (D-034)
|
||||
|
||||
**Carries forward from v0.3 (already in production):**
|
||||
- Mastery scoring + competency rubrics + IRT dynamic difficulty (v0.3)
|
||||
- Verifiable credential issuer (W3C VC 2.0, Ed25519, SQLite-backed) — v0.4 migrates the issuer key store to operator-tier Postgres + secrets (D-042)
|
||||
- Scenario library + Customer Service 6-week path (v0.3)
|
||||
- Docker-in-LXC deployment (v0.2)
|
||||
- Voice loop (Deepgram Nova-3 + Cartesia + Pipecat + Ollama Cloud) (v0.1)
|
||||
|

## v0.3 Scope (Mastery Scoring + Competency Rubrics — complete)
|
||||
|
||||
v0.3 activated the mastery/assessment layer deferred from v0.1/v0.2 (per D-021). Learners progressed via mastery gates — they moved on only when they could do the thing across varied scenarios, scored against a competency rubric. v0.3 shipped competency rubric engine + Mastery Score + scenario library (≥6 CS scenarios) + dynamic difficulty (IRT) + Customer Service 6-week path + verifiable-credential issuer (W3C VC 2.0, Ed25519, SQLite-backed, formative-tier, public verification). All learner-facing. Released as v0.1.5.

| D-044 | Cohort dashboard UI = **React route under `/operator/*`, served by the same FastAPI server (new prefix), reuses v0.2 StaticFiles** | REQ-DASH-01. Frontend-engineer reactivates (PERSONAS.md). Adds `/operator` React route + `/api/operator/*` FastAPI endpoints. Auth gate in React + server-side session check. No separate SPA build — same `client/dist`. | 0.75 | Separate operator SPA (extra build pipeline), server-rendered HTML (abandons React investment), no UI (operator reads JSON — not a product) |
|
||||
| D-045 | Cohort aggregation trigger = **on-session-end hook + nightly reconciliation job** | REQ-MT-02. Hook fires after `end_session()` → writes k-anonymized aggregate to Postgres (incremental). Nightly job (cron in the praxis service) reconciles + recomputes 7-day windows. Hybrid: low-latency updates + correctness guarantee. | 0.70 | Pure real-time (race-prone), pure nightly (stale, violates NFR-DASH-02 if job lags), CDC/streaming (over-engineered) |
|
||||
| D-046 | IRT θ persistence = **in learner-local SQLite** (`learner_ability` table: learner_id, path, theta, updated_at) | REQ-NFR-IRT-01. θ is per-learner-per-path, computed in-process on session end, no LLM call. Stays in SQLite with the rest of learner state (D-007 preserved). Cohort dashboard sees only k-anonymized aggregates of θ, never raw θ. | 0.80 | Postgres (couples learner state to operator tier — violates D-031 hybrid), in-memory (lost on restart), file-based JSON (no queryability) |
|
||||
| D-047 | Scenario library minimum for v0.3 = **≥6 expert-authored Customer Service scenarios** (one per path week) + **AI-generated variations gated by expert review** | REQ-SCEN-03/04. 6 scenarios give the mastery gate's N=3 varied-scenario condition room (D-032) without being so few that mastery is gameable. AI variations: LLM generates a variation from an expert scenario's schema with `generated_from` backref; expert reviews + approves before it enters the library. | 0.70 | 3 scenarios (mastery gate N=3 = exactly the minimum — no room for failure-retry variety), 12 scenarios (over-scoped for one milestone), no AI variations (loses REQ-SCEN-04) |
|
||||
| D-048 | Mastery gate open action = **advance learner to next path week + issue VC if week-final gate** | When D-032 condition met for a week's scenarios: learner `progress.current_week` advances. If the gate is the final week's gate, a VC is issued (REQ-MAST-03) asserting mastery of the path. Mid-path gates: no VC, just advancement. VCs are path-level, not week-level. | 0.75 | VC per week (credential spam — devalues the credential), no advancement (mastery gate is decorative), manual advancement (violates autonomy) |
|
||||
| D-049 | v0.3 activation of D-009 failure-injection = **NO** — failure-injection stays architecturally present but not provoked in v0.3 | D-009 hook stays in the schema. v0.3 mastery scoring scores *recovery* from naturally-occurring failure branches (the `escalate` branch in cs_refund_ca_v01), not AI-provoked failures. Active failure injection couples to a "failure-recovery coaching" feature that's a later milestone. v0.3 RESEARCH confirms this — no new failure-injection scenarios authored. | 0.80 | Activate failure injection in v0.3 (couples mastery scoring to a new feature — scope creep), remove the hook (breaks forward compat) |
|
||||
| D-050 | Postgres connection from praxis service = **asyncpg pool over Docker internal network, service DNS name `postgres`** | CLARIFY auto-decide (full autonomy). docker-compose defines a `postgres` service on an internal bridge network; the praxis service reaches it via `postgresql://praxis:${PRAXIS_PG_PASSWORD}@postgres:5432/praxis`. asyncpg is the async Pg driver (matches FastAPI async). No external port exposure. Single connection pool (min 1, max 10 — v0.4 scale). | 0.85 | psycopg2 sync (blocks event loop), external port + host access (security surface), pgbouncer (over-provisioned for v0.4 scale) |
|
||||
| D-051 | VC issuer key migration = **fresh keypair on first v0.4 boot; v0.3 SQLite-issued VCs remain verifiable via archived public key** | CLARIFY auto-decide. v0.3 stored the Ed25519 issuer key in SQLite (`issuer_keys` table). v0.4 generates a fresh keypair in Postgres `issuer_keys` (D-040), marks it `active`, and archives the v0.3 public key as `superseded` (not revoked — old VCs still verify against it). The verification endpoint tries the active key first, falls back to superseded keys for older credentials. No re-issuance of v0.3 VCs. | 0.80 | Re-issue all v0.3 VCs (unnecessary churn, learners hold old credentials), revoke v0.3 key (breaks old VCs), keep SQLite key store (defeats D-031 hybrid) |
|
||||
| D-052 | Operator account bootstrap = **first-run CLI script `scripts/create-operator.py` creates the initial operator from env-provided credentials** | CLARIFY auto-decide. No signup UI (operators are provisioned, not self-serve). Script reads `PRAXIS_BOOTSTRAP_OPERATOR_USER` + `PRAXIS_BOOTSTRAP_OPERATOR_PASS` from `.env.secrets`, hashes the password with argon2id, inserts into `operators` table. Idempotent (no-op if user exists). Subsequent operators added via the same script (run by the operator from the host). RBAC deferred (D-041 single role). | 0.80 | First-run web wizard (UI surface for a one-time action), hardcoded admin/admin (insecure), SQL insert (no password hashing) |
|
||||
| D-053 | Cohort dashboard v0.4 scope = **3 views: practice-volume, mastery-progression, failure-patterns — all k-anonymized ≥10, 7-day rolling windows** | CLARIFY auto-decide. REQ-DASH-01 names "practice, mastery progression, failure patterns" — v0.4 implements exactly those three views, no more. (1) Practice volume: sessions/day per path, anonymized. (2) Mastery progression: % learners at each week, gate-open rate. (3) Failure patterns: top failure modes by frequency, rubric criterion weak-spots. Each view = a `/api/operator/<view>` endpoint returning pre-aggregated rows from `cohort_aggregates`; React renders read-only tables + sparkline charts. No filters beyond path + window (no per-learner drill-down — k-anon). | 0.80 | Full BI dashboard (over-scoped for v0.4), single combined view (loses the three named aspects), per-learner drill-down (violates k-anon) |
|
||||
| D-054 | Aggregation trigger = **async fire-and-forget on session end (non-blocking); nightly reconciliation job at 03:00 CT** | CLARIFY auto-decide. D-045 named the trigger; this clarifies the semantics. On `end_session()`, the server enqueues an aggregation task to an in-process `asyncio.Task` (no Celery/Redis for v0.4 scale) — non-blocking, the session-end response returns immediately. Failures log + the nightly job reconciles (idempotent upsert by window). Nightly job: cron-style `asyncio.create_task` loop, recomputes all 7-day windows. If the service restarts, the in-flight task is lost but nightly reconciliation covers it. | 0.80 | Sync on session-end (adds latency to learner path — violates C-8), Celery+Redis (over-provisioned), CDC streaming (over-engineered) |
|
||||
| D-055 | Postgres backup = **nightly `pg_dump` to a named Docker volume, 7-day retention** | CLARIFY auto-decide. Postgres data lives on a named Docker volume (`pgdata`) inside the LXC CT. Nightly cron job runs `pg_dump praxis | gzip > /backups/praxis-$(date).sql.gz` to a second named volume (`pgbackups`). 7-day retention (rotates oldest). Operator can `pct pull` backups to the PVE host. No streaming replication (single CT, no replica target). This is pilot-tier backup; a later milestone adds off-CT replication. | 0.70 | No backups (data loss risk), WAL streaming to a replica (no replica in v0.4), S3 push (no S3 in LXC pilot) |
|
||||
| D-056 | Auth session store = **signed stateless cookies (HMAC-SHA256), no server-side session table** | CLARIFY auto-decide. D-041 said "session-cookie" — clarifying: the cookie is a self-contained signed token (user_id, issued_at, expiry, HMAC). No `sessions` table in Postgres. Verification = recompute HMAC + check expiry. Logout = client clears cookie (stateless — no server revocation list in v0.4). Rate limit is in-memory (single-instance). This minimizes DB load + simplifies the auth surface. A later milestone adds a revocation list if multi-instance or forced-logout is needed. | 0.75 | Postgres sessions table (DB load + cleanup job), Redis sessions (extra service), JWT with claims (same idea, more complex tooling) |
|
||||
| D-057 | Auth enforcement = **server-side on every `/api/operator/*` request + React route guard for UX, never trust the client** | CLARIFY auto-decide. FastAPI middleware checks the signed cookie on every `/api/operator/*` request; 401 if missing/invalid/expired. React `/operator/*` routes check a `/api/operator/me` call on mount and redirect to `/operator/login` if 401 — this is UX only, the server is the authority. The cohort dashboard reads only k-anonymized aggregates (D-034) so even an auth bypass leaks no PII (defense in depth). VC issuance endpoints (`/api/operator/credentials/*`) are also auth-gated. | 0.85 | Server-only (poor UX — no redirect), React-only (insecure — bypassable), no auth on issuance (credential forgery risk) |

|
||||
|
||||
## v0.4 Active Requirements
|
||||
|
||||
### Operator-Tier Postgres (v0.4 foundation)
|
||||
|
||||
| REQ-ID | Requirement | Priority | Phase | Status |
|
||||
|--------|-------------|----------|-------|--------|
|
||||
| REQ-MT-01 | Operator-tier Postgres store — cohort aggregations, operator accounts, issued credentials, mastery-gate audit log. Separate from learner-local SQLite (D-007 preserved for learner surface). Migration path: SQLite stays for learner; Postgres added for operator. Postgres 16, persistent volume, internal Docker network only (D-040). | must | P1 | active |
|
||||
| REQ-MT-02 | Cohort aggregation pipeline — on-session-end hook + nightly reconciliation job writes k-anonymized aggregates to Postgres from learner sessions (D-045). No raw learner PII in Postgres. | must | P1 | active |
|
||||
|
||||
### Operator Auth (v0.4)
|
||||
|
||||
| REQ-ID | Requirement | Priority | Phase | Status |
|
||||
|--------|-------------|----------|-------|--------|
|
||||
| REQ-AUTH-01 | Operator-tier auth — session-based, single `operator` role in v0.4. Operator accounts in Postgres. Login endpoint + session cookie. Protects cohort dashboard + credential issuance. argon2id passwords, httpOnly+secure cookie, SameSite=Strict, 8h expiry, login rate-limited 5/min (D-041). | must | P1 | active |
|
||||
|
||||
### Cohort Dashboard (v0.4)
|
||||
|
||||
| REQ-ID | Requirement | Priority | Phase | Status |
|
||||
|--------|-------------|----------|-------|--------|
|
||||
| REQ-DASH-01 | Anonymized cohort view (practice, mastery progression, failure patterns) for training operators — k-anonymity ≥ 10, 7-day aggregation window (D-034). Operator UI (React) under `/operator/*`, served by same FastAPI server (`/api/operator/*` prefix), reuses v0.2 StaticFiles (D-044). No separate SPA build — same `client/dist`. | must | P2 | active |
|
||||
|
||||
## v0.4 Non-Functional Requirements
|
||||
|
||||
| REQ-ID | Requirement | Target | Phase | Status |
|
||||
|--------|-------------|--------|-------|--------|
|
||||
| REQ-NFR-AUTH-01 | Operator auth — passwords hashed (argon2id), session cookie httpOnly + secure + SameSite=Strict, login rate-limited (5/min), 8h expiry | must | P1 | active |
|
||||
| REQ-NFR-MT-01 | Postgres-in-LXC — operator Postgres runs as a second Docker service in the existing LXC CT (D-040) without destabilizing the learner-facing praxis service. Internal Docker network only (not exposed to bridge). | must | P1 | active |
|
||||
| REQ-NFR-DASH-01 | Cohort dashboard k-anonymity ≥ 10 — any cohort view cell with < 10 learners is suppressed | must | P2 | active |
|
||||
| REQ-NFR-DASH-02 | Cohort dashboard freshness — aggregates ≤ 24h stale (nightly reconciliation + on-session-end hook per D-045) | must | P2 | active |
|
||||
|
||||
## v0.4 Out of Scope (still deferred)
|
||||
|
||||
- REQ-PATH-01 (full multi-path launch) — v0.3 ships Customer Service path only, multi-path later
|
||||
- REQ-DASH-02 (full operator-suite dashboard) — later milestone (v0.4 ships the foundational cohort view only)
|
||||
- REQ-ASSIST-01..03 (Live Assist) — later milestone
|
||||
- REQ-LOWBW-01..03 (WhatsApp/USSD/offline) — later milestone
|
||||
- REQ-VOICE-05/06 (multi-language, persona switching) — later milestone
|
||||
- Learner auth / multi-learner-per-device — operator auth is v0.4; learner auth later
|
||||
- RBAC (multiple operator roles) — single `operator` role in v0.4; RBAC deferred
|
||||
- Third-party credential issuers (university/agency) — v0.9 credentialing milestone
|
||||
- Differential privacy — k-anonymity ≥ 10 is sufficient for v0.4 scale (D-034)
|
||||
|
||||
## Constraints (binding — carry forward from v0.1/v0.2/v0.3)
|
||||
|
||||
- C-1 Voice is primary interface; text is fallback only
|
||||
- C-2 Must work on $100 Android phone over 2G/3G (relaxed for v0.1 Canada pilot)
|
||||
- C-3 Cost ≤ $3/active learner/month (relaxed for v0.1 pilot)
|
||||
- C-4 Audio-only in v1
|
||||
- C-5 Open-weights LLM via Ollama catalog — `gemma4:cloud` + `deepseek-v4-flash:cloud`
|
||||
- C-6 Domain safety guardrails + HITL + disclaimers for safety-sensitive domains
|
||||
- C-7 Scenarios authored by domain experts + learning designers; AI generates variations only
|
||||
- C-8 Latency budget < 600ms end-to-end (ASR → LLM → TTS) — mastery scoring + cohort aggregation must not be on the voice path

|
||||
| REQ-ID | Requirement | Priority | Phase | Status |
|
||||
|--------|-------------|----------|-------|--------|
|
||||
| REQ-MAST-01 | Competency rubric per skill — a typed rubric model (criteria, 5-level scale, per-skill weights) authored as YAML, mapped to scenarios (D-036). At least one rubric for the Customer Service path in v0.3. | must | P1 | complete |
|
||||
| REQ-MAST-02 | Mastery Score updated after each session — computed from rubric scores + varied-scenario-success gate (D-032: N=3 distinct scenarios, rubric mean ≥ 3.5/5.0). Score persisted per learner per path. Mastery gate opens when condition met. | must | P1 | complete |
|
||||
| REQ-MAST-03 | Portable verifiable credentials on mastery — W3C VC Data Model 2.0, platform-issued Ed25519 signatures, status-list revocation (D-033). Issued when a mastery gate opens. Verifiable by third parties via a public verification endpoint. | must | P1 | complete |
|
||||
| REQ-MAST-04 | No quizzes — assessment built into scenarios | principle | — | accepted |
|

### Scenario Engine (v0.3 extensions)

||||
|
||||
| REQ-ID | Requirement | Priority | Phase | Status |
|
||||
|--------|-------------|----------|-------|--------|
|
||||
| REQ-SCEN-02 | Dynamic difficulty adjustment based on learner performance — IRT 1PL/Rasch, Bayesian θ update per session (D-035). Difficulty selection picks next scenario targeting ~50% expected success for current θ. | must | P1 | complete |
|
||||
| REQ-SCEN-03 | Scenario library tagged by skill, difficulty, failure mode, rubric criteria — YAML directory + `scenarios/index.yaml` manifest (D-036). v0.3 ships ≥6 scenarios for the Customer Service path (one per week minimum). | must | P1 | complete |
|
||||
| REQ-SCEN-04 | Expert-authored scenario format with AI-generated variations — extends D-018 YAML DSL with rubric mapping + `generated_from` backref for AI variations. Expert-authored = canonical; AI variations = same schema, flagged, reviewable. | must | P1 | complete |
|
||||
|
||||
### Skill Paths (v0.3)
|
||||
|
||||
| REQ-ID | Requirement | Priority | Phase | Status |
|
||||
|--------|-------------|----------|-------|--------|
|
||||
| REQ-PATH-02 | Path structured as a job — 6-week structure per PRD §6.4, mastery-paced (D-037). Path = `paths/<slug>.yaml` defining weeks, each week = scenarios + a mastery gate. v0.3 ships the Customer Service path fully (6 weeks, ≥1 scenario/week). | must | P1 | complete |

# Praxis — v0.3 Research: Anonymization, IRT, Scenario Library
|
||||
|
||||
> **Milestone:** v0.3 (Mastery scoring + competency rubrics)
|
||||
> **Phase:** 0 (research — pre-execution)
|
||||
> **Branch:** phase/00-pre-execution
|
||||
> **Status:** research complete — pending orchestrator review
|
||||
> **Date:** 2026-08-03
|
||||
> **Method:** Domain-knowledge synthesis from the privacy-preserving analytics, psychometrics (IRT), and learning-content authoring literature. Where claims rest on a single source or empirical rule of thumb, the confidence score reflects that. Web-verification deferred — these are well-trodden fields with stable canonical references (Sweeney 2002; Machanavajjhala et al. 2007; Lord 1980; Rasch 1960; Wainer 2000; van der Linden 2010). No code is written here; this is decision input for the PLAN stage.
|
||||
> **Scope:** Three research question sets mapped to v0.3 decisions D-034 (cohort anonymization), D-035 (dynamic difficulty), D-036 (scenario library), D-047 (≥6 expert CS scenarios).
|
||||
|
||||
This document grounds three v0.3 subsystems — cohort anonymization, IRT-based dynamic difficulty, and the scenario library — in published evidence and gives concrete recommendations for the pilot scale (likely <100 learners in v0.3). Each subsection ends with a confidence score (0–1) and a recommendation keyed to the relevant D-ID.
|
||||

|
||||
|
||||
## Summary of Findings (Executive 1-Pager)
|
||||
|
||||
1. **k=10 + 7-day aggregation is the right floor for v0.3, and l-diversity is not yet warranted.** k-anonymity (Sweeney 2002) guarantees that any cohort view cell is indistinguishable across at least k learners. k=10 is the conventional minimum for anonymized analytics (HIPAA Safe Harbor uses k=5 for direct identifiers but k=10 is the common bar for aggregate cells). The known limits — homogeneity attacks (all k learners share the same sensitive value) and background-knowledge attacks — are real but require a sensitive-attribute dimension that v0.3's cohort view does not yet expose (the view shows practice volume, mastery progression, failure patterns — not diagnosis, income, or other high-stake attributes). **Recommendation:** ship k=10 + 7-day aggregation for v0.3; defer l-diversity/t-closeness to a later milestone if/when a sensitive attribute enters the cohort schema. (Confidence: 0.80)
|
||||
|
||||
2. **k-anonymity suppression is a SQL `HAVING COUNT(*) >= 10` pattern with a NULL/suppressed sentinel for small cells.** The robust pattern is a two-pass query: (a) compute the cell counts over the grouping dimensions, (b) suppress any cell with `< k` learners by replacing the measure with a sentinel (`NULL` or `'--'`) — never delete the row (deletion itself is a side channel). For multi-dimensional views (path × week × outcome), generalize (collapse) the sparsest dimension first rather than suppressing individual cells, so that suppression is monotone and doesn't create "negative space" that re-identifies. **Recommendation:** implement suppression in the aggregation pipeline (Postgres-side), not in the React client; expose a single `cell_suppressed` boolean column to the UI. (Confidence: 0.85)
|
||||
|
||||
3. **7-day aggregation is the standard privacy/analytics tradeoff and matches D-034.** Daily windows are re-identification-prone (a single learner practicing on a given day is often unique); monthly windows are too stale for an operator dashboard. 7 days is the conventional middle ground (matches HIPAA's "small cell" suppression granularity and common analytics practice). REQ-NFR-DASH-02 mandates ≤24h staleness for the *aggregate*, not the window — i.e., the 7-day window can roll daily with a ≤24h lag. **Recommendation:** roll the 7-day window daily (a trailing 7-day aggregate, recomputed nightly), keeping the window wide for k-anonymity and the freshness high for the operator. (Confidence: 0.80)
|
||||
|
||||
4. **Differential privacy is not worth adopting at v0.3 scale (<100 learners).** DP's noise scales as O(1/ε) independent of N, so at N<100 the noise needed for a meaningful ε swamps the signal in cohort cells. k-anonymity + aggregation is the right tool at pilot scale; DP becomes attractive at N>1000 where k-anonymity's suppression starts to delete too many cells. **Recommendation:** defer DP to a later milestone; document the migration path (k-anonymity → DP) in ARCHITECTURE.md. (Confidence: 0.75)
|
||||
|
||||
5. **1PL/Rasch is the correct IRT model for v0.3; θ is initialized to 0 (the population mean) and b is initialized by expert rating then refined by E-M / marginal MLE as data accrues.** P(success) = logistic(θ − b) = 1/(1+e^(b−θ)). The Bayesian update for θ after a session is a conjugate-style update on the posterior: posterior ∝ likelihood × prior, where the likelihood is Bernoulli with the observed session outcome (success/failure per the rubric gate) and the prior is N(θ₀, σ₀²). The closed-form Gaussian approximation (Bayesian update on the natural-parameter scale) is cheap (<1ms, satisfies REQ-NFR-IRT-01). **Recommendation:** initialize θ₀=0, σ₀²=1 (a weakly-informative prior that the learner is near the population mean); update θ and σ² after each session via the Gaussian-approximation update; persist both in the `learner_ability` SQLite table (D-046). (Confidence: 0.85)
|
||||
|
||||
6. **Target ~50% expected success for item selection — the "zone of proximal development" (60–70%) claim does not transfer cleanly from the classroom literature.** The classical CAT (Computerized Adaptive Testing) literature (Wainer 2000; van der Linden 2010) targets P=0.5 because that's where Fisher information for the 1PL is maximized (the test is most discriminating when the learner is right at the item's difficulty). The ZPD framing (Vygotsky; 60–70% success) is about *instructional* tasks, not *assessment* — and v0.3 scenarios are both. The compromise used in modern adaptive learning systems (e.g., Knewton, Duolingo's birdie model) is to target ~70% during practice and ~50% during assessment-only gates. **Recommendation:** target P=0.5 for mastery-gate scenarios (assessment role) and P≈0.7 for non-gate practice scenarios (learning role). Make the target a per-scenario field in the YAML so it's tunable without code changes. (Confidence: 0.75)
|
||||
|
||||
7. **θ is reasonably reliable after ~5–10 sessions; the cold-start prior (θ₀=0, σ₀²=1) carries the first 3–5 sessions.** The posterior variance σ² shrinks roughly as 1/n for 1PL Bayesian updates, so after 5 sessions σ² ≈ 0.2 (SD ≈ 0.45 logits, roughly half a rubric level), and after 10 sessions σ² ≈ 0.1 (SD ≈ 0.32 logits). v0.3's mastery gate requires N=3 *distinct* scenarios (D-032), so the gate itself provides a natural minimum of 3 data points before any gate decision — but θ should still be reported with its posterior SD until σ² < 0.2. **Recommendation:** report θ ± SD to the operator dashboard (k-anonymized); require σ² < 0.2 before θ drives item selection (fall back to expert-rated b otherwise). (Confidence: 0.80)
|
||||
|
||||
8. **1PL breaks down when scenario discrimination varies materially across scenarios — which v0.3's 6 expert scenarios will.** The 2PL model P=exp[a(θ−b)]/(1+exp[...]) adds a discrimination parameter `a` per item. The rule of thumb from the psychometric literature is that 2PL is justifiable at ~200–500 response records per item (Lord 1980; Embretson & Reise 2000), and 3PL (with a guessing parameter) needs ~1000+ per item. At v0.3's scale (<100 learners × ~6 scenarios = <600 records, ~100 per item), 1PL is the only defensible model; 2PL would be overfit. **Recommendation:** ship 1PL for v0.3; revisit 2PL only when per-scenario response counts exceed ~200 (likely post-pilot, v0.5+). (Confidence: 0.80)
|
||||
|
||||
9. **`scenarios/index.yaml` should be a manifest of metadata, not a duplicate of scenario content.** Each entry should carry: `id`, `path`, `difficulty` (the IRT `b` estimate, possibly expert-rated initially), `failure_mode`, `rubric_criteria` (list of rubric-criterion IDs exercised), `tags`, `version` (semver), `author` (expert name or `ai-variation`), `generated_from` (backref to parent scenario ID, absent for expert-authored), `irt_target_p` (the target success probability for selection, default 0.5 for gate scenarios). The index is the catalog the scenario selector reads; the per-scenario YAML files hold the full Pipecat-flows DSL. **Recommendation:** index.yaml = catalog (slim, fast to load); per-scenario YAML = full content (loaded on demand). Version with semver `MAJOR.MINOR.PATCH` — bump MAJOR on rubric-criteria or branch-structure changes (changes scoring compatibility), MINOR on content additions, PATCH on prompt tweaks. (Confidence: 0.85)
|
||||
|
||||
10. **AI-generated variations need a mandatory expert-review gate before entering the live library, a `generated_from` backref, and a frozen `intent_hash` to detect drift.** The review workflow: (a) LLM generates a variation from an expert scenario's schema with a `generated_from: <parent_id>` field, (b) the variation is written to a `scenarios/_pending/` directory and is *invisible* to the selector, (c) an expert reviews the YAML in a PR-style diff against the parent, (d) on approval the variation moves to `scenarios/<path>/` and is added to `index.yaml`. The drift-prevention mechanism: an `intent_hash` (SHA-256 of the parent scenario's `success_criteria` + `failure_mode` + `rubric_criteria` fields) is recorded on the variation at generation time; if the parent's intent changes (hash differs), the variation is flagged as stale and re-review is required. **Recommendation:** ship the pending-review directory + `generated_from` + `intent_hash` fields in v0.3; do NOT auto-promote AI variations without expert sign-off (C-7: scenarios authored by domain experts; AI generates variations only). (Confidence: 0.80)
|
||||
|
||||
11. **Rubric-to-scenario mapping is a list of rubric-criterion IDs on each scenario; coverage is checked by inverting the map at load time.** The YAML field is `rubric_criteria: [criterion_id, ...]` on each scenario (per D-036/D-039). To ensure every criterion in a path's rubric is exercised by ≥ N scenarios, load `rubrics/customer_service.yaml`, build the criterion-ID set, then walk `scenarios/index.yaml` and count scenarios per criterion; assert the minimum. **Recommendation:** add a `scripts/check-coverage.py` (or bats check) that fails the build if any rubric criterion for a path has < 2 covering scenarios (N=2 for v0.3 — gives one expert + one variation or two expert scenarios per criterion). Run it in CI and as a pre-merge gate. (Confidence: 0.85)

## 1. Anonymization (k-anonymity, D-034)
|
||||
|
||||
### Q1 — k-anonymity, k=10, and limits (homogeneity, background-knowledge; l-diversity/t-closeness for v0.3)
|
||||
|
||||
**What k-anonymity is.** k-anonymity (Sweeney, *International Journal of Uncertainty, Fuzziness and Knowledge-Based Systems* 2002) is a property of a released dataset (or aggregate view): for every combination of quasi-identifiers (the grouping dimensions — path, week, outcome, etc.), at least k records share that combination. Equivalently, no record is uniquely identifiable by the quasi-identifiers. The mechanism is generalization (collapsing values — e.g., age 23 → "20-30") and suppression (withholding cells with < k members).
|
||||
|
||||
**Why k=10 is the conventional minimum.** HIPAA Safe Harbor (45 CFR §164.514(b)) uses k=5 for *direct* identifiers in a released dataset (the 18-element rule). For *aggregate analytics cells* — which is what v0.3's cohort dashboard emits — the common bar in the privacy/analytics literature and in de-identification guidance (e.g., the CDC's re-identification risk guidance, the EU Pseudonymisation Best Practices) is k=10. The reasoning is that aggregate cells are subject to differencing attacks (subtracting two released aggregates to isolate a small subgroup), and a higher k than the direct-identifier minimum reduces the marginal risk. D-034's choice of k=10 is therefore the conventional, defensible floor.
|
||||
|
||||
**Limits of k-anonymity (the two classical attacks):**
|
||||
- **Homogeneity attack** (Machanavajjhala et al., *TODS* 2007, which introduced l-diversity): if all k learners in a cell share the same *sensitive* value, then knowing a target is in that cell reveals their sensitive value even though k-anonymity holds. Example: a cell of 10 learners who all failed the same week — knowing your competitor is in that cell tells you they failed.
|
||||
- **Background-knowledge attack**: an adversary with auxiliary information (e.g., "I know learner X practices on Tuesdays and is on week 3") can shrink the k-anonymity set to a smaller effective set and re-identify. k-anonymity is blind to this because it only counts released quasi-identifiers.
|
||||
|
||||
**l-diversity and t-closeness.** l-diversity (Machanavajjhala 2007) requires at least l *distinct* sensitive values per cell. t-closeness (Li, Li & Venkatasubramanian, *ICDE* 2007) requires the distribution of the sensitive attribute within a cell to be within t of the global distribution. Both address homogeneity; t-closeness additionally addresses skew attacks (where l-diversity is satisfied but the distribution is still skewed toward one value).
|
||||
|
||||
**Should v0.3 add l-diversity or t-closeness?** No — not for the pilot. The reason is structural: v0.3's cohort dashboard does not currently expose a *sensitive attribute* dimension in the sense the l-diversity/t-closeness literature assumes. The view dimensions are path/week/outcome/failure_pattern, and the measures are practice volume and mastery progression counts. None of these are sensitive in the way that diagnosis, income, or sexual orientation are. The homogeneity attack against "all 10 learners in this cell failed week 3" reveals a learning-struggle fact, which is lower-stakes than the medical/income facts these extensions were designed for. Adding l-diversity now would be engineering for a threat model the system doesn't yet have. The right trigger for revisiting l-diversity is *when a sensitive attribute enters the cohort schema* (e.g., if v0.4 adds demographic breakdowns). Document that trigger in ARCHITECTURE.md.
|
||||
|
||||
**Recommendation (D-034):** ship k=10 + 7-day aggregation for v0.3. Defer l-diversity/t-closeness with an explicit re-evaluation trigger: "revisit when any cohort-view dimension or measure becomes a sensitive attribute (demographic, socio-economic, health-related)." Keep the aggregation pipeline structured so adding l-diversity later is a localized change (one suppression predicate).
|
||||
|
||||
**Confidence: 0.80** — the k=10 convention is well-established; the l-diversity deferral is a threat-model judgment that depends on v0.3's exact cohort schema, which is not yet finalized. If the operator dashboard later adds a demographic filter, this deferral is wrong and l-diversity becomes required.
|
||||
|
||||
### Q2 — SQL suppression pattern; multi-dimensional views without re-identification
|
||||
|
||||
**Single-dimension suppression.** The canonical pattern for "any cohort view cell with < 10 learners is suppressed":
|
||||
|
||||
```sql
|
||||
SELECT
|
||||
path,
|
||||
week,
|
||||
outcome,
|
||||
CASE WHEN COUNT(DISTINCT learner_id) >= 10
|
||||
THEN COUNT(*)
|
||||
ELSE NULL
|
||||
END AS session_count,
|
||||
CASE WHEN COUNT(DISTINCT learner_id) >= 10
|
||||
THEN TRUE ELSE FALSE
|
||||
END AS cell_suppressed
|
||||
FROM session_aggregates
|
||||
WHERE window_start >= now() - interval '7 days'
|
||||
GROUP BY path, week, outcome;
|
||||
```
|
||||
|
||||
Two non-obvious but critical details:
|
||||
1. **Suppress the measure, not the row.** Deleting the row creates a "negative space" side channel: an adversary who knows the dimension space can enumerate all combinations and infer that a missing cell had < 10 learners — which, combined with background knowledge, can re-identify. Replacing the measure with `NULL` (or a `'--'` sentinel) and emitting the cell with `cell_suppressed = TRUE` preserves the dimension grid and only hides the count.
|
||||
2. **Use `COUNT(DISTINCT learner_id)`, not `COUNT(*)`.** A single learner can have many sessions in the window; `COUNT(*)` over-counts and produces false confidence that k=10 is met when only 3 learners are present. k-anonymity is about *people*, not *records*.
|
||||
|
||||
**Multi-dimensional views (path × week × outcome × failure_pattern).** The naive approach — suppress each cell independently — leaks via *differencing*: an adversary subtracts two released aggregates (e.g., "week 3 outcomes" minus "week 3 outcomes where failure_pattern = escalates_unresolved") to recover the suppressed subcell. The standard defenses are:
|
||||
- **Generalization (collapse the sparsest dimension first):** if path × week × outcome × failure_pattern has cells with < 10 learners, drop the sparsest dimension (usually failure_pattern) and re-emit at path × week × outcome. If still under k, drop outcome, etc. The release is a *lattice* of generalizations, not a flat table.
|
||||
- **Minimality / consistency constraints** (the approach from the k-anonymity generalization literature, e.g., LeFevre, DeWitt & Ramakrishnan, *SIGMOD* 2005): the released cells must be *minimal* — you can't suppress a cell when its parent generalization already satisfies k — and *consistent* — no two released cells overlap such that differencing recovers a suppressed cell.
|
||||
|
||||
For v0.3's pilot, the pragmatic approach is to (a) limit the cohort view to two dimensions at a time (e.g., path × week, OR path × outcome, but not path × week × outcome), which eliminates differencing across dimensions entirely; and (b) within each two-dimensional view, suppress cells with < 10 distinct learners using the pattern above. The operator UI presents a small fixed set of pre-defined 2-D views (no free-form cross-tabulation), which is sufficient for "practice volume, mastery progression, failure patterns" per REQ-DASH-01.
|
||||
|
||||
**Recommendation:** implement suppression Postgres-side in the aggregation pipeline (D-045's hook + nightly job); expose a fixed set of pre-defined 2-D cohort views; emit `cell_suppressed` boolean to the React client; render suppressed cells as `--` in the UI. Do NOT allow free-form cross-tabulation by the operator in v0.3.
|
||||
|
||||
**Confidence: 0.85** — the SQL pattern is canonical; the 2-D-view constraint is a pragmatic pilot choice that trades operator flexibility for re-identification safety. If operators need 3-D views, generalize (collapse) rather than allow free-form.
|
||||
|
||||
### Q3 — 7-day aggregation window: why 7 days, shorter-window risk, freshness tradeoff
|
||||
|
||||
**Why 7 days.** Three reasons, in descending order of weight:
|
||||
1. **Re-identification risk of shorter windows is high.** A daily window (or hourly) makes most cohort cells contain 1–3 learners (a single learner practicing on a given day is often unique in their path × week combination), so almost every cell would have to be suppressed, leaving the operator with a blank dashboard. Weekly windows aggregate enough practice that cells naturally exceed k=10 for active cohorts.
|
||||
2. **Practice periodicity is weekly.** Learners in a mastery-paced 6-week path (D-037) practice on the order of once a day to a few times a week; a 7-day window captures one full practice cycle and aligns with the path's week structure (the dashboard's "week" dimension matches the aggregation window, which is intuitive for operators).
|
||||
3. **Conventional granularity.** HIPAA Safe Harbor's "small cell" guidance, CDC re-identification guidance, and common analytics practice all treat 7-day (or coarser) aggregates as the privacy-friendly default for small populations.
|
||||
|
||||
**Re-identification risk of shorter windows.** A 1-day window: a cohort of 50 learners across 6 path-weeks gives ~8 learners per cell on average — already under k=10, so most cells suppressed. An adversary who knows "learner X practiced on Tuesday" can pin them to a specific daily cell; if that cell has 1–3 learners, re-identification is feasible. A 1-hour window is worse still. The risk scales inversely with window length for small populations.
|
||||
|
||||
**Freshness/staleness tradeoff.** The dashboard's freshness NFR (REQ-NFR-DASH-02: ≤ 24h staleness) is about *when the aggregate is computed*, not the window length. These are independent: a trailing 7-day window can be recomputed every hour (freshness 1h) or every day (freshness 24h). The window length is a *privacy* parameter; the recomputation cadence is a *freshness* parameter. The right design for v0.3 is a 7-day trailing window recomputed daily (or on each session-end per D-045's hook), giving 24h freshness on a 7-day-wide window. Shorter recomputation cadence (e.g., per-session) is fine — it doesn't change the window length.
|
||||
|
||||
**Recommendation (D-034):** 7-day trailing window, recomputed on session-end hook (low-latency incremental update) + nightly reconciliation job (correctness). Document explicitly that "7-day aggregation window" ≠ "7-day staleness" — the window is 7 days wide, the staleness is ≤24h per REQ-NFR-DASH-02.
|
||||
|
||||
**Confidence: 0.80** — the 7-day choice is conventional and well-justified for pilot scale; the freshness/window-length distinction is sometimes conflated in privacy guidance, which is why D-034's phrasing deserves the clarifying note above.
|
||||
|
||||
### Q4 — Differential privacy at v0.3 scale (<100 learners): adopt or defer?
|
||||
|
||||
**What differential privacy (DP) gives you that k-anonymity doesn't.** DP (Dwork, *ICALP* 2006) is a formal guarantee: the output distribution is nearly the same whether or not any individual's data is in the input. This protects against *all* auxiliary information (the background-knowledge attack that k-anonymity is blind to) and gives a quantifiable privacy budget (ε, δ). Mechanisms like the Laplace or Gaussian mechanism add noise calibrated to the query's sensitivity and the chosen ε.
|
||||
|
||||
**Why DP is the wrong tool at <100 learners.** The noise a DP mechanism adds is O(1/ε) *independent of N* — it does not shrink as the population grows. For a count query with sensitivity 1 and a privacy budget of ε=1 (a common, reasonably-private choice), the Laplace noise has scale 1 — meaning a true count of 8 might be released as 7, 8, 9, 10 with non-trivial probability. At N=50 learners in a cell, that's ±1–2 noise on a count of 50 — tolerable. At N=10 (the k-anonymity floor), ±1–2 noise on a count of 10 is ±10–20% relative error — the dashboard becomes meaningfully inaccurate. Worse, to maintain DP across many queries (the cohort dashboard emits many cells), the privacy budget must be *split* across them (composition), so each cell gets ε/M for M cells — and the noise scales as M/ε. A 6-path × 6-week × 4-outcome = 144-cell dashboard at total ε=1 gives ε_cell ≈ 0.007 — noise scale ~140, which makes the release pure noise.
|
||||
|
||||
k-anonymity, by contrast, has *no noise* — it either releases the exact count (when ≥ k) or suppresses (when < k). At small N, the suppression rate is the cost; at large N, suppression disappears and k-anonymity releases exact counts (which DP never does). The crossover where DP starts to outperform k-anonymity on the utility/privacy frontier is roughly N > 1000 for multi-cell dashboards (the exact threshold depends on the query workload and ε).
|
||||
|
||||
**Recommendation (D-034):** defer DP to a later milestone (target: when active learner count exceeds ~1000 or when a sensitive attribute enters the cohort schema, whichever comes first). Ship k-anonymity + aggregation for v0.3. Document the migration path in ARCHITECTURE.md: the aggregation pipeline's suppression step is a single function that can be swapped for a DP mechanism later — the rest of the pipeline (grouping, dimensions, UI rendering of `cell_suppressed`) is DP-agnostic.
|
||||
|
||||
**Confidence: 0.75** — the DP-at-small-N argument is well-grounded in the DP literature (Dwork & Roth 2014); the 1000-learner crossover is a rule-of-thumb, not a hard threshold, and depends on the exact query workload.

## 2. IRT (Item Response Theory, D-035)
|
||||
|
||||
### Q5 — 1PL/Rasch model: P(success)=logistic(θ−b), initialization, Bayesian θ update
|
||||
|
||||
**The model.** The 1PL (one-parameter logistic) / Rasch model gives the probability of success on scenario j by learner i as:
|
||||
|
||||
P(X_ij = 1 | θ_i, b_j) = 1 / (1 + exp(b_j − θ_i)) = logistic(θ_i − b_j)
|
||||
|
||||
where θ_i is learner i's ability (a scalar, in logits) and b_j is scenario j's difficulty (also in logits). The model is symmetric in θ and b: a learner of ability θ has P=0.5 on a scenario of difficulty b=θ; P>0.5 when θ>b; P<0.5 when θ<b.
|
||||
|
||||
**Initialization of θ (learner ability).** Three common choices:
|
||||
1. **Population mean (θ₀ = 0).** The conventional default. The logit scale is defined up to a translation, so fixing the population mean at 0 sets the scale. This is the right choice when there's no prior information about the learner.
|
||||
2. **Cold-start placement test.** Some CAT systems administer a short placement test to initialize θ. Praxis v0.3 has no quizzes (REQ-MAST-04: assessment is built into scenarios), so this is not available — the first scenario *is* the placement test.
|
||||
3. **Cohort-conditional prior.** If path-level performance data exists, initialize θ₀ to the mean θ of learners who have completed the path. Not available at v0.3 launch (no prior cohort).
|
||||
|
||||
**Recommendation:** θ₀ = 0 (population mean), prior variance σ₀² = 1 (weakly-informative — says "the learner is probably within ±2 logits of the population mean, which is ±2 rubric levels roughly"). This is the standard cold-start prior and is what py-irt, mirt (R), and pyjirt use by default.
|
||||
|
||||
**Initialization of b (scenario difficulty).** Three choices, in increasing data-intensity:
|
||||
1. **Expert rating (cold-start).** Have the scenario author rate the difficulty on the 1–5 rubric scale, then map to logits via b = (rating − 3) × c, where c is a scale factor (commonly c ≈ 1 logit per rubric level, calibratable). This is the only option at v0.3 launch — there is no response data yet.
|
||||
2. **E-M / marginal MLE from response data.** Once ~20+ response records exist for a scenario, estimate b via the Bock-Aitkin E-M algorithm (the standard IRT calibration method). This is offline, batch, and not in the voice path.
|
||||
3. **Joint MLE / hierarchical Bayes.** Estimates θ and b jointly; needs more data and is overkill for v0.3.
|
||||
|
||||
**Recommendation:** initialize b from expert rating at scenario authoring time (record `difficulty_expert: 1-5` in the YAML, derive `b_init`); recalibrate b offline (nightly job) via E-M once per-scenario response counts exceed ~20. Store both `b_init` and `b_calibrated` in `index.yaml`; the selector uses `b_calibrated` when available, else `b_init`.
|
||||
|
||||
**Bayesian update of θ after a session.** The session produces an outcome X ∈ {0, 1} (failure/success per the rubric gate — D-032). The posterior is:
|
||||
|
||||
p(θ | X) ∝ p(X | θ, b) × p(θ)
|
||||
= Bernoulli(X; logistic(θ − b)) × Normal(θ; θ_current, σ²_current)
|
||||
|
||||
This posterior is not Gaussian in closed form (the Bernoulli likelihood is logistic, not Gaussian). Two practical options:
|
||||
|
||||
**Option A — Gaussian approximation (Laplace / moment matching).** Approximate the posterior as Gaussian by matching the mode (MAP) and curvature. The update (one step of Newton's method on the log-posterior):
|
||||
|
||||
z = X − P_current # residual, P_current = logistic(θ_current − b)
|
||||
W = P_current × (1 − P_current) # variance of the Bernoulli
|
||||
θ_new = θ_current + (σ²_current × z) / (1 + W × σ²_current)
|
||||
σ²_new = σ²_current / (1 + W × σ²_current)
|
||||
|
||||
This is the standard "assumed density filtering" / "Bayesian logistic regression with a Gaussian prior" online update. It's O(1), well under 1ms (satisfies REQ-NFR-IRT-01's < 100ms), and is what most production adaptive learning systems use (Knewton's early models, Duolingo's half-life regression variant).
|
||||
|
||||
**Option B — Particle filter / grid approximation.** Maintain a discrete grid of θ values with weights; update weights by the Bernoulli likelihood. More accurate for the first few sessions when the Gaussian approximation is poor, but more code and slightly slower (still < 10ms for a 50-point grid). Overkill for v0.3.
|
||||
|
||||
**Recommendation (D-035):** Option A (Gaussian approximation). Initialize (θ=0, σ²=1). After each session-end, compute X from the rubric gate, look up b for the scenario, and apply the two-line update above. Persist (θ, σ², updated_at) in the `learner_ability` SQLite table per D-046. The update is in-process, no LLM call, < 1ms — comfortably within REQ-NFR-IRT-01.
|
||||
|
||||
**Confidence: 0.85** — the 1PL/Rasch model and the Gaussian-approximation Bayesian update are textbook psychometrics; the only judgment call is the prior variance (σ²=1), which is conventional but could be tuned once v0.3 produces real θ distributions.
|
||||
|
||||
### Q6 — Item selection: target P=0.5 or P=0.6–0.7 (ZPD)?
|
||||
|
||||
**The case for P=0.5 (max information).** In the 1PL model, the Fisher information about θ contained in a scenario of difficulty b is:
|
||||
|
||||
I(θ, b) = P(θ, b) × (1 − P(θ, b))
|
||||
|
||||
which is maximized at P=0.5 (i.e., b = θ). This is the theoretical basis for the classical CAT selection rule (Lord 1980, Wainer 2000, van der Linden 2010): pick the item that maximizes information about the learner's current θ, which is the item with b closest to θ. CAT systems used in high-stakes assessment (GRE, GMAT, ASVAB) target P=0.5 because their goal is to *estimate θ precisely in the fewest items* — efficiency.
|
||||
|
||||
**The case for P≈0.7 (zone of proximal development).** Vygotsky's ZPD framing — learners learn best on tasks slightly above their current independent level — has been interpreted in adaptive learning as targeting ~70–85% success (the learner succeeds most of the time but is stretched). Bjork's "desirable difficulties" framework argues for *some* failure to enhance long-term retention. The Knewton and Duolingo production systems target roughly 70–85% success during practice (Duolingo's "birdie" model targets ~80% recall).
|
||||
|
||||
**The conflict and the resolution.** The two targets answer different questions:
|
||||
- P=0.5 optimizes for *assessment precision* (estimating θ).
|
||||
- P=0.7 optimizes for *learning* (retention, engagement, low frustration).
|
||||
|
||||
Praxis v0.3 scenarios are *both* assessment and practice — they're scored against a rubric (assessment) and they're how the learner practices (learning). The split is:
|
||||
- **Mastery-gate scenarios** (the N=3 distinct scenarios that open a gate per D-032) are assessment: their purpose is to determine if the learner has mastered the week. Target P=0.5 (max information, hardest to game).
|
||||
- **Non-gate practice scenarios** are learning: their purpose is to develop the skill. Target P≈0.7 (ZPD, retention-friendly).
|
||||
|
||||
**Recommendation (D-035):** add a per-scenario `irt_target_p` field to the YAML (default 0.5 for gate scenarios, 0.7 for practice scenarios). The selector picks the unplayed scenario whose expected P = logistic(θ − b) is closest to the scenario's `irt_target_p`. This makes the target a content-authoring decision, not a code change, and lets learning designers tune per scenario. REQ-SCEN-02's "targeting ~50% expected success" is correct for the gate scenarios; the practice scenarios should deviate to 0.7.
|
||||
|
||||
**Confidence: 0.75** — the Fisher-information argument for P=0.5 is rigorous; the ZPD argument for P=0.7 is empirically supported in adaptive-learning production systems but less theoretically clean (Vygotsky's ZPD is a social-constructivist concept, and the "70%" mapping is a pragmatic interpretation, not a derived constant).
|
||||
|
||||
### Q7 — Cold-start: how many sessions until θ is reliable? What prior?
|
||||
|
||||
**How θ's posterior variance shrinks.** Under the Gaussian-approximation update in Q5, the posterior variance σ² shrinks by a factor (1 + W·σ²_current) per update, where W = P(1−P) ≤ 0.25. In the best case (P=0.5, W=0.25), each session halves σ² (when σ²=1: σ² → 1/(1+0.25) = 0.8 → 0.615 → 0.492 → ...). In the worst case (P near 0 or 1, W near 0), the session is uninformative and σ² barely shrinks. So the *number of sessions to reliability* depends on whether the scenarios are well-targeted (P near 0.5) or mis-targeted (P near 0 or 1).
|
||||
|
||||
Rough trajectory (assuming well-targeted scenarios, P≈0.5):
|
||||
- Start: σ² = 1.0 (SD = 1.0 logits, ±1 rubric level)
|
||||
- After 3 sessions: σ² ≈ 0.5 (SD = 0.7 logits, ±0.7 rubric level) — *this is when the mastery gate's N=3 distinct scenarios are first usable*
|
||||
- After 5 sessions: σ² ≈ 0.33 (SD = 0.57 logits)
|
||||
- After 10 sessions: σ² ≈ 0.18 (SD = 0.43 logits)
|
||||
- After 20 sessions: σ² ≈ 0.09 (SD = 0.30 logits)
|
||||
|
||||
**Rule of thumb:** θ is "reliable enough to drive item selection" at σ² < 0.2 (SD < ~0.45 logits, i.e., we know θ within half a rubric level), which takes ~5–10 well-targeted sessions. θ is "reliable enough to report on the cohort dashboard" at σ² < 0.1, which takes ~15–20 sessions.
|
||||
|
||||
**The cold-start prior.** The prior N(0, 1) says "the learner is probably within ±2 logits of the population mean," which is weakly informative. For v0.3 (no prior cohort data), this is the only defensible choice. Two alternatives, both deferred:
|
||||
- **Empirical Bayes prior:** once a cohort of learners has been through the path, set the prior mean/variance to the cohort's θ mean/variance. This shrinks the cold-start period for new learners.
|
||||
- **Path-conditional prior:** if different paths have different difficulty baselines, set the prior per path. Not needed in v0.3 (one path: Customer Service).
|
||||
|
||||
**The mastery-gate interaction.** D-032's mastery gate requires N=3 distinct-scenario successes with rubric mean ≥ 3.5/5.0. The gate is a *rule-based* condition independent of θ — the gate can open before θ is "reliable" by the σ² criterion. This is fine: the gate is the authoritative mastery signal; θ is for *item selection*, not for *mastery certification*. Don't conflate the two.
|
||||
|
||||
**Recommendation:**
|
||||
- Cold-start prior: N(0, 1) for θ at first session per path.
|
||||
- Item selection: use θ to select scenarios even from session 1 (with the broad prior, the selector will pick scenarios near b=0, which is correct — mid-difficulty).
|
||||
- Report θ to the operator dashboard only when σ² < 0.2 (else show "warming up — N sessions until reliable").
|
||||
- Mastery gate (D-032) is independent of θ's reliability — it's rule-based on rubric scores. Document this separation clearly.
|
||||
|
||||
**Confidence: 0.80** — the variance-shrinkage trajectory is derivable from the update equations; the σ² < 0.2 threshold for "reliable enough to report" is a judgment call (some systems use 0.1, some 0.25) but 0.2 is the common middle.
|
||||
|
||||
### Q8 — 1PL vs 2PL/3PL: when does 1PL break down? What data volume justifies 2PL?
|
||||
|
||||
**1PL (Rasch).** P = logistic(θ − b). One parameter per item (b). Assumes all items discriminate equally (the slope of the item characteristic curve is the same for every item). Strength: parsimonious, estimable from few responses per item (~20–50), θ is on an interval scale (specific objectivity — a defining Rasch property), and the model is robust to moderate violations of the equal-discrimination assumption.
|
||||
|
||||
**2PL.** P = logistic(a(θ − b)) where a is the item discrimination (slope). Two parameters per item. Allows items to differ in how sharply they distinguish learners above vs below the difficulty. A high-a item is very informative near b; a low-a item is weakly informative everywhere. Strength: better fit when discrimination genuinely varies. Weakness: needs more data to estimate `a` stably; θ loses specific objectivity (comparisons depend on the item set).
|
||||
|
||||
**3PL.** Adds a guessing parameter `c` (lower asymptote): P = c + (1−c)·logistic(a(θ−b)). Models the probability that a low-ability learner gets the item right by guessing. Useful for multiple-choice tests; **not applicable to Praxis** (scenarios are free-form voice role-plays, not multiple-choice — there is no "guessing" in the 3PL sense). 3PL needs ~1000+ responses per item to estimate `c` stably.
|
||||
|
||||
**When does 1PL break down?** 1PL is misspecified when the item discriminations vary substantially — i.e., when some scenarios are much better at distinguishing competent from incompetent learners than others. In Praxis terms, this would happen if (say) a "policy quote retrieval" scenario (high discrimination — only competent learners handle it) and a "smile and nod" scenario (low discrimination — everyone succeeds) are both in the library. The 1PL model would force both to have the same slope, distorting θ estimates. The empirical diagnostic is to fit 2PL, inspect the `a` estimates, and check if they cluster near a common value (1PL is fine) or spread widely (1PL is misspecified).
|
||||
|
||||
**Data volume thresholds (rule of thumb from the psychometric literature):**
|
||||
- 1PL: ~20–50 responses per item for stable b estimates.
|
||||
- 2PL: ~200–500 responses per item for stable `a` estimates (Lord 1980; Embretson & Reise 2000).
|
||||
- 3PL: ~1000+ responses per item.
|
||||
|
||||
**Praxis v0.3 numbers:** < 100 learners × 6 expert scenarios = < 600 total response records, ~100 per scenario (optimistically — not every learner plays every scenario). This is well above the 1PL threshold (~20–50) and well below the 2PL threshold (~200–500). 1PL is the only defensible model for v0.3; 2PL would be overfit and the `a` estimates would be noise.
|
||||
|
||||
**Recommendation (D-035):** ship 1PL for v0.3. Revisit 2PL when per-scenario response counts exceed ~200 (likely post-pilot, v0.5+). 3PL is permanently out of scope (no guessing in voice role-plays). When 2PL is adopted, fit it offline (E-M or MML); the online θ update generalizes naturally (the Gaussian-approximation update uses W = a²P(1−P) instead of P(1−P)).
|
||||
|
||||
**Confidence: 0.80** — the data-volume thresholds are well-established in the psychometric literature; the 1PL-for-v0.3 conclusion is robust to the exact learner count.

## 3. Scenario Library (D-036, D-047)
|
||||
|
||||
### Q9 — `scenarios/index.yaml` contents and scenario versioning
|
||||
|
||||
**Directory structure (per D-036):**
|
||||
|
||||
```
|
||||
scenarios/
|
||||
index.yaml # manifest / catalog
|
||||
customer_service/
|
||||
cs_refund_ca_v01.yaml # expert-authored
|
||||
cs_refund_exchange_v01.yaml # expert-authored
|
||||
cs_complaint_escalation_v01.yaml # expert-authored
|
||||
...
|
||||
_pending/ # AI variations awaiting review
|
||||
cs_refund_exchange_ai01.yaml
|
||||
cost_rates.yaml # existing v0.1 file
|
||||
rubric_criteria/ # optional: shared criterion defs
|
||||
empathy.yaml
|
||||
paths/
|
||||
customer_service.yaml # the 6-week path (D-037)
|
||||
rubrics/
|
||||
customer_service.yaml # the rubric (D-039)
|
||||
```
|
||||
|
||||
The existing `scenarios/customer_service_refund_ca_v01.yaml` is currently at the top level (flat); v0.3 nests it under `scenarios/customer_service/` to support the multi-path library. The flat layout worked for v0.1's single scenario; the nested layout is needed for v0.3's ≥6 scenarios across (initially) one path and (later) multiple paths.
|
||||
|
||||
**`index.yaml` contents (the manifest).** The index is a *catalog*, not a duplicate of scenario content. It carries the metadata the scenario selector and coverage checker need without loading every YAML file:
|
||||
|
||||
```yaml
|
||||
# scenarios/index.yaml — manifest, regenerated on library changes
|
||||
version: 1
|
||||
path_scenarios:
|
||||
customer_service:
|
||||
- id: cs_refund_ca_v01
|
||||

|
||||
difficulty_expert: 1 # 1-5 expert rating (cold-start b)
|
||||

|
||||

|
||||
author: expert_jane_doe
|
||||

|
||||

|
||||
status: live # live | pending | deprecated
|
||||
- id: cs_refund_exchange_ai01
|
||||
file: customer_service/cs_refund_exchange_ai01.yaml
|
||||
...
|
||||
generated_from: cs_refund_ca_v01
|
||||
status: pending # in _pending/, not selectable
|
||||
```
|
||||
|
||||
**Why index.yaml is separate from per-scenario YAMLs.** Loading 6+ full scenario YAMLs (each with multi-paragraph system prompts, branch definitions, rubric mappings) just to pick the next one is wasteful. The index is a slim catalog (~50 lines per scenario) loaded once at startup; the full scenario YAML is loaded on demand when selected. This also keeps the selector's logic testable without the LLM-prompt content.
|
||||
|
||||
**Versioning.** Use semver `MAJOR.MINOR.PATCH` per scenario, recorded in the scenario YAML and mirrored in `index.yaml`:
|
||||
- **MAJOR:** changes that break scoring compatibility — rubric_criteria added/removed, branch-structure changes, success_criteria semantics change. A MAJOR bump invalidates prior mastery-gate evidence (the learner's prior passes on the old version don't count toward the new version's gate).
|
||||
- **MINOR:** content additions — new common_mistakes, new branch (non-scoring), prompt enrichment. Backward-compatible with prior scoring.
|
||||
- **PATCH:** prompt tweaks, typo fixes, voice_id changes. No semantic change.
|
||||
|
||||
The `version` field on each scenario lets the mastery-gate audit log (REQ-NFR-MAST-02) record which scenario version a learner passed, so future re-authoring doesn't retroactively invalidate credentials.
|
||||
|
||||
**Recommendation (D-036):**
|
||||
- Nest scenarios under `scenarios/<path>/`.
|
||||
- `index.yaml` is a slim manifest (metadata only, ~50 lines/scenario).
|
||||
- Per-scenario YAML is the full Pipecat-flows DSL, loaded on demand.
|
||||
- Semver per scenario; MAJOR bumps invalidate prior gate evidence.
|
||||
- Add a `regenerate_index.py` (or bats check) that re-derives `index.yaml` from the scenario files and asserts they're in sync — prevents manual drift.
|
||||
|
||||
**Confidence: 0.85** — the index/manifest split is a standard content-management pattern; the semver scheme is conventional. The only judgment call is treating rubric_criteria changes as MAJOR (scoring-compatibility-breaking), which is the conservative choice.
|
||||
|
||||
### Q10 — AI-generated variations: review workflow, generated_from backref, drift prevention
|
||||
|
||||
**The workflow (per D-047, C-7).** C-7 (binding constraint) states "Scenarios authored by domain experts + learning designers; AI generates variations only." D-047 specifies "AI-generated variations gated by expert review." The concrete workflow:
|
||||
|
||||
```
|
||||
1. GENERATE
|
||||
- Input: an expert scenario YAML (e.g., cs_refund_ca_v01.yaml)
|
||||
- LLM (deepseek-v4-flash:cloud with think mode — offline, not latency-bound)
|
||||
generates a variation by perturbing the scenario while preserving
|
||||
success_criteria + failure_mode + rubric_criteria.
|
||||
- Output: a new YAML in scenarios/<path>/_pending/<id>.yaml with:
|
||||
generated_from: cs_refund_ca_v01
|
||||
intent_hash: <sha256 of parent's success_criteria+failure_mode+rubric_criteria>
|
||||
status: pending
|
||||
author: ai_variation_<model_version>
|
||||
|
||||
2. REVIEW (expert, human-in-the-loop)
|
||||
- Expert opens a PR-style diff: pending YAML vs parent YAML.
|
||||
- Expert checks: does the variation still exercise the same rubric_criteria?
|
||||
Is the failure_mode still reachable? Is the system_prompt safe + in-character?
|
||||
- Expert may edit the variation (the LLM output is a draft, not final).
|
||||
- On approval: expert moves the file from _pending/ to scenarios/<path>/
|
||||
and adds it to index.yaml with status: live.
|
||||
|
||||
3. PUBLISH
|
||||
- The variation is now selectable by the IRT scenario selector.
|
||||
- It carries generated_from permanently (for provenance/audit).
|
||||
- Its intent_hash is frozen at generation time.
|
||||
|
||||
4. DRIFT DETECTION (ongoing)
|
||||
- If the parent scenario is re-authored (MAJOR version bump) and its
|
||||
success_criteria/failure_mode/rubric_criteria change, the parent's
|
||||
intent_hash changes. All variations generated_from that parent are
|
||||
flagged as stale (their intent_hash no longer matches the parent).
|
||||
- Stale variations are moved back to _pending/ and require re-review
|
||||
before they're selectable again.
|
||||
```
|
||||
|
||||
**The `generated_from` backref.** A single field on the variation YAML pointing to the parent scenario ID. Absent (or null) on expert-authored scenarios. This is the provenance chain — it lets the audit log answer "was this mastery-gate evidence collected on an expert scenario or an AI variation, and if the latter, from which expert scenario was it derived?" The chain is one level deep (an AI variation is generated from an expert scenario, not from another AI variation) — this is a deliberate constraint to prevent variation-of-variation drift. Enforce it at generation time.
|
||||
|
||||
**Drift prevention via `intent_hash`.** The intent of a scenario is defined as the tuple (success_criteria, failure_mode, rubric_criteria) — the parts that determine what the scenario *assesses*. The `intent_hash` is SHA-256 of the canonical JSON encoding of that tuple. At generation time, the variation records the parent's intent_hash. If the parent's intent later changes (re-authoring changes the rubric_criteria, say), the parent's hash changes and the variation is flagged stale. This catches the case where an expert reauthors the parent in a way that the variation no longer faithfully represents — without requiring the expert to manually track all variations.
|
||||
|
||||
**Preventing drift from the expert's intent (the deeper question).** The intent_hash catches *parent-side* drift. *Variation-side* drift — the LLM produces a variation that superficially matches the schema but subtly changes the assessed skill (e.g., makes the customer less angry, turning an empathy test into a transaction test) — is caught only by expert review. The intent_hash does NOT verify semantic fidelity. Two mitigations:
|
||||
1. **The rubric-to-scenario mapping is part of the intent tuple.** If the LLM drops a rubric criterion, the variation's intent_hash differs from the parent's, and the variation is auto-flagged stale (without needing expert review). This catches structural drift.
|
||||
2. **Expert review is the only defense against semantic drift within the same rubric_criteria.** No automated check can verify "is this customer still angry enough to test empathy." This is why C-7 makes expert review mandatory, not optional.
|
||||
|
||||
**Recommendation (D-047, REQ-SCEN-04):**
|
||||
- Ship the `_pending/` directory + `generated_from` backref + `intent_hash` fields in v0.3.
|
||||
- AI variations are generated offline by `scripts/generate_variation.py` (a CLI tool, not in the voice path); output goes to `_pending/`.
|
||||
- Expert review is mandatory; no auto-promotion. The review is a git PR against the `scenarios/` directory — the expert reviews the YAML diff.
|
||||
- One-level variation chain only (no variations of variations).
|
||||
- `intent_hash` catches structural drift (rubric_criteria change); expert review catches semantic drift.
|
||||
- The ≥6 expert scenarios in D-047 are the floor; AI variations are supplemental and cannot substitute for the expert floor.
|
||||
|
||||
**Confidence: 0.80** — the workflow is sound and matches industry practice for AI-assisted content authoring (e.g., how Khanmigo, Duolingo's GPT-4 content pipeline handle AI-generated exercises). The `intent_hash` mechanism is a Praxis-specific design; it's a reasonable heuristic for structural drift but is not a published technique, hence the 0.80 not 0.95.
|
||||
|
||||
### Q11 — Rubric-to-scenario mapping: YAML field shape, coverage across a path
|
||||
|
||||
**The YAML field shape.** Each scenario declares which rubric criteria it exercises via a `rubric_criteria` field — a list of criterion IDs that reference the rubric file (`rubrics/customer_service.yaml` per D-039):
|
||||
|
||||
```yaml
|
||||
# scenarios/customer_service/cs_refund_ca_v01.yaml
|
||||
id: cs_refund_ca_v01
|
||||
path: customer_service
|
||||
# ... existing v0.1 fields ...
|
||||
rubric_criteria:
|
||||
- criterion_id: empathy
|
||||
weight: 1.0 # relative weight within this scenario (default 1.0)
|
||||
evidence_required: true # must be observed to count toward mastery
|
||||
- criterion_id: concrete_resolution
|
||||
weight: 1.0
|
||||
evidence_required: true
|
||||
- criterion_id: next_steps
|
||||
weight: 0.5
|
||||
evidence_required: false
|
||||
```
|
||||
|
||||
Two design choices in this shape:
|
||||
1. **List of objects, not a list of strings.** Each entry carries a `criterion_id` (referencing the rubric) plus per-scenario metadata about that criterion (weight within this scenario, whether evidence is required). A bare list of strings (`rubric_criteria: [empathy, concrete_resolution, next_steps]`) is simpler but loses the per-scenario weighting — and weighting matters because a scenario may exercise one criterion as the primary skill and another as secondary.
|
||||
2. **Reference by ID, not inline.** The criterion's full definition (5-level anchors, weight-within-skill) lives in `rubrics/customer_service.yaml` (per D-039). The scenario references it by ID. This keeps the rubric single-source (a criterion's anchors are defined once) and lets the coverage checker work on IDs without parsing every scenario's full content.
|
||||
|
||||
**Coverage across a path.** D-032's mastery gate requires N=3 distinct-scenario successes. For the gate to be meaningful, the N scenarios must collectively exercise *all* the rubric's criteria — otherwise a learner could pass the gate by succeeding on scenarios that only test a subset of the skill. The coverage requirement is: *every rubric criterion for the path is exercised by ≥ M scenarios, where M ≥ 2* (so there's at least one expert scenario and one alternative — an AI variation or a second expert scenario — to prevent single-scenario gaming).
|
||||
|
||||
**Coverage check (load-time).** Build the rubric-criterion-ID set from `rubrics/customer_service.yaml`, walk `scenarios/index.yaml`, and count scenarios per criterion (only `status: live` scenarios count):
|
||||
|
||||
```python
|
||||
# pseudocode for scripts/check_coverage.py
|
||||
rubric = yaml.safe_load(open("rubrics/customer_service.yaml"))
|
||||
required_criteria = {c["id"] for c in rubric["criteria"]}
|
||||
index = yaml.safe_load(open("scenarios/index.yaml"))
|
||||
scenarios = [s for s in index["path_scenarios"]["customer_service"]
|
||||
if s["status"] == "live"]
|
||||
coverage = {cid: sum(1 for s in scenarios if cid in s["rubric_criteria"])
|
||||
for cid in required_criteria}
|
||||
under_covered = {cid: n for cid, n in coverage.items() if n < MIN_COVERAGE}
|
||||
if under_covered:
|
||||
fail(f"Coverage gap: {under_covered} — each criterion needs ≥ {MIN_COVERAGE} scenarios")
|
||||
```
|
||||
|
||||
With `MIN_COVERAGE = 2` for v0.3. This runs at CI time and as a pre-merge gate on `scenarios/` changes.
|
||||
|
||||
**Interaction with D-047's ≥6 scenarios.** Six expert scenarios × 3 rubric criteria per scenario = 18 criterion-exercise slots. If the rubric has 5 criteria, each needs ≥ 2 scenarios = 10 slots minimum — well within the 18 available, so 6 scenarios is comfortably enough for coverage *if* the scenarios are authored to distribute across criteria (not all 6 testing only empathy + concrete_resolution). The coverage check catches the case where authoring concentrates on a subset of criteria.
|
||||
|
||||
**Recommendation (D-036, D-039, D-047):**
|
||||
- `rubric_criteria` on each scenario is a list of objects: `{criterion_id, weight, evidence_required}`.
|
||||
- Criterion definitions live in `rubrics/<skill>.yaml` (per D-039); scenarios reference by ID.
|
||||
- Coverage check: every criterion in the path's rubric is exercised by ≥ 2 live scenarios (`MIN_COVERAGE = 2` for v0.3).
|
||||
- `scripts/check_coverage.py` runs in CI; fails the build on coverage gaps.
|
||||
- Authoring guidance for the ≥6 expert scenarios: distribute across criteria so no criterion is exercised by only one scenario.
|
||||
|
||||
**Confidence: 0.85** — the ID-reference pattern is standard content-relationship modeling; the coverage check is a straightforward graph invariant. The `MIN_COVERAGE = 2` choice is a v0.3 pragmatic floor (it could be raised to 3 in later milestones for more robust anti-gaming, at the cost of more authoring).
|
||||
|

|
||||
|
||||
## Cross-Cutting Recommendations for the PLAN Stage
|
||||
|
||||
1. **Anonymization pipeline is a single suppression function, swappable for DP later.** Design `aggregate_cohort(dimensions, window)` to return rows with a `cell_suppressed` column. The k-anonymity suppression is one predicate (`COUNT(DISTINCT learner_id) >= 10`); a future DP mechanism replaces the predicate with a noise-addition step. The UI and the rest of the pipeline are unchanged.
|
||||
|
||||
2. **IRT θ update and mastery gate are independent.** Don't couple them. The mastery gate (D-032) is rule-based on rubric scores + N=3 distinct scenarios. θ (D-035) is for *scenario selection*, not for *mastery certification*. A learner can open a mastery gate before θ is "reliable" by the σ² criterion, and that's correct — the gate is the authoritative mastery signal.
|
||||
|
||||
3. **Scenario library is the linchpin.** Three v0.3 subsystems read from it: the IRT selector (reads `difficulty`, `irt_target_p`), the coverage checker (reads `rubric_criteria`), and the mastery gate (reads `status`, `version`, `generated_from`). Design `index.yaml` first; the rest follows.
|
||||
|
||||
4. **Expert authoring is the bottleneck.** D-047's ≥6 expert CS scenarios is a content-authoring task, not an engineering task. The PLAN stage should identify the persona (learning designer + domain expert) and the schedule for authoring the 6 scenarios, and treat it as a critical-path dependency for the IRT and mastery-gate slices.
|
||||
|
||||
5. **Three CI gates for the scenario library:**
|
||||
- `scripts/check_coverage.py` — every rubric criterion exercised by ≥ 2 live scenarios.
|
||||
- `scripts/check_index_sync.py` — `index.yaml` is in sync with the per-scenario YAMLs (no missing entries, no stale entries).
|
||||
- `scripts/check_intent_hash.py` — no live scenario has a stale `intent_hash` (catches parent-reauthoring drift).
|
||||

## Open Questions for the PLAN Stage
|
||||
|
||||
1. **Cohort view dimensions — exact set.** Q2 recommends 2-D views only. Which 2-D views does the operator dashboard expose? Candidate set: path × week (progression), path × outcome (mastery), path × failure_pattern (diagnostics). Confirm with the operator persona (training manager) before PLAN.
|
||||
|
||||
2. **IRT `b` recalibration cadence.** Q5 recommends nightly E-M recalibration of `b` once per-scenario response counts exceed ~20. At v0.3's scale (~100 responses per scenario), nightly is overkill — weekly is fine. But the trigger ("recalibrate when count > 20") needs to be in the nightly job, not hardcoded.
|
||||
|
||||
3. **AI variation generation tooling.** Q10 specifies `scripts/generate_variation.py` as an offline CLI. Does it run locally (expert's laptop) or in the praxis container? Locally is simpler (no LLM-in-production-container concern); the output is a YAML file checked into git. Recommend local.
|
||||
|
||||
4. **Mastery-gate evidence and scenario versioning.** Q9 specifies MAJOR bumps invalidate prior gate evidence. Concretely: if `cs_refund_ca_v01` is bumped to `cs_refund_ca_v02` with a rubric_criteria change, do learners who passed v01 need to re-pass v02? The conservative answer is yes (re-pass required), but this is a UX/policy decision that the PLAN stage should surface to the product owner.
|
||||
|
||||
5. **Operator dashboard: θ reporting threshold.** Q7 recommends reporting θ only when σ² < 0.2. Should the dashboard show "warming up — N sessions until reliable" for learners below the threshold, or suppress entirely? Showing a count is more useful but leaks information about how few sessions the learner has (a re-identification vector if combined with other cells). Recommend: aggregate the "warming up" count across the cohort (k-anonymized), don't show per-learner.

# Praxis — Research Findings (v0.4 Operator Tier — Cohort Dashboard + Auth + Postgres)
|
||||
|
||||
> **Phase:** v0.4 research (operator tier)
|
||||
> **Branch:** `phase/00-pre-execution`
|
||||
> **Status:** research complete — pending orchestrator review
|
||||
> **Date:** 2026-08-04
|
||||
> **Method:** Codebase inspection (`server/`, `db/`, `docker-compose.yml`, `client/`, `pyproject.toml`, `client/package.json`), v0.3 research appendices (`.ciagent/RESEARCH.md`, `docs/RESEARCH-operator-postgres-auth.md`, `.ciagent/RESEARCH-vc.md`, `.ciagent/RESEARCH-v0.3-anonymization-irt-scenarios.md`), D-050..D-057 decision text, OWASP Password Storage Cheat Sheet (fetched 2026-08-04), Postgres 16 documentation, asyncpg/Starlette/argon2-cffi ecosystem knowledge. Web-verified where possible; domain-knowledge claims carry explicit confidence scores.
|
||||
|
||||
This document grounds the v0.4 operator-tier architecture in ecosystem evidence. It covers all 7 research domains and concludes with a consolidated risks table and a v0.3-assumption audit (which anticipatory assumptions were confirmed, which were overturned by D-050..D-057).

||||

|
||||
|
||||
## Summary of Findings (Executive 1-Pager)
|
||||
|
||||
1. **Postgres 16-slim is the correct second service.** (0.90) `postgres:16-slim` (Debian-slim, glibc) matches the existing praxis Dockerfile rationale. Named volume `pgdata`, explicit `praxis-net` bridge network (no published port), `pg_isready` healthcheck, `depends_on: service_healthy`. PG16 ships `gen_random_uuid()` in core (no extension). asyncpg `create_pool(min_size=1, max_size=10)` on `app.state.pg_pool` via lifespan, `command_timeout=10`. CT memory bump 4GB→6GB (confirmed by v0.3 anticipatory section; D-050 fixes pool min at 1, not 2 — lower idle cost). Nightly `pg_dump -Fc` to `pgbackups` volume, `%u` 7-file rolling retention (D-055).
|
||||
|
||||
2. **Operator auth = signed stateless cookies (HMAC-SHA256 via Starlette SessionMiddleware) + argon2id + in-memory rate limit.** (0.88) D-056 overrides the v0.3 anticipatory "SessionMiddleware (itsdangerous-signed)" framing slightly — the architecture uses Starlette's SessionMiddleware which *is* itsdangerous-signed under the hood, so the v0.3 description holds. argon2-cffi `PasswordHasher` defaults (time_cost=3, memory_cost=64MiB, parallelism=4) **exceed** OWASP minimums (19MiB/t=2/p=1). `check_needs_rehash` for param upgrades. Login rate limit = in-memory `dict[ip, (count, window_start)]` dependency (D-057 + D-041); slowapi is the idiomatic FastAPI choice but a hand-rolled counter is simpler for single-instance and avoids a dep — **recommend slowapi for idiomaticity** (0.70) with the hand-rolled counter as the documented fallback.
|
||||
|
||||
3. **Secure cookie + no-TLS pilot tension → config-driven `Secure` flag, document the pilot risk.** (0.75) D-030 (no Traefik/TLS for pilot) conflicts with the `Secure` cookie attribute (requires HTTPS). Resolution: **(a) config-driven** — `PRAXIS_COOKIE_SECURE` env var (default `true`); set `false` only for the HTTP pilot, with a logged WARNING + a grill-tracked R-AUTH-01 mitigation. This is the safest minimal path: no new infra (Caddy/nginx would be a 3rd service), the flag flips automatically when TLS is added later. Reject option (c) minimal TLS via Caddy — adds a 3rd Docker service, breaks D-030's "direct bridge IP access" pilot stance, and TLS certs need a CA (self-signed → browser warnings worse than HTTP for a pilot). **The cohort dashboard reads only k-anonymized aggregates (D-034), so even a cookie sniffed over HTTP leaks no PII — defense in depth.**
|
||||
|
||||
4. **k-anonymity ≥ 10 enforced at write time via cell suppression in the aggregation SQL.** (0.85) `COUNT(DISTINCT learner_ref) >= 10` guard; cells below threshold are written with `cell_suppressed = TRUE` and `value = NULL`. 7-day rolling window computed on read via window functions over `cohort_aggregates` rows (incremental upsert by `(path, metric, window_start)`). No materialized view needed at v0.4 scale (<100 learners) — the nightly job recomputes all 7-day windows. Differencing attacks blocked by limiting to pre-defined 2-D views (path × week, path × outcome) per the v0.3 anonymization research.
|
||||
|
||||
5. **Aggregation trigger = async fire-and-forget `asyncio.Task` on session end + nightly reconciliation at 03:00 CT.** (0.82) D-054 confirms. The existing `SessionRecorder.end()` already schedules mastery flow via `asyncio.create_task` (line 143 of `session_recorder.py`) — the v0.4 aggregation hook follows the same pattern, chained after the mastery flow. Failures log + nightly job reconciles (idempotent upsert by window). Nightly job = in-process `asyncio.create_task` loop with `asyncio.sleep` until 03:00; no APScheduler (over-engineered for one cron job). If the service restarts, the in-flight task is lost but nightly reconciliation covers it.
|
||||
|
||||
6. **3 dashboard views = practice-volume, mastery-progression, failure-patterns — all k-anonymized, 7-day windows.** (0.82) D-053. Practice volume: sessions/day per path. Mastery progression: % learners at each week, gate-open rate. Failure patterns: top failure modes by frequency + rubric criterion weak-spots. Each view = a `/api/operator/<view>` endpoint returning pre-aggregated rows from `cohort_aggregates`; React renders read-only tables + sparkline charts. **No chart library is in `client/package.json`** — only react, react-dom, pipecat client SDK. Recommend **uPlot** (~40KB, sparkline-native, no React dependency) or inline SVG sparklines (~50 LOC, zero deps). Inline SVG is the v0.4 recommendation (zero deps, k-anon tables are small).
|
||||
|
||||
7. **VC issuer key migration = fresh keypair in Postgres `issuer_keys`; v0.3 SQLite public key archived as `superseded`.** (0.85) D-051. The existing `server/vc/issuer_keys.py` already implements the `active`/`superseded` lifecycle + `get_public_key_for_verification(key_id)`. v0.4 splits the issuer key store: Postgres `issuer_keys` (new active key) + archived v0.3 public key (status `superseded`). The verification endpoint (`server/vc/verification.py:verify_credential`) extracts `key_id` from the proof's `verificationMethod` and looks up the public key — the fallback to superseded keys is already implicit in `get_public_key_row(key_id)` (it queries by id, not by status). **No re-issuance of v0.3 VCs.** Private key encrypted at rest via `nacl.SecretBox` with `PRAXIS_VC_ISSUER_KEY` root key (existing pattern in `issuer_keys.py`).
|
||||
|
||||
8. **Operator account bootstrap = `scripts/create-operator.py` CLI, argon2id hash, idempotent insert.** (0.85) D-052. Reads `PRAXIS_BOOTSTRAP_OPERATOR_USER` + `PRAXIS_BOOTSTRAP_OPERATOR_PASS` from env, hashes with argon2-cffi, inserts into Postgres `operators` table with `ON CONFLICT (username) DO NOTHING`. Run from the host via `docker compose exec praxis python scripts/create-operator.py` or directly in the CT. No signup UI.
|
||||
|
||||
9. **Persona roster for v0.4: 6 active (lead-developer, backend-engineer, frontend-engineer REACTIVATED, data-engineer REACTIVATED/EXPANDED, security-engineer RETAINED, devops-engineer REACTIVATED for Postgres-in-LXC).** (0.90) v0.3 deactivated frontend-engineer + devops; v0.4 reactivates both. security-engineer retained (auth + crypto migration). data-engineer expands to Postgres schema + aggregation SQL. devops-engineer owns the docker-compose Postgres service + CT memory bump + backup cron + `create-operator.py` bootstrap script.

## Domain 1: Postgres 16 in Docker-in-LXC (D-040, D-050, D-055, REQ-NFR-MT-01)
|
||||
|
||||
### 1.1 Postgres 16-slim resource footprint inside an LXC CT
|
||||
|
||||
**Finding (0.88):** `postgres:16-slim` is Debian-slim-based (glibc), matching the praxis Dockerfile's rationale (avoiding Alpine musl locale issues with `pg_*` clients). The slim image is ~80MB compressed / ~200MB unpacked. Postgres 16 idle memory footprint with default `shared_buffers=128MB` is ~150-250MB RSS. With a small pilot workload (<100 learners, low-frequency operator queries), total Postgres RSS stays under ~400MB.
|
||||
|
||||
**Resource contention with the learner-facing praxis service:** The praxis container (uvicorn + Pipecat + voice loop) uses ~500MB at runtime (per v0.2 RESEARCH.md Q9). Postgres adds ~400MB. Docker daemon ~200MB. CT base ~200MB. Total ~1.3GB runtime, leaving ~4.7GB headroom on a 6GB CT. **The voice loop is latency-sensitive (C-8: <600ms); Postgres queries are off the voice path** (operator endpoints + nightly aggregation only). The risk is disk I/O contention during the nightly `pg_dump` + aggregation job — mitigated by scheduling at 03:00 CT (low learner activity) and the aggregation job being incremental upserts (not a full table scan).
|
||||
|
||||
**CT memory bump:** v0.3 anticipatory section said 4GB→6GB. D-050 fixes the asyncpg pool at min_size=1, max_size=10 (lower than the v0.3 anticipatory min_size=2). 6GB is confirmed sufficient. **Confidence 0.85** — the 6GB figure has ~50% margin.
|
||||
|
||||
### 1.2 docker-compose networking: internal bridge, service DNS, no external port
|
||||
|
||||
**Finding (0.92):** The current `docker-compose.yml` (verified — 49 lines, single `praxis` service, no explicit network → compose default bridge). v0.4 adds:
|
||||
|
||||
- An explicit named bridge network `praxis-net` (driver: bridge). **Not `internal: true`** — the postgres container doesn't need egress, but `internal: true` would also block DNS resolution from the praxis service. The simpler robust choice: named network, no `ports:` on postgres, no `internal: true`. The v0.3 research (`docs/RESEARCH-operator-postgres-auth.md` §1) confirmed this.
|
||||
- The `praxis` service joins `praxis-net` and gains `depends_on: { postgres: { condition: service_healthy } }`.
|
||||
- The `postgres` service joins `praxis-net`, no `ports:` mapping (not exposed to the LXC host bridge).
|
||||
- Service DNS: the praxis service reaches postgres via the service name `postgres` (Docker Compose internal DNS). DSN: `postgresql://praxis:${PRAXIS_PG_PASSWORD}@postgres:5432/praxis` (D-050).
|
||||
|
||||
**Migration note:** Adding an explicit network to the existing `praxis` service means compose recreates the praxis container on `up` (the default bridge → named network is a recreate trigger). Plan a ~5-15s downtime window. The SQLite volume (`praxis-data`) is untouched → learner state preserved. **Confidence 0.90** — standard Docker Compose behavior.
|
||||
|
||||
### 1.3 Persistent volume strategy
|
||||
|
||||
**Finding (0.90):** Named volume `pgdata` (driver: local) on the LXC rootfs. **Never bind-mount `/var/lib/postgresql/data` to the CT filesystem** — Postgres requires `chown 999` and a specific directory layout; named volumes handle this. Set `PGDATA=/var/lib/postgresql/data/pgdata` to pin the subdirectory (survives image upgrades). A separate mount is not warranted for the pilot — the LXC rootfs (16GB) has headroom, and a named volume keeps the data with the compose stack.
|
||||
|
||||
**Backups:** second named volume `pgbackups` (driver: local). Nightly `pg_dump -Fc` (custom compressed format) → `/backups/praxis-$(date +%u).sql.gz` (D-055). `%u` = day-of-week 1-7 → rolling 7-file retention with zero cleanup logic. Operator can `pct pull` backups to the PVE host for off-CT safety. **Confidence 0.85** — `pg_dump -Fc` is the documented Postgres backup format; `%u` retention is a standard cron pattern.
|
||||
|
||||
### 1.4 asyncpg connection pooling
|
||||
|
||||
**Finding (0.88):** asyncpg `create_pool(min_size=1, max_size=10, command_timeout=10)` on `app.state.pg_pool` via FastAPI `lifespan` context manager. D-050 fixes min_size=1 (lower than the v0.3 anticipatory min_size=2 — reduces idle connection overhead). Pool created on startup, closed on shutdown. Operator endpoints are low-frequency (cohort dashboard, VC issuance); max_size=10 is generous for v0.4 single-instance. The `PraxisStore` (aiosqlite) keeps its current per-call connect pattern — **pools are independent and must not be shared** (different backends, different lifecycles). `command_timeout=10` prevents a slow operator query from blocking the event loop.
|
||||
|
||||
**Statement cache:** asyncpg caches prepared statements per connection by default. With a small schema (5 tables) and parameterized queries, the cache is small and effective. No explicit `statement_cache_size` config needed at v0.4 scale.
|
||||
|
||||
**Pip:** `asyncpg>=0.29` (new dep — confirmed not in `pyproject.toml`).
|
||||
|
||||
### 1.5 pg_dump backup strategy (D-055)
|
||||
|
||||
**Finding (0.85):** Cron job inside the praxis container (or a sidecar one-shot) runs nightly:
|
||||
```
|
||||
pg_dump -U praxis -Fc praxis | gzip > /backups/praxis-$(date +%u).sql.gz
|
||||
```
|
||||
Wait — `pg_dump -Fc` already produces a compressed custom format; piping through gzip is redundant. The correct command is:
|
||||
```
|
||||
pg_dump -U praxis -Fc praxis -f /backups/praxis-$(date +%u).dump
|
||||
```
|
||||
This produces a compressed custom-format dump that `pg_restore` can selectively restore. **Drill:** `pg_restore --clean --if-exists /backups/praxis_3.dump` (drop+recreate objects, safe against partial DB). Never restore into the live DB without stopping the praxis service first.
|
||||
|
||||
The backup job runs via the in-process asyncio scheduler (same as the aggregation reconciliation job) OR via a host-side cron that `docker compose exec`s the pg_dump. The in-process approach is simpler (one scheduler for both nightly jobs) but couples backup to the praxis service lifecycle. **Recommend host-side cron** → `docker compose exec -T postgres pg_dump ...` so backups run even if praxis is down. **Confidence 0.80** — host-side cron decouples backup from app uptime.
|
||||
|
||||
### 1.6 Healthcheck for the Postgres service
|
||||
|
||||
**Finding (0.95):** `pg_isready -U praxis -d praxis` every 10s, 5 retries, 5s timeout. `depends_on: { postgres: { condition: service_healthy } }` on the praxis service. **Caveat:** `pg_isready` returns healthy before the DB is fully ready for migration load — the praxis app must still retry the first migration attempt (the pg_migrate runner should be idempotent + retry on connection failure).
|
||||
|
||||
### 1.7 Postgres 16 features used
|
||||
|
||||
**Finding (0.90):**
|
||||
- **`gen_random_uuid()`** — built into PG13+ core (no `pgcrypto` extension needed). Used as `DEFAULT gen_random_uuid()` for `operators.id`, `mastery_gate_events.id`, etc.
|
||||
- **Partitioning for `cohort_aggregates`** — PG16 supports declarative partitioning by `RANGE (window_start)`. Weekly partitions (one per ISO week) keep the table small per partition + enable fast windowed queries. **However, at v0.4 scale (<100 learners, ~weeks of data), partitioning is premature optimization.** The v0.3 anticipatory section mentioned "weekly partitions" but D-053 clarifies the dashboard reads pre-aggregated rows — the `cohort_aggregates` table is small (one row per `(path, metric, window_start)`). **Recommendation: ship a plain table with an index on `(path, window_start)`; add partitioning only if the table exceeds ~100K rows** (post-pilot). **This overturns the v0.3 anticipatory "weekly partitions" assumption** — see §8 v0.3 audit.
|
||||
|
||||

|
||||
|
||||
## Domain 2: Operator Auth — argon2id + Signed Cookies (D-041, D-056, D-057, REQ-NFR-AUTH-01)
|
||||
|
||||
### 2.1 argon2id parameters for v0.4 scale
|
||||
|
||||
**Finding (0.92):** OWASP Password Storage Cheat Sheet (fetched 2026-08-04) recommends Argon2id with one of these minimum configurations:
|
||||
- m=47104 (46 MiB), t=1, p=1
|
||||
- m=19456 (19 MiB), t=2, p=1
|
||||
- m=12288 (12 MiB), t=3, p=1
|
||||
- m=9216 (9 MiB), t=4, p=1
|
||||
- m=7168 (7 MiB), t=5, p=1
|
||||
|
||||
The `argon2-cffi` `PasswordHasher()` defaults are `time_cost=3, memory_cost=64MiB, parallelism=4` — **these exceed all OWASP minimums** (64MiB > 46MiB, t=3 matches the 12MiB/t=3 row, p=4 > p=1). The defaults are safe for a 6GB CT (64MiB per hash operation is trivial; login is low-frequency — one operator). **Recommendation: keep `PasswordHasher()` defaults.** Use `check_needs_rehash(stored_hash)` on login to rehash if params are bumped in the future. Benchmark login latency — if >1s, drop to `memory_cost=32MiB` (still exceeds OWASP minimums). **Confidence 0.92** — OWASP is the authoritative source; argon2-cffi defaults are documented.
|
||||
|
||||
### 2.2 Python argon2 library: argon2-cffi vs. passlib
|
||||
|
||||
**Finding (0.90):** **argon2-cffi** is the idiomatic choice for FastAPI. It's a thin CFFI wrapper around the reference Argon2 implementation, exposes `PasswordHasher` with argon2id as the default, and is actively maintained. `passlib` is a broader abstraction layer (supports multiple hash algorithms) but has had maintenance concerns (the 1.2 series hasn't seen a release in years; the 1.3 rewrite stalled). argon2-cffi is simpler, more focused, and the v0.3 research already chose it. **Pip: `argon2-cffi>=23.1`.** The v0.3 anticipatory architecture already lists `argon2-cffi` — confirmed.
|
||||
|
||||
### 2.3 Signed stateless cookies (HMAC-SHA256)
|
||||
|
||||
**Finding (0.88):** D-056 specifies "signed stateless cookies (HMAC-SHA256), no server-side session table." Starlette's `SessionMiddleware` uses `itsdangerous` under the hood, which signs the cookie with HMAC-SHA256 (via `TimestampedSigner`/`JSONWebSignature` depending on config). **The v0.3 anticipatory "SessionMiddleware (itsdangerous-signed)" framing is correct** — D-056's "HMAC-SHA256" is the underlying mechanism. The cookie is self-contained: `{operator_id, issued_at}` + HMAC signature. Verification = recompute HMAC + check expiry (8h). No `sessions` table in Postgres (D-056 explicit). Logout = client clears cookie (stateless — no server revocation list in v0.4).
|
||||
|
||||
**Key management:** `SECRET_KEY` from env (`PRAXIS_COOKIE_SECRET`, ≥32 bytes random). Rotation = change the key (invalidates all sessions — acceptable for a pilot). **Confidence 0.88** — Starlette SessionMiddleware is the documented FastAPI session pattern.
|
||||
|
||||
**Cookie attributes:**
|
||||
- `session_cookie`: `"praxis_op"` (distinct from any future learner cookie)
|
||||
- `max_age`: `28800` (8h, per D-041)
|
||||
- `httponly`: `True` (middleware default; verify)
|
||||
- `samesite`: `"strict"` (D-041 — CSRF defense-in-depth)
|
||||
- `secure`: **config-driven** (see §2.4 below)
|
||||
- `path`: `/` (or scope to `/api/operator` — cleaner, but the React `/operator/*` routes also need the cookie for the `/api/operator/me` call on mount; use `/`)
|
||||
|
||||
### 2.4 Secure cookie + no-TLS pilot tension (R-AUTH-01 resolution)
|
||||
|
||||
**Finding (0.75):** D-030 (no Traefik/TLS for pilot) conflicts with the `Secure` cookie attribute (browsers reject `Secure` cookies over HTTP, or rather: they don't send them over HTTP). The three options:
|
||||
|
||||
**(a) Config-driven `Secure` flag (RECOMMENDED):**
|
||||
- `PRAXIS_COOKIE_SECURE` env var (default `true`).
|
||||
- For the HTTP pilot: set `PRAXIS_COOKIE_SECURE=false`, log a WARNING, document the risk in GRILL-v0.4.md.
|
||||
- When TLS is added later (post-v0.4), flip the env var → cookies become Secure automatically.
|
||||
- **Defense in depth:** the cohort dashboard reads only k-anonymized aggregates (D-034) → even a cookie sniffed over HTTP leaks no PII. The VC issuance endpoints are auth-gated but the credentials themselves are public (verification endpoint is unauthenticated per D-043).
|
||||
|
||||
**(b) Accept the pilot risk + document:**
|
||||
- Same as (a) but without the config flag — hardcode `secure=False` for v0.4.
|
||||
- **Rejected:** inflexible — requires code change when TLS arrives.
|
||||
|
||||
**(c) Minimal TLS via Caddy/nginx sidecar:**
|
||||
- Add a 3rd Docker service (Caddy reverse proxy) with a self-signed cert.
|
||||
- **Rejected:** breaks D-030's "direct bridge IP access" pilot stance, adds a 3rd service + cert management, self-signed certs trigger browser warnings (worse UX than plain HTTP for a pilot). Defer to a later milestone.
|
||||
|
||||
**Verdict: option (a).** The config-driven flag is the safest minimal path — no new infra, automatic upgrade when TLS arrives, explicit risk documentation. **Confidence 0.75** — the resolution is sound but the pilot HTTP risk is real; the grill must sign off.
|
||||
|
||||
### 2.5 Login rate limiting (5 attempts/min)
|
||||
|
||||
**Finding (0.78):** D-041 specifies 5 attempts/min. Two implementations:
|
||||
|
||||
1. **slowapi** (`slowapi>=0.1`) — idiomatic FastAPI rate limiter. `@limiter.limit("5/minute")` on the login route. In-memory backend (per-process). **Caveat:** breaks if >1 praxis process (not a v0.4 concern — single uvicorn). Confidence 0.70 — young lib, but works.
|
||||
|
||||
2. **In-memory counter** — `dict[remote_ip, (count, window_start)]` in a FastAPI dependency. Zero deps, trivially auditable. For a single operator login endpoint, this is sufficient. Confidence 0.80 for the pilot.
|
||||
|
||||
**Recommendation: slowapi** for idiomaticity (decorator pattern, well-documented). The hand-rolled counter is the documented fallback if slowapi causes issues. Threshold: 5 failed attempts/minute/IP → 429 + `Retry-After` header. **Pip: `slowapi>=0.1`.** Rate limit is on the *login* route only (not the auth-gated routes — those check the cookie).
|
||||
|
||||
### 2.6 Session expiry (8h) + renewal strategy
|
||||
|
||||
**Finding (0.85):** `max_age=28800` (8h) on the cookie. No sliding renewal in v0.4 — the cookie expires 8h after issuance. The operator re-logs in after 8h. **Renewal is deferred** — a later milestone could implement sliding renewal (re-issue on activity) if 8h is too short for operator workflows. For v0.4 (single operator, low-frequency dashboard reads), 8h fixed is sufficient. **Confidence 0.85.**
|
||||
|
||||

|
||||
|
||||
## Domain 3: Cohort Aggregation — k-anonymity + 7-day windows (D-034, D-045, D-053, D-054)
|
||||
|
||||
### 3.1 k-anonymity ≥ 10 enforcement at write time
|
||||
|
||||
**Finding (0.85):** D-034 + REQ-NFR-DASH-01. The aggregation SQL enforces k≥10 via cell suppression at write time (not read time — auditable). Pattern:
|
||||
|
||||
```sql
|
||||
-- Pseudo-SQL — shape only
|
||||
INSERT INTO cohort_aggregates (path, metric, window_start, window_end, value, cell_count, cell_suppressed)
|
||||
SELECT
|
||||
path,
|
||||
metric,
|
||||
window_start,
|
||||
window_end,

|

cell_suppressed = excluded.cell_suppressed,
|

updated_at = now();
|
||||
```
|
||||
|
||||
- `cell_suppressed = TRUE` + `value = NULL` for cells < 10 learners.
|
||||
- The dashboard renders suppressed cells as "— (suppressed, <10 learners)" — transparent to the operator.
|
||||
- **Differencing attacks:** limited to pre-defined 2-D views (path × week, path × outcome) per the v0.3 anonymization research. No arbitrary filters (no per-learner drill-down — D-053 explicit).
|
||||
|
||||
**Confidence 0.85** — k-anonymity via `COUNT(DISTINCT) >= K` is the textbook suppression pattern.
|
||||
|
||||
### 3.2 7-day rolling window aggregation SQL
|
||||
|
||||
**Finding (0.82):** The `cohort_aggregates` table stores rows keyed by `(path, metric, window_start)`. Each row represents one 7-day window starting at `window_start`. The aggregation job (on-session-end hook + nightly) upserts by `(path, metric, window_start)` — idempotent. The 7-day window is a rolling construct: the nightly job recomputes the current window (the one containing "today") + the previous window (for continuity). On read, the dashboard queries `WHERE window_start >= now()::date - interval '7 days'` for the current view.
|
||||
|
||||
**Materialized view vs. incremental upsert:** Incremental upsert wins at v0.4 scale. A materialized view requires `REFRESH MATERIALIZED VIEW` (locks the view, slow at scale) and doesn't support partial refresh. Incremental upsert is cheap (one row per `(path, metric, window_start)`) + idempotent + supports the on-session-end hook pattern. **Confidence 0.82.**
|
||||
|
||||
### 3.3 On-session-end hook — async fire-and-forget (D-054)
|
||||
|
||||
**Finding (0.85):** D-054 confirms. The existing `SessionRecorder.end()` (line 142-145 of `session_recorder.py`) already schedules the mastery flow via `asyncio.create_task(self._run_mastery_flow_guarded(mastery_deps))`. The v0.4 aggregation hook follows the same pattern — chained after the mastery flow completes (or in parallel, since the aggregation only needs the session outcome + rubric scores, which the mastery flow produces). The hook:
|
||||
|
||||
1. Reads the session outcome + rubric scores from the mastery flow result (or directly from the SQLite `mastery_gate_events` table).
|
||||
2. Computes the k-anonymized aggregate for the affected `(path, metric, window_start)` bin.
|
||||
3. Upserts to Postgres `cohort_aggregates` (idempotent).
|
||||
4. Failures log + the nightly job reconciles.
|
||||
|
||||
**Lifecycle:** `asyncio.Task` — non-blocking, the session-end response returns immediately. If the service restarts, the in-flight task is lost but nightly reconciliation covers it (D-054 explicit). **Confidence 0.85** — the pattern is already proven in the codebase.
|
||||
|
||||
### 3.4 Nightly reconciliation job
|
||||
|
||||
**Finding (0.80):** D-054 specifies 03:00 CT. Two implementation options:
|
||||
|
||||
1. **In-process asyncio scheduler** — `asyncio.create_task` loop with `asyncio.sleep` until 03:00 CT. No extra dep. If the service restarts, the scheduler resumes on startup (computes next 03:00). Simple, matches the "no Celery/Redis for v0.4" stance.
|
||||
2. **APScheduler** — `apscheduler>=3.10` with a `AsyncIOScheduler`. More features (cron expressions, job stores) but over-engineered for one nightly job.
|
||||
|
||||
**Recommendation: in-process asyncio scheduler.** One `asyncio.create_task` that loops: compute seconds until next 03:00 CT → `asyncio.sleep(seconds)` → run reconciliation → repeat. The reconciliation job recomputes all 7-day windows for all paths (idempotent upsert). **Confidence 0.80** — simple, no dep, but no retry-on-failure (if the job fails, it retries the next night; the on-session-end hook keeps data fresh in the meantime).
|
||||
|
||||
### 3.5 Metrics for the 3 dashboard views (D-053)
|
||||
|
||||
**Finding (0.82):** D-053 names three views. Concrete metrics per view:
|
||||
|
||||
| View | Metrics (k-anonymized, 7-day windows) |
|
||||
|------|---------------------------------------|
|
||||
| **Practice volume** | sessions/day per path; total sessions in window; active learners in window (suppressed if <10) |
|
||||
| **Mastery progression** | % learners at each week (1-6); gate-open rate (gate_opened / total_gate_events); median mastery_score; rubric criterion mean scores (per criterion, across path) |
|
||||
| **Failure patterns** | top failure_modes by frequency; rubric criterion weak-spots (criteria with mean < 3.0); branch outcome distribution (escalate vs accept) |
|
||||
|
||||
Each metric is a row in `cohort_aggregates` with `(path, metric, window_start, window_end, value, cell_count, cell_suppressed)`. The `/api/operator/<view>` endpoint returns the pre-aggregated rows for that view's metrics.
|
||||
|
||||
### 3.6 No raw learner PII in Postgres (D-031 hybrid)
|
||||
|
||||
**Finding (0.90):** D-031 hybrid — learner-local state stays SQLite; operator-tier Postgres stores only aggregations + operator accounts + issued credentials. **What identifies a learner?** `learner_ref` — an opaque string (e.g., `"learner-1"`, the existing `HARDCODED_LEARNER_ID`). The Postgres tables (`cohort_aggregates`, `mastery_gate_events`, `issued_credentials`) use `learner_ref` as the join handle — **never** a FK to SQLite (cross-DB joins are impossible). The existing `issued_credentials` table in SQLite uses `learner_id` (the hardcoded string); v0.4's Postgres `issued_credentials` table uses `learner_ref` (same opaque string, different column name to emphasize it's not a FK). **Confidence 0.90** — D-031 is explicit; the codebase already uses opaque string IDs.
|

||||
|
||||
## Domain 4: React Cohort Dashboard (D-044, D-053, REQ-DASH-01)
|
||||
|
||||
### 4.1 React route under `/operator/*`
|
||||
|
||||
**Finding (0.85):** D-044. The existing client (`client/src/App.tsx`) is a single-view state machine (start → live → debrief) with **no React Router**. v0.4 adds:
|
||||
|
||||
- A new `client/src/operator/` directory with the cohort dashboard components.
|
||||
- React Router (or a minimal route switch) for `/operator/*` routes: `/operator/login`, `/operator/dashboard`.
|
||||
- The existing `App.tsx` remains the voice session UI at `/`.
|
||||
|
||||
**Routing structure:** The current `App.tsx` is mounted at `/` by the StaticFiles serving. Adding `/operator/*` routes requires either:
|
||||
- **(a) React Router** — `npm install react-router-dom` + a `<BrowserRouter>` wrapper. The StaticFiles `html=True` mount serves `index.html` for all paths, React Router handles client-side routing. **Caveat:** the existing `App.tsx` doesn't use React Router; wrapping it requires a refactor (or a separate root).
|
||||
- **(b) Minimal route switch** — `useState<'voice' | 'operator'>` based on `window.location.pathname.startsWith('/operator')`. No new dep. Simpler, but less idiomatic for a growing dashboard.
|
||||
|
||||
**Recommendation: React Router** (`react-router-dom@^7`) — it's the standard, supports nested routes, and the v0.4 dashboard will grow (D-053 names 3 views). The refactor to wrap `App.tsx` in a `<BrowserRouter>` is small. Add a catch-all route that serves the voice UI at `/` and the operator UI at `/operator/*`. **Pip: none; npm: `react-router-dom`.** **Confidence 0.80** — React Router is standard but adds a dep + a refactor of the existing single-view App.
|
||||
|
||||
**SPA fallback:** With React Router, the FastAPI StaticFiles mount needs to serve `index.html` for all non-API paths (SPA fallback). The current `app.mount("/", StaticFiles(directory=_CLIENT_DIST, html=True))` serves `index.html` for `/` but returns 404 for `/operator/dashboard` (no such file). **This is a required change:** add a catch-all route before the StaticFiles mount that returns `FileResponse("client/dist/index.html")` for any path not matching an API route. The v0.2 RESEARCH.md Q3 noted this as "NOT needed for v0.2" — v0.4 needs it. **Confidence 0.90** — standard SPA serving pattern.
|
||||
|
||||
### 4.2 Reusing v0.2 StaticFiles (same `client/dist` build)
|
||||
|
||||
**Finding (0.90):** D-044 explicit. No separate SPA build — the same `npm run build` produces `client/dist` with both the voice UI and the operator dashboard. The Dockerfile's Node stage is unchanged (one `npm run build`). The FastAPI StaticFiles mount is updated to serve the SPA fallback (see §4.1). **Confidence 0.90.**
|
||||
|
||||
### 4.3 Read-only tables + sparkline charts
|
||||
|
||||
**Finding (0.80):** The dashboard renders read-only tables + sparkline charts. **No chart library is in `client/package.json`** (verified — only react, react-dom, pipecat client SDK, dev deps). Options:
|
||||
|
||||
1. **Inline SVG sparklines** (~50 LOC, zero deps) — a `<Sparkline data={...} />` component that renders an SVG polyline. Sufficient for k-anon tables (small data: one sparkline per row, ~7-30 data points). **Recommendation for v0.4.**
|
||||
2. **uPlot** (~40KB, sparkline-native, no React dependency) — high-performance, but overkill for small tables.
|
||||
3. **Recharts** (~100KB, React-native) — idiomatic but heavy for sparklines.
|
||||
4. **Chart.js + react-chartjs-2** (~200KB) — heaviest, overkill.
|
||||
|
||||
**Recommendation: inline SVG sparklines** (zero deps, ~50 LOC, sufficient for v0.4 scale). Add a chart library only if the dashboard grows to need axes, tooltips, zoom. **Confidence 0.80** — sparklines are simple; the inline SVG approach is well-documented.
|
||||
|
||||
### 4.4 `/api/operator/*` FastAPI endpoint structure
|
||||
|
||||
**Finding (0.88):** D-053 + D-057. New `server/operator/` module with an `APIRouter(prefix="/api/operator")`. Endpoints:
|
||||
|
||||
| Endpoint | Method | Auth | Purpose |
|
||||
|----------|--------|------|---------|
|
||||
| `/api/operator/login` | POST | rate-limited (5/min) | Login: validate argon2id, set signed cookie |
|
||||
| `/api/operator/logout` | POST | auth-gated | Clear cookie (client-side) |
|
||||
| `/api/operator/me` | GET | auth-gated | Return current operator (for React route guard) |
|
||||
| `/api/operator/cohort` | GET | auth-gated | Practice volume view (k-anonymized) |
|
||||
| `/api/operator/mastery` | GET | auth-gated | Mastery progression view (k-anonymized) |
|
||||
| `/api/operator/failure-patterns` | GET | auth-gated | Failure patterns view (k-anonymized) |
|
||||
| `/api/operator/credentials` | GET | auth-gated | List issued VCs (operator's issuance log) |
|
||||
| `/api/operator/credentials/{id}/revoke` | POST | auth-gated | Revoke a VC |
|
||||
|
||||
Auth enforcement: FastAPI middleware checks the signed cookie on every `/api/operator/*` request (D-057); 401 if missing/invalid/expired. Router-level `dependencies=[Depends(current_operator)]` on the protected routes. Login + logout are outside the protected router (login is rate-limited, not auth-gated). **Confidence 0.88.**
|
||||
|
||||
### 4.5 Freshness ≤ 24h (REQ-NFR-DASH-02)
|
||||
|
||||
**Finding (0.85):** The on-session-end hook keeps aggregates fresh within minutes of a session ending. The nightly reconciliation job (03:00 CT) guarantees all 7-day windows are recomputed at least once/day. **Max staleness = 24h** (if the service restarts after a session and before the nightly job, the aggregate is stale until the next 03:00 run). The dashboard surfaces "last updated" via a `updated_at` timestamp on each `cohort_aggregates` row → the `/api/operator/<view>` response includes `last_updated: max(updated_at)` across the returned rows. React renders "Last updated: Xh ago" in the dashboard header. **Confidence 0.85.**
|
||||

|

## Domain 5: VC Issuer Key Migration (D-042, D-051)
|
||||
|
||||
### 5.1 Migrating the Ed25519 issuer key from SQLite to Postgres
|
||||
|
||||
**Finding (0.88):** D-051. The existing `server/vc/issuer_keys.py` (verified — 128 lines) implements the issuer key lifecycle:
|
||||
- `init_issuer_key(store, root_key)` — generates a fresh Ed25519 keypair, encrypts the private key with `nacl.SecretBox` (root key from `PRAXIS_VC_ISSUER_KEY` env), stores in the `issuer_keys` table.
|
||||
- `get_active_signing_key(store, root_key)` — returns the active key (status='active'), or generates one if none exists.
|
||||
- `get_public_key_for_verification(store, key_id)` — returns the public key for a given key_id (queries by id, not by status — **this is the fallback mechanism**).
|
||||
- `rotate_key(store, root_key)` — generates a new key, marks the old as `superseded`.
|
||||
- `_verification_method(key_id)` — builds the `verificationMethod` URL.
|
||||
|
||||
v0.4 migration:
|
||||
1. The `issuer_keys.py` functions currently take a `PraxisStore` (SQLite). v0.4 adds a `PgStore` (Postgres) and the issuer key functions are refactored to accept either store (or a dedicated `IssuerKeyStore` interface). **The simplest refactor:** the issuer key functions accept a protocol/ABC with `init_issuer_key`, `get_active_signing_key_row`, `get_public_key_row`, `set_issuer_key_superseded` methods — both `PraxisStore` (SQLite) and `PgStore` (Postgres) implement it.
|
||||
2. On first v0.4 boot: generate a fresh keypair in Postgres `issuer_keys` (status='active').
|
||||
3. **Archive the v0.3 public key** — read the v0.3 active key's public key from SQLite, insert it into Postgres `issuer_keys` with status='superseded'. The private key is NOT migrated (v0.3 VCs are already signed; verification only needs the public key).
|
||||
4. The verification endpoint (`server/vc/verification.py:verify_credential`) extracts `key_id` from the proof's `verificationMethod` and calls `get_public_key_for_verification(store, key_id)`. **The fallback to superseded keys is already implicit** — `get_public_key_row(key_id)` queries by id, not by status. v0.3 VCs have the v0.3 key_id in their proof → the lookup finds the archived (superseded) public key → signature verifies.
|
||||
|
||||
**Confidence 0.88** — the existing code already supports the lifecycle; the migration is a store swap + an archive insert.
|
||||
|
||||
### 5.2 Archiving the v0.3 public key as `superseded` (not revoked)
|
||||
|
||||
**Finding (0.90):** D-051 explicit. The v0.3 public key is archived as `superseded` — old VCs still verify against it. **Revoked** would imply the key is no longer trusted (old VCs should fail verification). **Superseded** means the key is no longer used for new signatures but old signatures remain valid. The existing `set_issuer_key_superseded(key_id)` method (line 348-354 of `store.py`) does exactly this. **Confidence 0.90.**
|
||||
|
||||
### 5.3 Verification endpoint fallback
|
||||
|
||||
**Finding (0.88):** The verification flow (`server/vc/verification.py`):
|
||||
1. `verify_credential(store, credential_id)` → fetches the credential row.
|
||||
2. `extract_key_id(secured_doc)` → extracts key_id from the proof's `verificationMethod` URL.
|
||||
3. `get_public_key_for_verification(store, key_id)` → fetches the public key by id.
|
||||
4. `verify_proof(secured_doc, verify_key)` → validates the Ed25519 signature.
|
||||
|
||||
The fallback is implicit: step 3 queries by `key_id` (not by status), so it finds both active and superseded keys. v0.3 VCs have v0.3 key_ids → step 3 finds the archived (superseded) public key → step 4 validates. **No code change needed in the verification flow** — only the store backing changes (SQLite → Postgres). **Confidence 0.88.**
|
||||
|
||||
### 5.4 Encrypted-at-rest private key in Postgres
|
||||
|
||||
**Finding (0.85):** The existing `_encrypt_private_key(signing_key, root_key)` uses `nacl.SecretBox` with a root key from `PRAXIS_VC_ISSUER_KEY` env. This is application-layer encryption — the private key is encrypted before being stored in the DB. The same pattern works for Postgres (the `private_key_enc` column is `BYTEA`). **Postgres-level encryption at rest** (TDE) is not available in the open-source Postgres 16 (that's an EnterpriseDB feature). The application-layer `nacl.SecretBox` is the correct approach for the pilot. The root key (`PRAXIS_VC_ISSUER_KEY`) is in `.env.secrets` (gitignored). **Confidence 0.85** — the pattern is already proven in v0.3; the store swap is mechanical.
|
||||

|
||||
## Domain 6: Operator Account Bootstrap (D-052)
|
||||
|
||||
### 6.1 `scripts/create-operator.py` CLI script
|
||||
|
||||
**Finding (0.88):** D-052. A new `scripts/create-operator.py` script:
|
||||
- Reads `PRAXIS_BOOTSTRAP_OPERATOR_USER` + `PRAXIS_BOOTSTRAP_OPERATOR_PASS` from env (in `.env.secrets`).
|
||||
- Hashes the password with `argon2-cffi` `PasswordHasher().hash(password)`.
|
||||
- Connects to Postgres via asyncpg.
|
||||
- Inserts into `operators` table: `INSERT INTO operators (username, password_hash, display_name) VALUES ($1, $2, $3) ON CONFLICT (username) DO NOTHING`.
|
||||
- Idempotent — no-op if the user exists (no password update on re-run; a separate `--update` flag could force a rehash if needed).
|
||||
- Prints the result: `created` or `already exists`.
|
||||
|
||||
**Running the script:** `docker compose exec praxis python scripts/create-operator.py` (from the host) or directly in the CT. The script reads env vars from the praxis container's environment (which sources `/etc/praxis/server.env`). **Confidence 0.88.**
|
||||
|
||||
### 6.2 Env vars in `.env.secrets`
|
||||
|
||||
**Finding (0.90):** D-052. `PRAXIS_BOOTSTRAP_OPERATOR_USER` + `PRAXIS_BOOTSTRAP_OPERATOR_PASS` added to `.ciagent/.env.secrets` (gitignored — verified in `.gitignore`). These are injected via `lxc.environment` → `/etc/praxis/server.env` → `docker-compose.yml` env_file → container env. The `config.json` secrets scopes need a new `operator` scope with these vars. **Confidence 0.90** — the secret injection chain is proven from v0.2.

## Domain 7: Persona Assessment (v0.4 roster)
|
||||
|
||||
### 7.1 Active personas for v0.4
|
||||
|
||||
**Finding (0.90):** v0.4 is **operator-tier-backend + dashboard-frontend + security-crypto + Postgres-in-LXC**. The roster:

## Consolidated Risks Table
|
||||
|
||||
| ID | Risk | Severity | Mitigation | Confidence |
|
||||
|----|------|----------|------------|------------|
|
||||
| **R-MT-01** | Postgres + praxis resource contention on 6GB CT (disk I/O during nightly pg_dump + aggregation) | medium | Schedule nightly jobs at 03:00 CT (low learner activity); aggregation is incremental upsert (not full scan); monitor CT memory; bump to 8GB if OOM | 0.75 |
|
||||
| **R-MT-02** | Postgres container unhealthy on boot → praxis `depends_on` blocks startup | medium | `pg_isready` healthcheck + 5 retries; praxis app retries first migration on connection failure; `depends_on: service_healthy` is necessary but not sufficient | 0.80 |
|
||||
| **R-MT-03** | Docker Compose network change (default bridge → praxis-net) recreates praxis container → ~5-15s downtime | low | Plan cutover window; SQLite volume untouched → learner state preserved; do on staging CT first | 0.85 |
|
||||
| **R-MT-04** | `pgdata` volume corruption on CT restart (LXC + Docker volume interaction) | low | Named volumes are stable on Docker-in-LXC with nesting=1; nightly pg_dump provides backup; `pg_restore --clean --if-exists` drill | 0.70 |
|
||||
| **R-MT-05** | Postgres 16 `gen_random_uuid()` not available (misremembered as PG13+) | low | Verified: `gen_random_uuid()` is built into PG13+ core (no extension). PG16 confirmed. | 0.95 |
|
||||
| **R-AUTH-01** | Secure cookie flag + no-TLS pilot → cookies sent over HTTP (sniffable) | medium | Config-driven `PRAXIS_COOKIE_SECURE` (default true; false for HTTP pilot with logged WARNING); cohort dashboard reads only k-anonymized aggregates (no PII leak even if cookie sniffed); grill must sign off | 0.75 |
|
||||
| **R-AUTH-02** | argon2id hashing blocks event loop (CPU-bound, ~30-80ms per login) | low | Single operator login is low-frequency; ~80ms is acceptable on the event loop. If batch-hashing needed, use `run_in_executor`. Not a v0.4 concern. | 0.85 |
|
||||
| **R-AUTH-03** | In-memory rate limit lost on service restart (attacker bypasses by timing restart) | low | Single-instance pilot; restarts are rare + operator-initiated. A persistent rate-limit store (Redis) is deferred. | 0.80 |
|
||||
| **R-AUTH-04** | Signed cookie secret (`PRAXIS_COOKIE_SECRET`) rotation invalidates all sessions | low | Pilot: acceptable (one operator re-logs in). Document the rotation procedure. | 0.85 |
|
||||
| **R-AUTH-05** | No server-side session revocation (logout is client-side only) | low | D-056 explicit: stateless cookies, no revocation list in v0.4. A forced-logout requires cookie secret rotation. Deferred to a later milestone. | 0.80 |
|
||||
| **R-DASH-01** | k-anonymity suppression hides meaningful data at v0.4 scale (<100 learners → many cells <10) | medium | Expected at pilot scale; dashboard shows "— (suppressed, <10 learners)" transparently. Aggregation window can be widened (14-day) if too many cells suppressed. | 0.75 |
|
||||
| **R-DASH-02** | Differencing attack: operator compares two 7-day windows to isolate a single learner | medium | Limit to pre-defined 2-D views (path × week, path × outcome); no arbitrary filters; no per-learner drill-down (D-053). | 0.70 |
|
||||
| **R-DASH-03** | SPA fallback breaks existing voice UI (StaticFiles mount change) | medium | Add catch-all route BEFORE StaticFiles mount; test `/` still serves voice UI; test `/operator/dashboard` serves index.html. | 0.80 |
|
||||
| **R-DASH-04** | Nightly reconciliation job fails → aggregates stale >24h (NFR-DASH-02 breach) | low | On-session-end hook keeps data fresh; job retries next night; log + alert on job failure. | 0.75 |
|
||||
| **R-DASH-05** | React Router addition requires App.tsx refactor → breaks voice UI | medium | Wrap App.tsx in `<BrowserRouter>` with a catch-all route; test voice UI at `/` unchanged. | 0.75 |
|
||||
| **R-VC-MIG-01** | VC issuer key migration loses v0.3 public key → old VCs fail verification | high | Archive v0.3 public key as `superseded` in Postgres `issuer_keys` before activating new key; verification endpoint queries by key_id (not status) → fallback is implicit. Test: verify a v0.3 VC against the migrated store. | 0.85 |
|
||||
| **R-VC-MIG-02** | `PRAXIS_VC_ISSUER_KEY` root key changes between v0.3 and v0.4 → encrypted private keys undecryptable | medium | The v0.3 private key is NOT migrated (only the public key is archived). The v0.4 active key is generated fresh with the v0.4 root key. Keep the v0.3 root key in secrets until all v0.3 VCs expire (3-year validUntil). | 0.80 |
|
||||
| **R-VC-MIG-03** | `issuer_keys.py` store refactor (SQLite→Postgres protocol) breaks v0.3 verification | medium | Define an `IssuerKeyStore` protocol/ABC; both `PraxisStore` and `PgStore` implement it; verification endpoint uses the Postgres store for v0.4. Test: verify a v0.3 VC against the Postgres store with the archived public key. | 0.80 |
|
||||
| **R-BOOT-01** | `create-operator.py` fails on first boot (Postgres not ready) | low | Script retries on connection failure (3 attempts, 5s backoff); run after `docker compose up -d postgres` + healthcheck passes. | 0.80 |
|
||||
| **R-BOOT-02** | `PRAXIS_BOOTSTRAP_OPERATOR_PASS` not set → operator can't log in | low | Script checks env var presence + exits with clear error if missing. Document in `.env.example`. | 0.85 |

## v0.3 Assumption Audit (which anticipatory assumptions were confirmed / overturned)
|
||||
|
||||
The v0.3 ARCHITECTURE.md operator-tier section was anticipatory. D-050..D-057 (v0.4 clarify decisions) refine it. Audit:
|
||||
|
||||
| v0.3 anticipatory assumption | v0.4 decision | Verdict |
|
||||
|------------------------------|---------------|---------|
|
||||
| `postgres:16-slim`, named volume `pgdata`, internal network, `pg_isready` healthcheck | D-040, D-050 confirmed | **CONFIRMED** |
|
||||
| asyncpg `create_pool(min_size=2, max_size=10)` | D-050: `min_size=1` | **OVERTURNED** — D-050 lowers min_size to 1 (lower idle cost) |
|
||||
| Starlette `SessionMiddleware` (itsdangerous-signed) | D-056: signed stateless cookies (HMAC-SHA256) | **CONFIRMED** — SessionMiddleware uses itsdangerous/HMAC-SHA256 under the hood; D-056 is the mechanism clarification |
|
||||
| argon2-cffi `PasswordHasher` defaults | D-041 + OWASP: defaults exceed minimums | **CONFIRMED** — keep defaults (time_cost=3, memory_cost=64MiB, parallelism=4) |
|
||||
| slowapi 5/min login rate-limit | D-041 + D-057 | **CONFIRMED** — slowapi is the idiomatic choice; in-memory counter is the fallback |
|
||||
| `cohort_aggregates` with weekly partitions | D-053: pre-aggregated rows, 7-day rolling windows | **OVERTURNED** — weekly partitions are premature at v0.4 scale; ship a plain table with `(path, window_start)` index. Add partitioning post-pilot. |
|
||||
| `operators`, `issued_credentials`, `mastery_gate_events`, `cohort_aggregates`, `issuer_keys` tables | D-050..D-053 confirmed | **CONFIRMED** — schema holds; column names refined (learner_ref vs learner_id) |
|
||||
| CT memory 4GB → 6GB | D-050 + REQ-NFR-MT-01 | **CONFIRMED** — 6GB is sufficient |
|
||||
| `pg_dump -Fc` to `pgbackups` volume, `%u` 7-file retention | D-055 confirmed | **CONFIRMED** — but host-side cron (not in-process) for decoupling |
|
||||
| Secure cookie requires TLS (R-AUTH-01) | D-056 + D-030: config-driven `Secure` flag | **REFINED** — config-driven flag is the v0.4 resolution; v0.3 flagged it as an open question |
|
||||
| VC issuer key in Postgres `issuer_keys` (encrypted at rest) | D-042 + D-051 confirmed | **CONFIRMED** — plus the migration path (archive v0.3 public key as superseded) |
|
||||
| `gen_random_uuid()` in PG16 (no extension) | Verified | **CONFIRMED** |
|
||||
| React `/operator/*` route, reuses v0.2 StaticFiles | D-044 + D-053 confirmed | **CONFIRMED** — plus SPA fallback requirement (new) |
|
||||
| on-session-end hook + nightly reconciliation | D-045 + D-054 confirmed | **CONFIRMED** — D-054 clarifies async fire-and-forget + 03:00 CT |
|
||||
|
||||
**Summary:** 2 overturned (asyncpg min_size, weekly partitions), 1 refined (Secure cookie → config-driven), 11 confirmed.

|
||||
|
||||
## Open Questions for PLAN Stage
|
||||
|
||||
1. **SPA fallback implementation:** Catch-all route before StaticFiles mount, or a custom StaticFiles subclass? The catch-all route is simpler but must not shadow `/api/*` or `/vc/*` routes.
|
||||
2. **`IssuerKeyStore` protocol design:** ABC with methods, or a simpler duck-typing approach? The existing `PraxisStore` methods (`init_issuer_key`, `get_active_signing_key_row`, `get_public_key_row`, `set_issuer_key_superseded`) are the interface.
|
||||
3. **Nightly scheduler:** In-process asyncio loop or host-side cron for the aggregation job? (pg_dump backup is host-side cron.) In-process is simpler for aggregation (shares the asyncpg pool); host-side is better for backup (decoupled from app uptime).
|
||||
4. **`create-operator.py` update path:** `--update` flag to force rehash, or a separate `scripts/update-operator.py`? Keep it simple: `--update` flag on the same script.
|
||||
5. **Cookie `path` scope:** `/` (cookie sent to all routes) or `/api/operator` (cookie sent only to operator API)? `/` is needed for the React `/operator/*` routes to call `/api/operator/me` on mount (the browser sends the cookie). Use `/`.
|
||||
6. **Cohort aggregation `learner_ref` source:** The existing `HARDCODED_LEARNER_ID = "learner-1"` — is this stable enough for the aggregation? Yes for v0.4 (single learner); multi-learner-per-device is deferred. The aggregation groups by `learner_ref` so k-anonymity counts distinct learners.
|
||||
7. **Phase split confirmation:** ROADMAP shows P1 (operator foundation: Postgres + auth) → P2 (cohort dashboard + aggregation) → P3 (review). Is the aggregation pipeline P1 or P2? D-045 + D-054 suggest the hook is P2 (needs the dashboard to be useful), but the Postgres schema + the on-session-end hook could be P1. **Recommendation:** P1 = Postgres + auth + VC key migration + schema (including `cohort_aggregates` table); P2 = aggregation pipeline (hook + nightly job) + dashboard UI + endpoints. The schema is P1 so P2 is pure code.

This document grounds the v0.3 verifiable-credential issuer in ecosystem evidence. It answers the 7 research questions and concludes with concrete pip-installable recommendations and a risks/unknowns list for the PLAN stage. Decisions D-033 (W3C VC 2.0, platform-issued, Ed25519), D-042 (issuer key in operator secrets), and D-043 (public verification endpoint) are assumed fixed; this research validates them and fills in implementation detail.

## Summary of Findings (Executive 1-Pager)
|
||||
|
||||
1. **VC Data Model 2.0 is a W3C Recommendation (15 May 2025).** Not a draft — it is the current stable standard. VC-DM 1.1 is superseded. Key 2.0 changes: `issuanceDate`/`expirationDate` → `validFrom`/`validUntil`; JSON-LD `@context` first item MUST be `https://www.w3.org/ns/credentials/v2`; media types `application/vc` and `application/vp` are now registered; securing mechanisms (Data Integrity proofs + JOSE/COSE) are separated into companion specs. (Confidence: 0.98)
|
||||
|
||||
2. **No production-ready *pure-Python* "VC library" exists for issuing+verifying.** `py-vc` and `did-jwt` are JavaScript/JS-ecosystem; `vc-js` is JS. The Python ecosystem is fragmented: `pyld` (JSON-LD processor), `rdf-canonicalize` (RDF canonicalization), `pynacl` (Ed25519 crypto), `base58`/`canonicaljson` (encodings). **Recommendation: assemble from primitives** — `pynacl` + `canonicaljson` (or `jcs`) + `base58` + hand-rolled `eddsa-jcs-2022` proof wrapper (~200 LOC). This is the simplest viable path and avoids the RDF-canonicalization complexity that `eddsa-rdfc-2022` requires. (Confidence: 0.80)
|
||||
|
||||
3. **Bitstring Status List v1.0 is a W3C Recommendation (15 May 2025)** — same day as VC-DM 2.0. It is fully implementable without a third-party service: the issuer publishes a single GZIP-compressed, Multibase-encoded bitstring as a `BitstringStatusListCredential` at a stable URL. Minimum 131,072-bit (16 KB uncompressed) list for herd privacy; a few hundred bytes compressed when few credentials are revoked. Single-issuer MVP = one status list URL + one bit per credential. (Confidence: 0.95)
|
||||
|
||||
4. **Ed25519 signing: use `pynacl` (1.6.2, libsodium 1.0.20, Apache-2.0, maintained by Python Cryptographic Authority).** Not `ed25519` (PyPI — unmaintained since 2016) and not `ed25519-zebra` (that's Rust). `cryptography` (50.0.0) also supports Ed25519 but `pynacl` is simpler for raw sign/verify and is the de-facto standard for EdDSA in Python. Private key = 32-byte seed; public key = 32 bytes; signature = 64 bytes. Store encrypted-at-rest in Postgres via `pgcrypto` symmetric `pgp_sym_encrypt` (key from operator secrets) or app-layer AES-GCM with `cryptography`. (Confidence: 0.90)
|
||||
|
||||
5. **The issuer does NOT need a DID.** VC-DM 2.0 §4.4 (Identifiers) and §4.7 (Issuer) explicitly allow the `issuer` value to be **any URL** — including a plain HTTPS URL like `https://praxis.example/issuers/v0.3`. DIDs are optional ("DIDs are not necessary for verifiable credentials to be useful"). **Simplest W3C-compliant issuer identifier: a HTTPS URL + a `verificationMethod` URL that dereferences to a Multikey public-key document served by the platform itself.** `did:key` is viable but overkill for a single platform-issued issuer and has a known limitation: no key rotation (DID is derived from the key — changing the key changes the DID). `did:web` adds HTTPS-resolution complexity with no benefit over a bare URL for one issuer. **Recommendation: bare HTTPS URL issuer ID + self-hosted Multikey verification method.** (Confidence: 0.85)
|
||||
|
||||
6. **Verification endpoint (D-043): return `{valid, status, issuer, credential}`.** A third-party verifier validates the signature by (a) canonicalizing the credential minus `proof` via JCS (RFC 8785), (b) SHA-256 hashing the canonical doc + proof config, (c) Ed25519-verifying the `proofValue` against the public key fetched from the `verificationMethod` URL. No shared secret — the public key is published at a public URL. Minimum response shape below. (Confidence: 0.90)
|
||||
|
||||
7. **Credential payload for "Mastery of Customer Service":** `credentialSubject` must assert `skill`, `level` ("mastery"), `path` ("customer-service"), `rubricScore` (mean), `scenariosPassed` (the N=3 distinct scenario IDs from D-032), `evidence` (mastery-gate audit per REQ-NFR-MAST-02), and `completedWeeks` (6, per PRD §6.4 path structure). `validFrom` = issuance; `validUntil` = optional (mastery does not expire, but a 3-year re-validation window is prudent). PRD §6.4 guidance = path-as-job, 6-week structure (D-037); the VC is **path-level, not week-level** (D-048). (Confidence: 0.80)
|
||||
|
||||
8. **Key rotation (D-042 strategy validated):** Rotate by generating a new Ed25519 keypair, marking the old key as `superseded` (NOT revoked) in the `issuer_keys` table, and serving the old public key indefinitely at its original `verificationMethod` URL. Old VCs still verify against the archived public key; new VCs reference the new key. `did:key` cannot do this (key IS the DID) — another reason bare-URL issuer ID is superior for this use case. (Confidence: 0.90)

## VC Data Model 2.0 Status
|
||||
|
||||
**Sources:** https://www.w3.org/TR/vc-data-model-2.0/ (fetched 2026-08-03), https://w3c.github.io/vc-data-model/ (editor's draft, v2.1 in progress).
|
||||
|
||||
### Finding: W3C Recommendation since 15 May 2025
|
||||
|
||||
The Verifiable Credentials Data Model v2.0 was published as a **W3C Recommendation on 15 May 2025** ([source](https://www.w3.org/TR/2025/REC-vc-data-model-2.0-20250515/)). This is the highest maturity level in the W3C process — equivalent to a ratified standard. The W3C explicitly "recommends the wide deployment of this specification as a standard for the Web." An editor's draft for v2.1 exists but v2.0 is the current normative reference. D-033's choice of "W3C VC Data Model 2.0" is therefore targeting a stable Recommendation, not a moving draft.
|
||||
|
||||
### What changed from 1.1
|
||||
|
||||
VC-DM 1.1 was a W3C Recommendation (3 Mar 2022). The 2.0 changes material to Praxis:
|
||||
|
||||
| Concern | VC-DM 1.1 | VC-DM 2.0 |
|
||||
|---|---|---|
|
||||
| Validity period | `issuanceDate` + `expirationDate` | `validFrom` + `validUntil` (§4.9) |
|
||||
| Required `@context` first item | `https://www.w3.org/2018/credentials/v1` | `https://www.w3.org/ns/credentials/v2` (§4.3) |
|
||||
| Media types | not registered | `application/vc`, `application/vp` registered at IANA (§6.2) |
|
||||
| Conforming document | JSON or JSON-LD | **compacted JSON-LD document** (§1.3) — JSON-LD processing is expected but "type-specific processing" (§6.3) permits pure-JSON verification when contexts are pinned |
|
||||
| Securing mechanisms | `proof` embedded (LD-Proofs) | Data Integrity 1.0 (embedded `proof`) **or** JOSE/COSE (enveloping) — both are companion specs ([VC-DATA-INTEGRITY](https://w3c.github.io/vc-data-integrity/), [VC-JOSE-COSE](https://w3c.github.io/vc-jose-cose/)) |
|
||||
| Status | `credentialStatus` (open) | `credentialStatus` + `status` (§4.10) — Bitstring Status List is the normative companion |
|
||||
| Evidence | `evidence` (open) | `evidence` (§5.6) — same, now typed |
|
||||
|
||||
**Implication for Praxis:** Use `validFrom`/`validUntil` (not the 1.1 names), pin `@context` to `credentials/v2`, and secure via **Data Integrity `eddsa-jcs-2022`** (embedded `proof`) — not JOSE/COSE. JCS canonicalization (RFC 8785) is pure-JSON and avoids RDF Dataset Canonicalization, which is the single biggest implementation complexity in the VC 2.0 stack.
|
||||
|
||||
### Python ecosystem readiness
|
||||
|
||||
The Python VC ecosystem is **not** "batteries-included." There is no `pip install python-vc` that issues and verifies W3C VC 2.0 credentials end-to-end. The components exist but must be assembled:
|
||||
|
||||
| Component | pip package | Status | Notes |
|
||||
|---|---|---|---|
|
||||
| Ed25519 sign/verify | `pynacl` 1.6.2 | ✅ production | Maintained by Python Cryptographic Authority; libsodium 1.0.20; Apache-2.0 |
|
||||
| Ed25519 (alt) | `cryptography` 50.0.0 | ✅ production | Also supports Ed25519; heavier; OpenSSL-backed |
|
||||
| JSON Canonicalization (JCS, RFC 8785) | `canonicaljson` 2.0.0 / `jcs` 0.2.1 | ⚠️ minimal | `canonicaljson` is from Ankidro (Anki ecosystem); `jcs` is a thin wrapper. Both implement RFC 8785. ~50 LOC to hand-roll if needed. |
|
||||
| Base58-btc (Multibase) | `base58` 2.1.1 | ✅ stable | Base58 codec only; Multibase prefix (`z`) is a literal `z` prepended |
|
||||
| JSON-LD processor | `pyld` 3.1.0 | ✅ stable | **Only needed for `eddsa-rdfc-2022` or JSON-LD expansion. NOT needed for `eddsa-jcs-2022`.** |
|
||||
| RDF Dataset Canonicalization | `rdf-canonicalize` | ⚠️ sparse | Required only for `eddsa-rdfc-2022`. Avoid by choosing JCS. |
|
||||
| did:key resolution | none standard | ⚠️ | did:key is generative — ~30 LOC to expand a Multikey from the DID string |
|
||||
|
||||
**No `py-vc`, `vc-js`, or `did-jwt` on PyPI** — these are JavaScript libraries (`@digitalbazaar/py-vc` is a JS package despite the name; `did-jwt` is Transmute's JS lib). The Python path is **assemble-from-primitives**.
|
||||
|
||||
**Confidence: 0.98** (status); **0.80** (Python readiness assessment — based on PyPI registry inspection 2026-08-03; the absence of a unified lib is well-known in the VC community).
|
||||
|
||||
---
|
||||
|
||||
## Python Library Recommendation
|
||||
|
||||
**Recommendation: assemble the VC issuer/verifier from 4 pip packages + ~200 LOC of glue.**
|
||||
|
||||
### pip-installable dependencies (add to `pyproject.toml` `[project.optional-dependencies] vc`)
|
||||
|
||||
```toml
|
||||
[project.optional-dependencies]
|
||||
vc = [
|
||||
"pynacl>=1.5", # Ed25519 sign/verify (libsodium)
|
||||
"canonicaljson>=2.0", # RFC 8785 JSON Canonicalization Scheme (JCS)
|
||||
"base58>=2.1", # base58-btc encoding for Multibase proofValue
|
||||
"pydantic>=2.7", # already a dep — use for VC schema validation
|
||||
]
|
||||
```
|
||||
|
||||
### Why this stack
|
||||
|
||||
- **`pynacl` over `cryptography` for Ed25519:** PyNaCl's `nacl.signing.SigningKey` / `VerifyKey` API is purpose-built for EdDSA and returns raw 64-byte signatures — exactly what `eddsa-jcs-2022` requires. `cryptography` works but its Ed25519 API is more verbose and OpenSSL-dependent. PyNaCl bundles libsodium (no system dep).
|
||||
- **`canonicaljson` over `jcs`:** `canonicaljson` (Anki ecosystem, 2.0.0) is more actively maintained and implements RFC 8785 fully. `jcs` 0.2.1 is thinner but less proven.
|
||||
- **No `pyld` / no `rdf-canonicalize`:** By choosing the **`eddsa-jcs-2022`** cryptosuite (not `eddsa-rdfc-2022`), we avoid the entire JSON-LD → RDF → canonicalization pipeline. JCS operates on JSON directly. This is the single largest complexity reduction available. The VC-DM 2.0 "type-specific processing" clause (§6.3) explicitly permits this: "implementations MAY choose to not perform JSON-LD expansion... when using type-specific processing rules."

### Code shape (illustrative — NOT committed code, per research-only constraint)
|
||||
|
||||
```python
|
||||
# Issue
|
||||
sk = nacl.signing.SigningKey.generate() # 32-byte seed
|
||||
pk_bytes = bytes(sk.verify_key) # 32 bytes
|
||||
proof_config = {"type": "DataIntegrityProof",
|
||||
"cryptosuite": "eddsa-jcs-2022",
|
||||
"created": "2026-08-03T12:00:00Z",
|
||||
"verificationMethod": "https://praxis.example/keys/v0.3#key-1",
|
||||
"proofPurpose": "assertionMethod"}
|
||||
canonical_proof = canonicaljson.canonicalize(proof_config)
|
||||
canonical_doc = canonicaljson.canonicalize(credential_without_proof)
|
||||
hash_data = hashlib.sha256(canonical_proof).digest() + hashlib.sha256(canonical_doc).digest()
|
||||
proof_bytes = sk.sign(hash_data).signature # 64 bytes
|
||||
proof_config["proofValue"] = "z" + base58.b58encode(proof_bytes).decode()
|
||||
credential_with_proof = {**credential_without_proof, "proof": proof_config}
|
||||
|
||||
# Verify
|
||||
verify_key = nacl.signing.VerifyKey(pk_bytes) # fetched from verificationMethod URL
|
||||
proof_value = base58.b58decode(proof_config["proofValue"][1:]) # strip 'z' Multibase prefix
|
||||
verify_key.verify(hash_data, proof_value) # raises BadSignatureError if invalid
|
||||
```
|
||||
|
||||
**Confidence: 0.80** — the assembly pattern is well-documented in the [eddsa-jcs-2022 spec](https://w3c.github.io/vc-di-eddsa/) (fetched 2026-08-03); the risk is in the ~200 LOC of glue (proof config ordering, context pinning) which is standard but unverified here.

## Status List Revocation
|
||||
|
||||
**Sources:** https://www.w3.org/TR/vc-bitstring-status-list/ (fetched 2026-08-03) — **W3C Recommendation 15 May 2025**, titled "Bitstring Status List v1.0".
|
||||
|
||||
### How it works
|
||||
|
||||
The issuer maintains a single bitstring (minimum 131,072 bits = 16 KB uncompressed) where each bit corresponds to one issued credential's status. The bitstring is GZIP-compressed, Multibase-encoded (base64url, no padding), and published as the `encodedList` field inside a **`BitstringStatusListCredential`** — itself a verifiable credential signed by the issuer. Each issued credential carries a `credentialStatus` entry:
|
||||
|
||||
```json
|
||||
"credentialStatus": {
|
||||
"type": "BitstringStatusListEntry",
|
||||
"statusPurpose": "revocation",
|
||||
"statusListIndex": "94567",
|
||||
"statusListCredential": "https://praxis.example/status/v0.3"
|
||||
}
|
||||
```
|
||||
|
||||
A verifier (a) dereferences `statusListCredential`, (b) verifies that VC's own proof, (c) GZIP-decompresses + Multibase-decodes `encodedList`, (d) reads the bit at `statusListIndex`. Bit = 1 means revoked; 0 means active. `statusPurpose` can be `revocation` (irreversible), `suspension` (reversible), `refresh`, or `message`.
|
||||
|
||||
### Implementable without a third-party service — YES
|
||||
|
||||
The status list is **just another VC published at a static URL by the issuer**. No registry, no ledger, no OCSP responder. The issuer regenerates + republishes the `BitstringStatusListCredential` whenever a credential is revoked. CDN-cacheable by design (the spec §6.4 explicitly recommends CDN distribution for privacy).
|
||||
|
||||
### Minimum viable revocation setup for a single issuer (Praxis)
|
||||
|
||||
1. **One status list URL:** `https://praxis.example/status/v0.3` — serves the `BitstringStatusListCredential` (signed by the same Ed25519 issuer key).
|
||||
2. **One bit per issued credential:** `statusPurpose: "revocation"`, `statusSize: 1` (default).
|
||||
3. **In-process generation:** maintain a 131,072-bit bytearray in Postgres (`status_lists` table: `id, status_purpose, encoded_list, updated_at`). On revocation, flip the bit, GZIP-compress, Multibase-encode, re-sign the list VC, persist, serve.
|
||||
4. **Random index assignment:** spec §2.1 recommends random `statusListIndex` allocation to prevent inference of issuance order or population size.
|
||||
5. **For v0.3 scale (likely <1000 credentials):** a single list with 131,072 slots is wildly over-provisioned — compressed size stays a few hundred bytes. No need for multiple lists until >100k credentials.
|
||||
|
||||
**Confidence: 0.95** — the spec is a Recommendation and the algorithm (§3.1 Generate, §3.2 Validate, §3.3 Bitstring Generation, §3.4 Bitstring Expansion) is fully specified and implementable in ~100 LOC of Python (`gzip`, `base64`, `bitarray`/`bytearray`).

||||
## Issuer Identifier Strategy
|
||||
|
||||
**Sources:** VC-DM 2.0 §4.4 (Identifiers), §4.7 (Issuer); [did:key Method v0.9](https://w3c-ccg.github.io/did-key-spec/) (fetched 2026-08-03).
|
||||
|
||||
### Does platform-issued require a DID? — NO
|
||||
|
||||
VC-DM 2.0 §4.4: "The `id` property is OPTIONAL... Example `id` values include UUIDs... HTTP URLs (`https://id.example/things#123`), and DIDs." §4.7: the `issuer` value "MUST be either a URL or an object containing an `id` property whose value is a URL." DIDs are *optional* — the spec explicitly states "DIDs are not necessary for verifiable credentials to be useful."
|
||||
|
||||
The Data Integrity `verificationMethod` (which holds the public key) is also just a URL that dereferences to a Multikey document. No DID resolution is required if the URL is self-hosted.
|
||||
|
||||
### Three options compared
|
||||
|
||||
| Option | Example | Key rotation | Complexity | W3C-compliant? |
|
||||
|---|---|---|---|---|
|
||||
| **Bare HTTPS URL** | `https://praxis.example/issuers/v0.3` | ✅ Archive old key at old URL; new key at new URL | Lowest — serve a static JSON file | ✅ Yes (§4.4, §4.7) |
|
||||
| `did:web` | `did:web:praxis.example:issuers:v0.3` | ✅ Update DID document at `/.well-known/did.json` | Medium — DID document format, well-known path | ✅ Yes |
|
||||
| `did:key` | `did:key:z6Mk...` | ❌ **No rotation** — DID is derived from the key; changing the key changes the DID | Low to implement, but breaks D-042 rotation | ✅ Yes, but unsuitable for long-lived issuer |
|
||||
|
||||
### Recommendation: Bare HTTPS URL issuer ID
|
||||
|
||||
```json
|
||||
"issuer": "https://praxis.example/issuers/v0.3",
|
||||
"proof": {
|
||||
"verificationMethod": "https://praxis.example/keys/v0.3#key-1",
|
||||
...
|
||||
}
|
||||
```
|
||||
|
||||
Where `GET https://praxis.example/keys/v0.3` returns a "controlled identifier document" (per the [CID spec](https://w3c.github.io/controller-document/)) containing:
|
||||
|
||||
```json
|
||||
{
|
||||
"@context": ["https://www.w3.org/ns/credentials/v2"],
|
||||
"id": "https://praxis.example/keys/v0.3",
|
||||
"verificationMethod": [{
|
||||
"id": "https://praxis.example/keys/v0.3#key-1",
|
||||
"type": "Multikey",
|
||||
"controller": "https://praxis.example/issuers/v0.3",
|
||||
"publicKeyMultibase": "z6Mk...<base58-btc(0xed01 + 32-byte pubkey)>"
|
||||
}]
|
||||
}
|
||||
```
|
||||
|
||||
This is the **simplest viable W3C-compliant issuer identifier**. It supports key rotation (D-042 strategy: archive old `verificationMethod` documents, serve new ones), requires no DID resolution infrastructure, and is verifiable by any Data Integrity compliant verifier.
|
||||
|
||||
`did:key` is rejected despite being simplest to generate because its documented limitation (spec §Security: "Key Rotation Not Supported," "Long Term Usage is Discouraged") directly conflicts with D-042's rotation requirement. `did:web` adds the `did.json` well-known-path convention and DID-document schema for zero benefit over a bare URL when there's exactly one issuer.
|
||||
|
||||
**Confidence: 0.85** — the VC-DM 2.0 text is unambiguous that URLs are valid issuer IDs; the bare-URL + Multikey pattern is used in the spec's own Example 3 (`"issuer": "https://university.example/issuers/565049"`).
|
||||
|
||||

|
||||
|
||||
## Verification Endpoint Design
|
||||
|
||||
**Sources:** D-043 (decided: public unauthenticated `GET /vc/verify/<id>`), VC-DM 2.0 §7.1 (Verification), §7.2 (Problem Details), Data Integrity eddsa-jcs-2022 Verify Proof algorithm.
|
||||
|
||||
### How a third-party verifier validates the signature (no shared secret)
|
||||
|
||||
1. **Fetch the credential** — `GET /vc/verify/<id>` returns the stored VC (or the caller already holds the VC and just wants status; see response shape below).
|
||||
2. **Extract `proof`** — remove `proof` from the secured document to get `unsecuredDocument`; copy `proof` minus `proofValue` to get `proofOptions`.
|
||||
3. **Canonicalize** — apply JCS (RFC 8785) to `unsecuredDocument` and to `proofOptions` → `canonicalDocument`, `canonicalProofConfig`.
|
||||
4. **Hash** — `hashData = SHA-256(canonicalProofConfig) || SHA-256(canonicalDocument)` (64 bytes total).
|
||||
5. **Fetch public key** — dereference `proof.verificationMethod` → controlled identifier document → extract `publicKeyMultibase` → Multibase-decode (strip `z`, base58-decode) → strip 2-byte `0xed01` Multikey prefix → 32-byte Ed25519 public key.
|
||||
6. **Verify** — Ed25519 `Verify(pk, hashData, proofValue)` where `proofValue` is Multibase-decoded `proof.proofValue`. Raises on failure.
|
||||
7. **Check status** — dereference `credentialStatus.statusListCredential`, verify its proof, expand bitstring, read bit at `statusListIndex`. 0 = active, 1 = revoked.
|
||||
8. **Check validity window** — `validFrom` ≤ now ≤ `validUntil` (if `validUntil` present).
|
||||
|
||||
No shared secret, no API key, no account. The public key is published at a public URL; everything else is math.
|
||||
|
||||
### Minimum response shape for `GET /vc/verify/<id>`
|
||||
|
||||
Per D-043: `{valid: bool, status: "active"|"revoked", issuer: "praxis-v0.3", mastery: {...}}`. Refined with spec-aware fields:
|
||||
|
||||
```json
|
||||
{
|
||||
"valid": true,
|
||||
"status": "active",
|
||||
"issuer": {
|
||||
"id": "https://praxis.example/issuers/v0.3",
|
||||
"name": "Praxis"
|
||||
},
|
||||
"credential": {
|
||||
"id": "https://praxis.example/vc/01J...',
|
||||
"type": ["VerifiableCredential", "MasteryCredential"],
|
||||
"validFrom": "2026-08-03T12:00:00Z",
|
||||
"validUntil": "2029-08-03T12:00:00Z"
|
||||
},
|
||||
"mastery": {
|
||||
"skill": "customer-service",
|
||||
"level": "mastery",
|
||||
"path": "customer-service",
|
||||
"rubricScore": 4.1,
|
||||
"scenariosPassed": ["cs_refund_ca_v01", "cs_escalation_v02", "cs_billing_v01"],
|
||||
"completedWeeks": 6
|
||||
},
|
||||
"verifiedAt": "2026-08-03T14:30:00Z"
|
||||
}
|
||||
```
|
||||
|
||||
**Privacy (D-043 constraint):** No learner PII beyond what the credential itself asserts. The `credentialSubject.id` (if any) is NOT echoed in the verification response — only the mastery claims. The full signed VC is retrievable via a separate `GET /vc/<id>` endpoint that the holder can choose to share, or the holder presents the VC directly to the verifier and the verifier calls `/vc/verify/<id>` only for status.
|
||||
|
||||
**Error responses** (per VC-DM 2.0 §7.2, RFC 9457 Problem Details):
|
||||
|
||||
| HTTP | `type` suffix | Meaning |
|
||||
|---|---|---|
|
||||
| 404 | `not-found` | No credential with that ID |
|
||||
| 200 | — | `valid: true` + status |
|
||||
| 200 | — | `valid: false`, `status: "revoked"` |
|
||||
| 410 | — | `valid: false`, `status: "revoked"` (alternative — 410 Gone signals the credential is "gone" but still returns body) |
|
||||
|
||||
**Recommendation:** always return 200 with `valid: false` for revoked/invalid-but-existing credentials (simpler client logic); 404 only for non-existent IDs.
|
||||
|
||||
**Confidence: 0.90** — D-043 fixed the endpoint; the response shape is derived from spec verification semantics + the privacy constraint.
|
||||

## Credential Payload Schema
|
||||
|
||||
**Sources:** PRD §6.4 (path-as-job, 6-week structure — referenced via D-037, REQ-PATH-02), D-032 (mastery gate: N=3 scenarios, rubric mean ≥ 3.5), D-048 (VC on week-final gate, path-level), D-039 (rubric YAML), REQ-NFR-MAST-02 (gate auditability), VC-DM 2.0 §4.2, §5.6 (Evidence).
|
||||
|
||||
### Claims for "Mastery of Customer Service"
|
||||
|
||||
To be credible to an employer, the VC must assert **what** was mastered, **how** it was assessed, and **who** says so — with enough evidence that the employer can audit the claim without contacting Praxis.
|
||||
|
||||
```json
|
||||
{

||||

|
||||
}
|
||||
```
|
||||
|
||||
### Claim rationale
|
||||
|
||||
| Claim | Why it's there | Source |
|
||||
|---|---|---|
|
||||
| `skill` | The competency domain — what the employer cares about | D-033, D-039 |
|
||||
| `level: "mastery"` | Distinguishes from "in-progress" or "completion" | D-032 (mastery gate) |
|
||||
| `path` | Which 6-week job-structured path (PRD §6.4) | D-037, REQ-PATH-02 |
|
||||
| `completedWeeks: 6` | Proves full path completion, not partial | D-048 (VC only on final gate) |
|
||||
| `rubricScore` + `rubricMax` + `rubricThreshold` | Quantified competency — employer can judge stringency | D-032 (≥3.5/5.0), D-039 (rubric) |
|
||||
| `scenariosPassed` (3 IDs) | **Varied-scenario evidence** — the load-bearing anti-gaming claim (D-032: N=3 distinct) | D-032, D-047 |
|
||||
| `evidence[].gateOpenedAt` | Auditability of the gate-open event | REQ-NFR-MAST-02 |
|
||||
| `credentialSubject.id` | Pseudonymous learner ID (urn:uuid) — NOT a real name. Employer contacts Praxis out-of-band to dereference if needed. | Privacy (D-043) |
|
||||
| `validUntil` (3 years) | Mastery doesn't "expire" but employers want a re-validation window. 3 years is a defensible default; Praxis can re-issue on re-assessment. | PRD §6.4 (no explicit expiry guidance — this is a recommendation) |
|
||||
| `credentialStatus` | Revocation path (compromised key, fraud detected) | D-033 (status list), REQ-NFR-VC-02 |
|
||||
|
||||
### What PRD §6.4 says
|
||||
|
||||
PRD §6.4 is not a file in this repo — it is referenced by D-037 and REQ-PATH-02 as the source for the **"path-as-job 6-week structure."** The operative guidance: a path is structured as a job (6 weeks), mastery-paced, with mastery gates between weeks. The VC is **path-level** (D-048: "VCs are path-level, not week-level"), issued only when the **final** week's gate opens. This research confirms the credential payload should assert `completedWeeks: 6` and the full path slug — not per-week credentials (D-048 rejected "VC per week" as "credential spam").
|
||||
|
||||
**Confidence: 0.80** — the claim set is grounded in D-032/037/039/048 + REQ-NFR-MAST-02; the `validUntil` 3-year window is a recommendation (PRD §6.4 is silent on expiry), hence the 0.80 not higher.
|
||||

|
||||
|
||||
## Key Rotation Strategy
|
||||
|
||||
**Sources:** D-042 (issuer key in secrets, generated on first init, archived-when-superseded), did:key spec §Security (no rotation), VC-DM 2.0 §9.2 (Key Management).
|
||||
|
||||
### The problem
|
||||
|
||||
Ed25519 keys should be rotated periodically (compromise hygiene) and on suspected exposure. But VCs are signed with a specific key; if the key changes, existing VCs must still verify.
|
||||
|
||||
### D-042 strategy (validated)
|
||||
|
||||
1. **`issuer_keys` table in Postgres** (operator-tier, per D-040):
|
||||
```
|
||||
issuer_keys(
|
||||
key_id UUID PRIMARY KEY,
|
||||
public_key BYTEA NOT NULL, -- 32 bytes
|
||||
encrypted_priv BYTEA NOT NULL, -- pgp_sym_encrypt or app-layer AES-GCM
|
||||
created_at TIMESTAMPTZ NOT NULL,
|
||||
superseded_at TIMESTAMPTZ, -- NULL = active
|
||||
status TEXT NOT NULL -- 'active' | 'superseded'
|
||||
)
|
||||
```
|
||||
2. **At first init:** generate Ed25519 keypair, encrypt private key with a root key from operator secrets (`PRAXIS_VC_ROOT_KEY`), insert as `status='active'`.
|
||||
3. **To rotate:**
|
||||
- Generate new keypair.
|
||||
- Insert new row `status='active'`.
|
||||
- Update old row: `status='superseded', superseded_at=now()`. **Do NOT delete.** The old public key remains in the table and is still served at its original `verificationMethod` URL.
|
||||
- New VCs reference the new `verificationMethod` URL (`...#key-2`); old VCs still reference `...#key-1`.
|
||||
4. **Verification of old VCs:** verifier fetches `https://praxis.example/keys/v0.3#key-1` → archived public key → Ed25519 verify succeeds. The old key is **archived, not revoked** — the signature still verifies.
|
||||
5. **Verification of new VCs:** verifier fetches `...#key-2` → current public key → verify succeeds.
|
||||
6. **Revocation of individual VCs** (distinct from key rotation): handled by the Bitstring Status List, not by key rotation. A key compromise would trigger (a) rotation + (b) bulk-revocation of all VCs signed by the compromised key via the status list.
|
||||
|
||||
### Why `did:key` is incompatible with this strategy
|
||||
|
||||
`did:key` derives the DID from the public key (`did:key:z6Mk...`). Changing the key produces a **different DID**. There is no way to "archive" the old DID — it's a new identity. This means either (a) all old VCs show an issuer DID that no longer "exists" in any meaningful sense (though the public key is still embedded in the DID string and verification still works), or (b) reissue all old VCs under the new DID. The bare-URL strategy avoids this entirely: the issuer URL stays stable (`https://praxis.example/issuers/v0.3`), only the `#key-N` fragment changes.
|
||||
|
||||
### Encrypted-at-rest in Postgres — two options
|
||||
|
||||
| Option | Mechanism | Pros | Cons |
|
||||
|---|---|---|---|
|
||||
| **`pgcrypto` `pgp_sym_encrypt`** | Postgres extension; `INSERT ... pgp_sym_encrypt($1, $2)` | DB-level; no app crypto | `pgcrypto` must be enabled; key passed in SQL (audit log risk) |
|
||||
| **App-layer AES-GCM (`cryptography`)** | `cryptography.hazmat.primitives.ciphertext.AEAD.AESGCM`; encrypt before INSERT | Key never touches DB; auditable in app | Adds `cryptography` dep (already likely present via transitive) |
|
||||
|
||||
**Recommendation: app-layer AES-GCM** — the root key (`PRAXIS_VC_ROOT_KEY`) stays in the FastAPI process (from `os.environ`), never in SQL. Store `nonce || ciphertext || tag` as a single `BYTEA`. This aligns with D-042's "encrypted at rest with a root key from secrets" and avoids `pgcrypto` extension dependencies in the LXC Docker Postgres (D-040).
|
||||
|
||||
**Confidence: 0.90** — the rotation-without-invalidation pattern is standard key-management practice and is explicitly what D-042 specifies; the did:key incompatibility is documented in the did:key spec itself.

## Risks & Unknowns
|
||||
|
||||
1. **`eddsa-jcs-2022` interop:** While the spec is clear, the *ecosystem* of verifiers is more saturated with `eddsa-rdfc-2022` (RDF canonicalization) and JOSE/SD-JWT. An employer using a generic VC verifier wallet may not have a JCS cryptosuite implementation. **Mitigation:** also publish the VC in `application/vc` (Data Integrity) — most modern verifiers support Data Integrity; JCS is a recognized cryptosuite. If employer-interop friction emerges, consider adding an SD-JWT (JOSE) representation in v0.4. **Confidence: 0.55** (ecosystem adoption is hard to measure).
|
||||
|
||||
2. **JCS implementation correctness:** `canonicaljson` is used by Anki but is not a W3C-referenced normative implementation. RFC 8785 has edge cases (number serialization, key ordering). **Mitigation:** pin `canonicaljson>=2.0.0`; add round-trip test vectors from RFC 8785 to the test suite; verify against the [eddsa-jcs-2022 test suite](https://w3c.github.io/vc-di-eddsa-test-suite/) if one exists at implementation time.
|
||||
|
||||
3. **Status list herd privacy at v0.3 scale:** The 131,072-bit minimum gives herd privacy only if the issued population is large. At v0.3 pilot scale (<100 learners), a verifier can infer that the issuer has few credentials. The spec §6.1 acknowledges this. **Mitigation:** acceptable for pilot — the privacy loss is the *issuer's* (Praxis), not the learner's, and Praxis is not a privacy adversary. Revisit at scale.
|
||||
|
||||
4. **`validUntil` 3-year window is a recommendation, not PRD-grounded.** PRD §6.4 does not specify expiry. If employers reject expiring mastery credentials ("mastery doesn't expire"), set `validUntil` to null and rely on status-list revocation for fraud. **Decision needed at PLAN stage.**
|
||||
|
||||
5. **Learner PII in `credentialSubject.id`:** Using a pseudonymous `urn:uuid` learner ID means the VC cannot be self-sovereignly held by the learner in a universal wallet (the ID is Praxis-internal). For v0.3 (platform-issued, platform-verified) this is fine. For v0.9 (learner-held portable credentials), the learner will need a DID or the VC will need to support holder-binding differently. **Out of v0.3 scope** (D-033 defers third-party/holder-issued to v0.9).
|
||||
|
||||
6. **Public key endpoint availability:** If `https://praxis.example/keys/v0.3` is down, all verification fails. The Multikey document is tiny (~300 bytes) and should be served from the same FastAPI app + cached at a CDN. **Mitigation:** static file; long `Cache-Control` max-age.

# Praxis — Research Findings (v0.3 Mastery Scoring + Competency Rubrics)
|
||||
|
||||
> **Phase:** v0.3 research (mastery scoring + competency rubrics + verifiable credentials + cohort dashboard)
|
||||
> **Branch:** `phase/00-pre-execution`
|
||||
> **Status:** research complete
|
||||
> **Date:** 2026-08-03
|
||||
> **Method:** Four parallel research agents (rubric/mastery models, W3C VC stack, multi-tenant auth + Postgres-in-LXC, anonymization + IRT + scenario library). Full agent outputs preserved in `docs/mastery-scoring-research.md`, `.ciagent/RESEARCH-vc.md`, `docs/RESEARCH-operator-postgres-auth.md`, `.ciagent/RESEARCH-v0.3-anonymization-irt-scenarios.md`. This section is the consolidated summary for PLAN; the detailed files are retained as appendices.
|
||||
|
||||
## v0.3 Research Summary (Executive 1-Pager)
|
||||
|
||||
1. **Rubric model = Dreyfus 5-stage + Miller "Does" tier + EPA entrustment + Bloom mastery-learning gate.** (Confidence: 0.82) Bloom's *taxonomy* alone is a weak fit for "do the job" assessment; Dreyfus anchors the 5 levels behaviorally, Miller's pyramid ensures anchors describe *doing* (not *knowing*), EPA entrustment language makes level 5 = "entrustable + coaches peers." Bloom mastery learning governs the gate philosophy (iterate until mastery, not rank).
|
||||
|
||||
2. **5-level rubric anchoring is well-grounded for Customer Service.** (0.78) Four criteria: empathy, resolution-concreteness, de-escalation, professionalism. Level 3 = "competent entry-level hire, unsupervised." Level 5 = "entrustable, coaches peers." Concrete anchor table in appendix.
|
||||
|
||||
3. **N=3 mastery gate is defensible ONLY as formative/path-completion, NOT high-stakes credentialing.** (0.62) Generalizability theory suggests G≈0.5–0.6 for N=3 — adequate for "advance to next week" but thin for a credential employers trust. **Recommendation: label v0.3 VC as *formative*, reserve N=5–6 + blueprint coverage for a future high-stakes tier (v0.9 credentialing milestone).** Keep the remediation loop (Bloom mastery learning lives there).
|
||||
|
||||
4. **Mastery Score = hybrid weighted-mean + conjunctive floor.** (0.72) Weighted mean of criterion scores (D-039 weights), conjunctive floor: every criterion ≥2 AND scenario mean ≥3.0 to pass that scenario. Path-level mastery gate: ≥3 distinct scenarios passed AND additive MasteryScore ≥3.5 over passing scenarios only (D-032 validated, but see §3: label formative).
|
||||
|
||||
5. **Deterministic rubric scoring: LLM-extracts-evidence, rules-score-evidence (D-038 validated).** (0.80) LLM (deepseek-v4-flash:cloud, temp=0, JSON-schema-validated output) extracts verbatim quotes + signal tags per criterion from session turns; a deterministic YAML rule engine maps signals → 1-5 levels. **Critical: validate extracted quotes fuzzy-match the transcript to block LLM hallucination.** This is the strongest-evidence finding.
|
||||
|
||||
6. **CS weights for refund/complaint: empathy 0.35, resolution 0.30, de-escalation 0.20, professionalism 0.15.** (0.70) Professionalism is a *floor* (conjunctive ≥2), not a weight driver. De-escalation up-weights to ~0.40 if the escalate branch triggers (D-009). **D-039 amendment: weights should be per-scenario-archetype, not one global CS set** — allow `rubrics/customer_service_<archetype>.yaml` or a weights override in the scenario file.
|
||||
|
||||
7. **W3C VC Data Model 2.0 is a W3C Recommendation (15 May 2025) — D-033 targets a stable standard.** (0.85) No batteries-included Python VC library exists; assemble `pynacl` + `canonicaljson` + `base58` + ~200 LOC using the `eddsa-jcs-2022` cryptosuite (avoids RDF canonicalization complexity). Bitstring Status List v1.0 is also a W3C Recommendation — fully self-hostable, no third-party service.
|
||||
|
||||
8. **Issuer ID = bare HTTPS URL (`https://praxis.example/issuers/v0.3`) + self-hosted Multikey public key.** (0.80) `did:key` rejected because it breaks D-042 key rotation (key is baked into the DID). Bare URL + Multikey is W3C-compliant and allows key rotation by archiving the old public key at its original URL (status `superseded`, not revoked — old VCs still verify).
|
||||
|
||||
9. **Verification endpoint returns `{valid, status, issuer, credential, mastery, verifiedAt}`.** (0.80) Verifier fetches the public key from the `verificationMethod` URL, validates the Ed25519 signature, checks status list. No shared secret, no account. Credential payload: `scenariosPassed` (anti-gaming per D-032), `rubricScore`, `completedWeeks: 6` (PRD §6.4), `evidence` (REQ-NFR-MAST-02). **Open: 3-year `validUntil` is a recommendation (PRD §6.4 silent on expiry) — flag for PLAN.**
|
||||
|
||||
10. **Operator Postgres = `postgres:16-slim` as a second docker-compose service on an explicit named bridge network, no published port.** (0.90) `pgdata` named volume, `pg_isready` healthcheck, `depends_on: service_healthy`, init scripts at `/docker-entrypoint-initdb.d/`. **asyncpg `create_pool(min_size=2, max_size=10)` on `app.state` via lifespan; do not share a session with aiosqlite.** New pip deps: `asyncpg>=0.29`, `argon2-cffi>=23.1`, `slowapi>=0.1`.
|
||||
|
||||
11. **Operator auth = Starlette `SessionMiddleware` (itsdangerous-signed, httpOnly+Secure+SameSite=Strict, 8h) + argon2-cffi + slowapi 5/min.** (0.90 stack / 0.70 rate-limit for single-instance) One `current_operator` `Depends` + router-level `dependencies=[...]` under `/op`. Migrate to RBAC only when a 2nd role appears.
|
||||
|
||||
12. **Postgres schema: `operators`, `issued_credentials`, `mastery_gate_events`, `cohort_aggregates` (k-anon via write-time suppression, weekly partitions, 7-day window on read).** (0.80) `gen_random_uuid()` built into PG16 (no extension). Migration: staging-CT first, add service + net + volumes, build new image, then `up -d postgres` → `up -d praxis` recreate (~5–15s downtime, SQLite volume untouched → learner path never regresses). Mirror the existing `db/migrate.py` runner for Postgres (separate migration directory).
|
||||
|
||||
13. **Backup: daily `pg_dump -Fc` to a `pgbackups` named volume, `%u` rolling 7-file retention.** (0.85) Separate from the SQLite volume backup. Drill with `pg_restore --clean --if-exists`.
|
||||
|
||||
14. **k=10 + 7-day trailing window is the right floor for v0.3 (<100 learners).** (0.85) Defer l-diversity/t-closeness until a sensitive attribute enters the cohort schema; defer differential privacy until N>1000. SQL suppression via `COUNT(DISTINCT learner_id) >= 10` with `cell_suppressed` sentinel; limit to pre-defined 2-D views to block differencing attacks.
|
||||
|
||||
15. **IRT 1PL/Rasch: Gaussian-approximation Bayesian θ update (θ₀=0, σ²=1).** (0.80) Target P=0.5 for mastery-gate scenarios, P≈0.7 for practice scenarios (per-scenario `irt_target_p` field). θ reliable after ~5–10 sessions. Ship 1PL (2PL needs ~200 responses/item — post-pilot). **D-046 validated: θ persists in learner-local SQLite (`learner_ability` table: learner_id, path, theta, updated_at).**
|
||||
|
||||
16. **Scenario library: `index.yaml` as slim manifest (metadata only, ~50 lines/scenario).** (0.85) Semver per scenario (MAJOR = rubric_criteria/branch changes invalidate gate evidence). AI variations via `_pending/` dir + mandatory expert review + `generated_from` backref + `intent_hash` for structural-drift detection. Rubric mapping as list of `{criterion_id, weight, evidence_required}` objects. `MIN_COVERAGE = 2` scenarios per rubric criterion enforced in CI.

## v0.3 Detailed Findings
|
||||
|
||||
### A. Rubric + Mastery Models
|
||||
|
||||
**Rubric model selection (0.82):** Dreyfus 5-stage anchors + Miller's "Does" tier + EPA entrustment language for level 5 + Bloom mastery learning for the gate philosophy. Bloom's *taxonomy* alone is a weak fit for performance assessment.
|
||||
|
||||
**5-level anchor example (Customer Service — refund/complaint archetype):**
|
||||
|
||||
| Criterion | Level 1 (Fail) | Level 3 (Competent) | Level 5 (Mastery/Entrustable) |
|
||||
|-----------|----------------|---------------------|-------------------------------|
|
||||
| Empathy | Ignores/invalidates emotion | Acknowledges emotion before resolution | Names emotion preemptively, validates without surrendering policy |
|
||||
| Resolution | No concrete offer | Offers refund OR replacement | Offers choice, confirms next steps, anticipates follow-up |
|
||||
| De-escalation | Matches/escalates hostility | Stays calm, doesn't inflame | Re-frames hostility into problem-solving, recovers the relationship |
|
||||
| Professionalism | Profane/impersonates real co | Polite, in-role, disclaimer given | Models conduct, names policy without hiding behind it |
|
||||
|
||||
**N=3 defensibility (0.62):** Defensible only as *formative/path-completion*; not defensible as high-stakes credential (G-theory suggests G≈0.5–0.6). **Recommendation: label v0.3 VC as formative; reserve N=5–6 with blueprint coverage for a future high-stakes tier.**
|
||||
|
||||
**Mastery Score computation (0.72):** Hybrid — weighted mean of criterion scores + conjunctive floor (every criterion ≥2, scenario mean ≥3.0 to pass). Path-level gate: ≥3 distinct passed scenarios AND additive MasteryScore ≥3.5 over passing scenarios only.
|
||||
|
||||
**Deterministic scoring (0.80):** LLM (deepseek-v4-flash:cloud, temp=0) extracts verbatim quotes + signal tags (JSON-schema-validated) from session turns; deterministic YAML rule engine maps signals → 1-5 levels. **Validate quotes fuzzy-match the transcript to block hallucination.** No LLM in the numeric scoring step (preserves REQ-NFR-MAST-01).
|
||||
|
||||
**CS weights (0.70):** empathy 0.35, resolution 0.30, de-escalation 0.20, professionalism 0.15. Professionalism = floor (≥2), not weight driver. De-escalation up-weights to ~0.40 if escalate branch triggers. **D-039 amendment: per-archetype weights, not one global CS set.**
|
||||
|
||||
### B. Verifiable Credentials Stack
|
||||
|
||||
**VC Data Model 2.0 (0.85):** W3C Recommendation (15 May 2025). D-033 targets a stable standard.
|
||||
|
||||
**Python library (0.80):** No batteries-included VC lib. Assemble: `pynacl` (Ed25519) + `canonicaljson` (JCS canonicalization) + `base58` (Multikey encoding) + ~200 LOC using the `eddsa-jcs-2022` cryptosuite. Avoids RDF canonicalization complexity.
|
||||
|
||||
**Status List revocation (0.80):** Bitstring Status List v1.0 (W3C Recommendation). Fully self-hostable — no third-party service. Minimum viable: one bitstring per status list, indexed by credential sequence.
|
||||
|
||||
**Issuer ID (0.80):** Bare HTTPS URL (`https://praxis.example/issuers/v0.3`) + self-hosted Multikey public key. `did:key` rejected — key baked into DID breaks rotation (D-042).
|
||||
|
||||
**Verification endpoint (0.80):** `GET /vc/verify/<id>` → `{valid, status, issuer, credential, mastery, verifiedAt}`. Verifier fetches public key from `verificationMethod` URL, validates Ed25519 signature, checks status list. No account, no shared secret.
|
||||
|
||||
**Credential payload:** `scenariosPassed` (D-032 anti-gaming), `rubricScore`, `completedWeeks: 6` (PRD §6.4), `evidence` (REQ-NFR-MAST-02). **Open: 3-year `validUntil` is a recommendation (PRD §6.4 silent) — flag for PLAN.**
|
||||
|
||||
**Key rotation (D-042 validated, 0.80):** Archive old public key at its original URL (status `superseded`, not revoked). New key signs new VCs. Old VCs still verify against archived public key.
|
||||
|
||||
### C. Multi-Tenant Auth + Postgres-in-LXC
|
||||
|
||||
**Docker-compose shape (0.90):** `postgres:16-slim`, explicit named bridge network (not `host`), no published port, `pgdata` named volume, `pg_isready` healthcheck, `depends_on: service_healthy`, init scripts at `/docker-entrypoint-initdb.d/`.
|
||||
|
||||
**Connection management (0.85):** Independent pools — asyncpg `create_pool(min_size=2, max_size=10)` on `app.state` via lifespan; aiosqlite per-call connect. Do not share a session. `command_timeout=10`.
|
||||
|
||||
**Auth stack (0.90 stack / 0.70 rate-limit):** Starlette `SessionMiddleware` (itsdangerous-signed, httpOnly+Secure+SameSite=Strict, 8h) + `argon2-cffi` (argon2id, `check_needs_rehash`) + `slowapi` 5/min in-memory on login route. **Risk: Secure cookie requires TLS — v0.2 pilot is direct-IP no-TLS. Either relax Secure for pilot or add TLS. Flag for PLAN.**
|
||||
|
||||
**Auth dependency pattern (0.90):** One `current_operator` `Depends` + router-level `dependencies=[...]` under `/op`. Migrate to RBAC only when a 2nd role appears.
|
||||
|
||||
**Postgres schema (0.80):** `operators` (id, username, password_hash, created_at), `issued_credentials` (id, learner_ref, vc_payload_json, signature_b64, status, issued_at), `mastery_gate_events` (id, learner_ref, path, week, scenarios_passed_json, rubric_scores_json, gate_opened_at), `cohort_aggregates` (path, week, window_start, window_end, metric, value, cell_suppressed bool — partition by week). `gen_random_uuid()` in PG16 (no extension). **No cross-DB joins via `learner_ref` — `learner_ref` is an opaque string, not a FK.**
|
||||
|
||||
**Migration strategy (0.85):** Staging-CT first, add service + net + volumes, build new image, then `up -d postgres` → `up -d praxis` recreate (~5–15s downtime, SQLite volume untouched → learner path never regresses). Mirror `db/migrate.py` runner for Postgres (separate `db/pg_migrations/` directory).
|
||||
|
||||
**Backup (0.85):** Daily `pg_dump -Fc` to a `pgbackups` named volume, `%u` rolling 7-file retention. Separate from SQLite volume backup. Drill: `pg_restore --clean --if-exists`.
|
||||
|
||||
### D. Anonymization + IRT + Scenario Library
|
||||
|
||||
**k-anonymity (0.85):** k=10 + 7-day trailing window is the right floor for v0.3 (<100 learners). Defer l-diversity/t-closeness until a sensitive attribute enters the cohort schema; defer differential privacy until N>1000. SQL: `COUNT(DISTINCT learner_id) >= 10` with `cell_suppressed` sentinel. Limit to pre-defined 2-D views (path × week, path × outcome) to block differencing attacks.
|
||||
|
||||
**IRT 1PL/Rasch (0.80):** P(success) = logistic(θ − b). θ₀=0, σ²=1 (Gaussian-approximation Bayesian prior). Update: θ ← θ + (outcome − P) × σ²/(σ² + 1) per session; widen σ² after failures. Target P=0.5 for mastery-gate scenarios, P≈0.7 for practice scenarios (per-scenario `irt_target_p` field). θ reliable after ~5–10 sessions. Ship 1PL (2PL needs ~200 responses/item — post-pilot). **D-046 validated: θ in learner-local SQLite.**
|
||||
|
||||
**Scenario library (0.85):** `scenarios/<path>/<id>.yaml` + `scenarios/index.yaml` (slim manifest: id, path, title, difficulty, failure_mode, rubric_criteria, version, author, generated_from). Semver per scenario (MAJOR = rubric_criteria/branch changes invalidate gate evidence). AI variations: `_pending/` dir + mandatory expert review + `generated_from` backref + `intent_hash` for structural-drift detection. Rubric mapping: list of `{criterion_id, weight, evidence_required}`. `MIN_COVERAGE = 2` scenarios per rubric criterion enforced in CI.

## v0.3 Risks (for PLAN stage)
|
||||
|
||||
| ID | Risk | Mitigation | Confidence |
|
||||
|----|------|------------|------------|
|
||||
| R-MAST-01 | N=3 gate too thin for credible credential | Label v0.3 VC as *formative*; reserve high-stakes for v0.9 (N=5-6 + blueprint) | 0.62 |
|
||||
| R-MAST-02 | LLM hallucinates rubric evidence quotes | Fuzzy-match extracted quotes against transcript; reject + re-extract on mismatch | 0.80 |
|
||||
| R-MAST-03 | Rubric weights wrong for non-refund CS archetypes | Per-archetype weights (D-039 amendment); start with refund/complaint, generalize later | 0.70 |
|
||||
| R-VC-01 | No batteries-included Python VC lib → ~200 LOC custom code | Use `eddsa-jcs-2022` cryptosuite (well-specified); pin `pynacl` + `canonicaljson` + `base58`; unit-test signature/verify round-trip | 0.75 |
|
||||
| R-VC-02 | `validUntil` expiry undefined in PRD | Adopt 3-year expiry as default; make configurable; flag in PLAN | 0.60 |
|
||||
| R-AUTH-01 | Secure cookie flag fails without TLS (v0.2 is direct-IP no-TLS) | Relax `Secure` for pilot OR add TLS (Traefik sidecar); flag for PLAN | 0.70 |
|
||||
| R-MT-01 | Postgres-in-LXC resource contention with praxis service | Bump CT memory to 6GB (Postgres ~1GB + praxis ~2GB + build headroom); monitor | 0.65 |
|
||||
| R-MT-02 | Cohort aggregation race on concurrent session-end | Write-time suppression + nightly reconciliation job (D-045); idempotent upserts | 0.70 |
|
||||
| R-IRT-01 | θ unreliable for first ~5-10 sessions (cold start) | Fall back to fixed difficulty (scenario.difficulty) until θ has ≥5 observations; show "calibrating" state to learner | 0.75 |
|
||||
| R-LIB-01 | AI variations drift from expert intent | `intent_hash` structural-drift detection + mandatory expert review before `_pending/` → library promotion | 0.75 |
|
||||
|
||||
---
|
||||
|
||||
## v0.3 Open Questions for PLAN Stage
|
||||
|
||||
1. **Secure cookie + no-TLS pilot:** Relax `Secure` flag for v0.3 pilot (direct-IP), or add a Traefik sidecar for TLS? (R-AUTH-01)
|
||||
2. **CT memory bump:** v0.2 CT is 4GB. Postgres + praxis + build headroom may need 6GB. Confirm via staging-CT test. (R-MT-01)
|
||||
3. **VC `validUntil`:** Adopt 3-year default? Make per-path configurable? (R-VC-02)
|
||||
4. **Phase split:** Is v0.3 one execution phase or 2-3? Scope (mastery core + scenarios + paths + VC + auth + Postgres + dashboard) suggests 2-3 phases. Planner decides.
|
||||
5. **Rubric per-archetype weights:** Ship refund/complaint weights only in v0.3, or author weights for ≥2 archetypes? (R-MAST-03)
|
||||
6. **IRT cold-start UX:** Show "calibrating difficulty" to learner, or hide it? (R-IRT-01)
|
||||
7. **Failure-injection coupling:** RESEARCH confirms D-049 — no active failure injection in v0.3. Confirm no hidden coupling to mastery scoring.

## 1. Review Summary
|
||||
## Review Methodology
|
||||
|
||||
**Verdict: APPROVE_WITH_NOTES**
|
||||
|
||||
The v0.2 milestone delivers a clean, well-documented Proxmox LXC deployment
|
||||
pipeline adapted from the proven coreci pattern. The code is consistently
|
||||
POSIX-sh, idempotent, and backed by a thorough bats suite (121 tests) that
|
||||
exercises the real orchestrator logic with mocked siblings + a live e2e
|
||||
suite gated behind `PRAXIS_E2E_LIVE=1`. The G-101 token-baking fix is
|
||||
correct and the secret-injection chain is consistent across all three
|
||||
layers (lxc-config → install-service → docker-compose env_file).
|
||||
|
||||
Two P0 (blocking) issues were found and **fixed in the working tree**:
|
||||
both were test/code drift where the bats expectations no longer matched the
|
||||
production defaults in `lxc-config.sh` / `.env.example`. After the fixes,
|
||||
all 121 tests pass. Eight P1+ issues are flagged for post-hoc review —
|
||||
none block ship.
|
||||
|
||||
| Severity | Count | Action |
|
||||
|----------|-------|--------|
|
||||
| P0 (critical) | 2 | **Fixed** in working tree (do not commit per instructions) |
|
||||
| P1 (important) | 3 | Flagged for post-hoc review |
|
||||
| P2 (nit) | 5 | Flagged for post-hoc review |
|
||||
Each focus file from the task brief was read in full and cross-referenced against its covering tests, the grill MUST conditions, and the VERIFY.md findings. The 4 grill MUST conditions were independently re-verified in code (not just trusting VERIFY.md). SQL was audited for parameterization. The IRT and scenario-selection code were checked for the claimed O(1) / O(n) complexity. The VC crypto path was checked for argument-order correctness in PyNaCl calls (`VerifyKey.verify(smessage, signature)` — confirmed correct at `issuer.py:156`).

|
||||
## 2. Per-Axis Findings
|
||||
## Per-Persona Findings
|
||||
|
||||
### 2.1 Correctness
|
||||
### 1. Correctness (lead-developer + backend-engineer lens)
|
||||
|
||||
**Correct:**
|
||||
- The deploy orchestrator (`lxc-deploy.sh`) correctly sequences stage →
|
||||
clone → config → start → health-check, with a trap-based rollback that
|
||||
captures `$?` so `set -e` child failures trigger rollback (not just
|
||||
INT/TERM). The trap is installed AFTER `vmid` is resolved and BEFORE
|
||||
clone — so a stage-snippet failure (pre-trap) correctly does not invoke
|
||||
rollback (nothing to roll back). This ordering is documented in the test
|
||||
`stage-snippet fails (set -e) → ... (trap not yet installed)`.
|
||||
- Idempotency (D-027) is correctly implemented: healthy+running → skip;
|
||||
exists+unhealthy → error with `--recreate`/`--reconfigure` guidance
|
||||
(CT left intact); `--reconfigure` re-PUTs config + restarts (no clone);
|
||||
`--recreate` rolls back + redeploys.
|
||||
- `pve_poll` correctly accepts `WARNINGS N` (non-fatal warnings, e.g.
|
||||
systemd 255 nesting hint) in addition to `OK` — this is a real Proxmox
|
||||
behavior that a naive `== "OK"` check would break on.
|
||||
- `health-check.sh` correctly uses `(.inet? // .ip? // empty)` and
|
||||
`grep -v '^$'` to skip `hwaddr` (the P18 coreci bug where `head -1` picked
|
||||
the MAC). The comment documents the fix.
|
||||
- `lxc-config.sh` sed-cleanup pattern is idempotent: removes prior
|
||||
`hookscript:`/`onboot:`/`lxc.environment: PRAXIS|GITEA_TOKEN|DEEPGRAM|
|
||||
CARTESIA|OLLAMA` lines before appending fresh ones. Verified by the
|
||||
`idempotent — re-run does not duplicate` test.
|
||||
- `db/migrate.py` + `db/store.py` both read `PRAXIS_DB_PATH` from env
|
||||
(G-102 fix) — consistent with `docker-compose.yml`'s
|
||||
`PRAXIS_DB_PATH: /app/data/praxis.db` + the volume mount.
|
||||
#### `server/mastery/mastery_score.py` — gate logic
|
||||
|
||||
**Issues:**
|
||||
- **P0-1 (FIXED):** `test/lxc-config.bats:175-181` expected stale defaults
|
||||
(`OLLAMA_BASE_URL=http://ollama.cloudinit.dev:11434`,
|
||||
`DEEPGRAM_LANGUAGE=en-US`, `DEEPGRAM_REGION=us-east-1`) that do NOT
|
||||
match the production code (`lxc-config.sh:66,73,74`), `.env.example`,
|
||||
`docker-compose.yml`, ARCHITECTURE.md, or PLAN.md — all of which use
|
||||
`https://ollama.com/v1`, `en`, `na`. The test was failing. **Fixed:**
|
||||
aligned the test expectations with the production defaults.
|
||||
- **P0-2 (FIXED):** `test/lxc-deploy.bats:222-230` ("PROXMOX_LXC_VMID set
|
||||
→ use the configured VMID") was failing because `lxc-deploy.sh:51-64`
|
||||
sources `~/coreci/.ciagent/.env.secrets` + `${PROJ_ROOT}/.ciagent/
|
||||
.env.secrets` when present, and on a live deploy host those files set
|
||||
`PROXMOX_LXC_VMID=auto` — overriding the test's `PROXMOX_LXC_VMID=300`.
|
||||
The test sandbox did not isolate `HOME` or `PROJ_ROOT`. **Fixed:** the
|
||||
test now exports `HOME="${STUB_DIR}"` so neither secrets file is found,
|
||||
and the deploy script falls back to the exported test env (emitting its
|
||||
"WARNING — not found" message, which is harmless).
|
||||
- **Gate logic (D-032):** `check_gate` at `mastery_score.py:78-86` implements `distinct_passed_count >= 3 AND path_score >= 3.5` — correct. Constants `_GATE_REQUIRED_DISTINCT = 3` and `_GATE_REQUIRED_SCORE = 3.5` are module-level (single source of truth).
|
||||
- **Conjunctive floor:** `compute_scenario_score` at `mastery_score.py:48-54` enforces every criterion ≥ 2 (or the criterion's `conjunctive_floor` if higher) AND mean ≥ 3.0. Professionalism floor (≥2) is honored via `rubric_schema.RubricCriterion.conjunctive_floor`.
|
||||
- **Determinism:** Pure function, no I/O, `round(total, 6)` for stable float comparison. Verified by `test_mastery_integration.py::test_mastery_flow_is_deterministic`.
|
||||
- **Verdict:** ✅ correct.
|
||||
|
||||
### 2.2 Testing
|
||||
#### `server/mastery/irt.py` — theta update + cold-start
|
||||
|
||||
**Correct:**
|
||||
- 121 bats tests across 8 suites (api, lxc-clone, lxc-config, lxc-start,
|
||||
lxc-deploy, health-check, rollback, stage-snippet, firstboot-hook) +
|
||||
1 live e2e suite (gated by `PRAXIS_E2E_LIVE=1`).
|
||||
- Tests exercise the REAL scripts with mocked siblings + a real
|
||||
`ct-exists.sh` (P16) — the orchestrator logic (trap, sequencing,
|
||||
idempotency, flag parsing) is genuinely verified, not stubbed.
|
||||
- Edge cases covered: empty/null UPID, 503 retry exhaustion, WARNINGS
|
||||
exitstatus, hwaddr-vs-IP, idempotent re-run, missing-arg usage errors,
|
||||
env-validation failures, branch-fallback in clone, snippet-already-
|
||||
staged short-circuit.
|
||||
- The `setup_helper.bash` shared sandbox is clean and reusable.
|
||||
- The live e2e suite has a skip guard with a clear message + a teardown
|
||||
that rolls back any leftover CT — safe to run `bats scripts/proxmox/test/`
|
||||
in CI without a live cluster.
|
||||
- **P_success:** `1 / (1 + exp(-(θ−b)))` — standard 1PL/Rasch logistic. Correct.
|
||||
- **update_theta:** Kalman-like Gaussian-approximation update at `irt.py:38-55`:
|
||||
- `prior_precision = 1/σ²`, `info = P(1−P)` (Fisher information for Bernoulli), `new_precision = prior_precision + info`, `new_σ² = 1/new_precision`, `new_θ = θ + new_σ² × (outcome − P)`.
|
||||
- This is the standard 1PL Bayesian update. Correct. σ² shrinks monotonically as observations accumulate.
|
||||
- **Cold-start (R-IRT-01):** `select_scenario` at `irt.py:57-90` falls back to difficulty-based matching when `observations < 5`. Target difficulty = `round(θ + logit(target_p))` clamped to [1,5]. Sound.
|
||||
- **Verdict:** ✅ correct. O(1) per `update_theta` call (verified — single math computation, no loops).
|
||||
|
||||
**Issues:**
|
||||
- **P1-1:** `test/lxc-deploy.bats` sandbox isolation (the P0-2 fix) is
|
||||
fragile: it relies on `HOME` redirect, but `PROJ_ROOT` is computed by
|
||||
`cd "${SCRIPT_DIR}/../.."` where `SCRIPT_DIR` is the sandbox `<ROOT>`.
|
||||
If `<ROOT>`'s parent layout ever changes, `PROJ_ROOT` could resolve to a
|
||||
real repo root. A more robust fix would be to patch the deploy script's
|
||||
`CORECI_SECRETS`/`PRAXIS_SECRETS` paths via an env override (e.g.
|
||||
`PRAXIS_SECRETS_PATH`), or to copy a no-op `.env.secrets` into the
|
||||
sandbox. Flag for post-hoc review.
|
||||
- **P1-2:** No bats test for `timing.sh` (the comment in `lxc-deploy.bats`
|
||||
says "timing.sh itself is tested in timing.bats" but no such file
|
||||
exists in the diff). `timing.sh` has non-trivial logic (the
|
||||
`_TIMING_STARTS` string-map scan + the node_exporter textfile
|
||||
collector). Flag for post-hoc review — add a `timing.bats`.
|
||||
- **P1-3:** No test for `install-service.sh` (runs inside the CT). It
|
||||
writes the env file + systemd unit + starts the service. The
|
||||
`firstboot-hook.bats` verifies it's *invoked* but not its behavior
|
||||
(env-file shape, systemd unit content, idempotency). Flag for post-hoc
|
||||
review — a sandboxed test with mocked `systemctl`/`useradd` would close
|
||||
this gap.
|
||||
#### `server/vc/issuer.py` — JCS + Ed25519
|
||||
|
||||
### 2.3 Security
|
||||
- **JCS canonicalization:** `canonicaljson.encode_canonical_json` at `issuer.py:103-104` — RFC 8785-aligned, deterministic. Tested by `test_vc_issuer.py::test_jcs_canonicalization_determinism` + `test_jcs_key_ordering_is_sorted`.
|
||||
- **eddsa-jcs-2022 proof:** `_compute_hash_data` at `issuer.py:118-125` = `SHA256(canonical_proof) || SHA256(canonical_doc)`. Signed with `signing_key.sign(hash_data).signature` (detached signature). Correct per the cryptosuite spec.
|
||||
- **verify_proof:** at `issuer.py:141-159` reconstructs the same hash and calls `verify_key.verify(hash_data, sig)`. PyNaCl's `VerifyKey.verify(smessage, signature)` arg order is **correct** (verified against the library signature: `verify(self, smessage, signature=None)`). Raises `BadSignatureError` on mismatch → caught → returns False.
|
||||
- **Tamper detection:** re-canonicalizes the unsecured doc (without `proof`) + proof options (without `proofValue`) — any byte flip in the payload changes the canonical bytes → hash mismatch → verify fails. Tested by `test_vc_issuer.py::test_tamper_detection_flipped_byte_fails` + `test_vc_integration.py::test_tamper_payload_verify_fails`.
|
||||
- **Verdict:** ✅ correct. 19 VC tests pass.
|
||||
|
||||
**Correct:**
|
||||
- **G-101 token baking is sound.** `stage-snippet.sh:64` sed-substitutes
|
||||
the literal `${GITEA_TOKEN}` placeholder in the fetched snippet with the
|
||||
real token. The baked snippet lives only in Proxmox snippet storage
|
||||
(`local:snippets/praxis-firstboot.sh`), NOT in git. The hookscript runs
|
||||
on the PVE host where `lxc.environment` is invisible, so baking is the
|
||||
correct mechanism. The `|` sed delimiter avoids `=` (base64 padding) and
|
||||
`/` (common in URLs).
|
||||
- **Secrets are not committed.** `.ciagent/.env.secrets` is mode 0600 and
|
||||
in `.gitignore` (with `!.env.example` exception for the template).
|
||||
`.dockerignore` excludes `.env`, `.env.secrets`, `.env.*` (with
|
||||
`!.env.example`) so secrets never enter the image.
|
||||
- `install-service.sh:65-66` writes `/etc/praxis/server.env` as
|
||||
`root:praxis 0640` — group-readable by the service user, not world.
|
||||
- The `lxc-config.sh` SSH step uses `StrictHostKeyChecking=no` —
|
||||
acceptable for an automated deploy pipeline on a trusted cluster, but
|
||||
see P2-1.
|
||||
- `docker-compose.yml` uses `env_file: required: false` for
|
||||
`/etc/praxis/server.env` so `docker compose config` validates in dev
|
||||
without the file, but `install-service.sh` always creates it before
|
||||
`docker compose up` in production.
|
||||
#### `server/vc/status_list.py` — bitstring revocation
|
||||
|
||||
**Issues:**
|
||||
- **P2-1:** `lxc-config.sh:92` uses `ssh -o StrictHostKeyChecking=no`.
|
||||
This is the standard pattern for automated deploys to a known PVE host,
|
||||
but it accepts any host key on first connect. For defense-in-depth,
|
||||
consider `~/.ssh/known_hosts` pre-seeding or `StrictHostKeyChecking=accept-new`
|
||||
(accepts + pins on first connect, fails on subsequent changes). Nit —
|
||||
the threat model (single-node PVE, operator-controlled) likely accepts
|
||||
this.
|
||||
- **P2-2:** `stage-snippet.sh:46` puts `GITEA_TOKEN` in the Gitea raw URL
|
||||
query string (`?token=${GITEA_TOKEN}`). The comment acknowledges this is
|
||||
"acceptable for an automated deploy pipeline." The token could appear in
|
||||
web server access logs on the Gitea host. Gitea's `?token=` is the
|
||||
documented way to access private repos via raw URL, so this is a known
|
||||
tradeoff. Nit — consider `Authorization: token <TOKEN>` header instead
|
||||
if Gitea supports it for raw file access (would require a two-step
|
||||
fetch: header-based GET to a local file, then upload).
|
||||
- **set/get_status:** bit-twiddling at `status_list.py:35-52` is correct (`byte_pos = idx >> 3`, `bit_pos = idx & 7`).
|
||||
- **get_status bounds check:** `status_list.py:50` returns False if `byte_pos >= len(buf)` — defensive, good.
|
||||
- **allocate_slot:** O(n) scan over the allocation bitstring at `status_list.py:54-72`. For `_MIN_BITS = 131072` (16KB), this is fine in practice (pilot scale). Expansion path (doubling) at `status_list.py:66-72` is correct.
|
||||
- **REQ-NFR-VC-02 (revocation latency):** status list fetched from SQLite on every verify call (`verification.py:47-48`) — no cache. Confirmed.
|
||||
- **Verdict:** ✅ correct.
|
||||
|
||||
### 2.4 Performance
|
||||
#### `server/session_recorder.py` — mastery flow wiring
|
||||
|
||||
**Correct:**
|
||||
- **Dockerfile layer caching is correct.** Stage 1: `COPY package.json
|
||||
package-lock.json` → `npm ci` → `COPY client/` → `npm run build`. Stage
|
||||
2: `COPY pyproject.toml README.md` → `pip install .` → `COPY server/
|
||||
scenarios/ db/` → `COPY --from=client-builder`. Deps are cached; source
|
||||
changes don't invalidate the pip/npm layers. This is the G-105 fix and
|
||||
it's done right.
|
||||
- Multi-stage build keeps the final image small (no node, no build tools,
|
||||
no client source — only the built `dist`).
|
||||
- `pve_get` 503 retry is bounded (3 attempts, 2s backoff) — used only for
|
||||
idempotent reads, NOT mutating calls.
|
||||
- `pve_poll` is bounded (120 × 2s = 4 min max) — prevents infinite hangs.
|
||||
- `health-check.sh` polls with `--connect-timeout 2` per attempt + a
|
||||
600s total budget (G-104 fix for Docker build margin).
|
||||
- **Sequencing:** `run_mastery_flow` at `session_recorder.py:154-311` correctly sequences: extract → score → IRT update → progress upsert → gate event record → VC issuance.
|
||||
- **scoring_inconclusive path:** at `session_recorder.py:185-192` short-circuits all downstream steps and surfaces `retry_advised: True`. No score, no gate event, no progress change, no IRT update. Grill Axis 4 MUST #3 satisfied. Tested by `test_mastery_integration.py::test_mastery_flow_scoring_inconclusive_no_score_no_gate_event`.
|
||||
- **VC issuance:** `session_recorder.py:276-293` — `path_complete = gate_open and new_week >= 6`; on True, lazy-imports `server.vc.issuer.issue_credential`. `ImportError` swallowed (SLICE-09-independent ship); `Exception` logged (issuance failure doesn't crash mastery flow). Grill Axis 8 MUST satisfied.
|
||||
- **Outer guard:** `_run_mastery_flow_guarded` at `session_recorder.py:148-152` wraps the whole flow in try/except — mastery failure never crashes session end. Good isolation.
|
||||
- **P1 finding (P1-4, carried from VERIFY.md):** `compute_path_score` at `session_recorder.py:209-211` uses only the current session's score, not the cumulative mean over all passing sessions. The gate still works (distinct-count is the primary gate; the score threshold is secondary and the current-session score is a reasonable proxy). The in-code comment at `session_recorder.py:212-213` acknowledges this. Flag for v0.4: fold in prior passing scores from `mastery_progress.scenarios_passed_json`.
|
||||
- **Verdict:** ✅ correct (with P1-4 noted).
|
||||
|
||||
**Issues:**
|
||||
- **P2-3:** `Dockerfile:39` runs `pip install --no-cache-dir .` with only
|
||||
`pyproject.toml` + `README.md` copied. `pip install .` on a
|
||||
pyproject-only context (no source) works because setuptools reads
|
||||
`pyproject.toml` for metadata + deps, but it will FAIL if any dep tries
|
||||
to import the package during install (none do here — fastapi/uvicorn/
|
||||
pipecat don't import praxis). This is correct for now but fragile if a
|
||||
future dep adds a `praxis` import in its setup. Nit — consider
|
||||
`pip install --no-cache-dir -e .` after copying source, or split deps
|
||||
into a requirements layer. Documented as the G-105 tradeoff.
|
||||
- **P2-4:** `stage-snippet.sh:88-93` spawns a `python3 -m http.server` +
|
||||
a `( sleep 60 && kill )` safety net. The server is killed after the
|
||||
upload completes (line 117), but the `sleep 60` subprocess is NOT
|
||||
killed — it lingers for up to 60s after the script exits. Harmless (it
|
||||
just tries to kill an already-dead PID), but slightly sloppy. Nit —
|
||||
capture the sleep's PID and kill it on EXIT.
|
||||
### 2. Testing (backend-engineer + lead-developer lens)
|
||||
|
||||
### 2.5 Maintainability
|
||||
#### Grill MUST conditions — independently re-verified in code
|
||||
|
||||
**Correct:**
|
||||
- Every script has a clear header comment block: purpose, env vars
|
||||
(required + optional with defaults), args, exit codes. The
|
||||
`lxc-config.sh` header documents the G-101 reasoning (why SSH vs REST
|
||||
for hookscript/lxc.environment) — excellent for future readers.
|
||||
- Consistent with coreci patterns (sourced `api.sh`, `pve_env` validation,
|
||||
UPID polling, trap-based rollback) while cleanly diverging where praxis
|
||||
differs (no proxy tier, Docker-in-LXC vs Go binary, praxis env var
|
||||
names). The divergences are documented in test comments ("Praxis v0.2
|
||||
vs coreci key differences asserted here").
|
||||
- `timing.sh` is a clean adaptation of the coreci timing helper with
|
||||
praxis-prefixed metrics. The POSIX-sh string-map (no associative arrays)
|
||||
is well-commented.
|
||||
- `e2e-deploy.sh` is a good integration capstone — loads secrets, runs
|
||||
the deploy, verifies /health + client HTML serving.
|
||||
| # | Grill MUST | Test evidence (verified in code) | Verdict |
|
||||
|---|-----------|----------------------------------|---------|
|
||||
| Axis 3 #1 | VC interop test exists | `tests/test_vc_interop.py` (153 LOC): JCS canonicalization is valid JSON, signature is 64-byte base64, W3C VC 2.0 schema conformance (@context, type, issuer, validFrom/validUntil, credentialSubject, credentialTier, proof fields). Staging-gated `test_full_w3c_vc_interop_validation` for extended self-check. | ✅ covered (P1-3: live external-verifier run is post-hoc) |

|
||||
| Axis 4 #1 | `credentialTier: "formative"` in payload | `test_vc_issuer.py::test_credential_tier_is_formative_in_payload` asserts both payload-level and credentialSubject-level. `test_vc_integration.py::test_issue_and_verify_valid` asserts response `credentialTier == "formative"`. | ✅ covered |
|
||||
| Axis 4 #3 | `scoring_inconclusive` fallback | `test_mastery_integration.py::test_mastery_flow_scoring_inconclusive_no_score_no_gate_event` — 3 bad-quote responses → inconclusive, no ability/progress/gate-event rows. `test_evidence_extractor_integration.py` covers the extractor-level inconclusive path. | ✅ covered |
|
||||
|
||||
**Issues:**
|
||||
- **P2-5:** `lxc-config.sh:124-130` builds a remote shell snippet via
|
||||
`ssh ... "conf='${conf_file}'; sed -i '...'; cat >> ..."`. The
|
||||
`sed -i` expression uses `;`-separated delete patterns
|
||||
(`/^hookscript:/d;/^onboot:/d;/^lxc\.environment: PRAXIS/d;...`).
|
||||
This is correct but hard to read. A future maintainer adding a new env
|
||||
var group (e.g. `WHISPER_`) must update BOTH the `append_lines`
|
||||
function AND the sed delete pattern, or risk stale lines surviving
|
||||
re-config. Consider a single `sed -i '/^lxc\.environment:/d'` (drop
|
||||
ALL lxc.environment lines) since `append_lines` always re-emits the
|
||||
full set. Nit — document the dual-update requirement in a comment.
|
||||
**4/4 grill MUST conditions tested.** Matches VERIFY.md L2.5.
|
||||
|
||||
#### Untested critical paths
|
||||
|
||||
- **P1 gap (new finding): HTTP route wiring untested.** The `/vc/verify/{credential_id}` route at `server/__main__.py:124-136` is NOT tested via FastAPI TestClient / ASGI transport. The underlying `verify_credential()` function is well-tested (`test_vc_integration.py`, `test_vc_key_rotation_drill.py`), but the route registration, 404-on-not-found behavior, and the `_store.init()` call in the route handler are untested. A route-registration regression (e.g., route mounted after StaticFiles catch-all at `__main__.py:146`, shadowing the API route) would not be caught. Recommended: add one `httpx.AsyncClient` + ASGI transport test that hits `GET /vc/verify/<unknown>` → 404 and `GET /vc/verify/<valid>` → 200 with the formative tier.
|
||||
- **P2 gap: status list expansion path untested.** `BitstringStatusList.allocate_slot` at `status_list.py:66-72` doubles the bitstring when all slots are full. This expansion branch is not exercised by any test (pilot scale never fills 131072 slots). Low risk, but worth a unit test that forces expansion with a tiny `_MIN_BITS` override.
|
||||
- **P2 gap: `get_status` on uninitialized list.** If `get_status(idx)` is called before any `set_status` or `allocate_slot`, `_load` initializes an all-zero bitstring → returns False. This is correct behavior but untested explicitly.
|
||||
|
||||
### 3. Security (security-engineer lens)
|
||||
|
||||
#### `server/vc/verification.py` — public endpoint injection
|
||||
|
||||
- **credential_id injection:** The `credential_id` path parameter at `__main__.py:125` flows to `store.get_credential(cred_id)` at `store.py:372-381`, which uses a parameterized query (`WHERE id = ?`). No SQL injection. FastAPI does not apply a regex constraint on the path param, but SQLite handles arbitrary strings safely (returns None for non-matching ids → 404).
|
||||
- **No PII leak:** `verification.py:53-73` returns only `{valid, status, issuer, credential{id,type,validFrom,validUntil}, mastery{skill,level,path,rubricScore,scenariosPassed,completedWeeks}, credentialTier, verifiedAt}`. `credentialSubject.id` is `urn:uuid:<learner_ref>` (opaque). No email/name/phone/address. Confirmed.
|
||||
- **Verdict:** ✅ secure (no injection vector).
|
||||
|
||||
#### `server/mastery/evidence_extractor.py` — LLM prompt injection
|
||||
|
||||
- **Vector:** transcript turns injected verbatim into the user message at `evidence_extractor.py:86`. A malicious learner could attempt prompt injection in spoken turns ("ignore previous instructions...").
|
||||
- **Mitigations (all verified in code):**
|
||||
1. System prompt is fixed and authoritative (`evidence_extractor.py:78-84`).
|
||||
2. Output is JSON-schema-validated (`_parse_evidence_json` at `evidence_extractor.py:96-119` rejects non-list, unknown `criterion_id`, schema-invalid items).
|
||||
3. **Fuzzy-match gate** at `evidence_extractor.py:180` — an injected "quote" that isn't in the transcript is rejected. This is the strongest mitigation: even if the LLM obeys an injection, the forged quote must actually appear in the learner's spoken turns to pass.
|
||||
- **Verdict:** ✅ secure. The fuzzy-match gate blocks the highest-impact injection (faking evidence to boost a score).
|
||||
|
||||
#### `db/store.py` — SQL injection in new async methods
|
||||
|
||||
- **Audit:** all 14 v0.3 async methods (`get_ability`, `upsert_ability`, `get_progress`, `upsert_progress`, `record_gate_event`, `list_gate_events`, `init_issuer_key`, `get_active_signing_key_row`, `get_public_key_row`, `set_issuer_key_superseded`, `insert_credential`, `get_credential`, `set_credential_status`, `get_status_list`, `upsert_status_list`) use `?` placeholder parameterization. No f-string SQL, no string concatenation in queries. Grep for `f".*SELECT|f".*INSERT|f".*UPDATE|f".*WHERE` in `server/` and `db/` returned zero matches.
|
||||
- **Verdict:** ✅ no SQL injection.
|
||||
|
||||
### 4. Performance (backend-engineer lens)
|
||||
|
||||
#### `server/mastery/irt.py` — O(1) verification
|
||||
|
||||
- **`update_theta`:** 1 division, 1 multiplication, 1 exp, 1 subtraction — O(1). Confirmed. REQ-NFR-IRT-01 (<100ms) trivially satisfied (sub-microsecond).
|
||||
- **`P_success`:** O(1).
|
||||
- **`select_scenario` cold-start:** O(n) over path scenarios (n ≈ 6 in v0.3). Fine.
|
||||
- **Verdict:** ✅ O(1) per update as required.
|
||||
|
||||
#### `server/scenarios/library.py` — `select_for_theta` O(n) verification
|
||||
|
||||
- **`select_for_theta` at `library.py:143-167`:** single `for e in entries` loop with `abs(e.difficulty - target_b)` — O(n), NOT O(n²). No nested loops. `list_by_path` at `library.py:126-133` is also O(n) (one pass, though it calls `self.get(e.id)` per entry which is cached after first load).
|
||||
- **Minor note (P2):** `list_by_path` at `library.py:129-130` calls `self.get(e.id)` (which loads + caches the scenario YAML) for every entry just to read `s.path`. For n=6 this is negligible, but for a large library this could be optimized by storing `path` in the `IndexEntry` itself (the manifest already has it). Not a v0.3 concern.
|
||||
- **Verdict:** ✅ O(n), not O(n²).
|
||||
|
||||
### 5. Maintainability (lead-developer lens)
|
||||
|
||||
#### `server/mastery/` module organization
|
||||
|
||||
- Clean separation: `rubric_schema.py` (model), `rubric_loader.py` (I/O), `rubric_scorer.py` (deterministic scoring), `evidence_extractor.py` (LLM extraction), `mastery_score.py` (gate logic), `irt.py` (IRT engine). Each module is single-responsibility, <120 LOC, typed, with `__all__` exports.
|
||||
- **Verdict:** ✅ well-organized.
|
||||
|
||||
#### `server/vc/` module organization
|
||||
|
||||
- Clean separation: `issuer.py` (payload + signing + issuance), `issuer_keys.py` (key management + encryption), `status_list.py` (revocation), `verification.py` (public verify + revoke). `CREDENTIAL_TIER = "formative"` is a module-level constant in `issuer.py:34` — single source of truth.
|
||||
- **Minor coupling smell (P2):** `issuer_keys._fetch_private_key_enc` at `issuer_keys.py:92-99` reaches into `store._connect()` (a private method) instead of using a public `store.get_private_key_enc(key_id)` method. This couples `issuer_keys` to `PraxisStore`'s internal connection management. Not a bug, but a small abstraction leak. Recommended: add a public `store.get_issuer_key_row(key_id)` method that returns the full row.
|
||||
- **Verdict:** ✅ well-organized (with P2 coupling note).
|
||||
|
||||
### 6. Adversarial (security-engineer + red-team lens)
|
||||
|
||||
#### `/vc/verify` public endpoint — rate-limiting
|
||||
|
||||
- **P1 (carried from VERIFY.md P1-1):** Endpoint is public + unauthenticated (D-043, by design — third-party verifiers must reach it). No rate limiting in v0.3. A flood of verify requests would each hit SQLite (`get_credential` + `get_public_key_row` + `get_status_list` = 3 queries per verify). Acceptable for pilot (single-deploy, low traffic). Flag for v0.4: add slowapi rate-limit (60 req/min/IP) on `/vc/verify/*`.
|
||||
|
||||
#### Issuer key management — `PRAXIS_VC_ISSUER_KEY` fallback
|
||||
|
||||
- **P1 (carried from VERIFY.md P1-2):** `_load_root_key` at `issuer_keys.py:25-31` silently falls back to `nacl.utils.random(...)` if `PRAXIS_VC_ISSUER_KEY` is unset. On a deploy where the env var is missing:
|
||||
- First boot: `init_issuer_key` generates a key, encrypts with the random root key, stores ciphertext. Issuance works *within this process*.
|
||||
- Restart: new random root key → `get_active_signing_key` decrypts the old ciphertext with the new key → `nacl.secret.SecretBox.decrypt` raises `CryptoError` → issuance fails with a confusing error.
|
||||
- **Old VCs still verify** (public key is stored unencrypted) — no data loss, no security hole.
|
||||
- This is a **P1 operational footgun**, not a P0. The failure mode is "new issuance breaks after restart" not "credentials become invalid" or "keys leak." Recommended v0.4 fix: fail fast at startup if `PRAXIS_VC_ISSUER_KEY` is unset (raise `RuntimeError`), or persist the root key to a secrets manager on first init.
|
||||
|
||||
- **No other adversarial vectors found.** Issuance is server-side only (learner code never calls `issue_credential` directly — only `session_recorder.run_mastery_flow` after gate-open). Key rotation marks old keys `superseded`, not deleted — old VCs verify against archived public keys. Tested by `test_vc_key_rotation_drill.py`.
|
||||

|

## 3. P0 Issues (Critical — Fixed in Working Tree)
|
||||
## P0 Fixes Applied
|
||||
|
||||
### P0-1: lxc-config.bats expected stale OLLAMA/DEEPGRAM defaults (FAILING TEST)
|
||||
- **File:** `scripts/proxmox/test/lxc-config.bats:175-181`
|
||||
- **Symptom:** Test 76 failed: `grep '^lxc.environment: OLLAMA_BASE_URL=http://ollama.cloudinit.dev:11434$'` did not match.
|
||||
- **Root cause:** The test expected `http://ollama.cloudinit.dev:11434`,
|
||||
`en-US`, `us-east-1` — stale values from an earlier draft. The
|
||||
production code (`lxc-config.sh:66,73,74`), `.env.example`,
|
||||
`docker-compose.yml`, ARCHITECTURE.md, and PLAN.md all consistently use
|
||||
`https://ollama.com/v1`, `en`, `na`. The test drifted.
|
||||
- **Fix applied:** Aligned the test grep patterns with the production
|
||||
defaults (`https://ollama.com/v1`, `en`, `na`).
|
||||
**None.** No P0 (critical bug / security hole) fixes were required. The codebase passes all 238 tests, all 4 grill MUST conditions are satisfied and tested, all SQL is parameterized, the VC crypto path is correct (PyNaCl arg order verified), the IRT and gate logic are mathematically sound, and the `scoring_inconclusive` fallback correctly avoids silent fail-to-zero.
|
||||
|
||||
### P0-2: lxc-deploy.bats "PROXMOX_LXC_VMID set" test failed due to secrets-file leakage (FAILING TEST)
|
||||
- **File:** `scripts/proxmox/test/lxc-deploy.bats:222-230`
|
||||
- **Symptom:** Test 88 failed: `grep 'deploy: using configured VMID 300'` did not match.
|
||||
- **Root cause:** `lxc-deploy.sh:51-64` sources `~/coreci/.ciagent/.env.secrets`
|
||||
and `${PROJ_ROOT}/.ciagent/.env.secrets` when present. On a live deploy
|
||||
host (this review ran on the actual cluster), the coreci secrets file
|
||||
sets `PROXMOX_LXC_VMID=auto`, overriding the test's
|
||||
`PROXMOX_LXC_VMID=300`. The test sandbox did not isolate `HOME` or
|
||||
`PROJ_ROOT`, so the real secrets file leaked into the test.
|
||||
- **Fix applied:** The test now exports `HOME="${STUB_DIR}"` so neither
|
||||
secrets file is found; the deploy script falls back to the exported
|
||||
test env (emitting its "WARNING — not found" message, which is harmless
|
||||
and does not affect the test assertions). All other lxc-deploy.bats
|
||||
tests continue to pass with this change.
|
||||
|
||||
**After both fixes: 121/121 bats tests pass.**
|
||||
The two issues flagged as P1 in VERIFY.md (rate-limiting, root-key fallback) were re-confirmed as **P1, not P0**:
|
||||
- Rate-limiting: acceptable for pilot scale, no security hole (public verify is read-only, no PII leak).
|
||||
- Root-key fallback: operational footgun, not a security hole (old VCs remain valid; only new issuance breaks after restart with missing env).
|
||||
|
||||

|
||||
|
||||
## 4. P1+ Issues (Flagged for Post-Hoc Review)
|
||||
## P1+ Flags (post-hoc review — non-blocking for v0.1.4 ship)
|
||||
|
||||
### P1-1: lxc-deploy.bats sandbox isolation is fragile
|
||||
- **File:** `scripts/proxmox/test/lxc-deploy.bats` (the P0-2 fix)
|
||||
- **Issue:** The `HOME` redirect works but relies on `PROJ_ROOT` (computed
|
||||
via `cd "${SCRIPT_DIR}/../.."`) resolving to a path with no
|
||||
`.ciagent/.env.secrets`. If the sandbox layout changes, this could
|
||||
break. A more robust fix: add an env override to `lxc-deploy.sh` (e.g.
|
||||
`PRAXIS_SECRETS_PATH` / `CORECI_SECRETS_PATH`) so tests can point at a
|
||||
no-op file, or copy a no-op `.env.secrets` into the sandbox.
|
||||
|
||||
### P1-2: No bats test for timing.sh
|
||||
- **File:** (missing) `scripts/proxmox/test/timing.bats`
|
||||
- **Issue:** `lxc-deploy.bats:104-107` stubs `timing.sh` to a no-op and
|
||||
comments "timing.sh itself is tested in timing.bats" — but no
|
||||
`timing.bats` exists in the diff. `timing.sh` has non-trivial logic
|
||||
(the `_TIMING_STARTS` string-map scan, duration computation, optional
|
||||
node_exporter textfile collector). Add a `timing.bats` covering:
|
||||
start/end pairing, duration math, stray `timing_end` with no start
|
||||
(no-op), textfile collector write when `NODE_TEXTFILE_COLLECTOR_DIR`
|
||||
is set + writable.
|
||||
|
||||
### P1-3: No test for install-service.sh
|
||||
- **File:** `scripts/install-service.sh`
|
||||
- **Issue:** `firstboot-hook.bats` verifies `install-service.sh` is
|
||||
*invoked* via `pct exec`, but does not test its behavior: env-file
|
||||
shape (`/etc/praxis/server.env` content), systemd unit content, user
|
||||
creation, idempotency. A sandboxed test with mocked `systemctl`/
|
||||
`useradd`/`apt-get` would close this gap and catch drift in the env-file
|
||||
format (which must match `docker-compose.yml`'s `env_file` expectations).
|
||||
|
||||
### P2-1: ssh StrictHostKeyChecking=no
|
||||
- **File:** `scripts/proxmox/lxc-config.sh:92`
|
||||
- **Issue:** Accepts any host key on first connect. Consider
|
||||
`StrictHostKeyChecking=accept-new` (pins on first connect, fails on
|
||||
subsequent changes) for defense-in-depth. Acceptable for the current
|
||||
single-node-PVE threat model.
|
||||
|
||||
### P2-2: GITEA_TOKEN in Gitea raw URL query string
|
||||
- **File:** `scripts/proxmox/stage-snippet.sh:46`
|
||||
- **Issue:** `?token=${GITEA_TOKEN}` could appear in Gitea access logs.
|
||||
Documented as an accepted tradeoff. Consider header-based auth if Gitea
|
||||
supports it for raw file access.
|
||||
|
||||
### P2-3: Dockerfile pip install . without source
|
||||
- **File:** `Dockerfile:38-39`
|
||||
- **Issue:** `pip install --no-cache-dir .` with only `pyproject.toml` +
|
||||
`README.md` works because no dep imports `praxis` at install time.
|
||||
Fragile if a future dep does. Documented as the G-105 tradeoff.
|
||||
|
||||
### P2-4: stage-snippet.sh sleep 60 subprocess lingers
|
||||
- **File:** `scripts/proxmox/stage-snippet.sh:91`
|
||||
- **Issue:** The `( sleep 60 && kill )` safety-net subprocess is not
|
||||
killed when the HTTP server exits. It lingers up to 60s trying to kill
|
||||
an already-dead PID. Harmless but sloppy. Capture + kill the sleep PID
|
||||
on EXIT.
|
||||
|
||||
### P2-5: lxc-config.sh sed delete pattern must be kept in sync with append_lines
|
||||
- **File:** `scripts/proxmox/lxc-config.sh:127`
|
||||
- **Issue:** The `sed -i '/^hookscript:/d;/^onboot:/d;/^lxc\.environment:
|
||||
PRAXIS/d;...'` pattern must be updated whenever a new env-var GROUP is
|
||||
added to `append_lines`, or stale lines survive re-config. Consider a
|
||||
single `sed -i '/^lxc\.environment:/d'` (drop ALL lxc.environment lines)
|
||||
since `append_lines` always re-emits the full set. Document the
|
||||
dual-update requirement.
|
||||
| ID | Flag | Severity | Location | Recommended action | Origin |
|
||||
|----|------|----------|----------|--------------------|--------|
|
||||
| **P1-1** | `/vc/verify` public + unauthenticated, no rate limiting → DoS vector (3 SQLite queries per verify) | P1 | `server/vc/verification.py`, `server/__main__.py:124` | v0.4: add slowapi rate-limit (60 req/min/IP) on `/vc/verify/*`. Acceptable for pilot. | VERIFY.md P1-1 (re-confirmed) |
|
||||
| **P1-2** | `_load_root_key()` silent random fallback when `PRAXIS_VC_ISSUER_KEY` unset → cross-restart issuance breaks silently (old VCs still verify) | P1 | `server/vc/issuer_keys.py:25-31` | v0.4: fail fast at startup if env unset (raise `RuntimeError`), or persist root key to secrets manager. | VERIFY.md P1-2 (re-confirmed) |
|
||||
| **P1-3** | VC interop test validates W3C schema + crypto format but does not invoke a live external W3C verifier (grill Axis 3 MUST #1 strictest bar) | P1 | `tests/test_vc_interop.py:128-153` | Before v0.3 milestone ship (v0.1.5): schedule staging run with `@digitalcredentials/vc` or `digitalbazaar/vc-verifier`. Schema + format validation is sufficient for v0.1.4 patch ship. | VERIFY.md P1-3 (re-confirmed) |
|
||||
| **P1-4** | `compute_path_score` uses only current session's score, not cumulative mean over all passing sessions | P1 | `server/session_recorder.py:209-211` | v0.4: fold in prior passing scores from `mastery_progress.scenarios_passed_json`. Gate still works (distinct-count is primary). | VERIFY.md P1-4 (re-confirmed) |
|
||||
| **P1-5 (new)** | HTTP route `/vc/verify/{credential_id}` wiring untested (no TestClient/ASGI test) — route registration, 404 behavior, `_store.init()` in handler not exercised | P1 | `server/__main__.py:124-136`, `tests/` | v0.4 (or before v0.1.5): add one `httpx.AsyncClient` + ASGI transport test: `GET /vc/verify/<unknown>` → 404, `GET /vc/verify/<valid>` → 200 with `credentialTier: formative`. Catches route-shadowing regressions (StaticFiles catch-all at `__main__.py:146` could shadow API routes if ordering changes). | New finding |
|
||||
| **P2-1** | No max-transcript-length guard in evidence extraction → long sessions could exceed model context window | P2 | `server/mastery/evidence_extractor.py:75-93` | Future: truncation or chunking for >30-min sessions. Not a v0.3 blocker. | VERIFY.md P2-1 (carried) |
|
||||
| **P2-2 (new)** | `BitstringStatusList.allocate_slot` expansion branch (doubling when full) untested; `issuer_keys._fetch_private_key_enc` reaches into `store._connect()` (private method) — abstraction leak | P2 | `server/vc/status_list.py:66-72`, `server/vc/issuer_keys.py:92-99` | Future: add a forced-expansion unit test with tiny `_MIN_BITS`; add a public `store.get_issuer_key_row(key_id)` method to remove the private-method coupling. | New finding |
|
||||

|
||||
|
||||
## 5. Positive Observations
|
||||
## Final Verdict: **APPROVE_WITH_NOTES**
|
||||
|
||||
1. **Test suite quality is high.** 121 bats tests exercising real
|
||||
orchestrator logic (not stubbed) with a shared sandbox helper, edge
|
||||
cases (503 retry, WARNINGS exitstatus, hwaddr-vs-IP, idempotent
|
||||
re-run, empty/null UPID), and a properly-gated live e2e suite. This is
|
||||
the strongest part of the milestone.
|
||||
v0.3 (P0 + P1) is verified across all 6 persona lenses:
|
||||
|
||||
2. **G-101 token baking is correct and well-documented.** The
|
||||
`stage-snippet.sh` sed substitution + the `firstboot-hook.sh`
|
||||
`${GITEA_TOKEN}` placeholder + the `lxc-config.sh` header explaining
|
||||
why SSH is needed (lxc.environment invisible to host-side hookscript)
|
||||
form a coherent, secure secret-injection chain.
|
||||
- ✅ **Correctness:** gate logic (D-032 ≥3 distinct AND ≥3.5), IRT Kalman update, JCS+Ed25519 signing/verification, status list bit-twiddling, mastery flow wiring, `scoring_inconclusive` short-circuit — all correct. PyNaCl `VerifyKey.verify(smessage, signature)` arg order confirmed.
|
||||
- ✅ **Testing:** 238 passed / 10 skipped. 4/4 grill MUST conditions independently re-verified as tested. P1-5 flags the untested HTTP route wiring (function-level tests are sufficient for v0.1.4).
|
||||
- ✅ **Security:** no SQL injection (all 14 new async methods parameterized), no PII leak on `/vc/verify`, LLM prompt injection mitigated by fuzzy-match gate. P1-1 (rate-limit) and P1-2 (root-key fallback) re-confirmed as P1, not P0.
|
||||
- ✅ **Performance:** `irt.update_theta` is O(1); `library.select_for_theta` is O(n) (not O(n²)); `status_list.allocate_slot` is O(n) over 131072 bits (acceptable).
|
||||
- ✅ **Maintainability:** `server/mastery/` and `server/vc/` are cleanly separated, single-responsibility, typed, <120 LOC per module. Minor P2 coupling note on `issuer_keys._fetch_private_key_enc`.
|
||||
- ✅ **Adversarial:** issuance is server-side only (gated by mastery flow); key rotation archives (not deletes) old keys; public verify is read-only with no PII. P1-1/P1-2 are the only attack-surface flags, both acceptable for pilot.
|
||||
|
||||
3. **Idempotency is thorough.** `lxc-deploy.sh` (CT exists + healthy →
|
||||
skip; unhealthy → guidance + `--recreate`/`--reconfigure`), `lxc-config.sh`
|
||||
(sed-cleanup before append), `rollback.sh` (404-tolerant), `firstboot-hook.sh`
|
||||
(skip if `/opt/praxis/.git` + service active), `stage-snippet.sh`
|
||||
(snippet-already-staged short-circuit). Every layer is re-runnable.
|
||||
**0 P0 fixes applied.** No critical bugs or security holes found. The 5 P1 flags + 2 P2 notes are non-blocking and tracked for v0.4 / the v0.1.5 milestone ship. The v0.1.4 patch ship is **unblocked**.
|
||||
|
||||
4. **Dockerfile layer caching is correct (G-105).** Deps installed before
|
||||
source copy; multi-stage build keeps the image small. The
|
||||
`client/package.json` → `npm ci` → `client/` pattern in Stage 1 mirrors
|
||||
the server pattern.
|
||||
|
||||
5. **Consistent with coreci, cleanly divergent where needed.** The
|
||||
`api.sh` / `pve_env` / `pve_poll` / trap-rollback patterns are
|
||||
inherited from the proven coreci pipeline; the divergences (no proxy
|
||||
tier, Docker-in-LXC vs Go binary, praxis env var names, 600s health
|
||||
timeout) are documented in script headers + test comments.
|
||||
|
||||
6. **Shellcheck-clean.** All scripts pass `shellcheck` with only
|
||||
expected SC1090 (non-constant source) warnings on the dynamic
|
||||
`. "$SECRETS"` sourcing.
|
||||
|
||||
7. **Documentation is excellent.** Every script has a purpose + env +
|
||||
args + exit-code header. The `lxc-config.sh` header explains the
|
||||
REST-vs-SSH split for root-only fields. The `rollback.sh` header notes
|
||||
the proxy-tier removal for future readers.
|
||||
**Recommended next steps:**
|
||||
1. Proceed to P2 (final audit + milestone ship).
|
||||
2. Before v0.1.5: schedule the live external-verifier interop run (P1-3) + add the HTTP route test (P1-5).
|
||||
3. v0.4: address P1-1 (rate-limit), P1-2 (root-key fail-fast), P1-4 (path-score cumulative mean).

# Praxis — Roadmap
|
||||
|
||||
**Milestone:** v0.2 (Proxmox LXC deployment)
|
||||
**Status:** phase 1 complete — P2 review/ship in-progress
|
||||
**Milestone:** v0.4 (Operator tier — cohort dashboard, auth, Postgres) — active
|
||||
**Status:** phase 0 — specify (active milestone)
|
||||
**Previous milestone:** v0.3 (Mastery scoring + competency rubrics + verifiable credentials) — complete, tagged v0.1.5, release #380, merged to main
|
||||
|
||||
## Milestone Philosophy
|
||||
|
||||
v0.2 deploys praxis into a Proxmox LXC container, reusing and adapting the battle-tested deployment toolkit from `~/coreci/scripts/proxmox/`. The v0.1 voice loop becomes deployable infrastructure. v1.0 is reserved for a working, tested product and is a future milestone.
|
||||
v0.4 activates the operator tier deferred from v0.3 per the grill's binding verdict (GRILL-v0.3.md Axis 2 — the operator tier was originally v0.8 on this roadmap; pulling it into v0.3 created a 2-milestone program disguised as one). v0.4 layers the operator surface on top of the v0.3 mastery/VC/scenario work: a Postgres store in the existing LXC CT, operator auth (argon2id session cookies), a cohort aggregation pipeline (k-anonymity ≥ 10, 7-day windows), and a React cohort dashboard served by the same FastAPI server. The learner-facing surface carries forward unchanged (SQLite, voice loop, mastery gates, VC issuance). The VC issuer key store migrates from SQLite to operator-tier Postgres + secrets (D-042).
|
||||
|
||||
## v0.2 Phases (2 phases)
|
||||
## v0.4 Phases
|
||||
|
||||
### Phase 0 — Pre-Execution (in-progress — this phase)
|
||||
|
||||
**Branch:** `phase/00-pre-execution` → merged to `milestone/v0.4-operator-tier`
|
||||
**Ship target:** `v0.1.6` (patch release on v0.3's v0.1.x line — NFR/docs milestone type)
|
||||
**Status:** in-progress (SPECIFY)
|
||||
|
||||
Pipeline stages: SPECIFY → CLARIFY → RESEARCH → PLAN → GRILL → SHIP
|
||||
|
||||
**Goal:** Produce all `.ciagent/` planning artifacts for v0.4: activated requirements (REQ-MT-01/02, REQ-AUTH-01, REQ-DASH-01 + 4 NFRs), research-grounded Postgres-in-LXC + k-anonymity + argon2id + React-dashboard architecture, persona roster (frontend-engineer + data-engineer reactivated, security-engineer retained), vertical-slice plan for P1/P2.
|
||||
|
||||
**Deliverables:**
|
||||
- PROJECT.md (v0.4 scope validated; operator tier activated)
|
||||
- REQUIREMENTS.md (v0.4 active REQ-IDs = 8; v0.3 marked complete)
|
||||
- ARCHITECTURE.md (operator Postgres + auth + cohort dashboard + aggregation pipeline added to v0.3 topology)
|
||||
- PERSONAS.md (v0.4 roster — frontend-engineer + data-engineer reactivated for dashboard + Postgres; security-engineer retained for auth/crypto; devops-engineer for Postgres-in-LXC)
|
||||
- GRILL-v0.4.md (adversarial review — auth + PII surface warrants grill)
|
||||
- Phase 1 + Phase 2 plans (vertical slices with wave ordering)
|
||||
|
||||
### Phase 1 — Operator Foundation (Postgres + Auth) (planned)
|
||||
|
||||
**Branch:** `phase/01-operator-foundation` → merged to `milestone/v0.4-operator-tier`
|
||||
**Ship target:** `v0.1.7` (patch release, feature milestone type)
|
||||
**Status:** planned
|
||||
|
||||
**Goal:** Operator-tier Postgres 16 running as a second Docker service in the existing LXC CT (internal network only), operator auth (argon2id session cookies, single `operator` role, login rate-limited), VC issuer key store migrated to Postgres + secrets. Foundation for the cohort dashboard in P2. No UI yet — API + DB + auth only.
|
||||
|
||||
### Phase 2 — Cohort Dashboard + Aggregation (planned)
|
||||
|
||||
**Branch:** `phase/02-cohort-dashboard` → merged to `milestone/v0.4-operator-tier`
|
||||
**Ship target:** `v0.1.8` (patch release, feature milestone type)
|
||||
**Status:** planned
|
||||
|
||||
**Goal:** Cohort aggregation pipeline (on-session-end hook + nightly reconciliation, k-anonymity ≥ 10, 7-day windows) + React cohort dashboard under `/operator/*` (served by same FastAPI, reuses v0.2 StaticFiles) + `/api/operator/*` endpoints (auth-gated). Dashboard shows anonymized practice/mastery/failure-pattern views with cells < 10 learners suppressed.
|
||||
|
||||
### Final Phase (P3) — Review + Ship (planned)
|
||||
|
||||
**Branch:** `phase/03-final-review-ship` → merged to `milestone/v0.4-operator-tier` → merged to `main`
|
||||
**Ship target:** final patch = v0.4 milestone release
|
||||
**Status:** planned
|
||||
|
||||
**Goal:** Multi-persona code review, project audit, milestone merge to main, milestone release.

Operator tier (REQ-DASH-01, REQ-AUTH-01, REQ-MT-01/02 + 4 NFRs) deferred to v0.4 per grill.
|
||||
|
||||
**Deliverables:**
|
||||

## Summary
|

|
||||
- **P1 REQ-IDs total:** 13 (7 functional + 6 NFR)
|
||||
- **Covered (all slices complete incl. SLICE-09):** 13 ✅
|
||||
- **Pending:** 0
|
||||
- **SLICE-08 sign-off:** all Wave 1–4 REQ-IDs (10/10) have covering tests in `tests/` or `scripts/`.
|
||||
- **SLICE-09 sign-off:** all 3 previously-pending VC REQ-IDs (REQ-MAST-03, REQ-NFR-VC-01, REQ-NFR-VC-02) now covered by 4 new test files (`test_vc_issuer.py`, `test_vc_integration.py`, `test_vc_interop.py`, `test_vc_key_rotation_drill.py`).
|
||||
- **Milestone ship (v0.1.4 → v0.1.5) gate:** UNBLOCKED — all 13 P1 REQ-IDs covered. P1 is green.
|
||||
|
||||
**P1 note (non-blocking, post-hoc):** The VC interop test (TASK-09-07) implements W3C VC 2.0 schema conformance + signature-format validation rather than verification against a live external W3C verifier process. This satisfies the *structure* of the grill Axis 3 MUST #1 (crypto claims are validated against the W3C VC 2.0 schema + Ed25519 format, not just self-consistency), but a live external-verifier interop run (e.g., `@digitalcredentials/vc` or `digitalbazaar/vc-verifier`) remains a recommended P2 follow-up for the staging environment where the full `PRAXIS_RUN_VC_INTEROP=1` validation runs.

|
||||
| Item | Status | Notes |
|
||||
|------|--------|-------|
|
||||
| All 20 REQ-IDs have implementation files | ✅ PASS | All 16 REQ-DEPLOY-* + 4 REQ-NFR-DEPLOY-* mapped to files |
|
||||
| All scripts executable (chmod +x) | ✅ PASS | 12 scripts in `scripts/proxmox/` + `scripts/install-service.sh` all `-rwxr-xr-x` |
|
||||
| All shell scripts pass `bash -n` | ✅ PASS | 13/13 scripts syntax-valid |
|
||||
| Dockerfile valid (stages, COPY ordering, CMD) | ✅ PASS | Multi-stage `node:22-slim` → `python:3.12-slim`; G-105 fix applied (copy pyproject.toml + README.md before `pip install .`); `CMD ["python", "-m", "server"]` |
|
||||
| docker-compose.yml valid YAML | ✅ PASS (after P0 fix) | `docker compose config --quiet` exits 0 after removing invalid `restart_policy` + making `env_file` optional |
|
||||
| .dockerignore excludes secrets | ✅ PASS | `.ciagent/` excluded; `.env`, `.env.secrets`, `.env.*` excluded with `!.env.example` exception; `scripts/`, `*.db`, `*.onnx` excluded |
|
||||
| .gitignore excludes .env.secrets, allows .env.example | ✅ PASS | `git check-ignore .ciagent/.env.secrets` → matches; `git check-ignore .env.example` → no match; `!.env.example` exception present (D-038) |
|
||||
### L1.1 — All PLAN.md-referenced files exist on disk
|
||||
|
||||
**Structural result: PASS** (1 P0 fixed: docker-compose.yml `restart_policy` invalid key)
|
||||
Checked: `rubrics/customer_service.yaml`, `server/mastery/*.py`, `server/scenarios/library.py`, `server/paths/*.py`, `paths/customer_service.yaml`, `scenarios/customer_service/*.yaml` (6 files), `scenarios/index.yaml`, `server/vc/*.py`, `db/migrations/0003_mastery.sql`, `scripts/test_mastery_e2e.py`, `scripts/test_real_llm_evidence.py`.
|
||||
|
||||
**Result: ✅ PASS** — all files present.
|
||||
|
||||
| Path | Status |
|
||||
|------|--------|
|
||||
| `rubrics/customer_service.yaml` | ✅ |

### L1.2 — All imports resolve
|
||||
|
||||
Command: `python3 -c "import server.mastery.rubric_loader; import server.mastery.evidence_extractor; import server.mastery.rubric_scorer; import server.mastery.mastery_score; import server.mastery.irt; import server.scenarios.library; import server.paths.engine; import server.paths.schema; import server.vc.issuer; import server.vc.issuer_keys; import server.vc.status_list; import server.vc.verification; print('ALL IMPORTS OK')"`
|
||||
|

**Result: ✅ PASS** — `ALL IMPORTS OK`.
|
||||
|
||||
### L1.3 — No stub implementations or TODO placeholders
|
||||
|
||||
Command: `grep -rn "TODO\|FIXME\|NotImplementedError\|pass #" server/mastery/ server/vc/ server/paths/ server/scenarios/library.py`
|
||||
|
||||
**Result: ✅ PASS** — zero matches across all P1 modules.
|
||||
|
||||
### L1.4 — All declared exports (`__all__`) resolve at runtime
|
||||
|
||||
Verified each module's `__all__` list against actual attributes via `hasattr()`:
|
||||
|
||||
**Result: ✅ PASS** — every `__all__` entry resolves on all 12 modules. Some `__all__` lists include re-imported symbols (e.g., `ValidationError`, `Path`, `CREDENTIAL_TIER`) — these are intentional re-exports for downstream consumers and all resolve correctly at runtime.
|

## 2. Behavioral Verification
|
||||
## Layer 2 — Behavioral Verification
|
||||
|
||||
| Item | Status | Notes |
|
||||
|------|--------|-------|
|
||||
| Bats tests: `bats scripts/proxmox/test/` | ✅ PASS | **121/121 tests pass** across 10 .bats files (api, e2e-deploy, firstboot-hook, health-check, lxc-clone, lxc-config, lxc-deploy, lxc-start, rollback, stage-snippet) |
|
||||
| Python tests: `pytest tests/ -x -q` | ✅ PASS | 77 passed, 9 skipped (live voice-service key tests — expected, no keys provisioned); v0.1 tests still pass after `db/store.py` + `db/migrate.py` PRAXIS_DB_PATH changes |
|
||||
| Dockerfile builds: `docker build -t praxis:verify .` | ✅ PASS (after P0 fix) | Build completes in ~105s; **required adding `fastapi` + `uvicorn` to pyproject.toml** (they were undeclared v0.1 deps — image failed to start without them) |
|
||||
| FastAPI StaticFiles mount doesn't break API routes | ✅ PASS | `GET /health` → `{"status":"ok",...}`; `GET /` → `<!doctype html>` (index.html); `GET /nonexistent` → 404; routes registered before mount (correct ordering) |
|
||||
| PRAXIS_DB_PATH env read works | ✅ PASS | `db/store.py:28` reads `os.environ.get("PRAXIS_DB_PATH", "praxis.db")`; `db/migrate.py:10` reads same; G-102 fix applied |
|
||||
| Image contains `client/dist/index.html` | ✅ PASS | `docker run --rm praxis:verify ls /app/client/dist/index.html` → exists |
|
||||
| Image does NOT contain `client/node_modules` | ✅ PASS | `ls /app/client/node_modules` → No such file |
|
||||
| Image does NOT contain `.ciagent/` (secrets) | ✅ PASS | `.ciagent/` excluded by .dockerignore |
|
||||
| `import server; import pipecat; import fastapi` in image | ✅ PASS (after P0 fix) | Prints `ok` |
|
||||
### L2.1 — Full test suite
|
||||
|
||||
**Behavioral result: PASS** (2 P0 fixed: pyproject.toml missing fastapi/uvicorn; docker-compose.yml invalid key)
|
||||
Command: `python3 -m pytest -q`
|
||||
|
||||
**Result: ✅ PASS** — **238 passed, 10 skipped, 1 warning** (103.65s). Matches the expected 238/10 baseline.
|
||||
|
||||
Skips are: 4 live voice-service tests (DEEPGRAM/CARTESIA/OLLAMA API keys not provisioned — expected in CI), 1 staging-gated VC interop full-validation test (`PRAXIS_RUN_VC_INTEROP=1` not set), and 5 other staging-gated tests. All skips are expected and documented.
|
||||
|
||||
### L2.2 — E2E mastery smoke
|
||||
|
||||
Command: `python3 scripts/test_mastery_e2e.py`
|
||||
|
||||
**Result: ✅ PASS** —
|
||||
- `PASS path score 4.0 >= 3.5`
|
||||
- `PASS progress advanced week-by-week`
|
||||
- `PASS 3 gate events recorded with parsable JSON evidence`
|
||||
- `RESULT: PASS`
|
||||
|
||||
### L2.3 — Real-LLM evidence smoke
|
||||
|
||||
Command: `python3 scripts/test_real_llm_evidence.py`
|
||||
|
||||
**Result: ✅ SKIP (clean)** — `SKIP (set PRAXIS_RUN_REAL_LLM_TESTS=1 to run)`. Cleanly gated, no crash, no false failure. Staging-only test per grill Axis 7 FIX #1.
|
||||
|
||||
### L2.4 — REQ-ID coverage (all 13 v0.3 REQ-IDs have covering tests)
|
||||
|
||||
Verified all 15 covering test files exist on disk: `test_rubric_schema.py`, `test_rubric_scoring.py`, `test_evidence_extractor_integration.py`, `test_mastery_integration.py`, `test_irt.py`, `test_irt_selection_integration.py`, `test_scenario_library.py`, `test_scenario_library_content.py`, `test_path_engine.py`, `test_gate_audit_log.py`, `test_vc_issuer.py`, `test_vc_integration.py`, `test_vc_interop.py`, `test_vc_key_rotation_drill.py`, `test_learner_ability_db.py`.
|
||||
|
||||
Ran the VC subset explicitly: `pytest tests/test_vc_issuer.py tests/test_vc_integration.py tests/test_vc_key_rotation_drill.py -q` → 19/19 passed. Also ran `PRAXIS_RUN_VC_INTEROP=1 pytest tests/test_vc_interop.py -q` → 5/5 passed.
|
||||
|
||||
**Result: ✅ PASS** — all 13 REQ-IDs covered. Updated `VERIFY-P1.md` matrix to mark REQ-MAST-03, REQ-NFR-VC-01, REQ-NFR-VC-02 as covered (SLICE-09 complete).
|
||||
|
||||
### L2.5 — Grill MUST conditions (GRILL-v0.3.md — 4 MUST)
|
||||
|
||||
| # | Grill condition | Verified | Evidence |
|
||||
|---|----------------|----------|----------|
|
||||
| Axis 2 | Split milestone — operator tier deferred to v0.4 | ✅ YES | `PLAN.md:38-46` enumerates 8 deferred REQ-IDs; v0.3 REQ-IDs reduced to 13 (was 20). No operator-tier code in P1 (no `server/auth/`, no `server/operator/`, no `db/pg_*`). |
|
||||
| Axis 3 #1 | VC interop test exists | ✅ YES | `tests/test_vc_interop.py` exists (153 LOC). Schema conformance + JCS + Ed25519 sig-format validated. **P1 note:** the `test_full_w3c_vc_interop_validation` is a staging-gated extended self-check, not a live external-verifier run — see Layer 4 / P1-3 below. |
|
||||
| Axis 3 #2 | Key-rotation drill test exists | ✅ YES | `tests/test_vc_key_rotation_drill.py` exists, 5/5 passed. Issues N with key A, rotates to B, issues M, verifies all N+M, revokes one each. |
|
||||
| Axis 4 #1 | `credentialTier: "formative"` in VC payload | ✅ YES | `server/vc/issuer.py:34` `CREDENTIAL_TIER = "formative"`; set in payload at `issuer.py:77` and `issuer.py:89`. |
|
||||
| Axis 4 #3 | `scoring_inconclusive` fallback (no silent fail-to-zero) | ✅ YES | `server/mastery/evidence_extractor.py:37` (`scoring_inconclusive: bool = False`); returned at `evidence_extractor.py:198` after max re-extraction attempts. `session_recorder.py:185-192` short-circuits and surfaces `retry_advised: True` when inconclusive — no score recorded, no gate event, no penalty. |
|
||||
| Axis 8 | VC issuance wired to gate-open (not orphaned) | ✅ YES | `server/session_recorder.py:276-293` — `path_complete = gate_open and new_week >= 6`; on True, lazy-imports `server.vc.issuer.issue_credential` and calls it with learner_id, path, scenarios_passed, rubric_score, completed_weeks, evidence. ImportError is swallowed (SLICE-09-independent P1 ship). |
|
||||
|
||||
**Grill MUST summary: 4/4 MUST conditions satisfied.** (Axis 4 #2 — Secure cookie + TLS — is N/A for v0.3: operator auth was deferred to v0.4 per Axis 2, so there is no operator surface in v0.3 and no cookie issue.)
|
||||
|
||||
### L2.6 — Grill FIX conditions (5 — non-blocking, tracked)
|
||||
|
||||
| # | Grill FIX | Status |
|
||||
|---|-----------|--------|
|
||||
| Axis 1 | Re-task SLICE-12/13 (operator tier) | N/A — operator tier deferred to v0.4; SLICE-12/13 do not exist in P1. Moot. |
|
||||
| Axis 5 | Wire P1→P2 VC-issuance trigger | ✅ Resolved — VC is in P1 (SLICE-09), wired at `session_recorder.py:276-293`. |
|
||||
| Axis 6 | Postgres-failure semantics | Deferred to v0.4 (operator tier). Moot for v0.3. |
|
||||
| Axis 7 | Real-LLM smoke test | ✅ Done — `scripts/test_real_llm_evidence.py` exists, staging-gated via `PRAXIS_RUN_REAL_LLM_TESTS=1`. |
|
||||
| Axis 9 | De-escalation weight clarification | ✅ Static in v0.3 — `rubrics/customer_service.yaml` ships static weights (de-escalation 0.20); dynamic re-weighting is a future feature per `PLAN.md:23`. |

## 3. Security Verification
|
||||
## Layer 3 — Security Verification (STRIDE)
|
||||
|
||||
| Item | Status | Notes |
|
||||
|------|--------|-------|
|
||||
| No secrets in committed files | ✅ PASS | `grep` for hardcoded API keys/tokens in new files → none found; all use `${VAR}` expansion or empty defaults |
|
||||
| .dockerignore excludes `.ciagent/.env*` | ✅ PASS | `.ciagent/` directory excluded; secrets never in build context |
|
||||
| .gitignore excludes `.env.secrets` | ✅ PASS | `git check-ignore .ciagent/.env.secrets` → matches |
|
||||
| stage-snippet.sh bakes GITEA_TOKEN at runtime (G-101) | ✅ PASS | `sed -i "s\|\${GITEA_TOKEN}\|${GITEA_TOKEN}\|g"` substitutes the placeholder; token is NOT committed to repo, only baked into the snippet at staging time (stored in Proxmox snippet storage, not git) |
|
||||
| docker-compose.yml uses env_file (not hardcoded secrets) | ✅ PASS | `env_file: /etc/praxis/server.env` (written by install-service.sh from lxc.environment); no secret values in compose file |
|
||||
| install-service.sh writes env file with mode 0640 | ✅ PASS | `chmod 0640 "$ENV_FILE"` + `chown root:praxis` (root:praxis only) |
|
||||
| firstboot-hook.sh GITEA_TOKEN from baked snippet (not env) | ✅ PASS | Hook uses `${GITEA_TOKEN}` which is baked by stage-snippet.sh; comment documents the G-101 fix |
|
||||
Scope: VC issuer (`server/vc/issuer.py`, `issuer_keys.py`, `status_list.py`) + verification endpoint (`server/vc/verification.py`) — the highest-risk surface.
|
||||
|
||||
**Security result: PASS** (no issues)
|
||||
| Threat | Vector | Mitigation | Verdict |
|
||||
|--------|--------|------------|---------|
|
||||
| **Spoofing** | Can an attacker forge a VC? | Ed25519 signature over JCS-canonicalized payload (`issuer.py:128-138`). Private key encrypted at rest with `nacl.secret.SecretBox` keyed by `PRAXIS_VC_ISSUER_KEY` env (`issuer_keys.py:53-57`). Verification fetches public key by `key_id` from `verificationMethod` URL (`verification.py:39`). | ✅ Secure — forging a VC requires the encrypted private key + the `PRAXIS_VC_ISSUER_KEY` root key. |
|
||||
| **Tampering** | Can a payload be modified post-issuance? | `verify_proof` (`issuer.py:141-159`) re-canonicalizes the unsecured doc + proof options and verifies the signature. Any byte flip invalidates the signature. Tested: `test_vc_issuer.py` tamper detection + `test_vc_integration.py` tamper→verify fails. | ✅ Secure — tamper-evident by construction. |
|
||||
| **Repudiation** | Can issuance be denied? | `mastery_gate_events` SQLite table (`db/migrations/0003_mastery.sql:28-41`) records every gate-open event with `scenarios_passed_json` + `rubric_scores_json` + `gate_opened_at`. `session_recorder.py:263-271` records the event on every scored session. Tested: `test_gate_audit_log.py` queries by learner/path/date range. | ✅ Secure — issuance is auditable. |
|
||||
| **Info Disclosure** | Does `/vc/verify` leak PII? | `verification.py:53-73` returns only: `{valid, status, issuer, credential{id,type,validFrom,validUntil}, mastery{skill,level,path,rubricScore,scenariosPassed,completedWeeks}, credentialTier, verifiedAt}`. No learner email/name/phone/address. `credentialSubject.id` is `urn:uuid:<learner_ref>` (opaque). | ✅ Secure — no PII beyond what the credential itself asserts (which is the learner's own mastery claim). |
|
||||
| **DoS** | Can `/vc/verify` be flooded? | Endpoint is public + unauthenticated (D-043, by design — third-party verifiers must reach it). No rate limiting in v0.3. | ⚠️ **P1 risk** — acceptable for pilot (single-deploy, low traffic). Flag for v0.4: add slowapi rate-limit on `/vc/verify/*` (e.g., 60 req/min/IP). |
|
||||
| **Elevation** | Can a learner issue themselves a credential? | `issue_credential` (`issuer.py:170-203`) requires `PraxisStore` + the active signing key (decrypted from `issuer_keys` table via `PRAXIS_VC_ISSUER_KEY`). Learner-facing code never calls `issue_credential` directly — only `session_recorder.run_mastery_flow` calls it after gate-open. The signing key is not learner-accessible. | ✅ Secure — issuance is server-side only, gated by the mastery flow. |
|
||||
|
||||
**STRIDE summary:** 5/6 threats fully mitigated. 1 P1 risk (DoS on public verify endpoint) — acceptable for pilot, flagged for v0.4 hardening.

## 4. Quality Verification
|
||||
## Layer 4 — Quality Verification (multi-persona review)
|
||||
|
||||
| Item | Status | Notes |
|
||||
|------|--------|-------|
|
||||
| Shell scripts follow coreci patterns (set -eu, pve_env, SCRIPT_DIR) | ✅ PASS | All scripts: `set -eu`, `SCRIPT_DIR="$(cd "$(dirname "$0")" && pwd)"`, `pve_env` validation, `. api.sh` sourcing |
|
||||
| No remaining "coreci" references in praxis scripts (except origin comments) | ✅ PASS (after P0 fix) | timing.sh was using `coreci_deploy_timing_*` metric names — **fixed to `praxis_deploy_timing_*`**; remaining "coreci" refs are: origin comments ("Adapted from coreci"), Gitea org name (`GITEA_ORG="coreci"` — the repo owner), D-026 secret path (`~/coreci/.ciagent/.env.secrets`) — all correct |
|
||||
| Bats tests cover all scripts (10 files, not 9 — G-106) | ⚠️ NOTE | 10 .bats files exist (121 tests), but **3 PLAN-specified test files are missing**: `timing.bats` (TASK-09-07), `idempotency.bats` (TASK-09-08), `docker-build.bats` (TASK-09-10). Idempotency IS covered in lxc-deploy.bats (16 tests), timing is exercised via lxc-deploy.bats, and docker-build is verified manually here. Coverage is adequate but doesn't match the PLAN's file list. |
|
||||
| Health-check timeout is 600s (G-104, not 300s or 180s) | ✅ PASS | `health-check.sh:29` — `timeout_s="${PRAXIS_HEALTH_TIMEOUT:-600}"`; praxis.service `TimeoutStartSec=600`; .env.example documents `PRAXIS_HEALTH_TIMEOUT=600` |
|
||||
| Dockerfile copies pyproject.toml before source (G-105) | ✅ PASS | `COPY pyproject.toml README.md ./` → `RUN pip install .` → `COPY server/ scenarios/ db/` (correct ordering) |
|
||||
### Q1 — `server/vc/issuer.py` (security-engineer territory)
|
||||
|
||||
**Quality result: PASS with notes** (1 P0 fixed: timing.sh metric names; 1 note: missing 3 bats files but coverage is adequate via other files)
|
||||
- **Correctness (JCS + Ed25519):** JCS canonicalization via `canonicaljson.encode_canonical_json` (`issuer.py:103-104`) — deterministic, RFC 8785-aligned. Data Integrity proof follows the eddsa-jcs-2022 pattern: `proof_options` canonicalized separately, `hash_data = SHA256(canonical_proof) || SHA256(canonical_doc)`, signed with Ed25519 (`issuer.py:128-138`). `verify_proof` reconstructs the same hash and verifies (`issuer.py:141-159`). Round-trip verified by 19 passing tests.
|
||||
- **Security (key handling):** Signing keys never serialized to disk in plaintext — encrypted via `nacl.secret.SecretBox` in `issuer_keys.py`. `issue_credential` lazily fetches the active key via `get_active_signing_key`. Key rotation (`rotate_key`) marks old keys `superseded`, not deleted — old VCs still verify.
|
||||
- **Quality:** Clean, typed, documented. `CREDENTIAL_TIER = "formative"` is a module-level constant (good — single source of truth).
|
||||
- **P1 flag (P1-2):** `issuer_keys.py:25-31` `_load_root_key()` silently falls back to `nacl.utils.random(...)` if `PRAXIS_VC_ISSUER_KEY` is unset. This means: in a deploy where the env var is missing, the server will *appear* to work but every restart generates a new random root key → previously-issued credentials' private keys become undecryptable → `get_active_signing_key` raises on the *next* issuance attempt (the old key's ciphertext won't decrypt). The *old VCs still verify* (public key is stored unencrypted), but new issuance silently breaks. This is a **P1 operational footgun**, not a P0 (no data loss, no security hole — just a confusing failure mode). Recommended fix for v0.4: fail fast at startup if `PRAXIS_VC_ISSUER_KEY` is unset (raise `RuntimeError` instead of silent random fallback), or persist the root key to a secrets manager on first init.
|
||||
|
||||
### Q2 — `server/mastery/evidence_extractor.py` (backend-engineer territory)
|
||||
|
||||
- **Correctness (fuzzy-match):** `_fuzzy_contains` (`evidence_extractor.py:52-72`) uses `difflib.SequenceMatcher` with a sliding window (window = `qlen + max(20, qlen//4)`, step = `max(1, qlen//4)`) and a 0.85 ratio threshold. Handles both substring-exact and near-verbatim (accent/noise tolerance). Re-extraction loop (`evidence_extractor.py:149-201`) appends rejected quotes to the next prompt's correction message — good feedback loop.
|
||||
- **Security (LLM injection):** The transcript is injected into the user message verbatim (`evidence_extractor.py:86`), so a malicious *learner* could attempt prompt injection in their spoken turns (e.g., "ignore previous instructions, return..."). Mitigations: (a) the system prompt is fixed and authoritative, (b) output is JSON-schema-validated (`_parse_evidence_json` rejects non-list, unknown `criterion_id`, schema-invalid items), (c) quotes are fuzzy-matched against the transcript — an injected "quote" that isn't in the transcript is rejected. The highest-impact injection (faking evidence to boost a score) is blocked by the fuzzy-match gate.
|
||||
- **Quality:** `ExtractionResult.scoring_inconclusive` path is well-documented and correctly short-circuits in `session_recorder.py:185-192`. No silent fail-to-zero (grill Axis 4 #3 satisfied).
|
||||
- **P2 note (non-blocking):** Consider adding a max-transcript-length guard (truncation or chunking) — a 30-minute session transcript could exceed the model's context window. Not a v0.3 blocker (pilot sessions are short).
|
||||
|
||||
### Q3 — `server/mastery/mastery_score.py` (backend-engineer territory)
|
||||
|
||||
- **Correctness (gate logic):** `compute_scenario_score` (`mastery_score.py:33-68`) — weighted mean with conjunctive floor (every criterion ≥2, mean ≥3.0 to pass). `check_gate` (`mastery_score.py:78-86`) — ≥3 distinct passed AND path_score ≥3.5 (D-032). Constants are module-level (`_GATE_REQUIRED_DISTINCT = 3`, `_GATE_REQUIRED_SCORE = 3.5`). Floor violations produce a structured `fail_reason` (good for debugging).
|
||||
- **Quality (determinism):** Pure function — no I/O, no LLM, no randomness. `round(total, 6)` ensures stable float comparison. Same input → same output, verified by `test_mastery_integration.py::test_mastery_flow_is_deterministic`.
|
||||
- **P1 flag (P1-4):** `compute_path_score` takes `passing_scenario_scores` but `session_recorder.py:209-211` only passes `[scenario_score] if scenario_score.passed else []` — i.e., the current session's score only, not the cumulative mean over all passing sessions. This means `path_score` is the *current session's* score, not the mean over all passing scenarios to date. This appears to be a known simplification (comment at `session_recorder.py:212-213`: "If prior passing scenario scores are tracked elsewhere, they'd be folded in here"). The gate still works because `distinct_passed_count` correctly accumulates in `scenarios_passed`. This is a **P1 semantic simplification** — flag for v0.4: fold in prior passing scores from `mastery_progress` for a true path mean. Not a P0 (the gate's distinct-count condition is the primary gate; the score threshold is secondary and the current-session score is a reasonable proxy).
|
||||
|
||||
### Q4 — `server/session_recorder.py` (backend-engineer territory)
|
||||
|
||||
- **Correctness (mastery flow wiring):** `run_mastery_flow` (`session_recorder.py:154-311`) correctly sequences: extract → score → IRT update → progress upsert → gate event record → VC issuance. The `scoring_inconclusive` short-circuit (`session_recorder.py:185-192`) correctly skips all downstream steps and surfaces `retry_advised: True`.
|
||||
- **Quality (error handling):** The VC issuance block (`session_recorder.py:278-293`) wraps `issue_credential` in `try/except ImportError` (SLICE-09-independent ship) + `except Exception` (logs the failure, doesn't crash the mastery flow). The outer `run_mastery_flow` call at `session_recorder.py:150-152` wraps the whole flow in `try/except Exception` with `log.exception` — a mastery-flow failure never crashes the session end. Good isolation.
|
||||
- **P1 flag (P1-3):** The VC interop test (`tests/test_vc_interop.py`) — while it does validate W3C VC 2.0 schema conformance, JCS canonical JSON, Ed25519 signature format (64 bytes), and all required fields — does *not* invoke a live external W3C verifier (e.g., `@digitalcredentials/vc` JS verifier or `digitalbazaar/vc-verifier`). The `test_full_w3c_vc_interop_validation` test (staging-gated) is an extended self-check, not an external-verifier round-trip. The grill Axis 3 MUST #1 explicitly called for verification against an *external* verifier ("Round-trip self-verification is insufficient for cryptographic claims"). The structural conformance checks are strong evidence of W3C compliance, but a live external-verifier run in staging remains the grill's strictest bar. **P1 flag for post-hoc review**: schedule a staging run with `@digitalcredentials/vc` (or equivalent) before the v0.3 milestone ship (v0.1.5). This does not block P1 sign-off — the schema + crypto-format validation is sufficient for the v0.1.4 patch ship.

## 5. Must-Have Verification (MH-01..MH-28)
|
||||
## REQ-ID Coverage Table (all 13 v0.3 REQ-IDs)
|
||||
|
||||
| MH-ID | Requirement | Status | Evidence |
|
||||
|-------|-------------|--------|----------|
|
||||
| MH-01 | `docker build -t praxis:test .` succeeds | ✅ PASS | Build completes (~105s) after fastapi/uvicorn added to pyproject.toml |
|
||||
| MH-02 | `docker compose config` parses without error | ✅ PASS (fixed) | Was failing due to invalid `restart_policy` key; fixed → exits 0 |
|
||||
| MH-03 | `docker run --rm praxis:test python -c "import server, pipecat"` | ✅ PASS (fixed) | Prints `ok` after fastapi added to pyproject.toml |
|
||||
| MH-04 | Image contains `client/dist/index.html` | ✅ PASS | Verified via `docker run --rm praxis:verify ls /app/client/dist/index.html` |
|
||||
| MH-05 | `.dockerignore` excludes node_modules, .git, client/dist, .ciagent/.env* | ✅ PASS | All patterns present in .dockerignore |
|
||||
| MH-06 | SQLite persists across `docker compose restart` via named volume | ✅ PASS (design) | `praxis-data` volume mounted at `/app/data`; `PRAXIS_DB_PATH=/app/data/praxis.db` set in compose + env; `db/store.py` + `db/migrate.py` read PRAXIS_DB_PATH (G-102 fix). Live restart test not run (no Docker daemon persistence in verify env), but the wiring is correct. |
|
||||
| MH-07 | `GET /health` returns JSON `{"status":"ok",...}` | ✅ PASS | Verified via `curl http://localhost:18789/health` → `{"status":"ok","version":"0.1.0","keys":{...},"tts":"cartesia"}` |
|
||||
| MH-08 | `GET /` returns index.html when client/dist exists | ✅ PASS | `curl http://localhost:18789/` → `<!doctype html><html lang="en">` |
|
||||
| MH-09 | `GET /nonexistent` returns 404 | ✅ PASS | `curl -s -o /dev/null -w "%{http_code}"` → `404` |
|
||||
| MH-10 | `pytest tests/` passes (no regression) | ✅ PASS | 77 passed, 9 skipped (live-key tests) |
|
||||
| MH-11 | All scripts pass `sh -n` and `shellcheck` | ✅ PASS | 13/13 syntax-valid; shellcheck clean (only SC1090 non-constant-source warning on e2e-deploy.sh, expected) |
|
||||
| MH-12 | api.sh, ct-exists.sh, lxc-start.sh byte-identical to coreci | ⚠️ PARTIAL | api.sh: byte-identical ✓; lxc-start.sh: differs only in header comment (line 2 "CoreCI"→"Praxis") — functionally identical; ct-exists.sh: differs in comments + path reference (coreci has it in `proxy/ct-exists.sh`, praxis at top level) — functionally identical. Header-comment-only diffs are acceptable adaptations. |
|
||||
| MH-13 | lxc-clone.sh uses hostname=praxis, rootfs=:16, memory=4096 | ✅ PASS | `hostname=${PRAXIS_HOSTNAME:-praxis}`, `rootfs=${storage}:16`, `memory=${PROXMOX_MEMORY_MB:-4096}`, `features=nesting=1` |
|
||||
| MH-14 | lxc-config.sh emits praxis-firstboot.sh hookscript + praxis env vars | ✅ PASS (fixed) | `hookscript_volid="${storage}:snippets/praxis-firstboot.sh"`; emits all praxis lxc.environment vars (PRAXIS_HOST, PRAXIS_PORT, PRAXIS_DB_PATH, PRAXIS_SCENARIOS_DIR, GITEA_TOKEN, DEEPGRAM/CARTESIA/OLLAMA keys + config). **Fixed**: added missing PRAXIS_HOST + PRAXIS_SCENARIOS_DIR; aligned defaults with .env.example + docker-compose.yml |
|
||||
| MH-15 | health-check.sh polls /health:8789 with 600s timeout | ✅ PASS | `health_url="http://${ip}:${http_port}/health"`; `http_port=${PRAXIS_PORT:-8789}`; `timeout_s=${PRAXIS_HEALTH_TIMEOUT:-600}` (G-104 fix applied) |
|
||||
| MH-16 | firstboot-hook.sh installs Docker + clones repo + runs install-service.sh | ✅ PASS (fixed) | Step 1: apt install docker.io docker-compose-v2 git curl; Step 2: git clone; Step 3: sh scripts/install-service.sh. **Fixed**: idempotency check was referencing non-existent `/usr/local/bin/praxis-deploy` (coreci artifact) → changed to `[ -d /opt/praxis/.git ] && systemctl is-active --quiet praxis` |
|
||||
| MH-17 | lxc-deploy.sh orchestrates clone→config→start→health with rollback trap + idempotency | ✅ PASS | EXIT trap calls rollback.sh on failure; idempotency check (ct_exists + ct_running + health); --recreate/--reconfigure flags; timing wrappers |
|
||||
| MH-18 | lxc-deploy.sh has NO proxy/PROXY_VMID/BACKEND_DOMAIN steps | ✅ PASS | 0 matches for PROXY_VMID/BACKEND_DOMAIN/backend-add/smoke-test |
|
||||
| MH-19 | praxis.service: ExecStart=docker compose up + ExecStartPre=docker compose build + Restart=on-failure + TimeoutStartSec | ✅ PASS (fixed) | ExecStartPre=/usr/bin/docker compose build; ExecStart=/usr/bin/docker compose up; Restart=on-failure; TimeoutStartSec=600 (G-104). **Fixed**: User=root → User=praxis (MH-21 alignment). Unit is written inline via heredoc in install-service.sh (not a separate file, but functionally equivalent). |
|
||||
| MH-20 | praxis.service has NO Docker-incompatible hardening | ✅ PASS | No ProtectSystem/PrivateDevices/RestrictNamespaces/NoNewPrivileges/MemoryDenyWriteExecute; comment documents the decision |
|
||||
| MH-21 | install-service.sh creates praxis user in docker group + writes env file + installs unit | ✅ PASS (fixed) | useradd + usermod -aG docker; writes /etc/praxis/server.env (0640, root:praxis); installs systemd unit; **Fixed**: User=praxis in unit (was User=root) |
|
||||
| MH-22 | config.json secrets.scopes has release/proxmox/voice with correct env vars | ✅ PASS (fixed) | All 3 scopes present; **Fixed**: removed PROXMOX_LXC_VMID from proxmox scope (D-037 — it's `auto`, not a secret) |
|
||||
| MH-23 | lxc-deploy.sh sources ~/coreci/.ciagent/.env.secrets + praxis .ciagent/.env.secrets | ✅ PASS (fixed) | **Fixed**: added secret-sourcing block to lxc-deploy.sh (was only in e2e-deploy.sh wrapper). Sources both files with graceful warnings if absent; pve_env validates after. |
|
||||
| MH-24 | .env.example documents all PROXMOX_* + deploy vars (no actual secrets) | ✅ PASS | Deployment section documents PROXMOX_API_URL/TOKEN/NODE/STORAGE/TEMPLATE_VOLID/LXC_VMID/TLS_SKIP_VERIFY/MEMORY_MB + PRAXIS_HEALTH_URL/PORT/TIMEOUT + PRAXIS_CLIENT_DIST; all commented out or empty; D-026 source-from-coreci documented |
|
||||
| MH-25 | git check-ignore: .ciagent/.env.secrets matches; .env.example does not | ✅ PASS | Verified both |
|
||||
| MH-26 | `make test-proxmox-scripts` passes — 10 bats files | ⚠️ PARTIAL | 121 bats tests pass via `bats scripts/proxmox/test/`, but **no Makefile exists** (TASK-09-11 not implemented). `make test-proxmox-scripts` target unavailable. Tests pass when run directly via bats. |
|
||||
| MH-27 | e2e-deploy.bats passes against live Proxmox (or skips) | ✅ PASS | e2e-deploy.bats has `PRAXIS_E2E_LIVE=1` skip guard — skips by default (no live cluster in CI); 7 e2e tests present |
|
||||
| MH-28 | E2E deploy completes in < 5 min | ⏭️ DEFERRED | Requires live Proxmox cluster + secrets; not runnable in verify env. Wiring (timing wrappers, 600s timeout) is correct. |

|
||||
## 7. P0 Issues (Critical — FIXED)
|
||||
## P0 Fixes Applied
|
||||
|
||||
### P0-01: docker-compose.yml invalid `restart_policy` key (MH-02, REQ-DEPLOY-02)
|
||||
- **Symptom:** `docker compose config` failed with `services.praxis additional properties 'restart_policy' not allowed`
|
||||
- **Root cause:** `restart_policy` is only valid for `docker stack deploy` (Swarm), not `docker compose`. A duplicate `restart: on-failure` was already present on line 9.
|
||||
- **Fix:** Removed the `restart_policy` block; changed `restart: on-failure` → `restart: unless-stopped` (per PLAN spec); changed `env_file` to `required: false` syntax so `docker compose config` validates without the file present (install-service.sh always creates it before `up` in production).
|
||||
- **Status:** ✅ FIXED
|
||||
**None.** No P0 (critical bug) fixes were required. All 238 tests pass, all imports resolve, no stubs/TODOs, all 13 REQ-IDs covered, all 4 grill MUST conditions satisfied.
|
||||
|
||||
### P0-02: pyproject.toml missing `fastapi` + `uvicorn` dependencies (MH-01, MH-03, MH-07, REQ-DEPLOY-01, REQ-DEPLOY-13)
|
||||
- **Symptom:** `docker run praxis:verify` failed with `ModuleNotFoundError: No module named 'fastapi'`; server couldn't start.
|
||||
- **Root cause:** `server/__main__.py` imports `fastapi` and `uvicorn`, but neither was declared in `pyproject.toml` `[project.dependencies]`. They were installed in the dev environment (v0.1) but not declared — the Dockerfile exposed the gap because the image only installs `pip install .` deps.
|
||||
- **Fix:** Added `"fastapi>=0.110"` and `"uvicorn>=0.30"` to `pyproject.toml` dependencies. Rebuilt image → server starts, `/health` and `/` both work.
|
||||
- **Status:** ✅ FIXED
|
||||
## P1+ Flags (post-hoc review — non-blocking for v0.1.4 ship)
|
||||
|
||||
### P0-03: timing.sh still used `coreci_deploy_timing_*` metric names (REQ-DEPLOY-08, TASK-03-07)
|
||||
- **Symptom:** timing.sh emitted `{"event":"deploy_timing",...}` and Prometheus metric `coreci_deploy_timing_seconds` — not the praxis-prefixed names required by TASK-03-07.
|
||||
- **Root cause:** timing.sh was copied verbatim from coreci with a note saying "rename in a follow-up if desired" — but TASK-03-07 requires the rename as part of the deliverable.
|
||||
- **Fix:** Changed event → `praxis_deploy_timing`, metric → `praxis_deploy_timing_seconds`, textfile path → `praxis_deploy_timing_<stage>.prom`. Verified via sourcing + textfile collector test.
|
||||
- **Status:** ✅ FIXED
|
||||
|
||||
### P0-04: firstboot-hook.sh idempotency check references non-existent binary (REQ-DEPLOY-06, REQ-NFR-DEPLOY-01)
|
||||
- **Symptom:** The idempotency check `[ -x /usr/local/bin/praxis-deploy ] && systemctl is-active --quiet praxis` would NEVER short-circuit in production because praxis never creates `/usr/local/bin/praxis-deploy` (that's a coreci Go binary path). Every CT restart that triggers the post-start hook would re-run the full install (apt install docker, git clone, install-service).
|
||||
- **Root cause:** The check was copied from coreci's firstboot-hook (which installs a binary to `/usr/local/bin/`) without adapting for praxis's docker-compose-based deployment.
|
||||
- **Fix:** Changed check to `[ -d /opt/praxis/.git ] && systemctl is-active --quiet praxis` — verifies the repo is cloned AND the service is active.
|
||||
- **Note:** The bats test for this passed before the fix because the mock `pct` returns exit 0 regardless of the actual command body — the test validates the hook's behavior given a successful idempotency probe, not the probe's actual logic. This is a test-design limitation (mocking `pct exec` at the process level can't validate the `sh -c` body).
|
||||
- **Status:** ✅ FIXED
|
||||
| ID | Flag | Severity | Location | Recommended action |
|
||||
|----|------|----------|----------|--------------------|
|
||||
| **P1-1** | `/vc/verify` is public + unauthenticated with no rate limiting → DoS vector | P1 | `server/vc/verification.py` | v0.4: add slowapi rate-limit (60 req/min/IP) on `/vc/verify/*`. Acceptable for pilot (single-deploy, low traffic). |
|
||||
| **P1-2** | `_load_root_key()` silently falls back to a random key when `PRAXIS_VC_ISSUER_KEY` is unset → cross-restart issuance breaks silently (old VCs still verify, but new issuance fails on next restart) | P1 | `server/vc/issuer_keys.py:25-31` | v0.4: fail fast at startup if env var unset (raise `RuntimeError`), or persist root key to a secrets manager on first init. Operational footgun, not a security hole. |
|
||||
| **P1-3** | VC interop test (`test_vc_interop.py`) validates W3C schema + crypto format but does not invoke a live external W3C verifier (grill Axis 3 MUST #1's strictest bar) | P1 | `tests/test_vc_interop.py:128-153` | Before v0.3 milestone ship (v0.1.5): schedule a staging run with `@digitalcredentials/vc` or `digitalbazaar/vc-verifier` to clear the grill's strictest interop bar. Schema + format validation is sufficient for v0.1.4 patch ship. |
|
||||
| **P1-4** | `compute_path_score` in `session_recorder.py:209-211` uses only the current session's score, not the cumulative mean over all passing sessions | P1 | `server/session_recorder.py:209-211` | v0.4: fold in prior passing scores from `mastery_progress.scenarios_passed_json` for a true path mean. Gate still works (distinct-count is primary; score threshold is secondary). |

| **P2-1** | No max-transcript-length guard in evidence extraction → long sessions could exceed the model context window | P2 | `server/mastery/evidence_extractor.py:75-93` | Future: truncation or chunking for >30-min sessions. Not a v0.3 blocker (pilot sessions are short). |

## 8. P1+ Issues (Non-critical — flagged for post-hoc review)
|
||||
## Final Verdict: **APPROVE_WITH_NOTES**
|
||||
|
||||
### P1-01: Missing `praxis.service` standalone file (REQ-DEPLOY-11)
|
||||
- The PLAN specifies `scripts/proxmox/praxis.service` as a file, but the unit is written inline via heredoc in `install-service.sh` (line 74). Functionally equivalent (the unit content is identical), but doesn't match the PLAN's file structure. No fix applied — the inline approach works and avoids a path-resolution issue (install-service.sh would need to locate the service file relative to itself).
|
||||
- **Recommendation:** Accept the inline approach; update PLAN if needed.
|
||||
P1 (Mastery Core + VC Issuance) is verified:
|
||||
|
||||
### P1-02: Missing 3 bats test files (MH-26, TASK-09-07/08/10)
|
||||
- `timing.bats`, `idempotency.bats`, `docker-build.bats` are not present. However:
|
||||
- Idempotency IS tested in `lxc-deploy.bats` (16 tests cover --recreate/--reconfigure/healthy-skip/no-flag-error)
|
||||
- Timing is exercised via `lxc-deploy.bats` (timing_start/timing_end wrappers called)
|
||||
- Docker-build is verified manually in this verification (MH-01/03/04 pass)
|
||||
- **Recommendation:** Add the 3 missing bats files for explicit coverage in a follow-up; current coverage is adequate for ship.
|
||||
- ✅ **Layer 1 (Structural):** all 9 slices' files present, imports resolve, no stubs, `__all__` exports valid.
|
||||
- ✅ **Layer 2 (Behavioral):** 238 passed / 10 skipped, E2E smoke PASS, real-LLM smoke skips cleanly, 13/13 REQ-IDs covered, 4/4 grill MUST conditions satisfied.
|
||||
- ✅ **Layer 3 (Security):** 5/6 STRIDE threats mitigated; 1 P1 DoS risk on public verify endpoint (acceptable for pilot, flagged for v0.4).
|
||||
- ✅ **Layer 4 (Quality):** 4 highest-risk files reviewed — clean, deterministic, well-documented. 4 P1 flags + 1 P2 note for post-hoc review.
|
||||
|
||||
### P1-03: Missing `Makefile` (MH-26, TASK-09-11)
|
||||
- No `Makefile` with `test-proxmox-scripts` target. Tests run via `bats scripts/proxmox/test/` directly.
|
||||
- **Recommendation:** Add a minimal Makefile in a follow-up.
|
||||
**No P0 fixes required.** P1 is green and shippable as `v0.1.4`. The 5 P1/P2 flags are non-blocking and tracked for v0.4 / the v0.1.5 milestone ship. The milestone ship gate (v0.1.5) is **unblocked** — all 13 REQ-IDs covered.
|
||||
|
||||
### P1-04: Missing `e2e-smoke.sh` (TASK-10-02)
|
||||
- The standalone smoke script isn't present, but `e2e-deploy.sh` covers the same checks (/health JSON, / HTML, keys field).
|
||||
- **Recommendation:** Accept e2e-deploy.sh as the smoke verification; add e2e-smoke.sh if a manual post-deploy smoke tool is wanted.
|
||||
|
||||
### P1-05: lxc-config.sh defaults were inconsistent with .env.example + docker-compose.yml (FIXED)
|
||||
- OLLAMA_BASE_URL defaulted to `http://ollama.cloudinit.dev:11434` (vs `https://ollama.com/v1`); DEEPGRAM_LANGUAGE `en-US` (vs `en`); DEEPGRAM_REGION `us-east-1` (vs `na`); PRAXIS_TTS `deepgram` (vs `cartesia`); CARTESIA_VOICE_ID empty (vs the shared voice ID).
|
||||
- **Status:** ✅ FIXED — aligned all defaults with .env.example + docker-compose.yml + install-service.sh.
|
||||
|
||||
### P1-06: e2e-deploy.sh always passes `--insecure` to curl (line 80)
|
||||
- `curl -sS --insecure ${PROXMOX_TLS_SKIP_VERIFY:+--insecure}` — the first `--insecure` is unconditional, so TLS verification is always skipped regardless of `PROXMOX_TLS_SKIP_VERIFY`.
|
||||
- **Recommendation:** Remove the unconditional `--insecure`, keep only the conditional one.
|
||||
|
||||
### P1-07: MH-12 — lxc-start.sh and ct-exists.sh have comment-only diffs from coreci
|
||||
- lxc-start.sh differs in header comment line 2 ("CoreCI"→"Praxis"); ct-exists.sh differs in comments + path reference (proxy/ → top-level). Functionally identical. The PLAN said "verbatim" but header-comment adaptation is reasonable.
|
||||
- **Recommendation:** Accept as verbatim-equivalent.
|
||||
|
||||
### P1-08: install-service.sh `RestartSec=5` (vs PLAN's `RestartSec=10`)
|
||||
- Minor deviation from PLAN spec (5s vs 10s restart delay). Not functionally significant.
|
||||
- **Recommendation:** Accept.
|
||||
**Recommended next steps:**
|
||||
1. Proceed to P2 (final review + audit + milestone ship).
|
||||
2. Before v0.1.5: schedule the live external-verifier interop run (P1-3) in staging.
|
||||
3. v0.4: address P1-1 (rate-limit), P1-2 (root-key fail-fast), P1-4 (path-score mean).

## 9. Summary
|
||||
|
||||
| Layer | Result |
|
||||
|-------|--------|
|
||||
| Structural | ✅ PASS (1 P0 fixed: docker-compose.yml) |
|
||||
| Behavioral | ✅ PASS (1 P0 fixed: pyproject.toml fastapi/uvicorn) |
|
||||
| Security | ✅ PASS (no issues) |
|
||||
| Quality | ✅ PASS (2 P0 fixed: timing.sh metrics, firstboot-hook idempotency; 1 P1 fixed: lxc-config defaults) |
|
||||
| Must-haves | 25/28 PASS, 2 PARTIAL, 1 DEFERRED |
|
||||
| REQ coverage | 18/20 COVERED, 2 DEFERRED (live E2E) |
|
||||
|
||||
### P0 issues fixed: 4
|
||||
1. docker-compose.yml invalid `restart_policy` key → removed
|
||||
2. pyproject.toml missing `fastapi` + `uvicorn` → added
|
||||
3. timing.sh `coreci_*` metric names → renamed to `praxis_*`
|
||||
4. firstboot-hook.sh idempotency check referencing non-existent binary → fixed to check `/opt/praxis/.git` + service active
|
||||
|
||||
### P1+ issues: 8 (1 fixed, 7 noted)
|
||||
- P1-05 (lxc-config defaults) fixed; P1-01/02/03/04/06/07/08 noted for follow-up.
|
||||
|
||||
### Verdict: **APPROVE_WITH_NOTES**
|
||||
|
||||
Phase 1 is structurally complete and behaviorally sound after the 4 P0 fixes. All 121 bats tests pass, all 77 non-live pytest tests pass, the Docker image builds and serves both the API and client, secrets are properly excluded from git/image, and the G-101/G-102/G-103/G-104/G-105/G-106 grill fixes are all applied. The remaining P1 items are non-blocking (missing Makefile, missing 3 bats files with adequate alternative coverage, comment-only coreci diffs). The 2 deferred REQ-NFR-DEPLOY-03 (live first-boot timing) and MH-28 require a live Proxmox cluster and cannot be verified in this environment — the wiring is correct and ready for live E2E.
|
||||
|
||||
**Files modified by verifier (P0/P1 fixes):**
|
||||
- `docker-compose.yml` — removed invalid `restart_policy`, fixed `env_file` optional syntax, `restart: unless-stopped`
|
||||
- `pyproject.toml` — added `fastapi>=0.110` + `uvicorn>=0.30`
|
||||
- `scripts/proxmox/timing.sh` — renamed `coreci_deploy_timing_*` → `praxis_deploy_timing_*`
|
||||
- `scripts/proxmox/firstboot-hook.sh` — fixed idempotency check (`/usr/local/bin/praxis-deploy` → `/opt/praxis/.git`)
|
||||
- `scripts/proxmox/lxc-deploy.sh` — added secret sourcing from ~/coreci/ + praxis .env.secrets (MH-23)
|
||||
- `scripts/proxmox/lxc-config.sh` — added PRAXIS_HOST + PRAXIS_SCENARIOS_DIR; aligned defaults with .env.example
|
||||
- `scripts/install-service.sh` — `User=root` → `User=praxis` (MH-21)
|
||||
- `.ciagent/config.json` — removed PROXMOX_LXC_VMID from proxmox scope (D-037)
|
||||
- `scripts/proxmox/test/firstboot-hook.bats` — updated comment to match fixed idempotency check

# RESEARCH: Operator Tier — Postgres-in-LXC + Auth for v0.3
|
||||
|
||||
**Scope:** Research only. No code changes. Grounded in the current Praxis repo
|
||||
(`docker-compose.yml` single `praxis` service; `db/store.py` aiosqlite
|
||||
`PraxisStore`; `db/migrate.py` ordered `.sql` migrations; SQLite schema at
|
||||
`db/schema.sql`).
|
||||
|
||||
**Decisions honored:** D-007 (SQLite learner, preserved), D-031 (hybrid:
|
||||
SQLite for learner, Postgres for operator), D-040 (Postgres = second
|
||||
docker-compose service in the existing LXC CT), D-041 (session-cookie auth,
|
||||
argon2id, single operator role, rate-limited).
|
||||
|
||||
**Confidence scores** are 0–1 (1 = well-established practice / low risk).
|
||||
|
||||
---
|
||||
|
||||
## 1. Docker-Compose Shape *(confidence: 0.90)*
|
||||
|
||||
Add a `postgres` service alongside the existing `praxis` service. Key
|
||||
best-practices for a second service in an already-running LXC CT:
|
||||
|
||||
- **Image:** `postgres:16-slim` (Debian-slim base, glibc — matches the
|
||||
praxis Dockerfile rationale; avoids Alpine musl locale issues with
|
||||
`pg_*` clients).
|
||||
- **Persistence:** named volume `pgdata` (driver: local). Never bind-mount
|
||||
`/var/lib/postgresql/data` to the CT filesystem — Postgres requires
|
||||
`chown 999` and a specific directory layout; named volumes handle this.
|
||||
- **Network isolation:** declare an explicit internal compose network and
|
||||
attach **only** `praxis` and `postgres` to it. Do **not** publish
|
||||
`5432` via `ports:`. The `praxis` service keeps its published `8789`.
|
||||
- `internal: true` on the network blocks egress to the host bridge, but
|
||||
note: with `internal: true` the postgres container cannot reach the
|
||||
internet (fine — it doesn't need to). If you later want outbound
|
||||
backups via network, drop `internal: true` and instead rely on
|
||||
*not* publishing the port. The simpler, robust choice for a pilot is:
|
||||
explicit named network, no `ports:` on postgres, no `internal: true`.
|
||||
- **Healthcheck:** `pg_isready -U praxis -d praxis` every 10s, 5 retries,
|
||||
5s timeout. `depends_on: { postgres: { condition: service_healthy } }`
|
||||
on the `praxis` service so the app waits for accept-connections, not
|
||||
just container start.
|
||||
- **Init scripts:** mount `./db/pg/init/*.sql` (or `.sh`) at
|
||||
`/docker-entrypoint-initdb.d/`. These run **only on first boot** (empty
|
||||
`pgdata`). Use them for: role/db creation, schema bootstrap, and
|
||||
idempotent seed. For *versioned* schema changes use a migration runner
|
||||
(see §6) — init scripts are one-shot.
|
||||
- **Env:** `POSTGRES_USER`, `POSTGRES_PASSWORD`, `POSTGRES_DB` from the
|
||||
existing `/etc/praxis/server.env` (do **not** commit secrets to the
|
||||
compose file). Add `PGDATA=/var/lib/postgresql/data/pgdata` to pin the
|
||||
subdirectory (survives image upgrades).
|
||||
- **Restart:** `restart: unless-stopped` (matches praxis).
|
||||
- **Resources:** for a pilot on a small LXC CT, set a mem limit
|
||||
(`deploy.resources.limits.memory: 512m`) and rely on Postgres default
|
||||
`shared_buffers`. Tune later.
|
||||
|
||||
**Sketch (shape only, not for commit):**
|
||||
|
||||
```yaml
|
||||
services:
|
||||
praxis:
|
||||
# ... existing v0.2 fields unchanged ...
|
||||
depends_on:
|
||||
postgres:
|
||||
condition: service_healthy
|
||||
networks: [praxis-net]
|
||||
|
||||
postgres:
|
||||
image: postgres:16-slim
|
||||
restart: unless-stopped
|
||||
environment:
|
||||
POSTGRES_USER: ${PG_USER}
|
||||
POSTGRES_PASSWORD: ${PG_PASSWORD}
|
||||
POSTGRES_DB: ${PG_DB:-praxis_operator}
|
||||
PGDATA: /var/lib/postgresql/data/pgdata
|
||||
env_file:
|
||||
- path: /etc/praxis/server.env
|
||||
required: false
|
||||
volumes:
|
||||
- pgdata:/var/lib/postgresql/data
|
||||
- ./db/pg/init:/docker-entrypoint-initdb.d:ro
|
||||
- pgbackups:/backups
|
||||
healthcheck:
|
||||
test: ["CMD-SHELL", "pg_isready -U ${PG_USER:-praxis} -d ${PG_DB:-praxis_operator}"]
|
||||
interval: 10s
|
||||
timeout: 5s
|
||||
retries: 5
|
||||
networks: [praxis-net]
|
||||
# NOTE: no `ports:` — not exposed to the LXC host bridge.
|
||||
|
||||
volumes:
|
||||
praxis-data:
|
||||
driver: local
|
||||
pgdata:
|
||||
driver: local
|
||||
pgbackups:
|
||||
driver: local
|
||||
|
||||
networks:
|
||||
praxis-net:
|
||||
driver: bridge
|
||||
```
|
||||
|
||||
**Risk callouts:**
|
||||
- If `praxis` currently has no explicit network, compose assigns the
|
||||
default bridge; adding an explicit network means the *existing*
|
||||
`praxis` service gets recreated on `up`. Plan a brief downtime window
|
||||
(see §6).
|
||||
- `pg_isready` returns healthy before the DB is fully ready for migration
|
||||
load; `depends_on: service_healthy` is necessary but not sufficient —
|
||||
the app must still retry the first migration attempt.
|
||||
|
||||
---
|
||||
|
||||
## 2. Connection Management *(confidence: 0.85)*
|
||||
|
||||
Two async DB drivers in one process: **aiosqlite** (already a dep) for the
|
||||
learner store, **asyncpg** for the operator store.
|
||||
|
||||
- **Pools are independent and must not be shared.** asyncpg uses a
|
||||
`asyncpg.create_pool(...)` (sized pool, real connections). aiosqlite
|
||||
opens a fresh connection per `async with aiosqlite.connect(...)` (the
|
||||
current `PraxisStore._connect` pattern). They have nothing in common —
|
||||
different backends, different lifecycles. **Do not** wrap them in a
|
||||
single shared `AsyncSession` object; SQLAlchemy's async session is an
|
||||
option *only if* you adopt SQLAlchemy for both — that's a larger
|
||||
refactor and not warranted for v0.3.
|
||||
- **Pool sizing (avoid exhaustion):**
|
||||
- asyncpg pool: `min_size=2, max_size=10` for a pilot single-instance.
|
||||
Operator endpoints are low-frequency (cohort dashboard, VC issuance).
|
||||
- aiosqlite: no pool; the current pattern opens/closes per call. SQLite
|
||||
is single-writer; keep `WAL` mode and short transactions. This is
|
||||
already fine for one learner.
|
||||
- Total concurrent DB connections ≈ asyncpg(10) + aiosqlite(1-2). On a
|
||||
small CT this is trivial. Exhaustion risk is essentially zero at
|
||||
pilot scale; revisit if operator endpoints are hit by N concurrent
|
||||
cohort users.
|
||||
- **Lifecycle:** create the asyncpg pool once at FastAPI startup
|
||||
(`lifespan` context manager), close on shutdown. Store on
|
||||
`app.state.pg_pool`. The `PraxisStore` keeps its current per-call
|
||||
connect pattern (no change to D-007 code path).
|
||||
- **Transaction boundaries:** asyncpg use `pool.acquire()` +
|
||||
`conn.transaction()` for multi-statement writes; aiosqlite unchanged.
|
||||
- **Config:** `PG_DSN` env var, e.g.
|
||||
`postgresql://praxis:***@postgres:5432/praxis_operator` (host =
|
||||
service name on `praxis-net`).
|
||||
- **Statement timeout:** set `command_timeout=10` on the asyncpg pool to
|
||||
prevent a slow operator query from blocking the event loop.
|
||||
|
||||
**Pip:** `asyncpg>=0.29` (new dep). `aiosqlite>=0.20` already present.
|
||||
|
||||
---
|
||||
|
||||
## 3. Auth Stack *(confidence: 0.90 for the stack; 0.70 for rate-limit choice)*
|
||||
|
||||
D-041 spec: session-cookie, argon2id, single operator role, rate-limited.
|
||||
|
||||
### 3a. Session cookie
|
||||
- **`starlette` `SessionMiddleware`** (FastAPI bundles Starlette). Uses
|
||||
`itsdangerous` to sign the cookie — no server-side session store
|
||||
needed (stateless, fits single-instance LXC). Data lives in the cookie
|
||||
itself, signed with `SECRET_KEY`.
|
||||
- **Settings:**
|
||||
- `secret_key`: from env, ≥32 bytes random. **Rotate** by changing the
|
||||
key (invalidates all sessions — acceptable for a pilot).
|
||||
- `session_cookie`: `"praxis_op"` (distinct from any future learner
|
||||
cookie name).
|
||||
- `max_age`: `28800` (8h, per D-041).
|
||||
- `path`: `/` (or scope to `/op` if operator routes live under a
|
||||
prefix — cleaner).
|
||||
- `https_only`: `True` (Secure flag). **Requires TLS** — the LXC
|
||||
deployment must terminate TLS (reverse proxy / Caddy / Proxmox
|
||||
level). If running plain HTTP on the LAN for the pilot, set to
|
||||
`False` *temporarily* and document the risk; never ship False.
|
||||
- `httponly`: `True` (the middleware sets this by default; verify).
|
||||
- `samesite`: `"strict"` (D-041). CSRF defense-in-depth; with Strict,
|
||||
no credential is sent on cross-site navigations.
|
||||
- **Cookie contents:** store `{operator_id: str, issued_at: epoch}`.
|
||||
**Never** store the password hash or any PII. Roles aren't needed in
|
||||
the cookie yet (single role — see §4).
|
||||
|
||||
### 3b. Password hashing — argon2id
|
||||
- **`argon2-cffi`** (`PasswordHasher` default is argon2id, RFC 9106).
|
||||
Pip: `argon2-cffi>=23.1`.
|
||||
- On login: `ph.verify(stored_hash, password)` → on success,
|
||||
`ph.check_needs_rehash(stored_hash)` → rehash if params bumped.
|
||||
- Params: keep `PasswordHasher()` defaults for v0.3
|
||||
(`time_cost=3, memory_cost=64MiB, parallelism=4` — reasonable on a
|
||||
small CT; benchmark and tune if login latency > 1s).
|
||||
- Store the hash as `TEXT` in `operators.password_hash`.
|
||||
|
||||
### 3c. Rate limiting
|
||||
Two options:
|
||||
1. **`slowapi`** (pip `slowapi>=0.1`) — the idiomatic FastAPI choice.
|
||||
Decorator/IP-based limiter. Default in-memory backend is fine for
|
||||
single-instance. **Confidence 0.70** — it works, but it's a young lib
|
||||
and the in-memory backend is per-process (breaks if you ever scale to
|
||||
>1 praxis process; not a v0.3 concern).
|
||||
2. **In-memory counter** (a simple `dict[remote_ip, (count, window_start)]`
|
||||
in a small dependency) — zero deps, trivially auditable. For a single
|
||||
operator login endpoint this is enough. **Confidence 0.80** for the
|
||||
pilot specifically.
|
||||
|
||||
**Recommendation:** start with `slowapi` on the login route only
|
||||
(`@limiter.limit("5/minute")`), in-memory backend. Migrate to a Redis
|
||||
backend only if/when you go multi-instance. Threshold: 5 failed
|
||||
attempts/minute/IP → 429 + exponential backoff marker.
|
||||
|
||||
**Pip additions:** `argon2-cffi>=23.1`, `slowapi>=0.1`. (`starlette` and
|
||||
`itsdangerous` come with FastAPI.)
|
||||
|
||||
---
|
||||
|
||||
## 4. Auth Dependency Pattern *(confidence: 0.90)*
|
||||
|
||||
Single-role v0.3 → **no RBAC framework needed.** A single FastAPI
|
||||
`Depends` that resolves the operator from the signed session is the
|
||||
minimal secure shape.
|
||||
|
||||
Concept (not committed code):
|
||||
|
||||
```python
|
||||
# pseudo — shape only
|
||||
async def current_operator(request: Request) -> Operator:
|
||||
sess = request.session # populated by SessionMiddleware
|
||||
op_id = sess.get("operator_id")
|
||||
if not op_id:
|
||||
raise HTTPException(401, "not authenticated")
|
||||
op = await pg_store.get_operator(op_id)
|
||||
if not op or not op.is_active:
|
||||
# invalidate the cookie
|
||||
request.session.clear()
|
||||
raise HTTPException(401, "operator not found / disabled")
|
||||
return op
|
||||
```
|
||||
|
||||
- Apply via `Depends(current_operator)` on every operator-tier router.
|
||||
Group operator routes under an `APIRouter(prefix="/op")` and attach
|
||||
the dependency at the router level
|
||||
(`dependencies=[Depends(current_operator)]`) — one declaration, not
|
||||
per-endpoint.
|
||||
- Login/logout are **outside** the protected router (login is rate-
|
||||
limited, not auth-gated).
|
||||
- **CSRF:** with `SameSite=Strict` + `httponly` cookies, CSRF surface is
|
||||
minimal for state-changing requests. If any operator endpoint accepts
|
||||
`Content-Type: application/x-www-form-urlencoded`/`multipart` (form
|
||||
posts), add a double-submit token or require `Content-Type:
|
||||
application/json` only (the latter is the cheaper defense — JSON
|
||||
bodies are not auto-sent by browsers across origins).
|
||||
|
||||
### When to migrate to RBAC
|
||||
Migrate when **any** of these become true:
|
||||
- A second role appears (admin, auditor, reviewer) — i.e. v0.4+ if the
|
||||
pilot expands.
|
||||
- Permissions diverge *within* a role (e.g. some operators can issue
|
||||
VCs, others can only view cohorts).
|
||||
- You need row-level visibility rules (operator A sees only their
|
||||
cohort).
|
||||
|
||||
At that point the cheapest upgrade is: add a `role` column to
|
||||
`operators`, split `current_operator` into `current_operator` (any
|
||||
authenticated) + `require_role("admin")` (a parametrized dependency
|
||||
checking `op.role`). Reach for a full RBAC lib (`casbin`,
|
||||
`fastapi-permissions`) only when the role matrix exceeds ~3 roles × ~5
|
||||
permissions. **Don't pre-build it.**
|
||||
|
||||
---
|
||||
|
||||
## 5. Postgres Schema *(confidence: 0.80)*
|
||||
|
||||
Operator-tier tables. Types chosen for Postgres 16 specifically
|
||||
(`TIMESTAMPTZ`, `BIGSERIAL`, `GENERIC` via `JSONB`).
|
||||
|
||||
### `operators`
|
||||
```
|
||||
id UUID PRIMARY KEY DEFAULT gen_random_uuid()
|
||||
username TEXT NOT NULL UNIQUE
|
||||
password_hash TEXT NOT NULL -- argon2id
|
||||
display_name TEXT NOT NULL
|
||||
role TEXT NOT NULL DEFAULT 'operator' -- reserved for §4 migration
|
||||
is_active BOOLEAN NOT NULL DEFAULT TRUE
|
||||
created_at TIMESTAMPTZ NOT NULL DEFAULT now()
|
||||
last_login_at TIMESTAMPTZ
|
||||
```
|
||||
- Index: unique on `username` (covered by constraint). No extra index
|
||||
needed at single-operator scale.
|
||||
- Requires `pgcrypto` extension **or** Postgres 13+ (where
|
||||
`gen_random_uuid()` is built-in via `pgcrypto` shipped default —
|
||||
actually: `gen_random_uuid()` is built into core as of PG 13). So no
|
||||
extension needed on PG16. ✓
|
||||
|
||||
### `issued_credentials`
|
||||
```
|
||||
id BIGSERIAL PRIMARY KEY
|
||||
operator_id UUID NOT NULL REFERENCES operators(id)
|
||||
learner_ref TEXT, -- opaque ref into SQLite side (no FK cross-DB)
|
||||
vc_type TEXT NOT NULL -- 'mastery' | 'completion' | ...
|
||||
payload_jsonb JSONB NOT NULL -- the W3C VC document (signed elsewhere)
|
||||
issued_at TIMESTAMPTZ NOT NULL DEFAULT now()
|
||||
revoked_at TIMESTAMPTZ
|
||||
```
|
||||
- Indices:
|
||||
- `issued_credentials(operator_id, issued_at DESC)` — operator's
|
||||
issuance log.
|
||||
- `issued_credentials(learner_ref)` — lookup by learner (k-anon
|
||||
aggregate joins).
|
||||
- `issued_credentials(vc_type)` if filtering by type is a dashboard
|
||||
query.
|
||||
|
||||
### `mastery_gate_events`
|
||||
```
|
||||
id BIGSERIAL PRIMARY KEY
|
||||
learner_ref TEXT NOT NULL
|
||||
scenario_id TEXT NOT NULL
|
||||
path_id TEXT NOT NULL -- learning path
|
||||
gate_outcome TEXT NOT NULL -- 'pass' | 'fail' | 'retry'
|
||||
recorded_at TIMESTAMPTZ NOT NULL DEFAULT now()
|
||||
source TEXT NOT NULL DEFAULT 'sync' -- 'sync' from SQLite learner store
|
||||
```
|
||||
- Indices:
|
||||
- `(learner_ref, recorded_at DESC)` — per-learner timeline.
|
||||
- `(path_id, recorded_at)` — feeds the cohort aggregate.
|
||||
|
||||
### `cohort_aggregates` — k-anonymized
|
||||
Model as **pre-materialized rows** partitioned by `(path_id, week)` with
|
||||
a minimum bin size enforced at write time (k≥K, e.g. K=5). A 7-day
|
||||
window is a rolling construct over the weekly partitions.
|
||||
|
||||
```
|
||||
path_id TEXT NOT NULL
|
||||
week_start DATE NOT NULL -- ISO week Monday
|
||||
bin_count INTEGER NOT NULL -- learners in this bin
|
||||
k_anon_pass INTEGER NOT NULL -- pass count, suppressed if < K
|
||||
k_anon_fail INTEGER NOT NULL -- fail count, suppressed if < K
|
||||
median_attempts INTEGER
|
||||
updated_at TIMESTAMPTZ NOT NULL DEFAULT now()
|
||||
PRIMARY KEY (path_id, week_start)
|
||||
```
|
||||
- **k-anon rule:** when materializing, if `bin_count < K` emit
|
||||
`bin_count = <K-masked>` and null-out the count columns (or clamp
|
||||
them to K). Enforce in the aggregation job, **not** in a SQL view, so
|
||||
the suppression is auditable at write time.
|
||||
- **7-day window:** compute on read as a window function over the last
|
||||
≤2 weekly partitions, or maintain a parallel rolling table. For a
|
||||
pilot, compute on read:
|
||||
`SUM(k_anon_pass) ... WHERE week_start >= now()::date - interval '7 days'`.
|
||||
- Indices: PK covers `(path_id, week_start)`. Add a secondary
|
||||
`(week_start DESC)` only if you query "all paths for the latest week"
|
||||
frequently.
|
||||
|
||||
**General indices summary:** 4 indices beyond PKs/constraints for v0.3
|
||||
— keep it lean; add per slow-query evidence.
|
||||
|
||||

|
||||
## 6. Migration Strategy *(confidence: 0.85)*
|
||||
|
||||
Goal: add Postgres to the **running** v0.2 LXC CT without breaking the
|
||||
learner service.
|
||||
|
||||
### Steps (ordered, low-risk)
|
||||
1. **Prepare on a staging CT first** (clone the production LXC CT in
|
||||
Proxmox). Never test the migration path on the live CT.
|
||||
2. **Add the `postgres` service + `praxis-net` + volumes** to
|
||||
`docker-compose.yml`. The `praxis` service gains
|
||||
`depends_on: postgres (service_healthy)` and joins `praxis-net`.
|
||||
3. **Add init scripts** under `db/pg/init/`:
|
||||
- `00_create_schema.sql` — the four tables from §5.
|
||||
- `01_seed_operator.sh` — creates the initial operator with an
|
||||
argon2id hash (run from env-supplied temp password; force password
|
||||
change on first login).
|
||||
These run **only on first boot** of an empty `pgdata` volume.
|
||||
4. **Add the asyncpg pool + operator store + auth wiring** to the praxis
|
||||
image (new code paths, new deps in `pyproject.toml`). Learner paths
|
||||
(`db/store.py`, `db/migrate.py`) **unchanged** — D-007 preserved.
|
||||
5. **Build the new image** (`docker compose build praxis`) — does not
|
||||
touch the running container.
|
||||
6. **Controlled cutover:**
|
||||
- `docker compose up -d postgres` → wait for healthy.
|
||||
- `docker compose up -d praxis` → recreate the praxis container with
|
||||
the new image. Expect ~5–15s of downtime (the learner voice loop
|
||||
is not HA anyway). The SQLite volume (`praxis-data`) is untouched,
|
||||
so learner state is preserved across the recreate.
|
||||
7. **Smoke tests:** `/health`, learner voice loop, operator login, one
|
||||
cohort-dashboard read.
|
||||
8. **Rollback plan:** if operator endpoints misbehave, revert the
|
||||
praxis image tag and `docker compose up -d praxis` again — Postgres
|
||||
stays up but unused. Learner path is independent, so a bad operator
|
||||
rollout does **not** regress v0.2 learner behavior. This is the
|
||||
core safety property of the hybrid (D-031) design.
|
||||
|
||||
### Versioned migrations beyond first boot
|
||||
The SQLite side already has `db/migrate.py` (ordered `.sql`, `_migrations`
|
||||
table). For Postgres, two options:
|
||||
- **(a) Reuse the pattern:** a `pg_migrate.py` mirroring the SQLite
|
||||
runner, against a `_pg_migrations` table. Lowest cognitive load —
|
||||
same mental model, same directory convention (`db/pg/migrations/`).
|
||||
- **(b) Adopt `yoyo-migrations` or `alembic`:** more machinery, not
|
||||
warranted at 4 tables.
|
||||
|
||||
**Recommendation (a):** mirror the existing runner. Run on praxis
|
||||
startup (after the pool is up), idempotent. **Confidence 0.80** on the
|
||||
pattern; it's exactly what v0.2 already does for SQLite.
|
||||
|
||||
---
|
||||
|
||||
## 7. Backup *(confidence: 0.85)*
|
||||
|
||||
Minimum viable backup for a pilot operator Postgres in LXC:
|
||||
|
||||
- **Method:** `pg_dump -Fc` (custom compressed format) → file in the
|
||||
`pgbackups` volume. `-Fc` gives you selective restore and parallel
|
||||
restore later.
|
||||
- **Frequency:** daily is enough for a pilot. A cron job *inside the
|
||||
postgres container* (or a sidecar) runs:
|
||||
```
|
||||
pg_dump -U praxis -Fc praxis_operator > /backups/pg_$(date +%u).dump
|
||||
```
|
||||
Using `%u` (day-of-week 1–7) gives a rolling 7-file retention with
|
||||
zero cleanup logic.
|
||||
- **Where:** `/backups` is the `pgbackups` named volume. Keep backups
|
||||
**inside the compose stack** so they move with the CT. For off-CT
|
||||
safety: a Proxmox-level cron `pct push`/`rsync` of the `pgbackups`
|
||||
volume to the Proxmox host or a NAS — out of scope for the app, but
|
||||
the named volume makes it a one-line host-side copy.
|
||||
- **Restore (drill it once):**
|
||||
```
|
||||
docker compose exec postgres pg_restore -U praxis -d praxis_operator \
|
||||
--clean --if-exists /backups/pg_3.dump
|
||||
```
|
||||
`--clean --if-exists` drops+recreates objects; safe against a
|
||||
partially-populated DB. **Never** restore into the live DB without
|
||||
stopping the praxis service first.
|
||||
- **Don't back up** the SQLite side here — it's already on the
|
||||
`praxis-data` volume and covered by whatever volume backup the CT
|
||||
already has. Keep the two backup streams separate (matches the hybrid
|
||||
design).
|
||||
- **Encryption at rest:** out of scope for the MVP; rely on LXC/Proxmox
|
||||
disk encryption. If the `pgbackups` volume is ever pulled off-host,
|
||||
`gpg -c` the dump in the cron step.
|
||||
|
||||
**Pip:** none new for backup (uses `pg_dump`/`pg_restore` shipped with
|
||||
the postgres image).
|
||||
|
||||

|
||||
|
||||
## Summary table — new pip dependencies
|
||||
|
||||
| Dep | Purpose | Confidence |
|
||||
|---|---|---|
|
||||
| `asyncpg>=0.29` | Postgres async driver / pool | 0.90 |
|
||||
| `argon2-cffi>=23.1` | argon2id password hashing | 0.95 |
|
||||
| `slowapi>=0.1` | login rate limiting (in-memory) | 0.70 |
|
||||
| `starlette` (already via FastAPI) | `SessionMiddleware` signed cookies | 0.95 |
|
||||
| `itsdangerous` (already via Starlette) | cookie signing | 0.95 |
|
||||
|
||||
## Cross-cutting risks (watch list)
|
||||
|
||||
1. **TLS or not:** Secure cookie flag requires TLS. Confirm the LXC
|
||||
fronting layer terminates HTTPS before enabling `https_only=True`.
|
||||
2. **First-boot-only init scripts:** if `pgdata` already exists (e.g.
|
||||
after a failed first boot), seed scripts **won't re-run** — keep a
|
||||
separate re-runnable seed path (the `01_seed_operator.sh` should be
|
||||
idempotent via `ON CONFLICT DO NOTHING` or a shell guard).
|
||||
3. **Two migration runners** (SQLite + Postgres) — keep directory
|
||||
layouts visually distinct: `db/migrations/` (SQLite, existing) vs
|
||||
`db/pg/migrations/` (Postgres, new). Don't merge.
|
||||
4. **Event-loop blocking:** argon2id hashing is CPU-bound
|
||||
(`time_cost=3` ≈ 30–80ms). For a single operator login this is fine
|
||||
on the main event loop; if you ever batch-hashed, move to
|
||||
`run_in_executor`. Not a v0.3 concern.
|
||||
5. **Cross-DB joins are impossible** (SQLite ↔ Postgres). Anything that
|
||||
needs both (e.g. a dashboard joining learner sessions to issued VCs)
|
||||
must be assembled in application code. The `learner_ref` opaque key
|
||||
in `issued_credentials`/`mastery_gate_events` is the join handle —
|
||||
keep it stable and never reuse SQLite rowids directly (use the
|
||||
existing `sess-…`/`learner-1` string ids).

# Mastery Scoring Research — v0.3 Rubric & Mastery Gate Design
|
||||
|
||||
**Scope:** Research-only synthesis to inform D-032 (N=3 + rubric mean ≥ 3.5), D-038 (rule-based final score, LLM-assisted extraction), D-039 (rubrics/<skill>.yaml). No code changes. Each section ends with a confidence score (0–1) reflecting strength of the literature backing, not certainty of the decision.

|
||||
## 1. Rubric Models
|
||||
|
||||
### Candidate frameworks
|
||||
|
||||
| Model | Unit of growth | Fit for voice role-play | Notes |
|
||||
|---|---|---|---|
|
||||
| **Bloom's Taxonomy (revised, Anderson & Krathwohl 2001)** | Cognitive complexity (Remember → Understand → Apply → Analyze → Evaluate → Create) | Partial. Role-play is *performative*, not cognitive recall. Useful for tagging scenario difficulty but weak as a scoring spine. | Originally for educational objectives; not a performance rubric. |
|
||||
| **Bloom's Mastery Learning (Bloom 1968; Block 1971)** | Threshold attainment + corrective remediation | Strong fit. Defines mastery as "≥80% on criterion-referenced test before advancing." Directly motivates the N-of-M gate + remediation loop. | This is the *gating* philosophy behind D-032. |
|
||||
| **Dreyfus & Dreyfus Skill Acquisition Model (1980/1986)** | Novice → Advanced Beginner → Competent → Proficient → Expert (5 stages) | Strong fit for 5-level anchors. Stages are defined by *behavioral cues* (rule-following vs. holistic recognition), which map cleanly to voice performance. | Widely adopted in nursing (Benner 1982) and pilot training. |
|
||||
| **Miller's Pyramid (1990)** | Knows → Knows how → Shows how → Does | Excellent fit. The "Does" tier is exactly what a voice role-play measures. CBME standard for performance assessment. | Standard in medicine; complements Dreyfus. |
|
||||
| **Entrustable Professional Activities (ten Cate 2005)** | Trust-based supervision levels (1: observe → 5: supervise others) | Strong fit for "do the job" framing. Each EPA has its own 5-level entrustment scale; directly maps to "can this learner be trusted to handle a refund call unsupervised?" | Increasingly the dominant CBME rubric model. |
|
||||
| **CBE / CBE Network (C-BEN 2023) quality principles** | Competency defined by employer-validated outcomes | Good fit at the *system* level (criteria must be employer-validated, criterion-referenced, transparent). Not a scoring scale itself. | Use for governance of D-039 rubric content. |
|
||||
|
||||
### Recommendation (confidence: **0.82**)
|
||||
|
||||
Use a **hybrid: Dreyfus 5-stage anchors + Miller's "Does" tier as the assessment mode + EPA entrustment language for level-5 + Bloom mastery learning for the gate philosophy.**
|
||||
|
||||
Rationale:
|
||||
- Dreyfus gives the *behavioral anchor language* for the 5-level rubric (D-039's "5-level anchors"). Each level describes observable behavior, not abstract cognition — ideal for transcribed speech.
|
||||
- Miller's "Does" tier justifies assessing via a simulated-but-realistic voice scenario rather than a quiz.
|
||||
- EPA entrustment language ("can be trusted to do this unsupervised") gives level-5 a defensible ceiling that isn't just "more of level-4."
|
||||
- Bloom's mastery learning legitimizes the **gate** (D-032): advance only after demonstrated criterion performance, with remediation — not after time-on-task.
|
||||
|
||||
Bloom's *Taxonomy* alone is the weakest fit (it's not a performance rubric). Do not use it as the scoring spine.
|
||||
|
||||
---
|
||||
|
||||
## 2. 5-Level Anchoring Example — Customer Service (refund/complaint)
|
||||
|
||||
Anchors follow Dreyfus behavioral cues and EPA entrustment language. Level 5 = "trusted to handle unsupervised and to coach peers." Level 1 = "fails to perform; requires intervention." Levels 2–4 are the intermediate behavioral stages.
|
||||
|
||||
### 2.1 Empathy / Emotional Attunement
|
||||
|
||||
| Lvl | Label | Anchor (observable in transcript) |
|
||||
|---|---|---|
|
||||
| 1 | Fail | No acknowledgement of emotion; jumps straight to policy/transactional response. Customer feels unheard. |
|
||||
| 2 | Advanced Beginner | Cites a scripted empathy line ("I understand your frustration") but moves on mechanically; no follow-up. |
|
||||
| 3 | Competent | Names the emotion in own words, validates it, then transitions to resolution. Appropriate but not tailored. |
|
||||
| 4 | Proficient | Adjusts tone to customer's emotional state mid-call; reflects back specifics ("cracked on arrival — that's frustrating"). |
|
||||
| 5 | Mastery / Entrustable | Reads shifting emotional cues across the call; de-escalates implicitly through pacing and acknowledgment; could model this for new hires. |
|
||||
|
||||
### 2.2 Resolution Concreteness
|
||||
|
||||
| Lvl | Label | Anchor |
|
||||
|---|---|---|
|
||||
| 1 | Fail | Vague ("we'll look into it") or no resolution offered; customer left without a path. |
|
||||
| 2 | Advanced Beginner | Offers a resolution but missing key specifics (no timeline, no method, no amount). |
|
||||
| 3 | Competent | Offers a concrete resolution with method (refund/replacement), amount/channel, and next step. |
|
||||
| 4 | Proficient | Offers a *decision-tree* of concrete options matched to the customer's stated preference; confirms acceptance. |
|
||||
| 5 | Mastery / Entrustable | Tailors resolution to policy + customer constraint, names the exception/risk considered, and closes the loop with a verification step. |
|
||||
|
||||
### 2.3 De-escalation
|
||||
|
||||
| Lvl | Label | Anchor |
|
||||
|---|---|---|
|
||||
| 1 | Fail | Defensive, blames customer/company policy, or matches the customer's escalation. |
|
||||
| 2 | Advanced Beginner | Avoids escalation but through avoidance/deflection rather than active de-escalation. |
|
||||
| 3 | Competent | Uses an explicit de-escalation move (acknowledge → reframe → offer), one cycle. |
|
||||
| 4 | Proficient | Cycles through acknowledge/reframe as needed; lowers intensity without conceding policy inappropriately. |
|
||||
| 5 | Mastery / Entrustable | Prevents re-escalation by reading early signals; preserves relationship and policy simultaneously. |
|
||||
|
||||
### 2.4 Professionalism / Conduct
|
||||
|
||||
| Lvl | Label | Anchor |
|
||||
|---|---|---|
|
||||
| 1 | Fail | Unprofessional language, breaks role, gives prohibited advice (legal/medical/financial), or insults customer. |
|
||||
| 2 | Advanced Beginner | Mostly professional but uses jargon ("RMA", "SLA") or breaks tone once. |
|
||||
| 3 | Competent | Plain-language, in-role throughout, no prohibited advice. |
|
||||
| 4 | Proficient | Adapts register to customer; concise for voice (1–3 sentences); manages silence well. |
|
||||
| 5 | Mastery / Entrustable | Consistently concise, on-brand, voice-appropriate; could serve as a call-center exemplar. |
|
||||
|
||||
### Note on anchor design (confidence: **0.78**)
|
||||
- Anchors must describe **observable behavior in the transcript**, not internal states (per good-rubric principles: Jonsson & Svingby 2007; Reddy & Andrade 2010).
|
||||
- Level 3 ("Competent") should be the *passing threshold* and defined as "what a competent entry-level hire would do unsupervised." This makes the 3.5 mean gate (D-032) interpretable as "averaging between Competent and Proficient."
|
||||
- Avoid **evasion anchors** ("somewhat", "mostly") — they destroy inter-rater reliability (Wolfe & Chiu 1997; Barkaoui 2010). The anchors above are behavior-specific.
|
||||
|
||||

|
||||
|
||||
## 3. Mastery Gate N Defensibility (D-032: N=3)
|
||||
|
||||
### What the literature says about N-of-M mastery gates
|
||||
|
||||
- **Bloom (1968) / Block (1971):** Mastery learning classically requires one demonstration at ≥80% but with *corrective instruction between attempts*. The "N" is not the central variable — the *remediation loop* is. Bloom's evidence is on gain, not on N.
|
||||
- **Mastery learning meta-analyses (Kulik, Kulik & Bangert-Drowns 1990; Guskey 2007):** Effect sizes are large (~0.5–0.7 SD) but studies use N=1 with remediation; little direct evidence on N≥2.
|
||||
- **CBME / EPAs (ten Cate 2015; ten Cate & Chen 2018):** Entrustment decisions for an EPA typically require **multiple observations across contexts**. Common recommendations:
|
||||
- **5–10 observations** per EPA is a frequently cited minimum for *high-stakes* entrustment (e.g., surgical EPAs, Rekman et al. 2016).
|
||||
- The ACGME milestone framework treats low-stakes formative entrustment at N=1–2; high-stakes summative at N≥5 with multiple assessors.
|
||||
- **Generalizability theory (Crossley et al. 2002; Bloch & Bogo 2007):** For performance assessments, a single observation has low generalizability (G-coefficients often 0.5–0.7). Generalizability improves with **both** more scenarios *and* more assessors. For voice role-play with one AI assessor, the *scenario count* carries essentially all the reliability burden.
|
||||
- **Standard setting (Norcini & Guille 2002; Cusimano 2014):** High-stakes credentialing exams typically use multi-stage blueprints sampling **multiple content domains** — 3 is on the low end; 6–12 is common for high-stakes OSCEs (Pell et al. 2010).
|
||||
- **Angoff / Ebel methods:** Not directly about N, but the standard-setting tradition implies you sample enough items (scenarios) to cover the blueprint reliably. 3 is thin blueprint coverage.
|
||||
|
||||
### Is N=3 defensible? (confidence: **0.62**)
|
||||
|
||||
**Defensible as a formative / low-stakes gate; not defensible as a high-stakes credential on its own.**
|
||||
|
||||
Arguments for N=3:
|
||||
- Praxis v0.3 is positioning a "path" credential, not a license to practice. If the credential is employer-facing *internal advancement* (not regulatory), N=3 across *distinct* scenarios satisfies the CBE principle of "demonstrated across contexts" weakly but coherently.
|
||||
- Distinctiveness requirement (D-032 says "distinct scenarios") is the right lever — it's the breadth, not the raw count, that addresses generalizability.
|
||||
|
||||
Arguments against N=3 (for high-stakes):
|
||||
- A single AI assessor means rater variance is not averaged out; all reliability rides on scenario sampling. G-theory suggests N=3 yields G ≈ 0.5–0.6 — below the 0.8 conventional threshold for high-stakes decisions (Brennan 2001).
|
||||
- 3 scenarios barely covers a blueprint (refund + complaint + escalation = 3 nodes). Real CS skill has more sub-domains.
|
||||
|
||||
### Recommended posture (confidence: **0.70**)
|
||||
1. **Label the v0.3 credential explicitly as "formative" or "path completion"** — not "certification." This makes N=3 defensible.
|
||||
2. **Add a "high-stakes" tier at N=5–6 distinct scenarios** with blueprint coverage required (≥1 per sub-skill cluster) as the defensible high-stakes threshold. Cite CBME/EPA literature (Rekman 2016; ten Cate 2018) and G-theory (Crossley 2002).
|
||||
3. **Keep the remediation loop** between attempts — that's where Bloom's mastery-learning effect actually lives. N=3 *without* remediation is weaker than N=1 *with* remediation.
|
||||
4. **Raise the mean rubric gate from 3.5 to ≥3.5 on each scenario, not just the path mean**, if high-stakes. A path mean of 3.5 can hide a single failing scenario (e.g., 5, 5, 2 → mean 4.0). See §4 for the additive-vs-gating question.
|
||||
5. Track observed rater-Drift of the LLM extractor over time (D-038); if inter-scenario correlations collapse, N must rise.
|
||||

|
||||
|
||||
## 4. Mastery Score Computation
|
||||
|
||||
### 4.1 How to combine criteria → scenario score
|
||||
|
||||
Options:
|
||||
- **(a) Weighted mean of criterion scores** (D-039 has per-skill weights).
|
||||
- **(b) Conjunctive / min-rule** — pass only if *every* criterion ≥ threshold (common in CBME milestone systems; ACGME uses conjunctive for this reason — "no criterion unaddressed").
|
||||
- **(c) Compensatory mean** — high scores compensate low (what weighted mean implies).
|
||||
- **(d) Hybrid** — minimum floor on critical criteria + weighted mean for the rest (used in many medical licensing rubrics, e.g., MRCP clinical exam).
|
||||
|
||||
**Recommendation (confidence: 0.74):** Use **(d) hybrid: weighted mean with a floor on critical criteria.** Specifically:
|
||||
- Compute weighted mean of criterion scores (1–5) using D-039 per-skill weights.
|
||||
- Apply a **floor**: scenario passes only if *every* criterion scored ≥ 2 AND the weighted mean ≥ 3.0 (D-032 sets ≥ 3.5 at the path level).
|
||||
- Rationale: A learner who scores 5 on resolution and 1 on professionalism should *not* pass a refund scenario — the floor catches this. The literature strongly favors conjunctive rules for *safety-critical* dimensions (Norcini 2003; Wass et al. 2001 on OSCEs); a hybrid is a pragmatic compromise between conjunctive strictness and compensatory flexibility.
|
||||
|
||||
### 4.2 How to combine scenario scores → path Mastery Score
|
||||
|
||||
**Additive vs gating — the answer is *both*, at different layers.**
|
||||
|
||||
- **Gating layer (qualitative):** The N-of-M distinct-scenario pass requirement (D-032) is a **gate**, not a sum. You must pass each of N distinct scenarios. This satisfies the "varied-context mastery" requirement from CBME/EPA literature (ten Cate 2018 — entrustment requires demonstrated generalization).
|
||||
- **Additive layer (quantitative Mastery Score):** On top of the gate, compute a numeric Mastery Score as the **weighted mean of scenario scores**, where scenario weights reflect blueprint importance (e.g., harder scenarios weighted higher). This gives a continuous signal for ranking/cohort comparison and for the "rubric mean ≥ 3.5" gate in D-032.
|
||||
|
||||
**Specific formula recommendation (confidence: 0.72):**
|
||||
|
||||
```
|
||||
MasteryScore(path) = Σ_s ( w_s · ScenarioScore_s ) / Σ_s w_s
|
||||
|
||||
where ScenarioScore_s = Σ_c ( w_c · CriterionScore_{s,c} ) / Σ_c w_c
|
||||
subject to floor: ∀c, CriterionScore_{s,c} ≥ 2
|
||||
pass s ⇔ ScenarioScore_s ≥ 3.0 (scenario pass threshold)
|
||||
pass path ⇔ (≥3 distinct scenarios passed) ∧ (MasteryScore ≥ 3.5)
|
||||
```
|
||||
|
||||
This satisfies D-032 exactly: the rubric mean ≥ 3.5 is computed on the *passing* scenarios only (otherwise failed scenarios would drag down a credential earned by passing 3 distinct ones). Decide and document whether MasteryScore is computed over (a) all attempted scenarios or (b) only passing scenarios — **recommend (b)** to align with "mastery" semantics.
|
||||
|
||||
### 4.3 Why not just sum?
|
||||
A sum (e.g., "passed 3 of 5 scenarios") loses information about *how well* and creates a perverse incentive to attempt many easy scenarios. The gate + weighted-mean hybrid avoids this.
|
||||
|
||||
---
|
||||
|
||||
## 5. Deterministic Scoring Patterns (D-038: LLM extracts, rules score)
|
||||
|
||||
The core problem: free-form speech → reproducible score. The D-038 split (LLM-extracts-evidence, rules-score-evidence) is well-aligned with the literature on **structured rubric scoring from natural language**.
|
||||
|
||||
### 5.1 The pattern
|
||||
|
||||
Two-stage pipelines are the documented way to control LLM variability in assessment (Latif & Zhai 2024 on LLM-as-judge; Chiang & Lee 2023 on explanation-first prompting):
|
||||
|
||||
1. **Extraction stage (LLM, allowed to vary):** The LLM is constrained to *extract evidence* — verbatim quotes + structured tags — not to score. Output is a JSON/structured record like:
|
||||
```
|
||||
{ "criterion": "empathy",
|
||||
"evidence_quotes": ["I'm sorry the item arrived cracked — that's frustrating."],
|
||||
"evidence_signals": ["named_emotion", "acknowledged_specific", "no_policy_first"],
|
||||
"absence_signals": [] }
|
||||
```
|
||||
Key: the LLM does **not** emit a number. It emits *what it observed*. This is the documented "evidence-centered design" pattern (Mislevy, Steinberg & Almond 2003) and matches D-038.
|
||||
|
||||
2. **Scoring stage (deterministic rules):** A rule function maps `evidence_signals` (+ absence) to a level 1–5 per criterion, per a published lookup table embedded in `rubrics/<skill>.yaml`. Identical input → identical output. No LLM in this stage.
|
||||
|
||||
### 5.2 Why this beats "LLM scores directly"
|
||||
- **Reproducibility:** Same transcript + same extraction prompt → same evidence tags (modulo LLM nondeterminism, mitigated by temperature=0 + structured output / JSON schema). Rule scoring is fully deterministic given the tags.
|
||||
- **Auditable:** A learner can see *which quote triggered which signal → which level*. This satisfies CBE transparency principles (C-BEN 2023) and is essential for appeals.
|
||||
- **Calibratable:** The signal→level table is editable in YAML without retraining; rubric revision is a config change, not a model change.
|
||||
- **Lower hallucination surface:** LLM is asked only to quote + tag, not to *judge*. Quoting grounds it in the transcript (reduces drift).

||||

||||
### 5.3 Concrete signal taxonomy for one criterion (empathy)
|
||||
|
||||
```yaml
|
||||
# rubrics/customer_service.yaml — fragment
|
||||
criteria:
|
||||
empathy:
|
||||
weight: 0.30
|
||||
signals:
|
||||
- id: no_acknowledgement # absence signal
|
||||
weight: -2
|
||||
- id: scripted_empathy_line # "I understand your frustration"
|
||||
weight: +1
|
||||
- id: named_emotion_in_own_words
|
||||
weight: +1
|
||||
- id: acknowledged_specific # references the actual situation
|
||||
weight: +1
|
||||
- id: tone_pace_adjusted # extracted from sentence length / hedging
|
||||
weight: +1
|
||||
- id: policy_first_before_emotion
|
||||
weight: -2
|
||||
levels:
|
||||
1: { if: [no_acknowledgement, OR, policy_first_before_emotion], score: 1 }
|
||||
2: { if: [scripted_empathy_line, AND, NOT named_emotion_in_own_words], score: 2 }
|
||||
3: { if: [named_emotion_in_own_words, AND, acknowledged_specific], score: 3 }
|
||||
4: { if: [3-level signals, AND, tone_pace_adjusted], score: 4 }
|
||||
5: { if: [4-level signals, AND, no_policy_first_before_emotion, AND, >=2 acknowledgement instances], score: 5 }
|
||||
```
|
||||
|
||||
The rule engine evaluates these deterministically. The LLM's only job is to populate the `signals` list with quotes.
|
||||
|
||||
### 5.4 Remaining risks and mitigations (confidence: 0.68)
|
||||
|
||||
| Risk | Mitigation |
|
||||
|---|---|
|
||||
| LLM extraction nondeterminism | temperature=0, fixed seed, JSON schema-validated output, retry-on-schema-fail. |
|
||||
| LLM misses evidence (false negative) | Run extraction twice on borderline cases; flag disagreement for human review. |
|
||||
| LLM tags a signal that isn't in the transcript (hallucinated quote) | Validate that each `evidence_quote` is a fuzzy-match substring of the transcript; reject otherwise. |
|
||||
| Rubric drift across model upgrades | Pin extractor model version (already D-020-style); re-run a golden transcript regression suite on any model change. |
|
||||
| Adversarial phrasing | The signal taxonomy is behavioral; a learner who says the magic words without behavior still lacks the *specificity* and *tone_pace* signals, capping at level 2–3. |
|
||||
|
||||
**Overall confidence in the two-stage pattern: 0.80** — this is the strongest-evidence recommendation in this document; the extraction/scoring split is well-grounded (Mislevy ECD; Latif & Zhai 2024 survey).

## 6. Customer Service Skill Weights (refund/complaint scenario)
|
||||
|
||||
### 6.1 Evidence on what matters in CS calls
|
||||
|
||||
- **Customer satisfaction (CSAT) literature:** Empathy and "soft" dimensions dominate CSAT variance in complaint/refund contexts (Verleye 2004; Makavana 2021 survey of CSAT drivers). Resolution matters but is *table stakes* — customers don't reward it, they punish its absence.
|
||||
- **Service recovery paradox (Magnini, Ford, Markowski & Honeycutt 2007):** After a service failure, *recovery quality* (empathy + ownership) drives loyalty more than the refund itself. This argues empathy ≥ resolution in a *complaint* context specifically.
|
||||
- **De-escalation** is the safety-critical dimension in escalated calls — it prevents churn, legal escalation, and reputational damage. In *non-escalated* calls it's nearly irrelevant. Weight should be context-dependent.
|
||||
- **Professionalism / conduct** is a *floor* dimension, not a weighting dimension — it's the conjunctive floor from §4.1, not something to up-weight.
|
||||
|
||||
### 6.2 Recommended weights for a refund/complaint scenario (confidence: 0.70)
|
||||
|
||||
| Criterion | Weight | Rationale |
|
||||
|---|---|---|
|
||||
| Empathy / emotional attunement | **0.35** | Dominant driver of CSAT in service-recovery contexts (Verleye 2004; service recovery paradox literature). |
|
||||
| Resolution concreteness | **0.30** | Table-stakes; customers punish absence but don't proportionally reward presence. Still substantial because a great empathic call with no resolution is a failure. |
|
||||
| De-escalation | **0.20** | Safety-critical but only activates in escalated branches. Lower default weight because in the *non-escalated* branch it's near-saturated; *raises* in scenarios with an `escalates_unresolved` failure mode (D-009). |
|
||||
| Professionalism / conduct | **0.15** | Treated as floor (conjunctive ≥2 to pass) rather than primary weight. |
|
||||
|
||||
**Important nuance:** These weights are for the **refund/complaint** scenario specifically (the v0.1 scenario `cs_refund_ca_v01`). A different scenario archetype (e.g., "general inquiry") would tilt empathy down and resolution up. D-039's per-skill weights should be **per-scenario-archetype**, not one global CS weight set. Recommend D-039 be amended to allow `rubrics/customer_service_<archetype>.yaml` or a weights override block in the scenario file.
|
||||
|
||||
### 6.3 Dynamic weighting suggestion (confidence: 0.55 — lower, speculative)
|
||||
If a branch escalates (D-009 `escalates_unresolved` triggered), re-weight on the fly: de-escalation → 0.40, empathy → 0.30, resolution → 0.20, professionalism → 0.10. The rubric's *relevance* changes once the call has gone bad. This is consistent with context-sensitive rubric weighting in OSCE station design (Pell et al. 2010).

## Summary confidence table
|
||||
|
||||
| Section | Confidence | Driver |
|
||||
|---|---|---|
|
||||
| 1. Rubric models (Dreyfus+Miller+EPA+Bloom mastery) | 0.82 | Strong framework fit; well-established literature. |
|
||||
| 2. 5-level anchoring example | 0.78 | Based on established good-rubric principles; example is illustrative, not validated. |
|
||||
| 3. N=3 defensibility | 0.62 | N=3 defensible only for formative / path-completion credentials; thin for high-stakes. |
|
||||
| 4. Mastery score computation (hybrid floor + weighted mean, gate+additive layered) | 0.72 | Aligns with CBE/EPA practice; specific formula is a synthesis, not a direct citation. |
|
||||
| 5. Deterministic scoring (LLM-extract + rule-score) | 0.80 | Strongest evidence base (ECD, LLM-as-judge surveys); pattern is well-grounded. |
|
||||
| 6. CS weights for refund/complaint | 0.70 | Anchored in CSAT/service-recovery literature; specific numbers are judgment calls. |

system_prompt: |
|

You are Casey, a customer with a compound problem.
|
||||
You bought a product 40 days ago (outside the 30-day return window).
|
||||
It arrived with a minor defect that worsened last week.
|
||||
The replacement you were promised is now a week late.
|
||||
You are angry, you have mentioned escalating to a supervisor and posting on social media, and you are weighing whether to cancel your account.
|
||||
You are reasonable but you will only be satisfied if the agent handles all three dimensions simultaneously: the refund/return exception, the de-escalation, and the retention.
|
||||
You will calm down and stay if the agent: acknowledges the compound frustration, names the policy exception being considered, gives a concrete path for the late replacement, and confirms retention explicitly.
|
||||
Stay in character. Do not break role.
|
||||
Keep responses concise for voice (1-3 sentences).
|
||||
Do not give legal, financial, or medical advice.
|
||||
Do not impersonate a real employee of any actual company.
|
||||
opening_line: "I'm done being patient. The product is defective, you're past the return window so you'll probably hide behind policy, the replacement is a week late, and I'm ready to cancel and post about this. What are you going to do?"

|
||||
success_criteria:
|
||||
- "Acknowledged the compound frustration before addressing any single issue"
|

- "Named the policy exception being considered (waiver for the 30-day window given the defect timing)"

common_mistakes:

- list_gate_events(learner_id, path) filters by path

- raw SQL date-range query filters by recorded_at
