Anyone who can reach the Pipecat server's `/pipecat/webrtc` endpoint could start a session. | Low (pilot) | **Accept** | D-007 explicitly defers auth. Single-learner harness; the server binds `0.0.0.0:8789` but is intended for a single pilot host. CORS is `allow_origins=["*"]` (dev) — acceptable for v0.1, **flag for tightening before any multi-learner milestone** (P1). | +| **Tampering** | SQLite local file (`praxis.db`) — no integrity protection. A local user can `sqlite3 praxis.db` and edit session/outcome/cost rows. | Low (pilot) | **Accept** | D-007: local pilot, single-learner. Trust model assumes the pilot host is trusted. No tamper-evidence needed for tech-validation. Documented in `db/schema.sql` header. | +| **Repudiation** | Sessions are logged with auto-generated ids (`sess-`) and timestamps; no signed audit trail. A learner could dispute "I never did that session." | N/A (pilot) | **Accept** | Single hardcoded learner, no auth → no multi-party repudiation surface. Sessions are for learner self-review, not compliance. | +| **Info Disclosure** | (a) `.ciagent/.env.secrets` is `0600` perms + gitignored — ✅ verified. (b) `.env`, `.env.secrets`, `.env.*` all in `.gitignore` — ✅ verified. (c) `git ls-files` confirms **no secret/key/db files tracked**. (d) Grep for hardcoded API keys (`sk-...`, `*_API_KEY="..."` assignments) → **0 matches** in non-example files. (e) `db/*.db` gitignored — no learner data leaked. | Low | **Accept** | Secrets handling is correct. The local `.ciagent/.env.secrets` contains a `DEEPGRAM_API_KEY` value (40 chars) but it is **not committed** (gitignored, 0600) — this is the intended dev-secret pattern. No info-disclosure vulnerability found. | +| **Denial of Service** | No rate limiting on the FastAPI/Pipecat server; no connection cap; a client can open many WebRTC sessions. `asyncio.create_task(runner.run(task))` fires-and-forgets per request. | Low-Medium (pilot) | **Accept (v0.1) / Flag (P1)** | D-007/D-012: single-learner pilot, no adversarial threat model. Acceptable for v0.1. **Flag for P1 post-hoc review**: before any multi-learner exposure, add connection limits + task lifecycle management (the current `create_task` without tracking could leak tasks on disconnect). | +| **Elevation of Privilege** | No auth → no privilege ladder → no escalation surface. | N/A | **Accept** | N/A for v0.1. | + +### Injection-vector review (security persona) + +| Vector | Status | Evidence | +|---|---|---| +| **YAML scenario loading** | ✅ Safe | `server/scenarios/loader.py` uses `yaml.safe_load` (not `yaml.load`) — no arbitrary Python object construction. Scenario files are repo-authored (D-007: no user-uploaded scenarios in v0.1). | +| **LLM prompt construction** | ✅ Contained | `classifier.py::_build_user_prompt` and `debrief.py::_render` interpolate learner text into the prompt via string replacement. A malicious learner ASR transcript could inject prompt text, but: (a) the LLM is role-playing a customer (no tool calls / no DB writes from LLM output), (b) the guardrail output filter runs on the response, (c) the branch classifier output is JSON-parsed leniently with fallback. Prompt injection impact is bounded to a misclassified branch or a weird debrief — not a security boundary for v0.1. **Accept.** | +| **SQL injection** | ✅ Safe | `db/store.py` uses parameterized queries exclusively (`?` placeholders) — no string-interpolated SQL. | +| **Path traversal (scenario id)** | Low | `loader.load(scenario_id)` builds `base / f"{scenario_id}.yaml"` — a `scenario_id` containing `../` could escape `scenarios/`. In v0.1 the id comes from the env var `PRAXIS_SCENARIO` (operator-controlled), not user input. **Accept for v0.1; flag for P1** if scenario ids ever become user-selectable. | + +**Layer 3 verdict: ACCEPT.** No high-severity STRIDE findings. 3 P1 flags for future hardening (CORS tightening, DoS/connection limits, path-traversal guard) — all appropriate for a post-pilot milestone, not v0.1 blockers. + +--- + +## Layer 4 — Quality (multi-persona review) + +### P0 fixes applied (2) + +Both are risk-free cosmetic cleanups with no logic/behavior change.

Worked at runtime only because the method references the constant by the same misspelled name and Python resolves globals at call time — but the typo is a latent trap: any future refactor that renames one occurrence would silently break the debrief filter, causing legal-action recommendations to pass unfiltered (a safety regression). | Renamed both occurrences to `_DEBRIEF_LEGAL_REDIRECT`. | `test_debrief_guardrail_blocks_legal_action` passes; manual end-to-end check confirms legal-action text still replaced by the redirect. | +| P0-2 | `server/debrief.py:31` | Dead code: `rel = template_id.replace("/", ".") ...` computed but never used (the actual path resolution uses `template_id.split('/')[-1]`).

Runtime is fine; static analysis is noisy. | Add `# type: ignore[...]` annotations with reasons, or wrap Pipecat service construction in typed helper functions. Register test fakes via `LLMProvider.register` or duck-type with `Protocol`. Non-blocking. | +| Q-2 | P1 | Correctness | `server/latency.py:106-112` | `TextFrame` is treated as an LLM-first-token proxy, but `TextFrame` is generic — it can carry non-LLM text (e.g. the opening-line TTS input), which could misattribute the first-token timestamp. The `LLMFullResponseEndFrame` branch (L99) is a better proxy but also imperfect. | For v0.1 accept (latency is logged, not enforced); for Phase 2 use Pipecat's `LLMTokenUsageFrame` / metrics service for accurate TTFT. | +| Q-3 | P1 | Adversarial/Security | `server/scenarios/loader.py:34` | `load(scenario_id)` builds `base / f"{scenario_id}.yaml"` without sanitizing `../` — path traversal possible if `scenario_id` is ever user-controlled. Currently env-var-controlled (operator), so low risk. | Add a guard: reject `scenario_id` containing path separators or `..`, or resolve + verify the result stays within `base`. | +| Q-4 | P1 | Security/DoS | `server/__main__.py:96-98` | `asyncio.create_task(runner.run(task))` is fire-and-forget — no tracking of running tasks, no cap on concurrent sessions, no cancellation on client disconnect. Acceptable for single-learner pilot but would leak resources at scale. | Track tasks in a set; cancel on disconnect; cap concurrency. Defer to multi-learner milestone. | +| Q-5 | P1 | Security | `server/__main__.py:55` | CORS `allow_origins=["*"]` — dev setting. Acceptable for v0.1 single-origin pilot but must be tightened before any non-local exposure. | Make CORS origin env-configurable (`PRAXIS_CORS_ORIGINS`); default to the client dev origin. | +| Q-6 | P2 | Testing | `tests/test_e2e.py:16-37` | The 3 e2e test functions each call `asyncio.run(run_e2e(...))` independently — the full loop runs 3× per test session (wasteful, ~3× the DB writes). Also `test_e2e_debrief_non_empty` re-runs the whole loop just to assert `debrief_chars > 50`. | Refactor to a session-scoped fixture that runs `run_e2e` once and shares the result dict across the 3 assertions. Non-blocking. | + +### Per-persona summary + +**Correctness:** Logic is sound across the hot path. `classify_branch_sync_heuristic` correctly scores branches by signal-keyword overlap and tie-breaks to the first branch (deterministic). `derive_cost` arithmetic verified (`test_derive_cost_piper_zero_tts` confirms Piper $0 path). `LatencyRecord.e2e_asr_to_tts_ms` math correct (550ms in test). Branch classifier parser is lenient (handles code fences, malformed JSON, empty input) with safe fallbacks. **No correctness P0s.** + +**Testing:** 73 tests are meaningful — they cover schema validation, adapter graceful degradation, guardrail block categories, cost math, store CRUD, recorder lifecycle, debrief generation/filter, latency math, and the full e2e loop with DB assertions. Coverage is broad; gaps are the live-key paths (now covered by `test_pending_keys.py` skips) and client-side (no React component tests — v0.1 relies on e2e smoke per `package.json` "test" script). The `_FakeLLM`/`_StubDebriefLLM` fakes structurally satisfy the `LLMProvider` contract. **No testing P0s.** One P2 (test redundancy, Q-6). + +**Security:** See Layer 3. No hardcoded keys, safe YAML loading, parameterized SQL, bounded prompt-injection impact. 3 future-hardening P1s (Q-3/4/5). **No security P0s.** + +**Performance:** No O(n²) in the voice-loop hot path. `LatencyObserver.process_frame` is O(1) per frame (passes through + records a timestamp). `lru_cache` on registry getters avoids repeated adapter construction. `SessionRecorder.log_turn` is O(1) per turn. The classifier runs once at session end (D-P1-05 — offline from the latency path). **No performance P0s.** One observation: `LLMContextAggregator` + Pipecat's context object grow with conversation length (unbounded turn history) — acceptable for v0.1 short sessions; flag for Phase 2 if sessions exceed ~50 turns. + +**Maintainability:** Interfaces (`TTSProvider`/`LLMProvider`/`Guardrail`) are clean ABCs with typed dataclasses (`TTSResult`, `LLMStreamChunk`, `GuardrailVerdict`, `GuardrailContext`). The registry centralizes env-based selection. Adapters are thin and consistently degrade gracefully on missing keys/models. Naming is clear. The one maintainability defect was the `_DEBRIFF` typo (fixed as P0-1).
