# Phase 07 — architecture-v1-finalization (v1.1.2) Verification

Verifying Phase 07 on `main` (HEAD `8723206`, tag `v1.1.2`). Phase branch
`phase/07-architecture-v1-finalization` deleted after squash merge.

Phase 07 was a **design-authoring phase**: it locked the ACDL architecture
to v1.0 by authoring 9 deliverable files (6 REQ-mapped schema/design
files + the Checkov adapter + the SoD module + the architecture-v1.0
snapshot) that resolve all 11 open decisions in `docs/architecture.md`
§13 (W1.A, W1.B, W2.A, W3.D, W3.E, BA.A, BA.B, BA.C, BA.D, BA.E, BA.F +
the OpenTofu timing sub-decision Q1.3), recorded in `PROJECT.md` under
decisions D-034..D-046.

Verification layers: structural, behavioral, security, quality. All
layers PASS. Final verdict: **Phase 07: VERIFIED**.

## Layer 1 — Structural: PASS

### 1.1 All 9 deliverable files exist

```

-rwxr-xr-x 1 root root  3831 Jul 21 18:48 scripts/verify_phase07.sh
```

All 9 REQ-mapped files + the verify script are present (sizes non-zero).

### 1.2 `docs/architecture-v1.0.md` status line is v1.0 (not v0.2)

```
$ grep -n "Status:" docs/architecture-v1.0.md | head -3
14: Status: **v1.0** (snapshot taken in ACDL Phase 07, milestone v1.1). All 11
429: Status: **v1.0**. All 11 open items in §13 are resolved. ...
```

Status line at L14 says `v1.0` (Phase 07 bump); the upstream `v0.2`
status does not survive into the snapshot's status line.

### 1.3 All 11 open-decision IDs + Q1.3 appear in the snapshot

```
$ grep -cE "W1\.A|W1\.B|W2\.A|W3\.D|W3\.E|BA\.A|BA\.B|BA\.C|BA\.D|BA\.E|BA\.F|Q1\.3" \
    docs/architecture-v1.0.md
33
```

Every one of the 11 IDs + Q1.3 appears in both the resolution log table
(L26–37) and the §13 "✅ RESOLVED (see PROJECT.md)" markers (L75–425).
Each row carries the resolution text + a pointer to `PROJECT.md`.

### 1.4 `gitea-runner` rename (D-046) applied; `act_runner` only in "formerly" note

```
$ grep -n "act_runner\|gitea-runner" docs/architecture-v1.0.md
9:    > `act_runner` → `gitea-runner` rename (D-046, 2026-04 in gitea/runner#850)
10:   > is applied; `act_runner` appears only in a "formerly" note.
352:  > gitea-runner v2.1.0 (formerly `act_runner`, renamed 2026-04 in
```

`gitea-runner` is the body name; `act_runner` only appears in the
header note + the "formerly" parenthetical at L352. D-046 satisfied.

### 1.5 §15 table lists all 6 REQ-mapped files

```
$ sed -n '441,455p' docs/architecture-v1.0.md
## 15. Phase 07 authored artifacts
...
| REQ | File | Owner persona |
|-----|------|--------------|
| REQ-17 | `schemas/ir.schema.json` | platform-engineer |
| REQ-18 | `schemas/policy_check_result.schema.json` + `adapters/terraform/policy/checkov_adapter.py` | security-engineer |
| REQ-19 | `platform/confidence_signal.py` | backend-engineer + security-engineer (co-authored) |
| REQ-20 | `platform/audit_ledger_design.md` | security-engineer |
| REQ-21 | `platform/hitl_matrix_design.md` + `platform/separation_of_duties.py` | security-engineer |
| REQ-22 | `schemas/contract.schema.json` | backend-engineer |
```

All 6 REQ rows + the 8 underlying files are listed. All §15 files
exist on disk (cross-checked with `os.path.exists` for every entry).

### 1.6 The 3 JSON Schemas declare Draft 2020-12 + required fields

```
$ grep -n '\$schema\|draft/2020-12' schemas/*.schema.json
schemas/ir.schema.json:2:                  "$schema": "https://json-schema.org/draft/2020-12/schema",
schemas/policy_check_result.schema.json:2: "$schema": "https://json-schema.org/draft/2020-12/schema",
schemas/contract.schema.json:2:             "$schema": "https://json-schema.org/draft/2020-12/schema",
```

Per-file required-fields check:

- `schemas/ir.schema.json`: `required: [version, stack, resources]`;
  `stack.depth` max 5; `stack.name` pattern `^l[12]-[a-z][a-z0-9-]*$`;
  `stack.kind` enum `[l1, l2]`; `resource.module` pattern
  `^l1-[a-z][a-z0-9-]*@\d+\.\d+\.\d+$` (W3.D name@semver); `relationship.kind`
  enum `[parent, depends_on, uses_output]`; `shared_keyword` reserved
  (present, unused). ✅
- `schemas/policy_check_result.schema.json`: `required: [contractId,
  evaluatedAt, engine, ruleId, severity, result, message, resourceRef]`;
  `engine` enum `[checkov, kyverno, opa]`; `severity` enum `[critical,
  high, medium, low, info]`; `result` enum `[pass, fail, skipped, error]`;
  `evidence` optional with `additionalProperties: true`. ✅
- `schemas/contract.schema.json`: top `required: [stack, environment]`;
  `stack` pattern `^l2-[a-z][a-z0-9-]*$`; `environment` enum `[dev, qa,
  prod, dr]` (no `staging`); `profile` enum `[developer, agentic]`
  default `developer`; `allOf` conditionals present: qa→`[validation]`,
  prod→`[runbook, dashboard, oncall]`, dr→`[drDrillRef]`,
  agentic→`[naturalLanguageIntent]`. ✅

Substrate-agnostic invariant for IR schema: the only occurrence of
`aws_s3_bucket` is in the `$comment` (L6) and a `description` (L61)
where it is explicitly called out as the *non*-IR / *Terraform* type to
avoid. No Terraform-block keywords (`variable`/`output` as JSON keys,
`tf_block`) appear in the schema body. Invariant satisfied.

### 1.7 The 3 .py files have expected module docstrings + public functions

- `platform/confidence_signal.py` (REQ-19, T-7.9): module docstring
  (L1–32) enumerates the 6 inputs + weights + severity→penalty +
  per-env thresholds. Public surface: `WEIGHTS`, `PENALTY`,
  `THRESHOLDS`, `Signal` dataclass, `_per_input_score`, `compute`,
  `__main__` CLI. ✅
- `platform/separation_of_duties.py` (REQ-21, T-7.8): module docstring
  (L1–12) explains `qaApprover != prodApprover` + outbox read + spike
  dev-only note. Public surface: `check(outbox_client, contract_id,
  current_prod_approver)`, `route_halt_artifact(...)`. ✅
- `adapters/terraform/policy/checkov_adapter.py` (REQ-18, T-7.5): module
  docstring (L1–11) "Translate Checkov JSON output to ACDL
  PolicyCheckResult records". Public surface: `RULE_MAP`,
  `_iso8601_now`, `_to_pcr`, `_emit_tag_naming_skipped`, `adapt`,
  `__main__` CLI. ✅

### 1.8 History preservation — `docs/architecture-v1.0.md` is a new file

```
$ git log --follow --oneline docs/architecture-v1.0.md
92d4535 phase: 7, status: plan-as-execute, persona: lead-developer, task: T-7.1
```

Single creation commit (T-7.1, 92d4535). As expected for a new file —
the upstream `docs/architecture.md` (52665b8 → b84a8a2) history is
preserved on the upstream file itself; the snapshot is intentionally a
new file, not a copy-with-rename.

### 1.9 Tags v1.1.0, v1.1.1, v1.1.2 all exist

```
$ git tag --list 'v1.1*'
v1.1.0
v1.1.1
v1.1.2
```

## Layer 2 — Behavioral: PASS

### 2.1 `scripts/verify_phase07.sh` exits 0 with the expected final line

```
$ bash scripts/verify_phase07.sh
ok: all 9 deliverable files exist
ok: 3 JSON Schemas validate as Draft 2020-12
ok: 3 .py files py_compile
ok: 3 .md design files non-empty
ok: all 11 decision IDs + OpenTofu present in PROJECT.md
ok: docs/architecture-v1.0.md status is v1.0
ok: D-040..D-044 present in PROJECT.md
ok: spike contract validates against contract schema
ok: minimal IR validates against IR schema
VERIFIED — Phase 07: architecture v1.0 finalized; 6 files authored + 11 decisions resolved

$ echo $?
0
```

All 9 assertions in the script pass; final line matches PLAN.md spec.

### 2.2 Typecheck gate

```
$ bash -n scripts/verify_phase07.sh && \
    python3 -m py_compile platform/confidence_signal.py \
                          platform/separation_of_duties.py \
                          adapters/terraform/policy/checkov_adapter.py
TYPECHECK_OK
```

`bash -n` (syntax) + `py_compile` (byte-compile) all pass.

### 2.3 Schema cross-checks (PLAN.md self-verify test instances)

Run from `/tmp` to avoid the repo `platform/` package shadowing stdlib
`platform` (see Layer 3 §3.3):

```
OK: qa without validation fails
OK: prod without runbook fails
OK: dr without drDrillRef fails
OK: agentic without NLI fails
OK: agentic with NLI passes
OK: staging rejected
OK: valid PCR passes
ALL_SCHEMA_CROSSCHECKS_OK
```

`environment` enum confirmed `[dev, qa, prod, dr]` — no `staging`
(Path A locked, ARCHITECTURE.md §5). Per-env mandatory conditionals all
fire correctly.

### 2.4 Confidence signal behavioral spot-checks (REQ-19)

Run from `/tmp` with `sys.path.insert(0, '/root/acdl')`:

- **Missing input → block + INPUT_MISSING:** `compute('cid','dev', inputs)`
  with `nfrs` omitted returns `Signal(0.0, "block", {}, ["INPUT_MISSING:nfrs"])`. ✅
- **Critical fail → 0.0 block + CRITICAL_OVERRIDE:** `compute('cid','dev', inputs)`
  with one `severity:"critical", result:"fail"` PolicyCheckResult returns
  `Signal(0.0, "block", per_input, ["CRITICAL_OVERRIDE:CKV_AWS_X"])`
  regardless of other inputs. ✅
- **Cold-start dev → pass ≥ 0.50:** `compute('cid','dev', inputs)` with
  the ACDL_TAG_NAMING `skipped` PolicyCheckResult + all validation true
  + neutral 0.5 for freshness/source/history/nfrs returns
  `Signal(0.950, "pass", ...)`. ✅ (0.95 ≥ 0.50 dev threshold).

Note: the `WEIGHTS` dict keys are `policy / validation / freshness /
source / history / nfrs` (the canonical names), not the docstring's
`policy_results` label — the docstring describes the input's *type*
("list[PolicyCheckResult]"); the `compute()` loop iterates
`WEIGHTS.items()` and reads `inputs.get("policy")` (the key). This is
consistent with the Wave 4 self-verify ("`policy_results`" in the
docstring is the descriptive label, `policy` is the dict key — verified
at runtime).

### 2.5 Separation-of-duties behavioral spot-checks (REQ-21)

- `check(None, "cid", "anyone")` → `(True, "no outbox client (dev-only spike)")`. ✅
- `check(stub_returning_None, "cid", "anyone")` → `(True, "no prior approver (first promotion)")`. ✅
- `check(stub_with_approver_qa("alice"), "cid", "alice")` → `(False, "SEPARATION_OF_DUTIES_VIOLATION: qaApprover==prodApprover==alice")`. ✅
- `check(stub_with_approver_qa("alice"), "cid", "bob")` → `(True, "distinct")`. ✅
- `check(stub_with_empty_approver_qa, "cid", "alice")` → `(True, "no QA approver recorded (dev-only spike)")`. ✅

All SoD branches match PLAN.md T-7.8 spec.

### 2.6 Checkov adapter behavioral spot-check (REQ-18 adapter)

Synthetic Checkov JSON with one failed `CKV_AWS_24`:

```
$ python3 adapters/terraform/policy/checkov_adapter.py fixture.json test-contract-id
[
  {
    "contractId": "test-contract-id",
    "evaluatedAt": "2026-07-21T18:49:11Z",
    "engine": "checkov",
    "ruleId": "CKV_AWS_24",
    "severity": "medium",        ← per RULE_MAP (public-ingress SG 0.0.0.0/0)
    "result": "fail",
    "message": "SG 0.0.0.0/0 on 22",
    "evidence": {"file_path": null, "resource": "aws_security_group.r1",
                 "resource_address": "aws_security_group.r1", "code_block": null},
    "resourceRef": "aws_security_group.r1"
  },
  {
    "contractId": "test-contract-id",
    "ruleId": "ACDL_TAG_NAMING",   ← D-043 appended SKIPPED record
    "severity": "info",
    "result": "skipped",
    "message": "tag/naming check deferred to v1.2 (D-043)",
    "evidence": {},
    "resourceRef": ""
  }
]
```

Severity correctly defaulted to `medium` for `CKV_AWS_24` from `RULE_MAP`;
`ACDL_TAG_NAMING` SKIPPED record appended (D-043). Both records validate
against `schemas/policy_check_result.schema.json`.

## Layer 3 — Security: PASS

### 3.1 No credentials/secrets introduced

Files touched by Phase 07 (v1.1.1..v1.1.2):

```
$ git log v1.1.1..v1.1.2 --diff-filter=A --name-only --pretty=format: | sort -u
.ciagent/PLAN.md
.ciagent/REQUIREMENTS.md
.ciagent/ROADMAP.md
.ciagent/VERIFY.md
adapters/terraform/policy/__init__.py
adapters/terraform/policy/checkov_adapter.py
docs/architecture-v1.0.md
platform/__init__.py
platform/audit_ledger_design.md
platform/confidence_signal.py
platform/hitl_matrix_design.md
platform/separation_of_duties.py
schemas/contract.schema.json
schemas/ir.schema.json
schemas/policy_check_result.schema.json
scripts/verify_phase07.sh
```

No `.env`, no `*.tfstate`, no `*_key*`, no `credentials*` files. Phase 07
is design authoring + stdlib-only Python — no AWS/TF runtime calls, no
boto3 imports (the spike passes a duck-typed `outbox_client`).

### 3.2 LSP diagnostic on `platform/confidence_signal.py:148` is a false positive

```
$ python3 -m py_compile platform/confidence_signal.py
$ python3 -c "import ast; ast.parse(open('platform/confidence_signal.py').read()); print('AST parse OK')"
AST parse OK
```

At L148, `p = PENALTY.get(sev, 0.0)` — `sev` comes from
`pcr.get("severity")` where `pcr` is `Dict[str, Any]`. The LSP
("No overloads for `get` match the provided arguments") is a known
false-positive when `.get()` is called on a `Dict[str, Any]` value
in some pyright configurations. `py_compile` passes; runtime behavior
is verified correct in §2.4 (the critical-override branch returns the
expected `CRITICAL_OVERRIDE:<ruleId>` and the `None` sentinel correctly
short-circuits via `if p is None:` at L149). Not a real bug.

### 3.3 `platform/` package shadows stdlib `platform` — documented + worked around

The repo's `platform/` Python package (our code) shadows the stdlib
`platform` module when the repo root is on `sys.path[0]` (which a
`python3 -c` invocation from repo root triggers). `jsonschema` imports
`uuid` → `uuid` imports `platform.system()` → fails with
`AttributeError: module 'platform' has no attribute 'system'`.

`scripts/verify_phase07.sh` documents this and works around it by
running all `jsonschema`-invoking python from `/tmp` with absolute
paths to the schemas:

```
$ grep -n "platform\|cd /tmp\|sys.path\|shadow" scripts/verify_phase07.sh
24: # Run python from /tmp so the repo's `platform/` package does not shadow the
25: # stdlib `platform` module (jsonschema imports uuid -> platform.system();
26: # our platform/ shadows it when cwd is repo root and on sys.path[0]).
28:   ( cd /tmp && python3 -c "..." )
70:   ( cd /tmp && python3 -c "..." )
78:   ( cd /tmp && python3 -c "..." )
```

The workaround is correct: `cwd=/tmp` puts `/tmp` at `sys.path[0]`, so
`import platform` resolves to the stdlib, not our package; the schemas
are passed by absolute path. The verify script passes (§2.1), and my
inline behavioral spot-checks (§2.3–2.5) reproduced the workaround by
running from `/tmp` + `sys.path.insert(0, '/root/acdl')` to import our
modules explicitly.

**P1 — flag for post-hoc cleanup:** a v1.2 rename of `platform/` to
`acdl_platform/` (or moving the package under a `src/` layout) would
avoid the shadowing entirely, removing the need for the `/tmp` dance in
every jsonschema-invoking test. This is out of Phase 07 scope (Phase 07
must ship the `platform/` layout the README + PLAN.md committed to).
Flagged for v1.2.

### 3.4 No `import boto3` in the Phase 07 .py files

```
$ grep -nE "^import |^from " platform/confidence_signal.py \
                          platform/separation_of_duties.py \
                          adapters/terraform/policy/checkov_adapter.py
platform/confidence_signal.py:34: from dataclasses import dataclass, asdict
platform/confidence_signal.py:35: from typing import List, Literal, Optional, Dict, Any
platform/confidence_signal.py:36: import json
platform/confidence_signal.py:37: import sys
platform/separation_of_duties.py:14: from typing import Optional, Tuple
adapters/terraform/policy/checkov_adapter.py:13: import datetime
adapters/terraform/policy/checkov_adapter.py:14: import json
adapters/terraform/policy/checkov_adapter.py:15: import sys
```

Stdlib only across all 3 modules. The SoD `check()` signature receives
a duck-typed `outbox_client` (has `.get(pk)`); the pipeline step owns the
boto3 client. PLAN.md T-7.8 spec satisfied.

## Layer 4 — Quality: PASS

### 4.1 README layout table still matches reality

```
$ grep -n "platform/\|schemas/\|adapters/" README.md
31: | `platform/` | Platform code: confidence signal, contract resolver, outbox, HITL/ledger designs | Phase 07+ |
32: | `schemas/`  | JSON Schemas: IR, PolicyCheckResult, contract | Phase 07 |
33: | `adapters/` | Substrate adapters (Terraform adapter in v1; the only substrate-specific code per §12) | Phase 09 |
```

README's "Phase 07+" and "Phase 07" annotations are now accurate —
`platform/` and `schemas/` are populated with the 9 deliverable files
(no longer just `.gitkeep`'d). `adapters/` is annotated "Phase 09"
which is also accurate: only the `policy/` subdirectory is populated in
Phase 07 (the Checkov adapter, REQ-18), and the rest of the adapter
surface (the IR→Terraform module compiler) is Phase 09.

### 4.2 Phase 07 commit messages all carry `---ci---` blocks

Phase 07 commits on main (v1.1.1..v1.1.2):

```
8723206  ship: phase-07 architecture-v1-finalization (v1.1.2)
412e1ef  phase: 7, status: plan-as-execute, persona: lead-developer, task: T-7.10
68d90c0  phase: 7, status: plan-as-execute, persona: backend-engineer+security-engineer, task: T-7.9
6ed93f0  phase: 7, status: plan-as-execute, persona: security-engineer, task: T-7.4..T-7.8
f8e99ed  phase: 7, status: plan-as-execute, persona: platform-engineer+backend-engineer, task: T-7.2+T-7.3
92d4535  phase: 7, status: plan-as-execute, persona: lead-developer, task: T-7.1
b40aadd  docs(P07): create Phase 07 plan (architecture-v1-finalization)
```

Each execute commit + the ship commit carries a `---ci---` block with
`project / phase / milestone / status / persona / task` (execute commits)
or `release.tag` (ship commit). Verified by inspecting commit bodies
(`git log v1.1.1..v1.1.2 --pretty=format:'%H %s%n---%n%b%n---'`):
T-7.1, T-7.2+7.3, T-7.4..7.8, T-7.9, T-7.10, and the merge all include
well-formed `---ci---` blocks. ✅

### 4.3 `ROADMAP.md` Phase 07 status = "complete (v1.1.2)"

```
$ grep -n "Phase 07\|complete.*v1.1.2\|status" .ciagent/ROADMAP.md | head -5
91: ### Phase 07 — architecture-v1-finalization
93: - **Status:** complete (v1.1.2)
```

### 4.4 `REQUIREMENTS.md` traceability — REQ-16..22 complete (v1.1.2)

```
$ grep -n "REQ-1[6-9]\|REQ-2[0-2]" .ciagent/REQUIREMENTS.md | tail -7
117: | REQ-16 | 07 | complete (v1.1.2) |
118: | REQ-17 | 07 | complete (v1.1.2) |
119: | REQ-18 | 07 | complete (v1.1.2) |
120: | REQ-19 | 07 | complete (v1.1.2) |
121: | REQ-20 | 07 | complete (v1.1.2) |
122: | REQ-21 | 07 | complete (v1.1.2) |
123: | REQ-22 | 07 | complete (v1.1.2) |
```

All 7 Phase 07 requirements marked complete at v1.1.2.

### 4.5 `docs/architecture-v1.0.md` internal consistency

- The §15 table's 6 files (8 underlying paths) all exist on disk
  (verified via `os.path.exists` for every entry). ✅
- The 11 resolutions in the §13 markers (L75–425) match the
  `PROJECT.md` "Open-decision resolutions" table (L178–189) verbatim
  (W1.A, W1.B, W2.A, W3.D, W3.E, BA.A, BA.B, BA.C, BA.D, BA.E, BA.F) +
  the Q1.3-OpenTofu sub-decision. ✅
- Decisions D-034..D-046 all present in `PROJECT.md` (the decision
  table at L160–172). ✅

## Issues found

### P0 (blocking) — none

No P0 issues. All must-haves from PLAN.md are satisfied; the phase gate
`scripts/verify_phase07.sh` is green; behavioral spot-checks all pass.

### P1 (post-hoc cleanup, out of Phase 07 scope)

- **P1-1: `platform/` package shadows stdlib `platform`.** The repo's
  `platform/` directory is a Python package that shadows the stdlib
  `platform` module when the repo root is on `sys.path` (any `python3 -c`
  from repo root). This breaks `jsonschema` (which imports `uuid` →
  `platform.system()`). `scripts/verify_phase07.sh` works around it by
  running jsonschema-invoking python from `/tmp`, but the workaround is
  brittle — every future test script that imports `jsonschema` (or any
  stdlib module that transitively imports `platform`) from repo root
  will hit the same shadow. Recommended v1.2 fix: rename `platform/` →
  `acdl_platform/` (or adopt a `src/` layout) so the package no longer
  collides with the stdlib name. Out of Phase 07 scope (the layout is
  locked by Phase 06 + README + PLAN.md).

- **P1-2: LSP false positive on `platform/confidence_signal.py:148`.**
  The "No overloads for `get` match the provided arguments" diagnostic
  is a pyright false positive triggered by `Dict[str, Any]` typing on
  `pcr`. `py_compile` passes; runtime behavior is correct (verified in
  §2.4). No fix needed in Phase 07; if a v1.2 type tightening pass
  happens, replacing `Dict[str, Any]` with a `TypedDict` for
  `PolicyCheckResult` would silence the LSP and improve type safety.

## Requirement coverage summary
