# PR #151 - Architecture Review Follow-up

GitHub PR: https://github.com/Mr-DooSun/fastapi-agent-blueprint/pull/151

## Summary

This PR closes the architecture-review follow-up surfaced while synchronising
the hybrid harness documents after PRs #147 through #150. It updates Claude and
shared harness references, clarifies architecture-review expectations for
non-persistence AI domains, and adds explicit admin configuration regression
tests for the `user` and `docs` domains.

The PR is governor-changing because it touches `.claude/rules/**` and
`docs/ai/shared/**`. It therefore records cross-tool review, self-application
proof, and R-point closure here before the draft PR is marked ready.

## Review Rounds

### Round 0 - Sync-Guidelines Review

- **Reviewer**: Codex plus Claude CLI cross-review, read-only for the cross
  review.
- **Target**: shared harness references and Claude project status after recent
  merged governor PRs.
- **Prompt focus**: harness asset inventory drift, Claude project-status drift,
  and whether shared workflow references required synchronisation.
- **Final Verdict**: merge-ready after the update-log fix.
- **Outcome**: `docs/ai/shared/harness-asset-matrix.md` and
  `.claude/rules/project-status.md` were updated. Claude cross-review found the
  missing matrix update-log row; the row was added before commit.

### Round 1 - Architecture Review

- **Reviewer**: Codex plus Claude CLI cross-review, read-only for the cross
  review.
- **Target**: repository architecture surface affected by the sync follow-up.
- **Prompt focus**: test-file expectations, admin configuration coverage, and
  architecture-review checklist drift for non-persistence AI domains.
- **Final Verdict**: merge-ready after follow-up implementation.
- **Findings**:
  - `user` admin configuration lacked a direct admin config regression test.
  - `docs` admin configuration lacked a direct admin config regression test.
  - Shared architecture review guidance was over-broad for non-persistence AI
    domains that use Protocol + Adapter + Selector coverage instead of
    repository persistence coverage.
- **Outcome**: admin config unit tests were added for both domains, and
  `docs/ai/shared/test-files.md` plus
  `docs/ai/shared/architecture-review-checklist.md` were clarified.

### Round 2 - Security Review

- **Reviewer**: Codex plus Claude CLI cross-review, read-only for the cross
  review.
- **Target**: PR diff and related admin security surfaces.
- **Prompt focus**: admin route protection, timing-safe admin auth, sensitive
  field masking, hardcoded secrets, and whether the new tests introduced or
  prevented security risk.
- **Final Verdict**: merge-ready.
- **Findings**:
  - No PR-introduced security issue was found.
  - A pre-existing `docs` admin query UI path displays raw exception strings to
    authenticated admins. This is low severity, not introduced by the PR, and
    does not block the PR.
- **Outcome**: the PR's new tests were confirmed to improve admin
  sensitive-field masking coverage. The pre-existing raw-exception UI note is
  deferred as a follow-up hygiene item.

### Round 3 - PR Quality Gate

- **Reviewer**: Codex `/review-pr`; Claude CLI cross-review, read-only, no
  file modification, no git commands.
- **Target**: PR #151 after adding this review-log entry.
- **Prompt focus**: diff-scope correctness, architecture and security rule
  grounding, drift decision, volatile fact verification, and completion-gate
  closure.
- **Final Verdict**: merge-ready pending CI.
- **Outcome**: no open PR-introduced findings. The shared-doc sync requirement
  is acknowledged and satisfied by Round 0 plus this review-log entry and README
  index update.
- **Claude cross-review notes**:
  - No blocking, high, medium, or low findings.
  - The primary source list should include
    `docs/ai/shared/skills/review-architecture.md` because the PR edits an
    architecture-review checklist source. The file was loaded after the note;
    it delegates category coverage to `architecture-review-checklist.md`, so no
    additional drift was found.
  - This review-log file and the README index update must be committed together
    before the PR is marked ready.

## R-points Closure Table

| Source | R-point | Closure | Note |
|---|---|---|---|
| Round 0 | Harness asset matrix missing the current completion-gate status | Fixed | `docs/ai/shared/harness-asset-matrix.md` now records the current Hybrid Harness v1 state. |
| Round 0 | Claude project status stale after recent governor PRs | Fixed | `.claude/rules/project-status.md` now reflects the current merged PR range and Phase 5 status. |
| Round 0 | Harness matrix update log missing the sync row | Fixed | The update log records the sync follow-up before commit. |
| Round 1 | Missing user admin config regression test | Fixed | `tests/unit/user/interface/admin/test_user_admin_config.py` covers visible columns, generic sensitive masking, explicit password masking, and searchable fields. |
| Round 1 | Missing docs admin config regression test | Fixed | `tests/unit/docs/interface/admin/test_docs_admin_config.py` covers visible columns, sensitive masking defaults, extra query service wiring, and searchable fields. |
| Round 1 | Non-persistence AI domain baseline guidance was over-broad | Fixed | `docs/ai/shared/test-files.md` and `architecture-review-checklist.md` now allow Protocol + Adapter + Selector integration coverage for non-persistence AI domains. |
| Round 1 | Classification container selector direct unit coverage note | Deferred-with-rationale | Existing classification integration coverage remains sufficient for this PR; direct selector unit coverage can be added only if the selector logic changes. |
| Round 2 | No PR-introduced security finding | Rejected | Independent security review and Claude cross-review found no introduced vulnerability in the changed docs or tests. |
| Round 2 | Pre-existing raw exception string in docs admin query UI | Deferred-with-rationale | Low-severity authenticated-admin-only hygiene issue, not introduced by this PR; recommended as a separate follow-up. |
| Round 3 | Shared-doc edits require sync acknowledgement | Fixed | Round 0 ran sync-guidelines-style review; this PR adds the required review-log entry and README index row. |
| Round 3 | PR template required PR-numbered review trail | Fixed | This file is named for PR #151 and is linked from the PR body. |
| Round 3 | Consuming architecture-review skill should be included in the source list | Fixed | `docs/ai/shared/skills/review-architecture.md` was loaded after Claude cross-review; it correctly delegates category coverage to the updated checklist. |
| Round 3 | Review-log file and README index were still local during review | Fixed | The final governor-log commit adds this file and the README index update atomically. |

## Inherited Constraints

- IC-1 through IC-RG-8 from prior governor-changing PRs remain in force.
- The PR follows `docs/ai/shared/governor-paths.md`: `.claude/rules/**` and
  `docs/ai/shared/**` classify this change as governor-changing.
- The doc-only auto-escape is not used. Tier A policy and harness files require
  the normal framing, verification, self-review, cross-tool review, and
  completion-gate path.
- R-point closure uses exactly `Fixed`, `Deferred-with-rationale`, or
  `Rejected`.

## Self-Application Proof

- **Governor-changing scope**: yes. The PR touches `.claude/rules/**` and
  `docs/ai/shared/**`.
- **Sync proof**: Round 0 checked shared harness references and fixed the
  surfaced drift in project status and the harness asset matrix.
- **Architecture proof**: Round 1 identified missing admin config tests and
  over-broad non-persistence AI domain guidance; both were fixed before the
  branch was pushed.
- **Security proof**: Round 2 found no PR-introduced security issue. The only
  note was a pre-existing low-severity admin UI error-message hygiene issue.
- **PR quality gate**: Round 3 applies `/review-pr` to the PR diff and records
  no open PR-introduced findings. Claude gate-on-gate review reported no
  blocking, high, medium, or low findings.
- **Verification**:
  - `uv run pytest tests/unit/user tests/unit/docs tests/integration/classification -q`
    — 26 passed, 1 skipped (`pydantic-ai` optional extra not installed).
  - `uv run ruff check src/` — passed.
  - `python3 tools/check_language_policy.py` — 0 violations.
  - `python3 tools/check_g_closure.py` — 0 violations.
  - `git diff --check` — passed.
