# PR #152 — CRUD Data Validation Sync

## Summary

PR #152 ([GitHub PR](https://github.com/Mr-DooSun/fastapi-agent-blueprint/pull/152)) implements issue #10 CRUD data validation for RDB writes. The code change added Service-owned validation hooks, reusable core validation helpers, repository read primitives for validation, User username/email uniqueness enforcement, DB unique constraints, and targeted tests. The follow-up `/sync-guidelines` pass updates shared references so future agents see the new BaseService and BaseRepositoryProtocol surfaces.

## Review Rounds

### Round 1 — Implementation Review Drift Signal

- **Target:** issue #10 implementation diff before shared-doc sync.
- **Prompt focus:** architecture/security correctness, User uniqueness semantics, DB conflict translation, and whether shared docs drifted.
- **Surfaced points:**
  - **R1.1:** `docs/ai/shared/project-dna.md` still described the old `BaseRepositoryProtocol` and `BaseService` method surface.
  - **R1.2:** `docs/ai/shared/scaffolding-layers.md` still showed the old repository protocol skeleton and did not mention Service validation hooks.
  - **R1.3:** Skill guidance might over-expand if endpoint skills were updated for Service-internal validation.
- **Final Verdict:** implementation can proceed, but Sync Required is true.

### Round 2 — Claude `/sync-guidelines` Scope Challenge

- **Reviewer:** Claude Opus, xhigh effort, no-tools summary review after read-tool mode was unavailable.
- **Target:** proposed `/sync-guidelines` closure plan for PR #152.
- **Prompt focus:** challenge whether the sync scope was too broad and whether governor artefacts were required.
- **Surfaced points:**
  - **R2.1:** Verify `project-dna.md` before editing; do not assume drift.
  - **R2.2:** `scaffolding-layers.md` is the highest-confidence drift because future domains copy it.
  - **R2.3:** Reject broad `add-api` wrapper edits; validation hooks are Service lifecycle, not endpoint authoring.
  - **R2.4:** Avoid duplicating rule details in `.claude/rules/architecture-conventions.md`; keep rule details canonical.
  - **R2.5:** Add the upstream AGENTS.md hook section if validation hooks are a shared rule.
  - **R2.6:** Check whether ADR 043 needs a protocol addendum.
  - **R2.7:** If any Tier A file lands, add governor-review-log and PR Governor section.
- **Final Verdict:** sync required, but keep scope narrow.

### Round 3 — Claude Gate-on-Gate Review

- **Reviewer:** Claude Opus, xhigh effort, no-tools summary review after the sync patch.
- **Target:** applied `/sync-guidelines` result for PR #152.
- **Prompt focus:** missed drift, overreach, governor artefacts, and whether Sync Required remains true.
- **Surfaced points:**
  - **R3.1:** Requiring a new ADR for the validation hook pattern would be overreach while the hooks are additive and no-op by default.
  - **R3.2:** Leaving `add-api` and wrappers unchanged is correct because endpoint authoring should not duplicate Service lifecycle guidance.
  - **R3.3:** Generic validation-hook test pattern documentation can wait until a second domain adopts hook overrides.
- **Final Verdict:** approved; Sync Required is false after this pass.

## Inherited Constraints

- AGENTS.md § Language Policy: all new Tier 1 prose is English-only; no hidden Korean rationale.
- AGENTS.md § Default Coding Flow: Tier A/B/C changes require cross-tool review and a governor-review-log entry.
- AGENTS.md guard G: every cross-review point must close as `Fixed`, `Deferred-with-rationale`, or `Rejected`.
- `docs/ai/shared/governor-paths.md`: `docs/ai/shared/**`, `AGENTS.md`, and `.claude/**` make this PR governor-changing.

## Self-Application Proof

### `/review-pr` Equivalent

- **Findings:** no blocking code/security finding remained after update unique conflict translation was added.
- **Drift Candidates:** `project-dna.md`, `scaffolding-layers.md`, Service validation guidance, and governor artefacts.
- **Sync Required:** true.

### `/sync-guidelines` Equivalent

- **Mode:** review follow-up.
- **Input Drift Candidates:** consumed from `/review-pr` and Claude Round 2.
- **project-dna:** updated for `Protocol`, repository validation primitives, and BaseService validation hooks.
- **AUTO-FIX:** AGENTS.md CRUD write validation rule, `project-dna.md`, `scaffolding-layers.md`, Claude rule sync (`architecture-conventions.md`, `project-status.md`, reviewed timestamps for overview/commands), governor-review-log entry, README index.
- **REVIEW:** generic validation-hook test-pattern documentation is deferred until another domain adopts hook overrides.
- **Remaining:** none for current shared guideline drift after verification.
- **Next Actions:** keep PR #152 Governor-Changing PR section filled and re-run pre-commit.

## R-points Closure Table

| Source | R-point | Closure | Note |
|---|---|---|---|
| Round 1 | R1.1: `project-dna.md` stale BaseRepositoryProtocol/BaseService surface | Fixed | Verified live stale method tables and updated them. |
| Round 1 | R1.2: `scaffolding-layers.md` stale protocol skeleton and missing validation hook guidance | Fixed | Updated repository protocol example and Service validation hook guidance. |
| Round 1 | R1.3: endpoint skill guidance could over-expand | Rejected | `add-api` stayed unchanged because validation hooks are Service lifecycle, not endpoint authoring. |
| Round 2 | R2.1: verify `project-dna.md` before editing | Fixed | Verified stale `Generic` example and missing primitive rows before patching. |
| Round 2 | R2.2: update `scaffolding-layers.md` narrowly | Fixed | Applied targeted scaffold guidance only. |
| Round 2 | R2.3: reject broad `add-api` wrapper edits | Rejected | No `add-api` shared or wrapper files were changed. |
| Round 2 | R2.4: avoid duplicating validation rule details in Claude rules | Fixed | `.claude/rules/architecture-conventions.md` now contains only a one-line pointer to AGENTS.md. |
| Round 2 | R2.5: add upstream AGENTS.md hook section | Fixed | Added AGENTS.md § CRUD Write Validation. |
| Round 2 | R2.6: evaluate ADR 043 addendum | Rejected | ADR 043 is about provider/AI responsibility refactor, not RDB base repository protocols. |
| Round 2 | R2.7: governor artefacts required after Tier A edits | Fixed | Added this entry and README index row; PR body must keep the Governor section filled. |
| Claude wrapper | C1: update Claude rule post-step surfaces | Fixed | Updated architecture conventions, project status, and reviewed rule timestamps without duplicating AGENTS.md details. |
| Round 3 | R3.1: require a new ADR for validation hooks | Rejected | Additive no-op hooks and AGENTS.md canonical guidance are sufficient for the first domain adoption. |
| Round 3 | R3.2: update `add-api` and wrappers | Rejected | Endpoint authoring should not duplicate Service lifecycle guidance. |
| Round 3 | R3.3: document generic validation-hook test patterns now | Deferred-with-rationale | Defer until a second domain adopts hook overrides and the reusable test pattern is clearer. |
