## ADR Compliance Check

| ADR | Rule | Compliance |
|-----|------|-----------|
| ADR-009 | SQL delta ไม่ใช่ TypeORM migration | ✅ T001, T001b, T026, T027 ทำ SQL delta |
| ADR-016 | RBAC + token policy | ✅ CASL guard T021, token 7d T004b |
| ADR-019 | ใช้ publicId UUID ไม่ใช่ parseInt | ✅ entities ทุกตัวใช้ publicId UUIDv7 |
| ADR-023A | n8n → DMS API → BullMQ, ไม่ตรง Ollama | ✅ FR-011 enforced via T014 gateway |
| ADR-008 | BullMQ ai-batch queue, concurrency=1 | ✅ T013 enqueue ai-batch |
| ADR-007 | Error handling layered (Validation/Business/System) | ✅ T012 ADR-007 error handling |

## Test Evidence

| Suite | Framework | Files | Cases | Result |
|-------|-----------|-------|-------|--------|
| Backend (targeted) | Jest | 3 | 14 | ✅ PASS |
| Frontend | Vitest | 19 | 159 | ✅ PASS |
| **Total** | | **22** | **173** | ✅ **PASS** |

**Source**: `test-report.md` (2026-05-22)

## Gaps & Limitations

| Item | Severity | Note |
|------|----------|------|
| Backend unit test coverage for FR-007a (SELECT FOR UPDATE) | 🟡 Low | `migration-review.service.spec.ts` ทดสอบ DI เท่านั้น — ยังไม่มี test case สำหรับ pessimistic lock race condition |
| E2E test for full migration flow | 🟡 Low | ระบุใน Next Actions ของ test-report.md — ต้องทำบน Staging |
| SC-003 AI accuracy ≥ 90% | 🟢 Info | ตรวจสอบได้เฉพาะหลัง Migration Phase เริ่ม (spot-check 50 docs) |

---

## Recommendations

1. **เพิ่ม unit test สำหรับ FR-007a** — สร้าง mock สำหรับ TypeORM `lock: pessimistic_write` ใน `migration-review.service.spec.ts` เพื่อครอบคลุม concurrent commit scenario
2. **E2E Manual Validation บน Staging** — ตาม Next Actions ใน `test-report.md`
3. **SC-003 accuracy check** — ทำ spot-check หลัง batch แรก 50 docs
