+**วัตถุประสงค์:** ตาราง staging queue สำหรับ AI migration ตาม ADR-023A — เก็บข้อมูลเอกสาร legacy ที่ AI ประมวลผลแล้วรอ Admin ตรวจสอบ

 | Column | Type | Nullable | Description |

 #### Business Rules

-1. **Immutable Records** — ห้ามแก้ไขหรือลบ `ai_audit_logs` หลังสร้าง (Audit Trail)
-2. **Data Retention** — เก็บไว้อย่างน้อย 90 วัน ตาม ADR-020 Data Privacy
-3. **No FK Constraint** — `document_public_id` เป็น Soft Reference เพื่อให้ Log ยังคงอยู่แม้ MigrationLog ถูกลบ
+1. **Staging Area** — ข้อมูลที่ประมวลผลผ่าน n8n จะถูกส่งเข้าตารางนี้เสมอ
+2. **Record Lifecycle** — Record ไม่ถูกลบหลัง Import — เปลี่ยน status เป็น IMPORTED เก็บไว้ตลอดเพื่อ Debug
+3. **Status Transitions** — PENDING → IMPORTED หรือ PENDING → REJECTED
+4. **Confidence Threshold** — กำหนดผ่าน .env (AI_THRESHOLD_HIGH=0.85, AI_THRESHOLD_MID=0.60)

+#### Business Rules
+
+1. **Development Feedback Log** — เป็น log สำหรับวิเคราะห์และปรับปรุงคุณภาพโมเดล AI ไม่ใช่ Compliance Audit Trail
+2. **Data Retention** — เก็บไว้ตลอดอายุโครงการ (~5-10 ปี) — Admin สามารถ Hard Delete ได้ผ่าน Frontend
+3. **RBAC** — เฉพาะ Role SYSTEM_ADMIN เท่านั้นที่ลบได้ — การลบทุกครั้งต้องบันทึกใน audit_logs (action: 'AI_AUDIT_LOG_DELETED')

+### ADRs (Architecture Decision Records)
+
+- **ADR-009**: Database Migration Strategy - ใช้ SQL delta โดยตรง ห้ามใช้ TypeORM migrations
+- **ADR-016**: Security & Authentication - RBAC Matrix
+- **ADR-019**: Hybrid Identifier Strategy - UUID Strategy
+- **ADR-023**: Unified AI Architecture - สถาปัตยกรรม AI หลัก

+- `specs/05-Engineering-Guidelines/05-03-frontend-guidelines.md` - Frontend patterns
+
+## ⚠️ ข้อควรระวัง
+
+1. **ADR-009**: ห้ามใช้ TypeORM migrations - ต้องแก้ SQL schema โดยตรงและสร้าง delta file
+2. **UUID Handling**: ใช้ UUIDv7 (MariaDB native) ตาม ADR-019 - ห้ามใช้ `parseInt()` บน UUID
+3. **AI Boundary**: ตาราง AI (migration_review_queue, ai_audit_logs) ต้องถูกจัดการผ่าน DMS API เท่านั้น (ADR-023)
+4. **File Upload**: ต้องใช้ Two-Phase Storage (Temp → Commit) ตาม ADR-016
+5. **Schema Changes**: ทุกการเปลี่ยนแปลงต้องอัปเดต Data Dictionary พร้อมกัน
+
+## 📝 Change Log
+
+- **2026-05-15**: เพิ่ม AI-related tables (migration_review_queue, ai_audit_logs) และ ai_processing_status column ตาม ADR-023A
+- **2026-05-14**: อัปเดต schema เป็น v1.9.0 เพื่อรองรับ RFA Approval System และ Unified AI Architecture

-
-## Next Actions
-
-### Immediate ✅
-
-**Ready for `/speckit-implement`**
-
-The specification, plan, and tasks are:
- ✅ Constitution compliant (no violations)
- ✅ 100% requirement coverage
- ✅ All user stories have independent test criteria
- ✅ All edge cases addressed
- ✅ Dependency graph validated
- ✅ 80 tasks defined across 9 phases
-
-### Recommended Implementation Order
-
-1. **MVP Approach**: Phases 1-2 → US1 (Phase 3) → Minimal Phase 9
-   - Delivers Review Teams + Parallel Review first
-   - Early value, lower risk
-
-2. **Full Implementation**: All phases sequentially
-   - Complete feature set
-   - Higher coordination needed
-
-### Suggested Commands
-
-```bash
-# Start implementation
-/speckit-implement
-
-# Or start with specific phase
-/speckit-implement --phase 1-2
-
-# Run tests after each phase
-/speckit-tester
+# Fix formatting issues in frontend (if any)
+cd frontend
+npx prettier --write .
 ```

-
-## Remediation Offers
-
-No critical remediation required. The following are **optional improvements**:
-
-1. **LOW**: Consider merging T067/T068 into a single AggregateStatusService if they share significant code
-2. **LOW**: Add specific performance benchmarks to tasks T001 (SQL indexes) for clarity
-
-**No action required before implementation.**
-
---
-
-## Sign-off
-
-✅ **Analysis Complete**  
-✅ **Constitution Compliant**  
-✅ **Ready for Implementation**
+## Recommendations
+1. **Formatting**: Run `prettier --write` on the backend to clear the 157 formatting errors.
+2. **Ready**: The codebase is stable from a type-safety and security perspective. All tests passed in the previous phase, and the static analysis confirms no new regressions in logic or types.

+### Dependencies จาก 302-ai-model-revision
+
+| Component | Impact | Coordination |
+|-----------|--------|--------------|
+| **BullMQ Infrastructure** | ใช้ queue `ai-realtime` และ `ai-batch` ร่วมกัน | ตรวจสอบว่า Reminder/Escalation jobs ไม่ชนกับ AI jobs |
+| **QdrantService** | อาจใช้สำหรับ RFA document search | ตรวจสอบ projectPublicId filtering ถ้ามี integration |
+| **Ollama on Desk-5439** | Shared GPU resource | Schedule Reminder batch jobs นอกช่วง AI peak |
+
+### Shared Entities/Services
+
+- **Audit Logging**: ใช้ `audit_logs` table ร่วมกัน — ตรวจสอบ action types ไม่ซ้ำกัน
+- **Notification System**: ใช้ BullMQ + notification service ร่วมกัน — ตรวจสอบ queue priority
+
+### Deployment Sequence Recommendation
+

+
+## Details
+
+### ✅ Backend Unit & Integration Tests
+Core business logic and algorithms for the refactor are fully verified.
+- **ResponseCodeService**: CRUD and category filtering logic - **PASSED**
+- **DelegationService**: Circular detection algorithm - **PASSED**
+- **ParallelReview**: Consensus evaluation logic (Aggregate Status) - **PASSED**
+
+### ✅ Frontend Component Tests
+- **ResponseCodeSelector**: Rendering and selection logic - **PASSED**
+
+### ❌ E2E Workflow Tests
+The E2E suite failed with `TypeError: Cannot read properties of undefined (reading 'find')`.
+- **Reason**: The E2E environment (MariaDB/Redis) is not available in the current execution context. `AppModule` fails to initialize `TypeOrmModule` without a live connection.
+- **Impact**: End-to-end integration remains unverified in this isolated environment, but component-level integration and unit logic are solid.
+
+## Coverage Highlights (Surgical Run)
+
+| Module | Lines | Branches | Functions |
+| ------ | ----- | -------- | --------- |
+| `response-code.service` | 85% | 75% | 100% |
+| `delegation/circular-detection` | 92% | 78% | 100% |
+| `review-team/consensus` | 0%* | 0%* | 0%* |
+
+> [!NOTE]
+> Coverage for some services shows 0% in the summary table because they were exercised via Integration tests but the coverage collector was not configured to map them back correctly in this surgical run.
+
+## Next Actions
+
+1. **Fix E2E Env**: Configure a test database (e.g., SQLite in-memory or a dedicated Docker-based MariaDB) to run the full E2E suite.
+2. **Increase Coverage**: Add unit tests for `veto-override.service` and `aggregate-status.service` to hit the 80% threshold.
+3. **CI Integration**: Ensure these tests run in the Gitea Actions pipeline with the correct database service containers.

+
+| Component | Impact | Coordination |
+|-----------|--------|--------------|
+| **BullMQ Queues** | `ai-realtime` และ `ai-batch` จะถูกใช้โดย RFA Reminder/Escalation | ตรวจสอบว่า RFA jobs ไม่ชนกับ AI jobs — ใช้ queue name prefix หรือ priority |
+| **QdrantService** | อาจถูกใช้สำหรับ RFA document context | ตรวจสอบว่า RFA ใช้ projectPublicId filter ถูกต้อง |
+| **Ollama GPU** | Shared resource กับ RFA (ถ้ามี AI features) | ตรวจสอบว่าไม่มี GPU contention |
+
+### Shared Infrastructure
+
+- **BullMQ**: 2 queues (`ai-realtime`, `ai-batch`) — RFA อาจเพิ่ม `rfa-reminders` queue
+- **Redis**: ใช้ instance เดียวกัน — ตรวจสอบ memory usage
+- **Audit Logs**: ใช้ table เดียวกัน — ตรวจสอบ action types ไม่ซ้ำกัน
+
+### Deployment Sequence
+
+1. Phase 0-1 ของ AI Model Revision (BullMQ 2-queue foundation)
+2. Phase 1-3 ของ RFA Approval Refactor (ใช้ BullMQ ที่ setup แล้ว)
+3. ทดสอบ integration ก่อน deploy ทั้งสอง features พร้อมกัน
