- 🔐 **RBAC 4-Level** - ควบคุมสิทธิ์แบบละเอียด (Global, Organization, Project, Contract)
- 📁 **Two-Phase File Storage** - จัดการไฟล์แบบ Transactional พร้อม Virus Scanning
- 🔢 **Document Numbering** - สร้างเลขที่เอกสารอัตโนมัติ ป้องกัน Race Condition
- 🤖 **AI-Assisted Migration** - Ollama + n8n นำเข้าเอกสารเก่า ~20,000 ไฟล์ (ADR-023/028)
- 💬 **AI Document Assistant** - Intent Classification + Tool Layer + Document Chat UI (ADR-024/025/026)
- ⚙️ **AI Admin Console** - Dynamic model/prompt/intent control (ADR-027)
- 📝 **Dynamic Prompt Management** - Prompt templates in DB `ai_prompts`, Redis cache TTL 60s (ADR-029)

- ✅ `specs/03-Data-and-Storage/deltas/` directory bootstrapped (ADR-009 incremental SQL)
- ✅ Regenerated `nestjs-best-practices/AGENTS.md` (188KB, 45 rules × 11 categories incl. LCBP3 project-specific)
- ✅ Helper scripts fixed (bash + pwsh): BASE_DIR, CRLF, color enum, version extraction

- ✅ **Phase 4 (L1–L5 + S1–S4):** Removed `stdin_open`/`tty` from production services; trimmed legacy comments; shared `x-base.yml` anchors; per-stack `.env.example`; secret-manager roadmap (Swarm / Infisical / SOPS)

**New files:** `specs/04-Infrastructure-OPS/04-00-docker-compose/README.md`, `SECURITY-MIGRATION-v1.8.6.md`, `x-base.yml`, 9 per-stack `.env.example` files.

- ✅ Migration n8n Workflow + AI Isolation Plan

### ✅ NestJS 11 + Next.js 16 Migration (Mar 2026)

- ✅ Backend upgraded to **NestJS 11** (Express v5, `@nestjs/*` v11)
- ✅ Shared `RequestWithUser` typed interface (replaced `req: any` across 6 controllers)
- ✅ Frontend upgraded to **Next.js 16** (React 19)
- ✅ Renamed `middleware.ts` → `proxy.ts` (Next.js 16 convention)
- ✅ ADR-019 UUID fixes: Drawing admin pages (5), Contracts, Disciplines, Tags, RFA Types
- ✅ Fixed contract edit form (UUID mismatch), disciplines dropdown (hardcoded projectId), tags crash (empty Select value)

### 🔄 ADR-019 Hybrid UUID Migration (Mar 2026)

- ✅ **Phase 1-4**: Schema, entities, API layer — all 14 tables migrated
- ✅ **Phase 5 (Partial)**: Frontend routes, services, hooks migrated to UUID
- ✅ Drawing search: `projectUuid` sent to backend, resolved in controller
- ✅ Drawing detail page: mock API replaced with real UUID-based services
- 🔄 **Phase 5.4 (Pending)**: FK reference UUID migration — `correspondences/form.tsx`, `user-dialog.tsx`, `numbering/template-tester.tsx`, `rfas/page.tsx` still use `parseInt()` on UUID values (see `specs/05-Engineering-Guidelines/05-07-hybrid-uuid-implementation-plan.md`)
- 📋 **Phase 6**: Unit + integration tests for UUID-based routes

### 🔄 Next: v2.0 — Implementation Phase (AI Runtime + Go-Live)

- 🔄 **AI Runtime Implementation**: Implement ADR-024 (Intent Classifier), ADR-025 (Tool Layer), ADR-026 (Chat UI)
- 🔄 **AI Admin Console**: Implement ADR-027 (Admin Panel)
- 🔄 **Migration Execution**: ADR-028 Staging Queue — Tier 1 (2,000 docs Critical)
- 🔄 **UAT**: ทำ User Acceptance Testing ตาม `01-05-acceptance-criteria.md`
- 🔄 **Security Audit**: ตาม `04-06-security-operations.md`
- 📋 **Go-Live**: Blue-Green Deploy บน QNAP Container Station

### 📅 Post Go-Live

- 📊 Advanced Reporting & Grafana KPI Dashboards (ตาม `00-05-kpi-baseline.md`)
- 🔔 Real-time Notifications (WebSocket)
- 🔍 Queue-based Elasticsearch Indexing (BullMQ)
- 🚀 Performance Optimization & Caching Strategy
