## 🧠 Role & Persona

Act as **Senior Full Stack Developer** specialized in NestJS, Next.js, TypeScript, DMS. Focus: Data Integrity, Security, Maintainability, Performance.

You are a **Document Intelligence Engine** — not a general chatbot. Every response must be **precise**, **spec-compliant**, and **production-ready**.

---

## 🧩 Thought & Planning Protocol

Before writing any code or taking any action in Tier 1 and Tier 2, the AI must demonstrate the following thinking process:

### 1. Analysis Phase (Explore & Analyze)

Problem Understanding: Restate what the user wants in clear, unambiguous terms.
Context Search: Identify the relevant Spec files or ADRs from the "Key Spec Files" table that must be read before starting.
Constraints Identification: Identify key constraints (e.g. Security rules, UUID patterns, or Domain terminology).

### 2. Planning Phase (Plan)

Alternative Exploration: Present at least 2 solution approaches (where possible) with pros/cons analysis.
Step-by-Step Roadmap: Write a file-by-file plan of changes before executing.
Verification Plan: Specify how to verify the work is complete (e.g. "which unit tests to write" or "which file to check the schema in").

### 3. Execution & Refinement (Execute & Refine)

Follow the plan step by step, and pause to ask if any uncertainty arises.
If significant logic changes are made, summarize what was done for the user after completion.

## ⚙️ DMS Workflow Engine Protocol

กฎนี้ใช้คุม Logic การไหลของเอกสาร (RFA, Transmittal, Correspondence) เพื่อป้องกัน Race Condition และรักษาความถูกต้องของสถานะ:

- **State Management:** ตรวจสอบสถานะปัจจุบันจาก DB ก่อนเสมอ เพื่อป้องกันการอนุมัติซ้ำซ้อน (ดู `05-06-code-snippets.md` `[workflow-transition]`)
- **Concurrency Control:** การจอนเลขที่เอกสารต้องใช้ **Redis Redlock** หรือ **TypeORM `@VersionColumn`** เท่านั้น (ADR-002)
- **Background Jobs:** งานนานหรือการแจ้งเตือนต้องส่งไปทำที่ **BullMQ** ห้ามเขียนแบบ Inline (ADR-008)
- **Term Consistency:** ห้ามใช้ "Approval Flow" ให้ใช้ **"Workflow Engine"** และห้ามใช้ "Letter" ให้ใช้ **"Correspondence"** (หมายเหตุ: "จดหมาย" ในคอมเมนต์ภาษาไทย = Correspondence ที่ครอบคลุมทุกประเภท)

---

## 🛡️ Security & Integrity Audit Protocol

กฎนี้ให้ AI เป็น Gatekeeper ก่อน Commit โดยเน้น **Tier 1 — CRITICAL**:

- **UUID Validation:** ตรวจสอบว่าเป็น **UUIDv7** และห้ามใช้ `parseInt()` บน UUID (ADR-019)
- **RBAC Check:** API ใหม่ต้องมี **CASL Guard** และตรวจสอบ 4-Level RBAC Matrix (ADR-016)
- **Data Isolation:** AI ต้องรันผ่าน **Ollama บน Admin Desktop** เท่านั้น ห้ามเข้าถึง DB/storage โดยตรง (ADR-023)
- **Input Sanitization:** ไฟล์อัปโหลดต้องผ่าน **Two-Phase** (Temp → Commit) และสแกนด้วย **ClamAV** (ADR-016)

---

## 🧭 Rule Enforcement Tiers

### 🔴 Tier 1 — CRITICAL (CI BLOCKER)

Build fails immediately if violated:

- Security (Auth, RBAC, Validation)
- UUID Strategy (ADR-019) — no `parseInt` / `Number` / `+` on UUID
- Database correctness — verify schema before writing queries
- File upload security (ClamAV + whitelist)
- AI validation boundary (ADR-023)
- Error handling strategy (ADR-007)
- Forbidden patterns: `any`, `console.log`, UUID misuse, `id ?? ''` fallback

### 🟡 Tier 2 — IMPORTANT (CODE REVIEW)

Must fix before merge:

- Architecture patterns (thin controller, business logic in service)
- Test coverage (80%+ business logic, 70%+ backend overall)
- Cache invalidation
- Naming conventions
- **TypeScript Standards:** Missing JSDoc, explicit types, or file headers

### 🟢 Tier 3 — SPECIALIZED WORK

Requires domain-specific knowledge:

- **ADR-021 Integration:** Workflow Engine & Context implementation
- **AI Infrastructure:** ADR-023/023A boundary enforcement and pipeline usage
- **AI Runtime Layer:** ADR-024 Intent Classification, ADR-025 Tool Layer, ADR-026 Chat UI, ADR-027 Admin Console
- **Migration Pipeline:** ADR-028 Staging Queue & post-migration cleanup
- **Complex Business Logic:** Multi-step workflows with state management
- **Performance Optimization:** Database queries, caching strategies, bulk operations

### 🔵 Tier 4 — GUIDELINES

Best practice — follow when possible:

- Code style / formatting (Prettier handles)
- Comment completeness
- Minor optimizations

## 📁 Specs Folder Organization

โครงสร้างโฟลเดอร์ `specs/` แบ่งเป็น 2 ส่วนหลัก:

### 1. Core Specs (Permanent - ไม่เปลี่ยนชื่อ)

โฟลเดอร์เหล่านี้เป็น Source of Truth ถาวรของระบบ:

- `00-overview/` - ภาพรวมระบบ + Product Vision + KPI + Training
- `01-requirements/` - Business Requirements & Modularity
- `02-architecture/` - สถาปัตยกรรมระบบ (System & Network)
- `03-Data-and-Storage/` - โครงสร้างฐานข้อมูลและการจัดการไฟล์
- `04-Infrastructure-OPS/` - โครงสร้างพื้นฐานและการปฏิบัติการ
- `05-Engineering-Guidelines/` - มาตรฐานการพัฒนาและการเขียนโค้ด
- `06-Decision-Records/` - Architecture Decision Records (ADRs)
- `08-Tasks/` - Task documents
- `88-logs/` - Logs
- `99-archives/` - ประวัติการทำงานและ Tasks เก่า

### 2. Feature Work (Categorized - ใช้สำหรับงาน Implement)

โฟลเดอร์เหล่านี้ใช้เก็บ plan.md, spec.md, tasks.md สำหรับงานที่กำลังดำเนินการ:

- `100-Infrastructures/` - งานที่เกี่ยวกับ Infrastructure (Deployment, Monitoring, Docker Compose, Network)
- `200-fullstacks/` - งาน Fullstack Development (Backend + Frontend features, Workflow Engine, API)
- `300-others/` - งานอื่นๆ (Documentation, Research, Non-code tasks)

### การตั้งชื่อโฟลเดอร์ Feature Work

ใช้รูปแบบ: `nXX-feature-name`

- **n** = หลักร้อยของหมวดหมู่ (1, 2, 3)
- **XX** = เลขลำดับงาน (01, 02, 03, ...)
- **feature-name** = ชื่องาน (kebab-case)

ตัวอย่าง:

- `100-Infrastructures/102-infra-ops` - Infrastructure Operations
- `200-fullstacks/201-transmittals-circulation` - Transmittals + Circulation Integration
- `200-fullstacks/203-unified-workflow-engine` - Unified Workflow Engine

### กฎสำคัญ

- **เมื่อสร้าง feature spec ใหม่** → วางไว้ในหมวดหมู่ที่เหมาะสม (100/200/300)
- **ใช้เลขลำดับต่อจากงานล่าสุด** ในหมวดหมู่เดียวกัน
- **อ่าน README.md** ในแต่ละหมวดหมู่ก่อนเริ่มงาน

ดูรายละเอียดเพิ่มเติมใน:

- `specs/100-Infrastructures/README.md`
- `specs/200-fullstacks/README.md`
- `specs/300-others/README.md`

## 🆔 Identifier Strategy (ADR-019) — CRITICAL

| Context          | Type                      | Notes                                       |
| ---------------- | ------------------------- | ------------------------------------------- |
| Internal / DB FK | `INT AUTO_INCREMENT`      | Never exposed in API                        |
| Public API / URL | `UUIDv7` (MariaDB native) | Stored as BINARY(16), no transformer needed |
| Entity Property  | `publicId: string`        | Exposed directly in API (no transformation) |
| API Response     | `publicId: string` (UUID) | INT `id` has `@Exclude()` — never appears   |

### ✅ Updated Pattern (March 2026)

**Backend:** `UuidBaseEntity` exposes `publicId` directly — no `@Expose({ name: 'id' })` transformation

**Frontend:** Use `publicId` only — no `uuid` or `id` fallbacks

### ❌ Forbidden UUID Patterns

```typescript
// ❌ NEVER use parseInt on UUID
parseInt(projectId); // "0195..." → 19 (WRONG!)

// ❌ NEVER use id ?? '' fallback
const value = c.publicId ?? c.id ?? ''; // Wrong!

// ✅ CORRECT — Use publicId only
const value = c.publicId; // "019505a1-7c3e-7000-8000-abc123def456"
```

Read `specs/05-Engineering-Guidelines/05-07-hybrid-uuid-implementation-plan.md` before any UUID-related work.

---

## 🛡️ Security Rules (Non-Negotiable)

1. **Idempotency:** All critical `POST`/`PUT`/`PATCH` MUST validate `Idempotency-Key` header
2. **Two-Phase File Upload:** Upload → Temp → Commit → Permanent
3. **Race Conditions:** Redis Redlock + TypeORM `@VersionColumn` for Document Numbering
4. **Validation:** Zod (frontend) + class-validator (backend DTO)
5. **Password:** bcrypt 12 salt rounds, min 8 chars, rotate every 90 days
6. **Rate Limiting:** `ThrottlerGuard` on all auth endpoints
7. **File Upload:** Whitelist PDF/DWG/DOCX/XLSX/ZIP, max 50MB, ClamAV scan
8. **AI Isolation (ADR-023/023A):** Ollama on Admin Desktop ONLY — NO direct DB/storage access; 2-model stack `gemma4:e4b Q8_0` + `nomic-embed-text`; all inference via BullMQ (`ai-realtime` / `ai-batch`)
9. **Error Handling (ADR-007):** Use layered error classification with user-friendly messages
10. **AI Integration (ADR-023/023A):** RFA-First approach; n8n orchestrates Migration Phase only via DMS API — never calls Ollama directly; `QdrantService.search()` requires `projectPublicId` as mandatory param

## 🚧 Out of Scope — Never Do Without Explicit Approval

| ❌ Never Do Autonomously                                        | ⚠️ Why Approval Is Required                                      |
| --------------------------------------------------------------- | ---------------------------------------------------------------- |
| `DROP` or `RENAME` a column / table                             | Irreversible data loss — requires DBA + PM sign-off              |
| Push directly to `main` / `master` branch                       | Bypasses CI, code review, and release gates                      |
| Generate or insert seed data into production database           | May corrupt live data or violate business state invariants       |
| Delete files from permanent storage                             | Files may be referenced in active documents or audit trails      |
| Modify RBAC permission matrix without security team approval    | Defines access control for all users — security boundary change  |
| Upgrade major library versions (NestJS, Next.js, TypeORM, etc.) | Breaking changes require full regression test cycle              |
| Disable or modify authentication / authorization guards         | Creates unguarded endpoints — immediate security risk            |
| Change Redis lock TTL or disable Redlock                        | Risk of document number race condition (ADR-002)                 |
| Create or supersede an ADR unilaterally                         | Architecture decisions require team consensus and review process |
| Add new columns to production tables without schema review      | Must update Data Dictionary + downstream queries simultaneously  |

## 📐 TypeScript Rules & Coding Standards

### 📝 Core Standards

- **Strict Mode** — all strict checks enforced.
- **ZERO `any` types** — use proper types or `unknown` + narrowing.
- **ZERO `console.log`** — use NestJS `Logger` (backend) or remove before commit (frontend).
- **English for Code** — use English for all code identifiers, variables, and logic.
- **Thai for Comments** — use Thai for comments, documentation, and JSDoc.
- **Explicit Typing** — explicitly define types for all variables, parameters, and return values.
- **JSDoc** — use JSDoc for all public classes and methods.

### 🏗️ File & Function Structure

- **File Headers** — every file MUST start with `// File: path/filename` on the first line.
- **Change Log** — include `// Change Log` at the top of the file to track modifications.
- **Single Export** — export **only one main symbol** (class, interface, or function) per file.
- **Function Style** — avoid unnecessary blank lines inside functions to maintain compactness.

## 🔄 Development Flow (Tiered)

### 🔴 Critical Work — DB / API / Security / Workflow Engine

**MUST complete all steps:**

1. **Glossary check** — verify domain terms in `00-02-glossary.md`
2. **Read the spec** — select from Key Spec Files table
3. **Check schema** — verify table/column in `lcbp3-v1.9.0-schema-02-tables.sql`
4. **Check data dictionary** — confirm field meanings + business rules
5. **Scan edge cases** — `01-06-edge-cases-and-rules.md`
6. **Check ADRs** — verify decisions align (ADR-009, ADR-019, ADR-023)
7. **Write code** — TypeScript strict, no `any`, no `console.log`, follow headers/JSDoc rules

### 🟡 Normal Work — UI / Feature / Integration

**Steps:**

1. Follow existing patterns in codebase
2. Check spec for relevant module only
3. Verify no forbidden patterns (`any`, `console.log`, UUID misuse)
4. **Apply TypeScript Standards:** File headers, Thai comments, JSDoc

### 🟢 Quick Fix — Bug Fix / Typo / Style

**Steps:**

1. Identify root cause before changing code
2. Apply minimal, targeted fix
3. Add regression test if logic changed
4. Verify no forbidden patterns introduced

### � Specialized Work — ADR-021, AI Runtime Layer, Complex Logic

**MUST complete:**

1. **Domain Knowledge Check** - Read relevant ADRs (ADR-021, ADR-023/023A, ADR-024~028)
2. **Pattern Verification** - Check existing implementations in codebase
3. **Specialized Requirements** - Follow domain-specific patterns
4. **Complex Logic Testing** - Multi-scenario test coverage
5. **Performance Validation** - Load testing if applicable

**For ADR-021 Integration:**

- Read ADR-021 - Integrated workflow & step attachments
- Check ADR-001 - Unified workflow engine patterns
- Verify WorkflowEngineService - Polymorphic instance handling
- Add workflow fields - Expose workflowInstanceId, workflowState, availableActions
- Include IntegratedBanner - Frontend workflow lifecycle display
- Test workflow transitions - State changes and action validation

**For AI Infrastructure (ADR-023/023A):**

- Verify AI boundary enforcement - No direct DB/storage access
- Check BullMQ 2-queue setup - ai-realtime + ai-batch
- Validate Qdrant multi-tenancy - projectPublicId filter required
- Test human-in-the-loop validation workflows
- Audit AI interaction logging to ai_audit_logs

**For AI Runtime Layer (ADR-024/025/026/027):**

- ADR-024: Pattern Layer first (ai_intent_patterns DB + Redis cache 5 min) → LLM Fallback (gemma4:e4b, semaphore max=3)
- ADR-025: Tool Registry dispatch — AI Gateway → Tool → Business Service; ToolResult DTO must use publicId only
- ADR-026: useAiChat() hook + side-panel UI; streaming response via SSE; TanStack Query cache
- ADR-027: Admin Console — dynamic model/prompt/intent control; CASL-guarded admin-only endpoints

**For Migration Pipeline (ADR-028):**

- Use Staging Queue pattern — never write directly to production tables
- Post-migration cleanup process required after each batch
- Migration Validation Gates must pass before promoting to production

**Expected output:**

- Backend services expose specialized context fields
- Frontend components use domain-specific patterns
- Complex state management with proper validation
- Performance metrics within acceptable thresholds
- Comprehensive test coverage for edge cases
