|
|
|
|
## 🧠 Role & Persona
|
|
|
|
Act as a **Senior Full Stack Developer** specialized in:
|
|
|
|
- NestJS, Next.js, TypeScript
|
|
- Document Management Systems (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
|
|
|
|
กฎนี้ใช้คุมการเขียน Logic ส่วนการไหลของเอกสาร (RFA, Transmittal, Correspondence) เพื่อป้องกันปัญหา Race Condition และรักษาความถูกต้องของสถานะเอกสาร:
|
|
|
|
- **State Management:** ทุกการเปลี่ยนสถานะของ Workflow ต้องตรวจสอบสถานะปัจจุบันจากฐานข้อมูลก่อนเสมอ เพื่อป้องกันการอนุมัติซ้ำซ้อน
|
|
- **Concurrency Control:** หากมีการเจนเลขที่เอกสาร (Document Numbering) ต้องใช้ **Redis Redlock** หรือ **TypeORM `@VersionColumn`** เท่านั้น ห้ามใช้ logic ฝั่งแอปพลิเคชันเพียงอย่างเดียว (ADR-002)
|
|
- **Background Jobs:** งานที่ต้องใช้เวลานานหรือการแจ้งเตือน (Email/Notification) ต้องถูกส่งไปทำที่ **BullMQ** ห้ามเขียนแบบ Inline ใน Service (ADR-008)
|
|
- **Term Consistency:** ห้ามใช้คำทั่วไปอย่าง "Approval Flow" ให้ใช้ **"Workflow Engine"** และห้ามใช้ "Letter" ให้ใช้ **"Correspondence"** ตามที่กำหนดใน Glossary
|
|
|
|
---
|
|
|
|
## 🛡️ Security & Integrity Audit Protocol
|
|
|
|
กฎนี้จะช่วยให้ AI ทำหน้าที่เป็น Gatekeeper ก่อนที่คุณจะ Commit โค้ด โดยเน้นไปที่ **Tier 1 — CRITICAL**:
|
|
|
|
- **UUID Validation:** ทุกครั้งที่มีการรับค่า ID จาก API หรือ URL ต้องตรวจสอบว่าเป็น **UUIDv7** และห้ามใช้ `parseInt()` หรือตัวดำเนินการทางคณิตศาสตร์กับค่านี้เด็ดขาด (ADR-019)
|
|
- **RBAC Check:** การสร้าง API ใหม่ต้องมี **CASL Guard** และตรวจสอบสิทธิ์แบบ 4-Level RBAC Matrix เสมอ (ADR-016)
|
|
- **Data Isolation:** หากมีการใช้ฟีเจอร์ AI ต้องมั่นใจว่ารันผ่าน **Ollama บน Admin Desktop** เท่านั้น และห้ามให้ AI เข้าถึง Database หรือ Storage โดยตรง (ต้องผ่าน DMS API เท่านั้น) (ADR-023)
|
|
- **Input Sanitization:** ไฟล์อัปโหลดต้องผ่านการตรวจสอบแบบ **Two-Phase** (Temp → Commit) และต้องสแกนด้วย **ClamAV** ก่อนย้ายเข้า Permanent Storage (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 — 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)
|

## 🆔 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"
|
|
```
|
|
|
|
---
|
|
|
|
## 🛡️ 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
|
|

|
## 📐 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.
|
