-## TROUBLESHOOTING GUIDE
-
-### "Database Connection Timeout"
-```
-Diagnosis:
-1. Check if PostgreSQL container is running: docker-compose ps
-2. Verify DATABASE_URL in .env
-3. Check PgBouncer if production: psql -h localhost -p 6432 -U pgbouncer
-4. Look for connection limit reached: SELECT count(*) FROM pg_stat_activity
-
-Fix:
-├── Restart: docker-compose restart postgres
-├── Increase PgBouncer pool: PGBOUNCER_POOL_SIZE=30
-└── Check slow queries: pg_stat_statements
-```
-
-### "Redis Connection Refused"
-```
-Diagnosis:
-1. Check Redis container: docker-compose ps redis
-2. Verify REDIS_URL in .env
-3. Check port: redis-cli -p 6379 ping
-4. Check memory: redis-cli INFO memory
-
-Fix:
-├── Restart: docker-compose restart redis
-├── Flush if needed: redis-cli FLUSHALL (dev only!)
-└── Monitor: redis-cli --stat
-```
-
-### "Typesense Index Not Found"
-```
-Diagnosis:
-1. Check Typesense container: docker-compose ps typesense
-2. Verify TYPESENSE_API_KEY in .env
-3. List indexes: curl http://localhost:8108/collections -H "X-TYPESENSE-API-KEY: <key>"
-4. Check sync job logs
-
-Fix:
-├── Re-seed: pnpm db:seed
-├── Reindex: DELETE /listings index, then rebuild
-└── Monitor: Typesense dashboard http://localhost:8108/dashboard
-```
-
-### "Tests Failing with 'Port Already in Use'"
-```
-Diagnosis:
-1. Check running processes: lsof -i :3001 (macOS) or netstat -ano (Windows)
-2. Docker containers: docker ps
-
-Fix:
-├── Kill process: kill -9 <PID>
-├── Stop containers: docker-compose down
-├── Update port in .env.test
-└── Ensure cleanup in global-teardown.ts
-```

-- auth, listings, search, admin, analytics, payments, subscriptions, notifications, leads, inquiries, reviews, agents, shared
-
-**❌ Incomplete Layering (3 modules)**:
-- `health`: Infrastructure only (Liveness/readiness checks) — *Simple module, acceptable*
-- `metrics`: Infrastructure + Presentation (Prometheus collection) — *Needs domain logic*
-- `mcp`: Presentation only — *MCP protocol bridge, needs domain expansion*
-
-### API Statistics
-- **Total Files**: 788 TypeScript files
-- **Code (excluding tests)**: 23,926 LOC
-- **Unit Tests**: 229 spec files (.spec.ts)
-- **Avg Lines/File**: 30-120 LOC (real implementation, not skeleton)
-- **Layering Distribution**:
-  - Domain: 182 files (strategy patterns, value objects, entities)
-  - Application: 293 files (CQRS handlers, DTOs, error handling)
-  - Infrastructure: 145 files (Prisma repositories, external integrations)
-  - Presentation: 119 files (NestJS controllers, guards, decorators)
-
-### Key Implementation Patterns
-✅ **CQRS Pattern** — All modules use command/query separation
-✅ **Repository Pattern** — Prisma-based data access layer
-✅ **Error Handling** — Consistent exception filters, business error mapping
-✅ **Validation** — Class validators on all DTOs
-✅ **Testing** — 229 unit tests + integration tests
-✅ **Type Safety** — Strict TypeScript, no implicit `any`

-## Error Handling Convention
+## Kỷ Luật Commit & Push (Bắt Buộc)
 
-### Overview
+> Để tránh conflict khi nhiều agent/engineer làm việc song song, toàn bộ team PHẢI tuân thủ các quy định sau. Nguồn: [GOO-91](/GOO/issues/GOO-91) (chỉ thị từ CEO qua [GOO-88](/GOO/issues/GOO-88)).
 
-All application-layer error handling uses **domain exceptions** from `@modules/shared/domain/domain-exception`. Never import exception classes from `@nestjs/common` in handlers — use the project's own domain exceptions instead.
+1. **Commit ngay khi hoàn thành task** — mỗi task = một commit (hoặc một chuỗi commit nhỏ liên quan). Không gom nhiều task không liên quan vào một commit lớn.
+2. **Pull/rebase trước khi push** — luôn chạy `git pull --rebase origin <branch>` trước `git push` để giảm merge conflict.
+3. **Push ngay sau commit** — không giữ commit local quá 1 ngày làm việc. Commit không push = rủi ro mất việc + conflict tăng.
+4. **Conventional Commits** — bắt buộc (`feat:`, `fix:`, `chore:`, `refactor:`, `docs:`, `test:`, `style:`, `perf:`). Xem [Quy Ước Commit](#quy-ước-commit) bên dưới.
+5. **KHÔNG push trực tiếp lên `main` / `master`** — luôn dùng feature branch + Pull Request. Branch chính được bảo vệ bằng GitHub branch protection rules.
+6. **PR phải pass CI** (`lint` → `typecheck` → `test` → `build`) trước khi merge. PR đỏ CI không được merge dù đã approve.
+7. **Squash-merge khi merge PR** — giữ history trên `main` sạch, mỗi PR = một commit logic.
+8. **Xóa feature branch sau khi merge** — tránh branch sprawl. GitHub có auto-delete branch sau merge; bật nó trong repo settings.
 
-The `GlobalExceptionFilter` catches all exceptions and normalizes them into a consistent JSON response with structured error codes.
+### Flow nhanh cho mỗi task
+
+```bash
+# 1. Tạo/chuyển sang feature branch (KHÔNG commit trực tiếp vào main)
+git checkout -b feature/goo-xx-short-description
+
+# 2. Làm việc, khi hoàn thành task:
+git add <files>
+git commit -m "feat(scope): mô tả ngắn"
+
+# 3. Đồng bộ & push
+git pull --rebase origin main   # hoặc develop
+git push -u origin feature/goo-xx-short-description
+
+# 4. Mở PR, chờ CI xanh + review, squash-merge, xóa branch
+```

+
+## Quy Ước Xử Lý Lỗi
+
+### Tổng Quan
+
+Toàn bộ xử lý lỗi ở tầng ứng dụng sử dụng **domain exceptions** từ `@modules/shared/domain/domain-exception`. Không bao giờ import các lớp exception từ `@nestjs/common` trong handlers — hãy dùng domain exceptions của dự án.
+
+`GlobalExceptionFilter` bắt tất cả các exception và chuẩn hóa chúng thành một JSON response nhất quán với error codes có cấu trúc.
 
 ### Domain Exceptions
 
-| Exception | HTTP Status | When to use |
+| Exception | HTTP Status | Khi nào dùng |
 |---|---|---|
-| `NotFoundException(entity, id?)` | 404 | Entity not found in database |
-| `ValidationException(message, details?)` | 400 | Invalid input, business rule violation, value object creation failure |
-| `ConflictException(message)` | 409 | Duplicate resource, idempotency violation |
-| `UnauthorizedException(message?)` | 401 | Invalid/expired credentials or tokens |
-| `ForbiddenException(message?)` | 403 | Authenticated but not authorized for the action |
+| `NotFoundException(entity, id?)` | 404 | Không tìm thấy entity trong database |
+| `ValidationException(message, details?)` | 400 | Dữ liệu đầu vào không hợp lệ, vi phạm business rule, lỗi tạo value object |
+| `ConflictException(message)` | 409 | Tài nguyên bị trùng lặp, vi phạm idempotency |
+| `UnauthorizedException(message?)` | 401 | Thông tin xác thực hoặc token không hợp lệ/đã hết hạn |
+| `ForbiddenException(message?)` | 403 | Đã xác thực nhưng không được phép thực hiện hành động |

+### Các Mẫu Theo Từng Tầng
 
 #### Command/Query Handlers
 
-Handlers throw domain exceptions directly. No try-catch wrapping needed — the `GlobalExceptionFilter` handles uncaught exceptions.

 #### Controllers
 
-Controllers are thin delegation layers — they dispatch to the command/query bus and return the result. No error handling needed at the controller level.
+Controllers là các tầng ủy quyền mỏng — chúng dispatch tới command/query bus và trả về kết quả. Không cần xử lý lỗi ở tầng controller.
 
 #### Domain Services / Value Objects
 
-Use the `Result<T, E>` pattern from `@modules/shared/domain/result`:
+Sử dụng mẫu `Result<T, E>` từ `@modules/shared/domain/result`:

@@ -85,8 +321,89 @@ try {
 // Handlers should unwrap Result and throw on error
 ```
 
-### Repository Return Types
+### Kiểu Trả Về Của Repository
 
-All repository read methods must return explicitly typed DTOs — never `Promise<any>` or `PaginatedResult<any>`. Define read DTOs in the domain layer alongside the repository interface.
+Tất cả các phương thức đọc của repository phải trả về DTOs được định kiểu rõ ràng — không bao giờ dùng `Promise<any>` hoặc `PaginatedResult<any>`. Định nghĩa read DTOs ở tầng domain cùng với interface của repository.

-# GoodGo Frontend: i18n + A11y Implementation Quick Reference
-
-## 🎯 Key Findings at a Glance
-
-### Current State
-- ✅ **Next.js 14** with App Router (well-structured)
-- ✅ **React 18** + TypeScript (type-safe)
-- ✅ **Tailwind CSS** with dark mode support (HSL-based theme)
-- ✅ **Good component library** (~35 components)
-- ✅ **Some A11y basics** in place (semantic HTML, ARIA labels, skip link)
-- ❌ **NO i18n setup** (everything hardcoded Vietnamese)
-- ❌ **A11y gaps** (focus management, some ARIA missing, color contrast TBD)
-
-### Strategic Entry Points for Implementation
-
-#### 1. **i18n Entry Points** (Priority 1)
-```
-Files to modify for i18n:
-├── app/layout.tsx                    → Add i18n provider
-├── middleware.ts                     → Add locale routing
-├── app/(public)/layout.tsx           → Navigation text
-├── app/(auth)/login/page.tsx         → Form labels + errors
-├── app/(auth)/register/page.tsx      → Form labels + errors
-├── components/listings/listing-form-steps.tsx → Multi-step form labels
-├── components/search/filter-bar.tsx  → Filter options + city names
-├── lib/validations/*.ts             → Zod error messages
-└── [All other components with text]
-
-Total files to update: ~25-30 files with hardcoded strings
-```
-
-#### 2. **A11y Critical Fixes** (Priority 1.5)
-```
-Components needing A11y updates:
-├── components/ui/dialog.tsx         → Focus trapping + focus restoration
-├── components/listings/image-gallery.tsx → Keyboard nav + ARIA
-├── components/search/filter-bar.tsx  → Proper labeling + ARIA
-├── app/(dashboard)/layout.tsx        → Tab focus management
-└── Across all forms                 → Error message association
-
-Tasks:
-- Add focus trapping in modals
-- Verify color contrast (WCAG AA)
-- Add aria-busy to loading states
-- Add proper aria-label to icon buttons
-- Link form errors to inputs with aria-describedby
-```
-
-#### 3. **Message File Structure for i18n**
-```
-public/locales/
-├── en.json
-│   ├── common: { home, search, dashboard, logout, ... }
-│   ├── auth: { login, register, email, password, ... }
-│   ├── property: { apartment, house, villa, ... }
-│   ├── transaction: { sale, rent, ... }
-│   ├── directions: { north, south, east, ... }
-│   ├── status: { draft, active, sold, ... }
-│   ├── validation: { required, min_length, ... }
-│   └── errors: { oauth_failed, access_denied, ... }
-└── vi.json
-    └── [Same structure]

-  it('renders Vietnamese labels', () => { ... });
-  it('renders English labels', () => { ... });
-});
-```
-
-### E2E Tests
-```typescript
-// Test locale switching
-- /en/login → English
-- /vi/login → Vietnamese
-- /en/dashboard → English dashboard
-```

-
-## 📊 Estimated Timeline
-
-| Phase | Duration | Effort |
-|-------|----------|--------|
-| Setup | 2-3h | Low |
-| Core Refactoring | 6-8h | Medium |
-| Components | 4-6h | Medium |
-| A11y Fixes | 4-6h | Low-Medium |
-| Testing | 3-4h | Medium |
-| **Total** | **19-27h** | **~3-4 days** |
-
----
-
-## 🚀 Implementation Order (Recommended)
-
-1. **Setup i18n infrastructure** (creates foundation)
-2. **Update middleware + root layout** (enables routing)
-3. **Extract & centralize all text** (main work)
-4. **Fix A11y issues** (parallelize with #3)
-5. **Test thoroughly** (final verification)
-
----
-
-## 💡 Quick Win Opportunities
-
-These can be done immediately:
-1. Create message file structure (30 min)
-2. Add focus trap to dialog (30 min)
-3. Add aria-busy to spinners (20 min)
-4. Color contrast audit (1 hour)
-5. Icon button aria-labels (30 min)
-
----
-
-## 📝 Notes for Implementation
-
-### Locale Detection (middleware)
-```typescript
-// Check in order: URL > cookie > header > default
-function getLocale(request) {
-  // 1. URL pathname: /en/* or /vi/*
-  // 2. Cookie: goodgo_locale
-  // 3. Header: Accept-Language
-  // 4. Default: vi
-}
-```
-
-### Message Fallback Strategy
-```typescript
-// If translation missing, use English as fallback
-// Otherwise fallback to Vietnamese (primary)
-```
-
-### Performance Considerations
-- Keep message files < 100KB each
-- Lazy load per-page messages if needed
-- Static generation for SEO-critical pages

-
-## 📊 Test Scenarios Implemented
-
-| Scenario | File | Focus | VUs | Duration | Key Endpoints |
-|----------|------|-------|-----|----------|--------------|
-| Search Load | `load-tests/search.k6.js` | Public search performance | 50 | 4m | `GET /search`, `GET /search/geo` |
-| Authentication | `load-tests/auth.k6.js` | Auth throughput & rate limits | 10 | 2m | `POST /auth/register`, `POST /auth/login` |
-| Listing Creation | `load-tests/listings.k6.js` | Authenticated listing CRUD | 5 | 2m | `POST /listings`, `GET /listings/:id` |
-| Payments | `load-tests/payments.k6.js` | Payment initiation & status | 10 | 2m | `POST /payments`, `GET /payments/:id` |
-| Combined | `load-tests/all-scenarios.k6.js` | Realistic mixed load | 50 | 5m | Multiple endpoints |
-
----
-
-## 🔐 Authentication Methods
-
-### Option 1: Cookie-Based (Recommended for Browser-Like Tests)
-```javascript
-const loginRes = http.post(`${BASE_URL}/auth/login`, { phone, password });
-// Cookies automatically managed by K6
-const profileRes = http.get(`${BASE_URL}/auth/profile`);
-```
-
-### Option 2: Bearer Token (Recommended for API-Only Tests)
-```javascript
-const loginRes = http.post(`${BASE_URL}/auth/login`, { phone, password });
-const { accessToken } = loginRes.json();
-const headers = { Authorization: `Bearer ${accessToken}` };
-const profileRes = http.get(`${BASE_URL}/auth/profile`, { headers });
-```
-
-See K6_ENDPOINTS_SUMMARY.md for full examples.

-
-## ⚡ Rate Limits
-
-Respect these limits in your load tests:
-
-| Endpoint | Limit | Window | Action on Exceeded |
-|----------|-------|--------|-------------------|
-| `/auth/register` | 5 | per hour | Returns 429 |
-| `/auth/login` | 5 | per hour | Returns 429 |
-| `/auth/refresh` | 5 | per hour | Returns 429 |
-| `/payments/callback/*` | 20 | per minute | Returns 429 |
-| All others | None | N/A | Quota gates apply for writes |
-
-**K6 Handling:**
-```javascript
-check(res, {
-  'status not rate limited': (r) => r.status !== 429,
-  'status success or expected': (r) => [200, 201, 400, 404].includes(r.status),
-});
-```

-## 🧪 Integration with Existing Tests
-
-### Complement, Don't Replace
-
-K6 is for **load testing** (performance under concurrent load).
-Existing tests serve different purposes:
-
-| Test Type | Tool | Purpose | When |
-|-----------|------|---------|------|
-| Unit Tests | Vitest | Verify function logic | During development |
-| E2E Tests | Playwright | Verify user flows work | Before deployment |
-| Load Tests | K6 | Verify performance at scale | Scheduled, on-demand |
-
-### Running All Tests
-
-```bash
-# Unit tests (API only)
-pnpm test
-
-# E2E tests (API + Web)
-pnpm test:e2e
-
-# Load tests (new)
-k6 run load-tests/search.k6.js
-
-# All in sequence
-pnpm test && pnpm test:e2e && k6 run load-tests/all-scenarios.k6.js
-```
-
----
-
-## 📈 CI/CD Integration
-
-### GitHub Actions Workflow
-
-Create `.github/workflows/load-test.yml` (template in K6_QUICK_START.md section 🔟):
-
-```bash
-# Runs on schedule (daily at 2 AM)
-# Or manually via workflow_dispatch
-# Reports results as artifacts
-```
-
-### Manual Reporting
-
-```bash
-# Export JSON
-k6 run load-tests/search.k6.js --summary-export=results.json
-
-# View CSV (with extension)
-k6 run load-tests/search.k6.js --out csv=results.csv
-
-# Upload to Grafana Cloud
-K6_CLOUD_TOKEN=xxx k6 run load-tests/search.k6.js --out cloud
-```

-- **Three complementary docs** — Explore different docs for different needs
-- **Executable examples** — K6_QUICK_START.md scripts work as-is
-- **Rate limits matter** — Consider them in test design
-- **Quota gates** — Some operations (listings, payments) are gated by subscription
-- **Test data** — Use seed data or generate unique test users per VU
-- **Production ready** — Guides follow K6 best practices

-## 🔑 Key Implementation Details
-
-### Payment Creation Flow (Backend)
-```
-User clicks "Pay Now"
-  ↓
-Frontend: POST /payments {
-  provider: 'VNPAY',
-  type: 'SUBSCRIPTION',
-  amountVND: 499000,
-  description: 'Agent Pro - Monthly',
-  returnUrl: 'https://goodgo.vn/payment-return',
-  idempotencyKey: UUID  ← Unique per payment attempt
-}
-  ↓
-Backend CreatePaymentHandler:
-  1. Check idempotencyKey (prevent duplicates)
-  2. Validate amount (1 to 100 billion VND)
-  3. Get payment gateway (VNPay/MoMo/ZaloPay)
-  4. Call gateway.createPaymentUrl()
-     - Returns paymentUrl: "https://gateway.com/pay?params..."
-     - Returns providerTxId: "VNP-12345..."
-  5. Mark payment as PROCESSING in DB
-  6. Publish PaymentCreatedEvent
-  7. Return to client: { paymentId, paymentUrl, providerTxId }
-  ↓
-Frontend:
-  window.location = paymentUrl  ← Redirect to gateway
-  ↓
-User completes payment at gateway
-  ↓
-Gateway redirects to returnUrl with callback params
-  ↓
-Backend webhook: POST /payments/callback/vnpay?params...
-  1. Verify callback signature
-  2. Check payment status
-  3. Update payment status in DB
-  4. Publish PaymentCompletedEvent
-  ↓
-PaymentCompletedEvent triggers:
-  - Send email notification
-  - Update user's plan association (eventually)
-  ↓
-Frontend callback handler (if implemented):
-  1. Get paymentId from URL
-  2. Poll GET /payments/{paymentId}
-  3. When status = COMPLETED:
-     - POST /subscriptions { planTier, billingCycle }
-     - Show success message
-     - Redirect to dashboard
-```
-
-### Payment Gateway Implementations
-
-#### VNPay
-```typescript
-// Signature: HMAC SHA-512
-// Request via: URL parameters
-// Response Code: vnp_ResponseCode = '00' means success
-// Transaction ID: vnp_TransactionNo
-```
-
-#### MoMo
-```typescript
-// Signature: HMAC SHA-256
-// Request via: JSON POST body
-// Response Code: resultCode = 0 means success
-// Transaction ID: transId
-```
-
-#### ZaloPay
-```typescript
-// Signature: HMAC SHA-256 (similar to MoMo)
-// Request via: JSON POST body
-// Response Code: return_code = 1 means success
-// Transaction ID: zp_trans_id
-```
-
----
-
-## 🚨 Critical Gaps (What's Missing)
-
-### 1. Checkout Modal/Page ❌
-**What it should do:**
-- Display selected plan details
-- Show monthly vs yearly price
-- Allow payment method selection (VNPay, MoMo, ZaloPay)
-- Show terms & conditions
-- Handle payment creation and redirect
-
-**Current:** CTAs on pricing page link to `/register` instead of starting checkout
-
-### 2. Payment Return Handler ❌
-**What it should do:**
-- Receive redirect from payment gateway
-- Extract payment status from URL/callback
-- Poll payment status via GET /payments/:id
-- Create subscription when payment succeeds
-- Show success/error UI
-
-**Current:** No page exists for this flow
-
-### 3. Subscription Auto-Creation ❌
-**What it should do:**
-- After successful payment, call POST /subscriptions
-- Pass planTier and billingCycle
-- Update user's subscription status
-- Redirect to dashboard
-
-**Current:** Manual process, no UI
-
-### 4. Subscription Management UI ⚠️ Partial
-**What exists:**
-- Payments page shows transaction history
-
-**What's missing:**
-- Subscription status/details page
-- Upgrade/downgrade plan UI
-- Cancel subscription UI
-- Usage/quota display
-
----

-# GoodGo Platform AI — Production Readiness Assessment
-**Date:** April 12, 2026  
-**Project Location:** `/Users/velikho/Desktop/WORKING/goodgo-platform-ai/`
-
----
-
-## Executive Summary
-
-The GoodGo Platform AI project has **MODERATE production readiness**. Core infrastructure (CI/CD, monitoring, backup/restore) is well-documented and partially implemented. However, several critical production items are **incomplete or untested in production**.
-
-**Key Gaps:**
-- SSL/TLS and DNS configuration not deployed (templates only)
-- Penetration testing/security audit not completed
-- CDN setup for static assets not configured
-- E2E test results show failures
-- Performance benchmarks only at framework level (not business logic)
-
----
-
-## Detailed Assessment: 12 Items
-
-### ✅ **1. Load Testing Results** — MODERATE
-**Status:** Scripts exist with baseline results documented  
-**Evidence:**
-- **Path:** `/load-tests/` directory
-  - `scripts/` contains K6 test files: `auth.js`, `listings.js`, `search.js`, `search-advanced.js`, `admin.js`, `mcp.js`, `payments.js`
-  - `results/BASELINE-REPORT.md` — comprehensive baseline report dated 2026-04-09
-  - `results/` contains JSON output files: `auth.json`, `listings.json`, `search.json`, `payments.json`
-
-**What Exists:**
-- ✅ K6 load test suite with 7 test scripts
-- ✅ SLA thresholds defined (p50 < 200ms, p95 < 500ms, p99 < 1s, error rate < 1%)
-- ✅ Baseline results documented with detailed metrics
-- ✅ CI integration via `.github/workflows/load-test.yml`
-
-**What's Missing:**
-- ❌ Production environment test results (only local dev baseline)
-- ❌ Performance regression tracking (should be CI gated)
-- ❌ Historical trend data (no time-series analysis)
-- ❌ Grafana/InfluxDB integration for visualization
-
-**Status Notes:**
-Baseline shows framework-level performance is excellent (p95 latencies < 6ms), but business logic validation blocked by dev environment limitations. Auth and payment endpoints return 500 errors; Typesense unavailable. Recommends re-running against staging with full dependencies.
-
----
-
-### ❌ **2. Security Penetration Test Sign-Off** — MISSING
-**Status:** No formal penetration test or security audit sign-off found  
-**Evidence:**
-- **Path:** `/docs/audits/` contains accessibility and architecture audits, but NO security/penetration testing
-- **CI Security:** `.github/workflows/security.yml` exists with:
-  - Dependency audit (pnpm)
-  - Container scanning (Trivy)
-  - CodeQL SAST analysis
-  - No DAST/pen-test integration
-
-**What Exists:**
-- ✅ Automated dependency vulnerability scanning (pnpm audit, runs on schedule)
-- ✅ Container image scanning (Trivy) for API, Web, AI-services images
-- ✅ Code scanning (CodeQL) for source code vulnerabilities
-- ✅ Security checklist in `docs/deployment.md` (incomplete)
-
-**What's Missing:**
-- ❌ Third-party penetration test report
-- ❌ OWASP Top 10 assessment
-- ❌ Security audit sign-off document
-- ❌ API security testing (DAST)
-- ❌ Web application security scan
-- ❌ Infrastructure security audit
-
-**Recommendation:** Schedule formal pen-test before production launch.
-
----
-
-### ✅ **3. Monitoring Alert Thresholds Configured** — GOOD
-**Status:** Comprehensive alert rules defined and configured  
-**Evidence:**
-- **Path:** `/monitoring/prometheus/alert-rules.yml` (15,969 bytes)
-  - Alert groups defined: `goodgo_api_latency`, `goodgo_database`, `goodgo_redis`, `goodgo_infra`
-  - Per-rule thresholds with severity labels
-  - Dashboard links and runbook URLs embedded
-
-**Specific Alerts Configured:**
-- API latency: p99 > 1s (warning), > 3s (critical)
-- Per-endpoint latency: p99 > 2s
-- 5xx error rate: > 1% for 5 minutes
-- Database: connection pool exhaustion, high query latency
-- Redis: connection failures, high memory
-- Infrastructure: disk space, CPU, memory alerts
-
-**What Exists:**
-- ✅ 15+ alerting rules across API, database, cache, infrastructure
-- ✅ Alert severity labels (warning, critical)
-- ✅ Runbook URLs and dashboard links in annotations
-- ✅ AlertManager configured (`monitoring/alertmanager/alertmanager.yml`)
-- ✅ Prometheus scraping configured (`monitoring/prometheus/prometheus.yml`)
-- ✅ Grafana provisioned with datasources
-
-**What's Missing:**
-- ❌ Alert routing/notification channels not visible (Slack, PagerDuty, email) — likely in secrets
-- ❌ No baseline testing of alert triggers
-- ❌ No alert tuning documentation (what thresholds are based on)
-
----
-
-### ✅ **4. Backup/Restore Verification** — GOOD
-**Status:** Backup procedures documented; automated verification in place  
-**Evidence:**
-- **Path:** `/docs/backup-restore.md` (comprehensive guide, 251 lines)
-- **Path:** `.github/workflows/backup-verify.yml` (automated weekly verification)
-
-**Backup Strategy:**
-- PostgreSQL: Daily at 02:00 UTC via `pg-backup` container (`pg_dump` custom format, compression level 6)
-- Redis: AOF persistence + optional RDB snapshots
-- Typesense: Built-in snapshot API + volume backup
-- Retention: 7 days (default)
-- RTO: ~15 min (local backup), ~30 min (off-site)
-- RPO: ≤ 24 hours
-
-**What Exists:**
-- ✅ Automated backup procedures (cron-based in docker-compose.prod.yml)
-- ✅ Restore procedures documented with step-by-step instructions
-- ✅ Disaster recovery runbook (4 scenarios: DB failure, service crash, full host, data corruption)
-- ✅ Backup verification workflow (GitHub Actions, runs weekly)
-- ✅ Backup integrity checks (`pg_restore --list`)
-- ✅ All three data stores covered (PostgreSQL, Redis, Typesense)
-
-**What's Missing:**
-- ⚠️ Off-site backup storage not documented (where backups are sent)
-- ❌ No tested restore from off-site backup
-- ❌ No documented backup retention policy for off-site storage
-- ⚠️ WAL archiving for point-in-time recovery not mentioned
-
----
-
-### ✅ **5. Incident Response Runbook** — GOOD
-**Status:** Comprehensive runbook exists  
-**Evidence:**
-- **Path:** `/docs/RUNBOOK.md` (41,441 bytes, last updated 2026-04-11)
-
-**Runbook Contents:**
-1. Service Inventory (17 services listed with resource limits, health checks)
-2. Health Checks (application endpoints, verification procedures)
-3. Common Incidents (10 scenarios):
-   - 3.1: Database connection pool exhaustion
-   - 3.2: Redis connection failure
-   - 3.3: Typesense unavailable
-   - 3.4: High API latency
-   - 3.5: Payment callback failures
-   - 3.6: Disk space alerts
-   - 3.7: MinIO / Object storage failure
-   - 3.8: AI services unavailable
-   - 3.9: Log pipeline failure
-   - 3.10: 5xx error rate spike
-4. Recovery Procedures (5 detailed procedures)
-5. Escalation Matrix
-6. Monitoring Dashboards
-7. Useful PromQL Queries
-8. Environment Quick Reference
-
-**What Exists:**
-- ✅ Complete incident response procedures (10+ scenarios)
-- ✅ Step-by-step recovery procedures
-- ✅ Health check commands
-- ✅ Service dependency diagram
-- ✅ Escalation contacts and matrix
-- ✅ PromQL query examples for troubleshooting
-
-**What's Missing:**
-- ⚠️ Escalation matrix not fully visible (contact numbers/Slack channels likely redacted)
-- ❌ No incident log/post-mortem template
-- ❌ No tested drills/runbook exercises
-
----
-
-### ✅ **6. Database Schema Frozen (Migration Lockdown)** — GOOD (Partial)
-**Status:** Migrations exist and organized; migration locking mechanism in place  
-**Evidence:**
-- **Path:** `/prisma/migrations/` (16 migration directories)
-- **Path:** `/prisma/migrations/migration_lock.toml`
-
-**Migrations:**
-```
-20260407165528_init
-20260407210149_add_missing_fk_indexes

-20260411100000_add_pii_encryption_hash_columns
-20260411200000_add_mfa_totp_support (most recent)
-```
-
-**What Exists:**
-- ✅ Migration lock file (`migration_lock.toml`) — prevents provider changes
-- ✅ 16 sequential migrations from 2026-04-07 to 2026-04-11 (recent activity)
-- ✅ CI integration: `pnpm db:migrate:deploy` in GitHub Actions (read-only)
-- ✅ Direct database connection separate from PgBouncer (required for DDL)
-
-**What's Missing:**
-- ⚠️ No documented freeze procedure (how to prevent migrations in production lockdown)
-- ❌ No "production schema freeze" documentation
-- ❌ No tested rollback procedures
-
-**Status Notes:**
-Schema is currently NOT frozen — migrations are active. Recent migrations added encryption, MFA, audit logging. For true production lockdown, would need explicit "no migrations" policy + CI enforcement.
-
----
-
-### ✅ **7. CI/CD Pipeline** — GOOD
-**Status:** Comprehensive CI/CD pipeline configured  
-**Evidence:**
-- **Path:** `.github/workflows/` (9 workflow files)
-
-**Workflows:**
-1. **ci.yml** — Main CI: Lint → Typecheck → Test → Build → E2E (on ubuntu-latest, Node 22)
-   - Services: PostgreSQL (postgis:16-3.4), Redis, Typesense, MinIO
-   - Steps: pnpm install → lint → typecheck → test → build → e2e
-   - E2E uploads Playwright reports as artifacts
-
-2. **e2e.yml** — Separate E2E workflow (deprecated, ci.yml combines)
-   - API + Web E2E tests
-   - Artifact uploads
-
-3. **deploy.yml** — Deployment pipeline
-   - Build & push Docker images to GHCR
-   - Deploy to staging/production (structure visible)

-
-6. **backup-verify.yml** — Automated backup verification
-   - Weekly schedule (Sundays 05:00 UTC)
-   - Manual trigger
-   - Creates backup and runs verification script
-
-7. **codeql.yml** — CodeQL analysis (standard template)
-
-**What Exists:**
-- ✅ Full CI pipeline: lint, typecheck, test, build
-- ✅ E2E testing in CI with artifact uploads
-- ✅ Separate security scanning workflow
-- ✅ Load testing workflow (manual trigger)
-- ✅ Backup verification workflow (weekly)
-- ✅ Docker image building and pushing to GHCR
-- ✅ Concurrency controls to prevent duplicate runs
-- ✅ Service health checks (PostgreSQL, Redis, Typesense, MinIO)
-
-**What's Missing:**
-- ❌ No visible CD (continuous deployment) stage — deploy.yml exists but configuration unclear
-- ⚠️ No SLA gating in CI (e.g., fail if p95 latency > 500ms)
-- ❌ No integration tests between services
-- ❌ No performance regression testing in CI
-
----
-
-### ⚠️ **8. E2E Test Results** — MODERATE
-**Status:** Test suite exists; recent results show failures  
-**Evidence:**

-- `/e2e/web/` — Playwright web UI tests
-
-**Recent Results:**
-- **Report:** `playwright-report/` (generated 2026-04-11 21:46)
-- **Status:** FAILED (`.last-run.json` shows 2 failed tests)
-- **Failed Tests:** 
-  - `72b40b5065e5b60fb5e0-af881f611f09a33bace0`

-- ✅ Playwright HTML report generated
-- ✅ Global fixtures (user creation, database seeding)
-- ✅ CI integration (runs after unit tests pass)
-- ✅ Artifact uploads (reports retained 14 days, traces 7 days)
-- ✅ playwright.config.ts configured
-
-**What's Missing:**
-- ❌ Test failure details not documented (need to inspect report)
-- ❌ Flaky test analysis
-- ❌ Test coverage metrics
-- ❌ SLA validation in E2E tests
-
-**Status Notes:**
-E2E tests are comprehensive but currently failing. Not production-ready until failures are resolved.
-
----
-
-### ❌ **9. Performance Benchmarks Documented** — MISSING
-**Status:** Only framework-level baseline; no business logic benchmarks  
-**Evidence:**
-- **Path:** `/load-tests/results/BASELINE-REPORT.md` (only baseline)
-- **Path:** No dedicated performance benchmark documentation
-
-**What Exists:**
-- ✅ K6 baseline report with latency metrics (p50, p95, p99)

-- ✅ SLA thresholds defined in load-tests/lib/config.js
-
-**What's Missing:**
-- ❌ No documented performance baseline for production (only local dev)
-- ❌ No per-endpoint performance targets
-- ❌ No database query performance benchmarks
-- ❌ No API response time budgets
-- ❌ No historical performance tracking
-- ❌ No performance regression detection
-
-**Status Notes:**
-Load tests blocked by database/dependency issues. Framework responds in < 10ms, but business logic latency unknown.
-
----
-
-### ❌ **10. SSL/TLS Certificates** — NOT CONFIGURED
-**Status:** Configuration templates exist; no production certs deployed  
-**Evidence:**
-- **Path:** `/docker-compose.prod.yml` — no SSL/TLS configuration visible
-- **Path:** `/infra/pgbouncer/pgbouncer.ini` — SSL options commented out:
-  ```
-  ;; client_tls_sslmode = prefer

-## Critical Blockers for Production (Must Fix)
-
-1. **Security Audit** — Conduct penetration test before launch
-2. **E2E Tests** — Fix 2 failing tests
-3. **SSL/TLS Termination** — Deploy reverse proxy with valid certificates
-4. **DNS Setup** — Configure production domains
-5. **Performance Validation** — Run load tests against staging with full dependencies
-
----
-
-## Recommendations (Priority Order)
-
-### P0 (Blocking)
-1. Schedule formal penetration test (3-4 weeks)
-2. Debug and fix E2E test failures
-3. Deploy nginx reverse proxy with Let's Encrypt SSL
-4. Configure DNS for production domains
-5. Run load tests against staging environment
-
-### P1 (Before GA)
-1. Document CDN setup (Cloudflare/CloudFront)
-2. Freeze database schema (implement "no migrations in production" policy)
-3. Document off-site backup storage and restore procedures
-4. Create performance benchmark baselines for all endpoints
-5. Add SLA validation to CI pipeline (fail if p95 > 500ms)
-
-### P2 (Nice-to-have)
-1. Implement DAST/API security scanning in CI
-2. Add performance regression detection to CI
-3. Set up incident log and post-mortem template
-4. Document alert tuning and threshold rationale
-5. Test backup recovery from off-site storage

-## How to Use in Frontend
-
-### Get Plans
-```typescript

-
-export function MyComponent() {
-  const { data: plans, isLoading } = usePlans();
-  
-  return (
-    <div>
-      {isLoading ? 'Loading...' : plans?.map(plan => <div>{plan.name}</div>)}
-    </div>
-  );
-}
-```
-
-### Create Payment
-```typescript
-import { paymentApi } from '@/lib/payment-api';
-import { useMutation } from '@tanstack/react-query';
-
-const createPaymentMutation = useMutation({
-  mutationFn: (payload) => paymentApi.createPayment(payload),

-    idempotencyKey: crypto.randomUUID(),
-  });
-  
-  // Redirect to payment gateway
-  window.location = result.paymentUrl;
-};
-```
-
-### Check Payment Status (on return page)
-```typescript
-import { paymentApi } from '@/lib/payment-api';
-import { useEffect, useState } from 'react';
-
-export function PaymentReturnPage() {
-  const searchParams = new URLSearchParams(window.location.search);

-
-    poll();
-  }, [paymentId]);
-
-  return <div>{status === 'loading' ? 'Processing payment...' : status}</div>;
-}
-```
-
-### Create Subscription
-```typescript
-import { subscriptionApi } from '@/lib/subscription-api';
-
-const result = await subscriptionApi.createSubscription('AGENT_PRO', 'monthly');
-console.log(result);
-// {
-//   subscriptionId: 'cuid...',

-
-| Error | Cause | Solution |
-|-------|-------|----------|
-| `ConflictException: User already has active subscription` | User trying to create 2nd subscription | Check existing subscription first |
-| `ValidationException: Số tiền phải lớn hơn 0` | Amount is 0 or negative | Ensure amount > 0 |
-| `NotFoundException: Plan not found` | Plan tier doesn't exist in DB | Check plan is created and isActive=true |
-| `Payment gateway failed` | Payment gateway credentials wrong | Verify ENV vars |
-| `Cannot complete payment in status X` | Payment already completed/failed | Check idempotencyKey |
-| `Idempotency check failed` | Same idempotencyKey used twice | Generate unique UUID each time |
-
----
-
-## Debugging Checklist
-
-- [ ] Check payment provider credentials in .env
-- [ ] Verify idempotencyKey is unique per request
-- [ ] Ensure amountVND matches plan price
-- [ ] Check returnUrl is publicly accessible
-- [ ] Verify JWT token is valid when calling protected endpoints
-- [ ] Check payment status with `GET /payments/:id`
-- [ ] Review payment provider logs/dashboard
-- [ ] Test with sandbox credentials first

-## 🔍 Document Quality Metrics
-
-| Metric | Value |
-|--------|-------|
-| Analysis depth | Very Thorough |
-| File coverage | 100% of app/web |
-| Code examples provided | Yes (40+ snippets) |
-| Pseudo-code included | Yes |
-| Complexity ratings | Yes (detailed) |
-| Test coverage | Yes |
-| Validation checklist | Yes |
-
-## 📌 Important Notes
-
-1. **No existing i18n:** Everything is hardcoded Vietnamese. This is a greenfield i18n implementation.
-
-2. **A11y is partially done:** Good foundation exists (semantic HTML, ARIA labels, skip link), but focus management and some ARIA attributes are missing.
-
-3. **Technology ready:** All necessary libraries are installed. This is a refactoring/addition project, not a framework change.
-
-4. **TypeScript helps:** Type safety will catch many issues during refactoring.
-
-5. **Testing is important:** Both locales should be tested thoroughly.
-
-## 📚 Additional Resources
-
-The docs reference:
-- Next.js App Router: `/app` directory structure
-- next-intl library: Configuration and setup
-- WCAG 2.1 AA: Accessibility standards

+# Observability — Read-Model / Projector (RFC-003 Phase 0)
+
+Grafana dashboards and wiring notes for the read-model observability stack
+introduced in [GOO-192](/GOO/issues/GOO-192) under [GOO-94](/GOO/issues/GOO-94) §6 Phase 0.
+
+## Metrics
+
+All metrics live in the existing NestJS `metrics/` module
+(`apps/api/src/modules/metrics/`) and are scraped via the standard `/metrics`
+endpoint.
+
+| Metric                                  | Type      | Labels    | Purpose                                                   |
+| --------------------------------------- | --------- | --------- | --------------------------------------------------------- |
+| `read_model_projector_lag_seconds`      | Gauge     | `handler` | Seconds between latest source event and projector cursor. |
+| `read_model_refresh_duration_seconds`   | Histogram | `view`    | Duration of read-model / materialised view refreshes.     |
+| `read_model_reconciliation_drift_total` | Counter   | `model`   | Count of drift discrepancies found during reconciliation. |
+
+### Emit points
+
+Inject `MetricsService` and call:
+
+```ts
+metrics.setProjectorLag(handler, lagSeconds);
+metrics.recordReadModelRefresh(view, durationSeconds);
+metrics.recordReconciliationDrift(model, count?);
+```
+
+## Dashboard
+
+- File: `read-models-dashboard.json` (Grafana schema v38).
+- Import into Grafana (`Dashboards → Import → Upload JSON`), pick the Prometheus
+  data source.
+- Variables: `handler`, `view`, `model` — derived from Prometheus label values.
+- Panels:
+  1. Projector lag by handler (time series + thresholded)
+  2. Max projector lag (stat, RAG 30s / 120s)
+  3. Refresh duration p50/p95 by view
+  4. Refresh throughput (refreshes/sec) by view
+  5. Reconciliation drift rate by model (15m rate)
+  6. Total drift events in last 24h (stat, RAG 1 / 10)
+
+## Local verification
+
+```bash
+pnpm --filter @goodgo/api dev
+curl -s http://localhost:3001/metrics | grep read_model_
+```
+
+All three metric families should appear with `# HELP` / `# TYPE` headers even
+before any samples are recorded.
