+# GoodGo Platform
+
+Vietnamese real estate platform — monorepo powered by pnpm workspaces + Turborepo.
+
+## Quick Start
+
+```bash
+pnpm install
+pnpm db:generate        # Generate Prisma client
+pnpm db:migrate:dev     # Run migrations (needs PostgreSQL 16 + PostGIS)
+pnpm db:seed            # Seed sample data (users, listings, districts)
+pnpm dev                # Start all apps (API :3001, Web :3000)
+```
+
+## Architecture
+
+- **apps/api** — NestJS backend (CQRS, DDD, clean architecture)
+- **apps/web** — Next.js 15 frontend (App Router, Tailwind, Zustand)
+- **libs/ai-services** — Python FastAPI AI/ML services (AVM, content moderation, NLP)
+- **libs/mcp-servers** — MCP tool server library (property search, analytics, valuation)
+- **prisma/** — Schema, migrations, seed scripts
+- **e2e/** — Playwright E2E tests (API + Web projects)
+
+## Key Commands
+
+| Command | Description |
+|---------|-------------|
+| `pnpm lint` | ESLint (auto-fixable with `--fix`) |
+| `pnpm typecheck` | TypeScript type checking |
+| `pnpm test` | Unit tests via Vitest (API only) |
+| `pnpm build` | Production build (all packages) |
+| `pnpm test:e2e` | Playwright E2E tests |
+| `pnpm db:studio` | Prisma Studio GUI |
+
+## Tech Stack
+
+- **Runtime**: Node.js >= 22, pnpm 10
+- **Backend**: NestJS, Prisma ORM, PostgreSQL 16 + PostGIS, Redis
+- **Frontend**: Next.js 15, React 18, Tailwind CSS 3, Zustand, Mapbox GL
+- **Testing**: Vitest (unit), Playwright (E2E)
+- **CI**: GitHub Actions (lint → typecheck → test → build)
+
+## Project Structure (API)
+
+```
+apps/api/src/modules/
+  auth/          — Authentication (JWT, OAuth, refresh tokens, CSRF)
+  listings/      — Property listings CRUD
+  payments/      — VNPay, MoMo, ZaloPay payment integration
+  subscriptions/ — Plans, quotas, usage tracking
+  admin/         — Moderation, KYC, user management, audit logs
+  analytics/     — Market data, heatmaps, price trends, AVM
+  search/        — Geo search, full-text search (Typesense), saved searches
+  notifications/ — Email, in-app notifications
+  agents/        — Agent profiles, quality scores
+  inquiries/     — Property inquiry management
+  leads/         — Lead tracking and conversion
+  reviews/       — Property reviews and ratings
+  health/        — Liveness and readiness probes
+  metrics/       — Prometheus metrics, web vitals
+  mcp/           — MCP tool server endpoints
+  shared/        — Domain primitives, guards, pipes, logging
+```
+
+Each module follows DDD layers: `domain/` → `application/` → `infrastructure/` → `presentation/`.
+
+## Project Structure (Libs)
+
+```
+libs/
+  ai-services/     — Python FastAPI AI/ML services (AVM, content moderation, NLP)
+  mcp-servers/     — MCP tool server library (property search, analytics, valuation)
+```
+
+## Database
+
+- PostgreSQL 16 with PostGIS extension for geospatial queries
+- 22 models (User, Property, Listing, Payment, Subscription, etc.)
+- Migrations in `prisma/migrations/`
+- Seed data covers: users, agents, Ho Chi Minh City districts/wards, sample properties, subscription plans
+
+## Environment Variables
+
+Required in `.env`:
+- `DATABASE_URL` — PostgreSQL connection string
+- `JWT_SECRET`, `JWT_REFRESH_SECRET` — Auth tokens
+- `VNPAY_*` — Payment gateway config
+- `MAPBOX_TOKEN` — Map rendering (frontend)
+- `REDIS_URL` — Cache layer (optional for dev)
+
+## Conventions
+
+- Import order enforced by eslint-plugin-import-x (external → internal → relative)
+- Path aliases: `@modules/*` in API, `@/*` in Web
+- Vietnamese UI text throughout (property types, districts, currency in VND)
+- All handlers return typed `Result<T>` or throw `DomainException`
+- Commit messages follow conventional commits

 # Hướng Dẫn Đóng Góp
 
+## Kỷ Luật Commit & Push (Bắt Buộc)
+
+> 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)).
+
+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.
+
+### 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 Trình Git & Branching
+
+### Nhánh Chính
+
+| Nhánh | Mục đích | Protected |
+|-------|---------|-----------|
+| `main` / `master` | Production branch — stable releases | ✅ Yes |
+| `develop` | Development branch — integration point | ✅ Yes |
+| `feature/*` | Feature branches — phát triển tính năng mới | ❌ No |
+| `fix/*` | Bug fix branches | ❌ No |
+| `docs/*` | Documentation updates | ❌ No |
+| `refactor/*` | Code refactoring, cleanup | ❌ No |
+
+### Quy Trình Tạo Feature Branch
+
+```bash
+# 1. Cập nhật branch chính
+git checkout develop
+git pull origin develop
+
+# 2. Tạo feature branch
+git checkout -b feature/awesome-feature
+
+# Naming convention:
+# feature/user-authentication
+# fix/csrf-middleware-double-middleware
+# docs/api-documentation
+# refactor/remove-dead-code
+```
+
+### Pull Request Workflow
+
+```bash
+# 1. Commit changes
+git add .
+git commit -m "feat(auth): implement phone OTP login"
+
+# 2. Push to origin
+git push origin feature/awesome-feature
+
+# 3. Open PR on GitHub
+# - Title: Short summary (max 70 chars)
+# - Description: Why, what changed, how to test
+# - Link related issues: Fixes #GOO-7
+# - Request reviewers: team lead, domain expert
+
+# 4. Address review feedback
+git add .
+git commit -m "refactor(auth): address PR feedback"
+git push
+
+# 5. Merge when approved
+# - Squash commits if many small fixes
+# - Delete branch after merge
+```
+
+### Protected Branch Rules
+
+`main` và `develop` branches yêu cầu:
+
+- ✅ All CI checks pass (lint, typecheck, test, build)
+- ✅ 1 approval từ code owner
+- ✅ Dismiss stale PR approvals
+- ✅ Branches must be up to date before merge
+- ❌ Force push không được phép

+# 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.

+# Analytics Module
+
+Vietnamese real estate analytics endpoints: market reports, price trends, heatmaps, district stats, AVM (property valuation), neighborhood scores, POIs, AI-powered listing/project advice.
+
+---
+
+## Cache Metadata Pattern
+
+All `/analytics/*` and `/avm/*` responses are **automatically wrapped** by `CacheMetaInterceptor` with a `cacheMeta` field that tells the frontend how fresh the data is.
+
+### Response shape
+
+```json
+{
+  "data": { /* original payload */ },
+  "cacheMeta": {
+    "cachedAt": "2026-04-21T10:00:00.000Z",
+    "nextRefreshAt": "2026-04-21T10:15:00.000Z",
+    "source": "cache"
+  }
+}
+```
+
+| Field | Type | Description |
+|---|---|---|
+| `cachedAt` | `string \| null` | ISO-8601 timestamp when the cache entry was written. `null` for legacy entries or when Redis is unavailable. |
+| `nextRefreshAt` | `string \| null` | ISO-8601 timestamp when the entry will expire. Computed as `cachedAt + ttlSeconds`. `null` when `cachedAt` is null. |
+| `source` | `"cache" \| "fresh"` | `"cache"` = data served from Redis; `"fresh"` = freshly fetched from DB/AI. |
+
+### Frontend usage
+
+Use `cacheMeta` to show a "Cập nhật lúc..." badge or tooltip:
+
+```tsx
+const label = cacheMeta.cachedAt
+  ? `Cập nhật lúc ${new Date(cacheMeta.cachedAt).toLocaleTimeString('vi-VN')}`
+  : 'Dữ liệu mới nhất';
+```
+
+### How it works (for backend devs)
+
+Three components cooperate:
+
+1. **`CacheMetaStore`** (`shared/infrastructure/cache-meta.store.ts`)  
+   An `AsyncLocalStorage<{ meta: CacheMeta | null }>` that lives for the duration of a single HTTP request. Provides request isolation so concurrent requests never share metadata.
+
+2. **`CacheService.getOrSet`** (`shared/infrastructure/cache.service.ts`)  
+   Cache entries are now stored as JSON envelopes `{ __v: data, cachedAt, ttlSeconds }`.  
+   On each call, `getOrSet` writes the resolved metadata into the ALS store:
+   - **Cache hit** → reads `cachedAt`/`ttlSeconds` from the stored envelope, computes `nextRefreshAt`, writes `source: "cache"`.
+   - **Cache miss / fresh** → writes `cachedAt = now`, computes `nextRefreshAt`, writes `source: "fresh"`.
+   - **Redis unavailable** → writes `{ cachedAt: null, nextRefreshAt: null, source: "fresh" }`.
+
+3. **`CacheMetaInterceptor`** (`analytics/presentation/interceptors/cache-meta.interceptor.ts`)  
+   Applied at controller class level via `@UseInterceptors(CacheMetaInterceptor)`.  
+   Wraps each response with the ALS-sourced `cacheMeta` after the handler resolves.
+
+### Adding the pattern to a new controller
+
+```ts
+import { UseInterceptors } from '@nestjs/common';
+import { CacheMetaInterceptor } from '../interceptors/cache-meta.interceptor';
+
+@UseInterceptors(CacheMetaInterceptor)
+@Controller('my-endpoint')
+export class MyController { ... }
+```
+
+No other changes needed — `CacheService.getOrSet` handles metadata population automatically.
+
+### Legacy cache entries
+
+Entries written by previous versions of `CacheService` (plain JSON, no `__v` envelope) are still served correctly. `cacheMeta` will have `cachedAt: null` and `nextRefreshAt: null` for these entries.
