 ## 2. Các Tính Năng Đang Hoàn Thiện (In-Progress/Partial)
 ### **Incomplete Modules**
 | Module | Path | Issue | Details |
 |--------|------|-------|---------|
 | **Health** | `apps/api/src/modules/health/` | ⚠️ Presentation-only | Controller + infrastructure only, missing domain/application |
 | **Metrics** | `apps/api/src/modules/metrics/` | ⚠️ Presentation-only | Prometheus export only, missing CQRS/domain |
 | **MCP** | `apps/api/src/modules/mcp/` | ⚠️ Presentation-only | Transport controller only (~50 LOC), stub implementations |
 | **Shared** | `libs/shared/` | ⚠️ Partial | Domain primitives + infrastructure, no application/presentation |
 ### **Known TODOs & Technical Debt**
 - `admin/application/services/system-settings.service.ts`: "TODO(hardening): secret values as plain strings" — needs encryption
 - No TOTP MFA enforcement for Agent/Admin roles
 - No field-level PII encryption (email, phone cleartext)
 - MCP server implementations ~50 LOC each — need full handlers + tests
 - 27 rate-limit guard tests failing (TEC-1918)
 - 6 web unit tests vs. 52 page routes (coverage gap)
 ---
 ## 3. Các Tính Năng Còn Thiếu (Missing)
 | Feature | Reference | Status |
 |---------|-----------|--------|
 | **Advanced MCP Handlers** | `libs/mcp-servers/` | 🔴 Stub implementations only |
 | **PII Field Encryption** | Admin, utils | 🔴 Schema exists, no crypto layer |
 | **TOTP MFA Enforcement** | User.totpSecret | 🔴 Schema + endpoints, no guard middleware |
 | **Listing 404 Handling** | TEC-1650 | 🟡 Returns 500 instead |
 | **Audit Log for Admin** | TEC-1657 | 🟡 No structured trail |
 | **Rate Limiting Tests** | TEC-1656 | 🟡 27 test failures |
 | **ESLint Errors** | TEC-1893 | 🔴 725 errors (712 auto-fixable) |
 | **TypeScript Test Errors** | TEC-1918 | 🔴 7 errors (missing vitest types) |
 ---
 ## 4. Các Tính Năng Sẽ Phát Triển Trong Tương Lai (Future Roadmap)
 ### **Wave 13-14 (Current)**
 | Task | Priority | Target |
 |------|----------|--------|
 | TEC-1918 | Fix 725 ESLint + 7 TS errors | P0 |
 | TEC-1889 | Fix 27 rate-limit test failures | P0 |
 | TEC-1890 | Complete health/metrics/mcp DDD | P0 |
 | TEC-1891 | Real MCP server handlers | P1 |
 | TEC-1892 | Add 50+ web unit tests | P1 |
 | TEC-1893 | PII field-level encryption | P1 |
 | TEC-1894 | Enforce TOTP for Agent/Admin | P1 |
 | TEC-1650 | Fix listing detail 404 | P0 |
 ### **Post-Wave 14**
 1. **Performance:** Advanced caching, connection pooling optimization, indexed queries
 2. **Features:** Virtual tours, live chat, blockchain ledger, multi-language expansion
 3. **Market Intelligence:** ML model enhancement, trend forecasting, micro-analytics
 4. **Regulatory:** GDPR compliance, Vietnam KYC workflows, digital signatures

 # Contract API – Chỉ số Thị trường & Ticker (Goodgo Platform AI)
 > Liên quan: [TEC-3036](/TEC/issues/TEC-3036), [TEC-3042](/TEC/issues/TEC-3042), [TEC-3043](/TEC/issues/TEC-3043).
 > Trạng thái: Draft v1 (chờ CTO + BE TechLead + FE TechLead duyệt).
 > Chủ trì: API Architect. Phối hợp: Database Architect, Backend TechLead, Frontend TechLead.
 Tài liệu này định nghĩa contract cho các endpoint mới phục vụ UI phong cách "sàn giao dịch" (trading-floor) của Goodgo Platform AI. Frontend **chỉ gọi API thực**, cấm mock. Các endpoint mới được thêm **không breaking** endpoint hiện có (`/analytics/*`, `/listings/*`, `/search/*`).
 ## 1. Nguyên tắc thiết kế
 - **Base path**: `/api/v1/` (prefix chung toàn platform, bearer JWT khi cần).
 - **Auth**: Public cho các chỉ số tổng hợp (cache-able). JWT cho các API cá nhân hoá (watchlist ticker).
 - **Caching**: `Cache-Control: public, max-age=30, stale-while-revalidate=60` cho chỉ số ticker. `max-age=300` cho heatmap/price-trends.
 - **Đơn vị**:
  - Tiền tệ: `VND` (integer, không thập phân). Field nào dùng VND/m² phải ghi rõ `unit: "VND_PER_SQM"`.
  - Thời gian: ISO-8601 UTC (`2026-04-21T03:15:00Z`). Client tự chuyển sang Asia/Ho_Chi_Minh.
  - % change: `number` (phần trăm, ví dụ `2.35` = `+2.35%`). `delta` là giá trị tuyệt đối cùng đơn vị với `value`.
 - **Response envelope**: thống nhất với module analytics hiện có:
  ```json
  {
    "data": { ... },
    "meta": {
      "generatedAt": "2026-04-21T03:15:00Z",
      "ttlSeconds": 30,
      "source": "aggregation_v1",
      "baselinePeriod": "PT24H"
    }
  }
  ```
 - **Lỗi**: tuân theo `docs/api-error-codes.md` (ErrorResponse `{ code, message, details }`).
 - **Pagination** (nếu có): `page`, `pageSize` (max 100), response có `meta.pagination`.
 - **i18n**: label/description phục vụ UI trả về tiếng Việt; field system (`code`, `slug`) dùng tiếng Anh.
 ## 2. Phân loại endpoint
 | Nhóm | Mục đích UI | Cache | Auth |
 |------|-------------|-------|------|
 | Market Index | Header chỉ số GGI/khu vực | 30s | Public |

 |----------|-------|-------------------|---------|
 | `market-index` | `Listing`, `Transaction`, `PriceSnapshot` | Weighted avg price/m² chuẩn hoá về base 2025-01-01 = 1000 | 1 phút (materialized view) |
 | `price-trends` | `PriceSnapshot` (daily), `Listing.price_history` | OHLC theo bucket | 5 phút |
 | `district-volume` | `Listing.createdAt`, `Inquiry`, `Transaction` | COUNT + window function | 1 phút |
 | `listings/ticker` | Redis stream `listings:events` + DB fallback | Event bus (create/price_change/feature) | real-time |
 | `top-movers` | `PriceSnapshot` | % change theo bucket + ranking | 5 phút |
 | `heatmap-summary` | `Listing` + `District`/`H3Cell` precomputed | PostGIS aggregate theo polygon/H3 | 15 phút |
 Database Architect xác nhận: (i) thêm materialized views `mv_market_index_*`, `mv_price_snapshot_*`; (ii) Redis stream `listings:events` dùng cho ticker/SSE; (iii) bảng `H3Cell` cho heatmap r7/r8.
 ## 5. Phân việc cho Backend TechLead ([TEC-3042](/TEC/issues/TEC-3042))
 | Endpoint | Đề xuất cấp độ BE | Ghi chú |
 |----------|-------------------|--------|
 | `market-index` | Senior | Cần design materialized view + cache invalidation |
 | `price-trends` | Middle | Query trên view sẵn có |
 | `district-volume` | Middle | Window function + Redis cache |
 | `listings/ticker` (REST+SSE) | Senior | Pub/sub, backpressure, auth watchlist |
 | `top-movers` | Middle | Dựa trên view price-trends |
 | `heatmap-summary` | Senior | PostGIS + H3, geojson ref |
 | DTO/OpenAPI sync | Junior | Viết DTO, Swagger decorators, update `docs/api-endpoints.md` |
 ## 6. OpenAPI & Swagger
 - DTO mới ở `apps/api/src/modules/analytics/presentation/dto/` và `apps/api/src/modules/listings/presentation/dto/` (ticker).
 - Controller:
  - `analytics.controller.ts`: thêm `@Get('market-index')`, `@Get('price-trends')`, `@Get('district-volume')`, `@Get('top-movers')`, `@Get('heatmap-summary')`.
  - `listings.controller.ts`: thêm `@Get('ticker')`, `@Get('ticker/stream')`.
 - Tag Swagger: `Analytics - Market`, `Listings - Ticker`.
 - Cập nhật `docs/api-endpoints.md` (phần Analytics & Listings) sau khi merge.
 ## 7. Versioning & rollout
 - Tất cả endpoint mới nằm dưới `/api/v1/` hiện tại — **không bump major**.
 - Feature flag (nếu cần) dùng `FEATURE_MARKET_TICKER` cho ticker SSE.
 - SLO: p95 < 250ms cho REST; SSE duy trì kết nối ≥ 5 phút, heartbeat 15s.
 ## 8. Checklist duyệt
 - [ ] CTO phê duyệt phạm vi & SLO.
 - [ ] BE TechLead xác nhận phân rã task & timeline.
 - [ ] FE TechLead xác nhận response schema đủ cho UI sàn giao dịch.
 - [ ] Database Architect ký nguồn dữ liệu & materialized views.
 - [ ] DTO/OpenAPI/Swagger & `docs/api-endpoints.md` cập nhật.
