# 2025-12-06 P2 Implementation Summary
|
|
|
|
**Date:** 2025-12-06
|
|
**Status:** ✅ P2 Complete
|
|
**Objective:** Enhance Security and Documentation
|
|
|
|
## Executive Summary
|
|
This session focused on completing Priority 2 (P2) tasks for the Backend v1.4.3. All P2 objectives were met, including API documentation, secure session management, observability, and API hardening.
|
|
|
|
**Note:** While P2 features are complete and verified by code review, the `pnpm build` process is currently failing due to pre-existing issues in P0 modules (Casl Ability & Workflow DSL) that were outside the scope of this session. These build errors must be addressed in the next session (P0 Urgent).
|
|
|
|
## Completed Tasks
|
|
|
|
### ✅ P2-1: Swagger API Documentation
|
|
- **Objective:** Improve API discoverability.
|
|
- **Changes:**
|
|
- Configured `SwaggerModule` at `/docs`.
|
|
- Added full documentation for `AuthController`, `CorrespondenceController`, `RfaController`, and `UserController`.
|
|
- Decorated DTOs with `@ApiProperty` for schema clarity.
|
|
|
|
### ✅ P2-2: Refresh Token Mechanism
|
|
- **Objective:** Secure session management implementation (ADR-016).
|
|
- **Changes:**
|
|
- Created `RefreshToken` entity (hashed tokens).
|
|
- Implemented `AuthService` logic for:
|
|
- **Token Generation:** Access (15m) + Refresh (7d).
|
|
- **Storage:** Hashed in DB.
|
|
- **Rotation:** Refresh token reuse triggers rotation.
|
|
- **Revocation:** Security mechanism to invalidate stolen token families.
|
|
- Exposed `POST /auth/refresh` endpoint.
|
|
|
|
### ✅ P2-3: Prometheus Metrics
|
|
- **Objective:** System observability.
|
|
- **Changes:**
|
|
- Integrated `@willsoto/nestjs-prometheus` and opened `/metrics`.
|
|
- Implemented standard metrics (CPU, Memory).
|
|
- Added custom HTTP metrics (`http_requests_total`, `http_request_duration_seconds`) via `PerformanceInterceptor`.
|
|
- Refactored `MonitoringModule` for modularity.
|
|
|
|
### ✅ P2-4: Rate Limiting & Security Headers
|
|
- **Objective:** API Hardening.
|
|
- **Changes:**
|
|
- **Throttler:** Verified global rate limit (100/min) and strict login limit (5/min).
|
|
- **Helmet:** Configured Security Headers with custom CSP to support Swagger UI.
|
|
- **CORS:** Dynamic configuration connected to `ConfigService`.
|

## Known Issues (P0 - Urgent)
|
|
|
|
The following build errors were identified but deferred as they belong to P0 scope:
|
|
|
|
1. **AbilityFactory (CASL):** TypeScript mismatch in Permission loops (`CASL integration`).
|
|
2. **WorkflowEngine (DSL):** TypeScript mismatch in Zod Schema validation (`WorkflowParser`).
|
|
|
|
**Action Plan:** These must be fixed immediately in the next session to restore build stability.
