Closes three CSRF security gaps identified in code review:
1. Added X-CSRF-Token and X-Workspace-Id to CORS allowed headers
- Updated apps/api/src/main.ts to accept CSRF token headers
2. Integrated CSRF token handling in web client
- Added fetchCsrfToken() to fetch token from API
- Store token in memory (not localStorage for security)
- Automatically include X-CSRF-Token in POST/PUT/PATCH/DELETE
- Implement automatic token refresh on 403 CSRF errors
- Added comprehensive test coverage for CSRF functionality
3. Applied CSRF Guard globally
- Added CsrfGuard as APP_GUARD in app.module.ts
- Verified @SkipCsrf() decorator works for exempted endpoints
All tests passing. CSRF protection now enforced application-wide.

Implements comprehensive rate limiting on all webhook and coordinator endpoints
to prevent DoS attacks. Follows TDD protocol with 14 passing tests.
Implementation:
- Added @nestjs/throttler package for rate limiting
- Created ThrottlerApiKeyGuard for per-API-key rate limiting
- Created ThrottlerValkeyStorageService for distributed rate limiting via Redis
- Configured rate limits on stitcher endpoints (60 req/min)
- Configured rate limits on coordinator endpoints (100 req/min)
- Higher limits for health endpoints (300 req/min for monitoring)
- Added environment variables for rate limit configuration
- Rate limiting logs violations for security monitoring
Rate Limits:
- Stitcher webhooks: 60 requests/minute per API key
- Coordinator endpoints: 100 requests/minute per API key
- Health endpoints: 300 requests/minute (higher for monitoring)
Storage:
- Uses Valkey (Redis) for distributed rate limiting across API instances
- Falls back to in-memory storage if Redis unavailable
Testing:
- 14 comprehensive rate limiting tests (all passing)
- Tests verify: rate limit enforcement, Retry-After headers, per-API-key isolation
- TDD approach: RED (failing tests) → GREEN (implementation) → REFACTOR
Additional improvements:
- Type safety improvements in websocket gateway
- Array type notation standardization in coordinator service

Add CoordinatorIntegrationModule providing REST API endpoints for the Python
coordinator to communicate with the NestJS API infrastructure:
- POST /coordinator/jobs - Create job from coordinator webhook events
- PATCH /coordinator/jobs/:id/status - Update job status (PENDING -> RUNNING)
- PATCH /coordinator/jobs/:id/progress - Update job progress percentage
- POST /coordinator/jobs/:id/complete - Mark job complete with results
- POST /coordinator/jobs/:id/fail - Mark job failed with gate results
- GET /coordinator/jobs/:id - Get job details with events and steps
- GET /coordinator/health - Integration health check
Integration features:
- Job creation dispatches to BullMQ queues
- Status updates emit JobEvents for audit logging
- Completion/failure events broadcast via Herald to Discord
- Status transition validation (PENDING -> QUEUED -> RUNNING -> COMPLETED/FAILED)
- Health check includes BullMQ connection status and queue counts
Also adds JOB_PROGRESS event type to event-types.ts for progress tracking.

- Integrated BetterAuth library for modern authentication
- Added Session, Account, and Verification database tables
- Created complete auth module with service, controller, guards, and decorators
- Implemented shared authentication types in @mosaic/shared package
- Added comprehensive test coverage (26 tests passing)
- Documented type sharing strategy for monorepo
- Updated environment configuration with OIDC and JWT settings
Key architectural decisions:
- BetterAuth over Passport.js for better TypeScript support
- Separation of User (DB entity) vs AuthUser (client-safe subset)
- Shared types package to prevent FE/BE drift
- Factory pattern for auth config to use shared Prisma instance
Ready for frontend integration (Issue #6).
