feat: wire frontend pages to live APIs and standardize response contracts (P1)
...
- Backend: Add COUNT query and paginated response shape to conversations endpoint
Returns { conversations: [...], total, page, per_page } instead of flat array
- Frontend: Replace mock data in DashboardPage with fetchAnalytics() API calls
- Frontend: Replace mock data in ReplayListPage with fetchConversations() API calls
- Frontend: Replace mock data in ReplayPage with fetchReplay() API calls
- Add proper loading, empty, and error states to all three pages
- Align ConversationSummary type with actual DB columns (created_at, status)
- Update unit and E2E tests for new paginated conversation response shape
- Add fetchone() to FakeCursor for COUNT query support in E2E tests

fix: restore green builds and align frontend-backend contracts (P0)
...
- Isolate Settings tests from .env and process env leakage
- Fix analytics metadata test to unwrap psycopg Json wrapper
- Remove unused state variables causing frontend build failures
- Fix ReviewPage to use /classifications endpoint instead of nonexistent /result
- Normalize ReviewPage status enums (failed not error) and access_type values
- Align api.ts types with backend response shapes (ReplayPage, AnalyticsData, AgentUsage)

fix: address code and security review findings for Phase 5
...
- Add nginx security headers (X-Frame-Options, X-Content-Type-Options, etc.)
- Fix postgres networking: add to app_network, comment out host port exposure
- Fix rate limit memory leak: add bounded eviction for stale thread entries
- Use immutable update pattern in rate limit check (no .append mutation)
- Extract _VERSION constant to avoid duplicate hardcoded version string

feat: complete phase 5 -- error hardening, frontend, Docker, demo, docs
...
Backend:
- ConversationTracker: Protocol + PostgresConversationTracker for lifecycle tracking
- Error handler: ErrorCategory enum, classify_error(), with_retry() exponential backoff
- Wire PostgresAnalyticsRecorder + ConversationTracker into ws_handler
- Rate limiting (10 msg/10s per thread), edge case hardening
- Health endpoint GET /api/health, version 0.5.0
- Demo seed data script + sample OpenAPI spec
Frontend (all new):
- React Router with NavBar (Chat / Replay / Dashboard / Review)
- ReplayListPage + ReplayPage with ReplayTimeline component
- DashboardPage with MetricCard, range selector, zero-state
- ReviewPage for OpenAPI classification review
- ErrorBanner for WebSocket disconnect handling
- API client (api.ts) with typed fetch wrappers
Infrastructure:
- Frontend Dockerfile (multi-stage node -> nginx)
- nginx.conf with SPA routing + API/WS proxy
- docker-compose.yml with frontend service + healthchecks
- .env.example files (root + backend)
Documentation:
- README.md with quick start and architecture
- Agent configuration guide
- OpenAPI import guide
- Deployment guide
- Demo script
48 new tests, 449 total passing, 92.87% coverage

feat: complete phase 1 -- core framework with chat loop, agents, and React UI
...
Backend:
- FastAPI WebSocket /ws endpoint with streaming via LangGraph astream
- LangGraph Supervisor connecting 3 mock agents (order_lookup, order_actions, fallback)
- YAML Agent Registry with Pydantic validation and immutable configs
- PostgresSaver checkpoint persistence via langgraph-checkpoint-postgres
- Session TTL with 30-min sliding window and interrupt extension
- LLM provider abstraction (Anthropic/OpenAI/Google)

- Security: no hardcoded defaults, startup API key validation, no input reflection
Frontend:
- React 19 + TypeScript + Vite chat UI
- WebSocket hook with reconnect + exponential backoff
- Streaming token display with agent attribution
- Interrupt approval/reject UI for write operations
- Collapsible tool call viewer
Testing:
- 87 unit tests, 87% coverage (exceeds 80% requirement)
