f0699436c5 refactor: engineering improvements -- API versioning, structured logging, Alembic, error standardization, test coverage
- API versioning: all REST endpoints prefixed with /api/v1/
- Structured logging: replaced stdlib logging with structlog (console/JSON modes)
- Alembic migrations: versioned DB schema with initial migration
- Error standardization: global exception handlers for consistent envelope format
- Interrupt cleanup: asyncio background task for expired interrupt removal
- Integration tests: +30 tests (analytics, replay, openapi, error, session APIs)
- Frontend tests: +57 tests (all components, pages, useWebSocket hook)
- Backend: 557 tests, 89.75% coverage | Frontend: 80 tests, 16 test files

af53111928 refactor: fix architectural issues across frontend and backend
Address all architecture review findings:

P0 fixes:
- Add API key authentication for admin endpoints (analytics, replay, openapi)
  and WebSocket connections via ADMIN_API_KEY env var
- Add PostgreSQL-backed PgSessionManager and PgInterruptManager for
  multi-worker production deployments (in-memory defaults preserved)

P1 fixes:
- Implement actual tool generation in OpenAPI approve_job endpoint
  using generate_tool_code() and generate_agent_yaml()
- Add missing clarification, interrupt_expired, and tool_result message
  handlers in frontend ChatPage

P2 fixes:
- Replace monkey-patching on CompiledStateGraph with typed GraphContext
- Replace 9-param dispatch_message with WebSocketContext dataclass
- Extract duplicate _envelope() into shared app/api_utils.py
- Replace mutable module-level counter with crypto.randomUUID()
- Remove hardcoded mock data from ReviewPage, use api.ts wrappers
- Remove `as any` type escape from ReplayPage

All 516 tests passing, 0 TypeScript errors.

e0931daece 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

ef6e5ac2be fix: address security findings in Phase 4 analytics and replay
- Fix CRITICAL: use parameterized INTERVAL arithmetic (%(days)s * INTERVAL '1 day')
  instead of string interpolation inside SQL literal
- Use asyncio.gather() for parallel query execution in get_analytics()
- Add range upper bound (max 365 days) to prevent DoS via full-table scans
- Add thread_id validation (alphanumeric, max 128 chars) in replay API
- Sanitize error messages to not reflect user input

33db5aeb10 feat: complete phase 4 -- conversation replay API + analytics dashboard
- Replay models: StepType enum, ReplayStep, ReplayPage frozen dataclasses
- Checkpoint transformer: PostgresSaver JSONB -> structured timeline steps
- Replay API: GET /api/conversations (paginated), GET /api/replay/{thread_id}
- Analytics models: AgentUsage, InterruptStats, AnalyticsResult
- Analytics event recorder: Protocol + PostgresAnalyticsRecorder + NoOp
- Analytics queries: resolution_rate, agent_usage, escalation_rate, cost, interrupts
- Analytics API: GET /api/analytics?range=Xd with envelope response
- DB migration: analytics_events table + conversations column additions
- 74 new tests, 399 total passing, 92.87% coverage
