test: add routing integration tests for Phase 2 test requirements
...
9 tests covering the complete multi-agent routing flow:
- Single-intent routing to each agent (order_lookup, order_actions, discount, fallback)
- Multi-intent routing hint injection for sequential execution
- Ambiguity detection skips graph and returns clarification
- Low confidence threshold triggers ambiguity
- No-classifier fallback to supervisor prompt routing
Fills Phase 2 test requirement for integration-level routing coverage.
Total: 197 tests, 92.60% coverage.

test: add Phase 2 checkpoint acceptance tests
...
18 integration tests validating all 7 Phase 2 checkpoint criteria:
1. Order query routes to order_lookup agent
2. Multi-intent classification with routing hint injection
3. Ambiguous message triggers clarification prompt
4. 30-min interrupt TTL auto-cancel with retry prompt
5. Webhook POST escalation with retry on failure
6. E-commerce template loads 4 correctly configured agents
7. Coverage at 92.60% (188 tests total)

test: add integration tests for WebSocket message flow
...
17 integration tests covering:
- Happy path: token streaming, tool calls, multi-message sessions
- Interrupt flow: approve and reject paths with manager tracking
- Session TTL: expiration, sliding window reset, interrupt extension
- Validation: invalid JSON, missing fields, size limits
- Interrupt TTL: expired interrupt sends retry prompt
Fills Phase 1 test gap for integration-level WebSocket coverage.
Total: 170 tests, 92.15% 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)

- Input validation: message size cap, thread_id format, content length
- 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)
- Ruff lint + format clean
Infrastructure:
- Docker Compose (PostgreSQL 16 + backend)
