 DoD:
-- session and async_job tool families are published in the MCP tool catalog
-- generated `start/poll/stop` and `start/status/result/cancel` tool calls work through JSON-RPC
-- stream sessions and async jobs are persisted with explicit status transitions
-- session and async_job tool calls are logged through observability
-- MCP integration tests cover `session start -> poll -> stop` and `async job start -> status -> result`
+- local fixture stack includes:
+  - REST SSE server
+  - gRPC server-streaming server
+  - WebSocket event server
+- Playwright covers:
+  - REST window flow
+  - gRPC streaming flow
+  - session tool flow
+  - async job flow
