 Status: completed
 
 DoD:
-- gRPC adapter supports bounded server-stream collection for `window` mode
-- streamed protobuf messages are decoded into normalized JSON items
-- adapter respects item/window limits and upstream timeout
-- runtime dispatches gRPC `window` mode through streaming adapter path
-- local gRPC upstream tests cover success, timeout and malformed method kind handling
+- 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`
