Add an A2A JSON-RPC endpoint with authenticated message/send, message/stream, tasks/get, and tasks/cancel handling. Expose anonymous minimal Agent Cards while keeping the enabled-agent skills list behind existing Bearer authentication.
Bridge inbound calls into the existing agent runtime, add an in-memory task store with duplicate task rejection, JSON-RPC idempotency snapshots, terminal TTL cleanup, and SSE status/artifact event streaming with heartbeat comments.
Add the call_a2a_agent tool and peer adapter with Agent Card discovery fallback, blocking task polling through tasks/get, event-boundary SSE parsing, response caps, timeout limits, redirect refusal, and private-network SSRF protection.
Wire mateclaw.a2a configuration, document deployment settings in English and Chinese, mirror bundled docs, and cover task storage, JSON-RPC validation, card privacy, lifecycle/cancel behavior, SSE parsing, and outbound guardrails with focused tests.
Stopping a conversation previously disposed the outer reactive stream without reliably cancelling synchronous tool callbacks running on worker threads. Shell commands, skill scripts, and Playwright sessions could therefore outlive the visible chat turn.
Propagate cancellation through run-scoped hooks, interrupt active tool execution and parallel batches, terminate subprocess trees, close per-conversation browser sessions, and wait briefly for final stream persistence before acknowledging Stop.
Expose an explicit interrupting state in the chat input to block duplicate stop clicks and show progress, with regression coverage for cancelling an in-flight synchronous tool callback.
