 3. Store completed delegation results for the agent to pick up
 
 Resilient: recreates HTTP client on failure, auto-restarts on crash.
+
+Fix #354 (auto-resume after async A2A delegations): when multiple
+delegate_task calls fire in parallel and exceed the per-turn timeout,
+the claude-code subprocess ends before results arrive. The proxy-path
+results are now stored with method='delegate_result' (fix #376 /
+a2a_proxy_helpers.go logA2ADelegationResult), so _check_delegations
+finds them on the next heartbeat tick and sends a self-message to
+wake the agent with the results.
