There was a problem hiding this comment.
Validated the exact-head early-close fix. A permanent close before root coordinator completion now rejects instead of silently returning empty or partial output, while API errors retain priority and successful coordinator completion still exits normally. The regression coverage exercises clean and abrupt closure, partial output, child-only completion, success ordering, cleanup, and close-reason privacy. Review is complete; ecosystem CI is still running.

Summary
The multi-agent WebSocket example ignores iterator
closemessages. A clean or abrupt server close before the coordinator finishes therefore resolvesmain()successfully, potentially leaving only an empty or partial answer.Add a three-line guard that rejects permanent closure before coordinator completion. Preserve the existing error-first handling, successful-completion break, and
finallycleanup. The error is deliberately generic and does not expose the server's close reason or unsent payloads. Reconnection uses different iterator events and is unaffected.Only the handwritten example and its existing test harness change; both are absent from the pinned Castiron generated snapshot. No SDK/generated code, dependencies, parsing, retries, or timeouts change. Open PRs were checked and none addresses this example's early-close behavior.
Regression coverage and validation
ResponsesWS, and a synthetic loopback server: clean/abrupt early closure incorrectly resolved successfully../scripts/test tests/lib/multi-agent-websocket-example.test.ts tests/lib/websocket-example-close.test.ts tests/lib/responsesWebSocket.test.ts.tsc --noEmit, pinned Oxfmt 0.62.0, available Oxlint 1.76.0, andgit diff --checkpassed.Local tests used cached Vitest 4.1.10 and Oxlint 1.76.0 instead of the repository's 4.1.11/1.79.0 pins. Fresh frozen installation remains blocked by missing publication-time metadata for
qs@6.16.0in the configured registry; no safeguards or configuration were changed. Repository CI will verify the pinned toolchain.Adversarial self-review
Reviewed permanent-close versus reconnect semantics, completion/close ordering, API-error priority, child-agent completion, partial output, cleanup, privacy, and minimum-runtime compatibility. Tightened the regression coverage for API-error-before-close, then repeated review and verification. No actionable issues remain.
