Worker exit codes:

  • R21-O5: gateway death surfaces as EndOfStream and exits 6 (ProtocolViolation) instead of 5.
  • R21-O6: event-queue overflow exits as generic UnexpectedFailure (1).

Source: archreview/2026-10-21/remediation/00-tracking.md row R21-O5, R21-O6 (cycle-1 WRK-17, WRK-18)

Next step (from the tracker): O5: map EndOfStream to PipeConnectionFailed with a WorkerApplicationTests case. O6: add a dedicated exit code (7 is now used for unhandled exceptions, so use 8) and update the overflow paragraph of docs/MxAccessWorkerInstanceDesign.md.

Current-state evidence: the row is still Open/Deferred in the latest (2026-10-21) tracker, and a code check on local main @ 8c0a51d (2026-11-06) found it still present unless noted below.
