Summary

Why abandon

The failed-export timeout was seen twice, on 2026-10-13 (#5458, #5481), at a load average near 47. Since then, an_export_failure_with_the_broadcast_up_exits_without_lingering and a_drop_exits_one_once_the_linger_expires pass alone and under 40 bounded CPU workers, so the quest's first step ("reproduce and record the failed bound") cannot be completed. The real-process exit-code tests stay in place with their bounds unchanged, so a recurrence fails loudly and gets a fresh quest with that evidence.

Validation

  • just check
  • quest check
  • the two moq-cli::export tests above: passed alone and under 40 bounded CPU workers

Public API

None.

Wire impact

None.

Walkthrough

The Required list no longer includes the Export exit tests quest. The export-failure planning document is deleted. The load observation in the auth-serve signals document no longer links the results to the export-failure issue; it still records that each test timed out and passed alone.

Priority: ⬇️ Low

Merge Risk: ⚪ Minimal · up to 005c1

The unreproducible quest is removed from required tracking while the export tests remain. Tracked documentation navigation is valid, and no concrete merge-blocking risk was identified.

The separate historical failed-export timing failure remains open. On current
main `0fc797747`, both named tests passed before these fixture changes under a
loaded host (about 32): failed-export exited in 2.285 s and the interrupted
case in 4.787 s. Those passes do not identify or resolve the historical cause.
Reproduce and record the failed bound and process before changing that arm.

P2 Badge Keep the unresolved failed-export flake open

The cited reason for closing this quest does not resolve the tracked failure: #5561 only adapted the already-existing paused-clock Follower test to the new export constructor, while this deleted section explicitly records that repeated load passes did not identify the historical real-process timeout's failed bound or root cause. Removing the quest therefore loses the sole tracker for a flake involving subprocess startup, relay connection, catalog reading, and process exit; keep it open until that failure is reproduced and explained.

You're right that #5561 didn't resolve this. It only adapted the existing Follower test (from #5147), so I've removed that claim from the PR. The maintainer chose to abandon the quest as unreproducible, not resolved. Since it was seen on 2026-10-13, both tests pass alone and under 40 bounded CPU workers, so the quest's required first step (reproduce and record the failed bound and process) can't be completed. The real-process tests keep their bounds, so a recurrence fails loudly and gets a fresh quest with that evidence instead of an open tracker with nothing to act on. I've retitled the PR and rewritten the description to match.

Merge summary:

  • Decision (maintainer): abandon the quest as unreproducible rather than resolved. Retitled the PR and rewrote the description; dropped the incorrect claim that refactor(mux): drive TS exports from catalog streams #5561 covered the linger decision.
  • Agreed with the Codex finding's factual point and replied to it. The real-process exit tests stay in place, so a recurrence fails loudly and gets a new quest.
  • No code changes. CI is green on be80d6d0d.
