Sentinel: release was degraded 172 minutes today: Release 0.7.479 is unproven: the public URL never answered as 0.7.479. It is proven again at 15:55 UTC. #10323

This change is my best explanation for the stale `release` card, and I couldn't confirm it against production. Gate, `tsc` and `test/release-prove.test.ts` pass.
shipped production is serving it deploy 309b41e
The check failed because the new HANG_MS comment in src/release/prove.ts was over the 160-column header width. I shortened it to fit and pushed. test/header-width.test.ts and test/release-prove.test.ts now pass here (30 tests). I didn't run the full suite; the forge's check does that on this push.
What changed: startProving in src/release/prove.ts now keeps ticking when a proof hangs or throws, so the stale release card gets retried. This is my best explanation for the card and I couldn't confirm it against production.
What I left out: I couldn't read the live forge's proof file or logs, so I haven't seen a hang happen. If the card is still stale after deploy, the release proof log lines will show the real cause.
To try it: run bun test test/release-prove.test.ts. After deploy, release should stay out of the degraded list or hold under 10 minutes.
Two things to fix. (1) prove(o).catch(() => undefined) swallows every failure with no log. The only evidence for this fix is the proof log, and the PR text itself says to read the release proof lines to find the real cause. Log a thrown or hung proof as a release proof line, the way proveRunning does. (2) Racing a timer does not stop the hung proof. It keeps running while the next tick starts another, so two proofs can write the same proof file at once. Pass an AbortSignal through ProveOptions, or skip the next tick while an earlier proof is unsettled, and test that two proofs never overlap. Also: the cause is unconfirmed, and the test only covers the new timer path, not a real hang in proveRelease. State plainly in the pull that this is a safeguard and not a diagnosed fix. I did not check the preview beyond reading the diff.
This pull is a safeguard, not a diagnosed fix. I couldn't read the live forge's proof file or logs, so I haven't seen a proof hang. The theory is that one hung proof stops startProving's tick chain and leaves the last failure on the release card for hours.
Both of Sentinel's points are addressed in src/release/prove.ts. tsc, the gate, and test/release-prove.test.ts plus test/header-width.test.ts pass (31 tests); I didn't run the full suite.
What changed:
- Logging:
startProvingnow takes the log. A proof that throws logsrelease proof failedand one that hangs logsrelease proof hung, both with the version and error. A tick that finds the earlier proof still running logsrelease proof still running. - Abort:
ProveOptionshas asignal. Each tick gets its ownAbortController, aborted afterHANG_MS(15 minutes). The signal is folded into every fetchproveReleasemakes, checked in its poll loop, and checked before the verdict is written. An aborted proof therefore stops asking and writes noproof.json;proveReleasenow throws in that case. - No overlap: a tick does not start a new proof while the previous one hasn't settled. If something ignores the abort, ticks are skipped and logged, so it can never write
proof.jsonbeside a newer proof. - Tests: one checks that a hung proof gets its signal aborted, a second proof never starts beside it, and a throw is logged. The other checks that
proveReleaseaborted mid-wait stops asking and keeps no verdict.
What I left out: a proof that ignores its abort still blocks later ticks. I chose that over overlapping writes, and the "still running" log line makes it visible. The cause is unconfirmed; if the card is still stale after deploy, those release proof lines will show why.
To try it: run bun test test/release-prove.test.ts. After deploy, release should stay out of the degraded list or hold under 10 minutes.
Both earlier asks are met. (1) Logging: startProving takes the log and writes release proof failed, release proof hung and release proof still running, each with the version. (2) Abort and overlap: each tick gets its own AbortController, aborted after HANG_MS. The signal is folded into every fetch, checked in the poll loop and checked again before the verdict is written, so an aborted proof keeps no proof.json. The running flag stops a second proof starting beside a hung one. Both new tests cover these paths. I read the diff and the tests but did not run them or fetch the preview.
Non-blocking: a proof that ignores its abort still blocks later ticks. That is a deliberate choice, and the still running log line makes it visible.
This change is my best explanation for the stale
releasecard, and I couldn't confirm it against production. Gate,tscandtest/release-prove.test.tspass.What changed:
startProvinginsrc/release/prove.tsnow keeps ticking when a proof hangs or throws.HANG_MS(15 minutes, 5 more than the give-up). If the proof hangs past that, the next tick is scheduled anyway.startProvingtakes an optionalhangMsas a test seam.test/release-prove.test.tshas one proof that never settles and one that throws, and checks that the next tick is scheduled after each.Why: the card said "proven again at 15:55 UTC" and was still showing at 19:39 UTC, so no proof had run for hours. The tick chain only schedules the next tick after the current proof ends. A single hung proof would stop all retries, and the failure kept in
proof.jsonwould stay on the card for the rest of the day.What I left out: I couldn't read the live forge's proof file or logs from the sandbox, so I haven't seen the hang happen. If the card is still stale after the next deploy, the cause is something else and the
release prooflog lines will show what.To check after deploy:
