Parent review: accepted. The evidence is solid. The job orphaned Open: the runner-side trigger (why the smart-HTTP clone after the refused push wedged) is not root-caused. If it recurs, the lane now fails red within bounds with the process tree and container logs, and it gets its own investigation. Auto-merge is on. |

- Around line 65-66: In the spawnSync result handling, check for and throw
run.error before checking run.status so timeout errors such as ETIMEDOUT are
preserved instead of replaced by the status-based Git error.

… timeout reports ETIMEDOUT CodeRabbit on #101: a timed-out spawnSync leaves status null and the reason on error; the status check replaced it with an often-empty stderr. cli.spec already throws proc.error first; create.spec now matches.
What hung
Merge-queue run 39785255412 (PR #99 on top of 043afae), job
e2e / e2e (multi round 1 shard 2)(job id 119849702825): 32 of 33 tests printed ✓, then 35 minutes of silence until the 40-minute job cancel. Playwright's summary never printed.Forensics from the job log (not a rerun — the evidence is in the log):
prs.spec.ts:432(require_pr rejects a push-role push to main…) started and never finished; every other test completed, the last at 13:26:32.npm exec playwright test, workers, chrome-headless-shell — plus twogitand onegit-remote-httpstill alive: a synchronous git child stuck mid-operation (git clone's process tree is exactly git + git-remote-http, plus index-pack).execFileSync/spawnSyncwith notimeout, which blocks the worker's event loop. Playwright's per-test/hook timeouts are in-worker timers, so they can never fire — the silence itself proves a sync block (an async hang would have timed out loudly at the 10-minute hook/test deadline). A wedged git smart-HTTP endpoint (accepts, never answers) therefore holds the whole run open silently.Fix

Localhost git ops finish in ~1 s; the bound only ever trips on a wedge, and then it throwsETIMEDOUTnaming the command. Not a longer timeout — a bound where none existed; it never makes a test pass.apps/noite/playwright.config.ts: parent-sideglobalTimeout: 25 min(release shard 2 measured ~5 min wall; unsharded local release ~2x; trips 15 min before the 40-minute job cancel, naming the stuck test). Enforced by the parent process, so it fires even with a blocked worker.docker/e2e-local.sh: a red lane now also capturesps -efintolane-host-procs.txtin the always-uploaded report, so the next stuck command (with parentage and arguments) is in the artifact. A globalTimeout failure is a red lane, not a cancel, so the existing container-log capture runs too.changelog.d/e2e-teardown-hang.md: fragment.Fail-before proof (deterministic, local)
execFileSyncwithout timeout): blocked 12 s until externally SIGKILLed; an armed 500 ms timer never fired — the event loop freeze that defeats every Playwright timeout.
