Two windows let one Codex credential refresh delete another live refresh lock. isRefreshLockStale treated any unreadable lock as stale. The owner creates the file with openSync(path, "wx") and writes its metadata immediately after, so a live lock is briefly empty; a waiter that looked during that window deleted the lock and ran a second concurrent refresh against the same grant. The unreadable case now ages the file itself and only reports stale past the same 60s window, and a lock that has already disappeared reports not stale so the waiter simply retries the create. The release path unlinked by name. If a waiter had reclaimed the path and a second owner recreated it, the first owner deleted the second owner's live lock on its way out. Release now compares the fd identity captured before close against the current path and unlinks only its own file, falling back to the previous behavior when the identity cannot be read. Both cases are pinned in tests/codex-integration/codex-account-store.test.ts and both fail before this change.

Keep the refresh-lock descriptor open through serialized identity checking and conditional unlink. Failed or unknown ownership probes preserve the callback result and retain the lock for stale recovery. Asynchronous refresh work stays outside the metadata transaction.
