A concurrent reader briefly holding a file open made `deleteJSON` throw a share-violation `EPERM`, which surfaced as a failed operation — for example a failed `run.cancel()` while `deleteAllHooksForRun` raced hook polling.

Close is idempotent on the server (unlike chunk appends, which keep their no-5xx retry policy), and the server may return retriable 503s expecting the writer to close again.
