Stamping an Expiration.Days rule as a volume TTL at write time bakes an irreversible TTL into the object: removing or lengthening the rule later can't un-expire it, unlike worker-driven expiration. The metadata-only delete it enables also skips per-chunk DeleteFile, so dead bytes linger in a not-yet-expired TTL volume with no deleted-byte accounting until the whole volume ages out. Gate the resolver on a per-bucket flag, off by default; toggle with the s3.bucket.lifecycle.fastpath shell command. Default writes take the worker path: real deletes that honor current policy and let vacuum reclaim space.
