DeleteRestoredAction is supposed to demote a restored object back to its pure transitioned state: remove only the local restored copy, strip the x-amz-restore headers, and leave the version (and the remote tier data) untouched. expire_transitioned_object set opts.transition.expire_restored accordingly, but no delete path ever read the flag, so delete_object ran an ordinary delete: on unversioned buckets the whole object vanished and the free-version record scheduled remote tier cleanup (tier data loss); on versioned buckets the latest version got a spurious delete marker that replication propagated. Route expire_restored explicitly in SetDisks::delete_object before delete-marker resolution and replication dispatch: target the found version with FileInfo.expire_restored=true and return early. The FileMeta::delete_version layer already implements the semantics (strip restore headers, keep the version, hand back the local data dir); this wires it up. Also fix the action matching in expire_transitioned_object (extracted into transitioned_object_delete_opts): DeleteRestoredVersionAction previously fell through to the full transitioned-object delete, which removed the remote tier data of a noncurrent restored version. It now routes through the same restored-copy cleanup with the exact version id, matching MinIO's Action.DeleteVersioned()/DeleteRestored() dispatch. Re-enable test_restore_chain_local_read_expiry_keeps_remote_and_allows_ re_restore in the ILM Integration (serial) lane; add unit tests pinning the event->options routing and the filemeta expire_restored branch. Closes rustfs/backlog#1302
RustFS Scanner
RustFS Scanner is the background maintenance scan loop. It handles usage accounting, lifecycle expiry and transition admission, bucket replication repair admission, scanner-driven heal/bitrot checks, and namespace alerts.
For operator-facing runtime controls, status fields, and tuning workflows, see Scanner Runtime Controls. For repeatable scanner-pressure validation, see Scanner Benchmark Runbook.
Chinese documentation is available in README.zh-CN.md.
