-## Tier Free Versions During Decommission
-
-A tier free version is an internal xl.meta record (`rustfs_filemeta::FREE_VERSION`,
-flagged `XL_FLAG_FREE_VERSION`) shaped like a delete marker. It is created by
-`MetaObject::init_free_version` when a version whose remote transition completed is
-deleted locally: the visible version is removed and the record keeps the remote-tier
-identity (tier, object name, version id, state, destination id) needed for an
-idempotent remote delete. Free versions are not user-visible versions; `num_versions`
-and all listing/GET paths exclude them.
-
-### Lifecycle And Consumers
-
-Creation: any local delete that removes a version whose transition status is
-`complete` appends the record via `MetaObject::delete_version` →
-`init_free_version` (skipped only when `skip_tier_free_version` is set, as on
-data-movement copies). The same deletes also persist a durable tier-journal
-entry on every user-facing path: S3 single deletes (`execute_delete_object` →
-`delete_object_with_tier_delete_journal`), S3 batch deletes, lifecycle expiry,
-and lifecycle delete-all all prepare and commit a journal entry around the
-delete. A journal entry is omitted when the removed version's transition state
-decodes as `TransitionVersionState::Unknown`, or on internal journal-less
-delete paths that never touch transitioned user objects.
-
-Consumption while the record exists: the background recovery loop started by
-`init_background_expiry` (spawned by `spawn_tier_free_version_recovery_once`,
-enabled by default) scans disks for pending records and re-enqueues them; the
-usage scanner does the same; the lifecycle worker then deletes the remote tier
-object idempotently and only afterwards removes the local record. Heal walks
-include free-version records in metadata healing. Transition planning,
-replication, restore, GET, listings, and usage aggregation never depend on
-them.
-
-### Decommission Handling
-
-The exact decommission inventory loader (`load_file_info_versions_exact` via
-`get_all_file_info_versions`) keeps free-version records inline in `versions`.
-The migration loop handles them before lifecycle expiry and delete-marker
-shortcuts. It selects a target pool using the free-version-aware lookup, then
-writes the original free record to every target disk with the normal metadata
-write quorum. The free-version marker, local version id, transition identity,
-transition state, and destination id are preserved at the FileInfo/metadata
-boundary.
-
-The source record is physically removed only after the target write quorum has
-committed and the source cleanup preflight still matches the exact inventory.
-If the lifecycle worker has already completed the remote delete and removed the
-source record before decommission acquires the source lock, decommission records
-that identity as already consumed and treats the missing source record as safe.
-If target capacity, metadata validation, lock fencing, or quorum fails, the
-source record remains and the entry records `state = "free_version_retained"`
-with reason `tier_free_version_migration_failed`; the worker retries the
-operation on a later pass. A target record with the same version id is accepted
-only when its free-version identity matches; a conflicting ordinary version or
-different free record is an overwrite error. This makes retries idempotent and
-prevents a free record from replacing a user-visible version.
-
-### Reference-Audit Result
-
-After migration, user-facing GET/list/transition/replication/restore paths still
-exclude the record. Recovery, usage scanning, lifecycle tier cleanup, and heal
-continue to see it when they request free versions, so an unresolved remote
-delete remains actionable on the target pool. The committed tier journal remains
-an independent retry source where one exists; it is not used as a reason to drop
-the xl.meta record. In particular, `Unknown` transition state records are
-migrated unchanged rather than discarded: the lifecycle worker retains them if
-remote identity validation cannot make a delete request.
-
-Each migrated record emits `state = "free_version_migrated"` with reason
-`tier_free_version_migrated`. A record consumed before migration emits
-`state = "free_version_consumed"` with reason
-`tier_free_version_already_consumed`. Each failed record emits the retained state
-and failure reason above. The entry also emits a disposition summary with
-migrated, consumed, retained, and total counts. The final decommission sweep uses
-the exact loader, counts free records still present, and emits one retained
-record/reason for each unresolved free version before failing the sweep. This
-makes successful migration, completed cleanup, and retained cleanup obligations
-visible instead of silently omitting free records.
-
-No new S3-visible version or admin response field is needed: free versions remain
-internal and are never counted as user-visible versions. The structured
-`decommission_entry` events are the operational status surface for the
-free-version disposition; the existing decommission item/failed counters still
-report the enclosing object migration result.
