Tier free versions (xl.meta cleanup records for deleted transitioned versions) are not migrated as free versions during decommission: the exact inventory keeps them inline in versions and the migration loop routes them through the generic delete-marker path, dropping the flag and remote-tier identity. Reference audit across GET, heal, ILM, transition, replication, and restore found no cluster-local consumer that resolves a free version after decommission; on user-facing delete paths the remote-delete obligation is also carried by a committed tier-journal entry, leaving only journal-less records (transition state unknown) exposed to remote orphaning. - count and log skipped free versions per decommission entry with disposition reason tier_free_version_not_migrated instead of omitting them silently - document free-version lifecycle, non-migration invariant, allowed physical-delete timing, and the reference-audit result in docs/architecture/decommission-compatibility.md - state the invariant in doc comments at the filemeta free-version sites - guard the accounting with decommission_free_version_accounting_reports_skipped_records Closes rustfs/backlog#1923
