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
Closesrustfs/backlog#1923
Agent-instruction and architecture docs had drifted from the code:
- CLAUDE.md: slim to commands + pointers; fix wrong claim that
`make pre-commit` is the full pre-PR gate (that is `make pre-pr`);
drop stale pre-#3929 file paths and merged bug narratives
- AGENTS.md: drop dead `rust-refactor-helper` skill rule and the
hand-maintained (already stale) scoped-AGENTS index; link
architecture docs from Sources of Truth
- .github/AGENTS.md: replace the outdated copied CI command matrix
with a pointer to ci.yml
- crates/AGENTS.md: merge duplicated Testing sections
- ARCHITECTURE.md: resolve the utils->config contradiction (edges are
removed), mark volatile counts as snapshots, fix a bad path
- docs/architecture: add README router; move one-shot plans/trackers
(rebalance-decommission phases, migration-progress ledger, PR
template) to docs/superpowers/plans with archive headers; fix stale
source paths in kept inventories (core/sets.rs, core/pools.rs,
store/mod.rs, startup_* split from #3671)
- docs/operations/tier-ilm-debugging.md: extracted tier debugging
playbook with corrected paths
- scripts/check_doc_paths.sh: new guard failing pre-commit/pre-pr when
instruction/architecture docs reference nonexistent file paths
- .claude/skills: add tier-debug and arch-checks repo skills;
.gitignore now keeps .claude/skills and docs/operations committable
Verification: ./scripts/check_doc_paths.sh,
./scripts/check_architecture_migration_rules.sh (both pass)
