Add two durable architecture references grounded in current code:
- minio-rustfs-router-compatibility.md: MinIO cmd/api-router.go (S3
object/bucket) and cmd/admin-router.go (admin /v3, /v4) vs RustFS
implementation status, with per-row landing points and a gaps-only
checklist of still-missing admin endpoints (profiling, healthinfo,
LDAP IDP config, replication diff, MRF, batch, locks, speedtest,
log stream, top, trace).
- minio-file-format-compat.md: xl.meta (meta_ver 3 write, <=3 read,
XL2 magic, rs-vandermonde, HighwayHash256 bitrot, inline data) and
.metadata.bin bucket-metadata interop matrix for the backlog#580
items, plus old-RustFS -> new migration and a phased plan.
Cross-links s3-compatibility-matrix.md and admin-route-action-snapshot.md
and indexes both docs in docs/architecture/README.md.

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- .github/AGENTS.md: replace the outdated copied CI command matrix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)
