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. Refs rustfs/backlog#596 rustfs/backlog#603 rustfs/backlog#580

Architecture Documentation
Durable architecture reference for RustFS: migration guardrails, runtime contracts, boundary rules, and support matrices.
Two rules keep this directory healthy:
- Durable reference only. One-shot implementation plans, task trackers,
and PR templates live in
docs/superpowers/plans/and are archived there when their work closes. - No copies of other sources of truth. Crate lists come from
Cargo.toml, CI steps from.github/workflows/ci.yml, code structure from the code.scripts/check_doc_paths.shfails the pre-commit gate when a doc here references a file path that no longer exists.
Start here
- overview.md — migration baseline, phase order, core principles
CI-enforced core (required by scripts/check_architecture_migration_rules.sh)
- crate-boundaries.md — dependency direction, PR types, re-export contracts
- runtime-lifecycle.md — startup/shutdown sequencing, readiness guarantees
- readiness-matrix.md — request/dependency behavior, probe semantics
- storage-control-data-plane.md — storage API contracts, control-plane boundaries
- global-state-crate-split-plan.md — remaining global-state owners and split evaluation
- ecstore-module-split-plan.md — ECStore decomposition rules and facade contracts
