 - PR type for this branch: `pure-move`
 - Runtime behavior changes: none.
-- Rust code changes: move admin handler/service/router, app usecase/context,
-  and storage RPC/S3 API ECStore compatibility consumers behind owner-local
-  compatibility boundaries.
-- CI/script changes: guard against restoring direct owner compatibility
-  consumers outside local compatibility boundary modules.
-- Docs changes: record the API-101 owner compatibility consumer cleanup.
+- Rust code changes: move storage core ECStore compatibility consumers behind
+  the `core_storage_compat` boundary.
+- CI/script changes: extend owner compatibility consumer guard coverage across
+  `rustfs/src/storage`.
+- Docs changes: record the API-102 storage core compatibility consumer cleanup.
