 - PR type for this branch: `pure-move`
 - Runtime behavior changes: none.
-- 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.
+- Rust code changes: narrow selected local compatibility boundaries from glob
+  re-exports to explicit re-exports.
+- CI/script changes: guard narrowed local compatibility boundaries against
+  restoring glob re-exports.
+- Docs changes: record the API-103 local compatibility export cleanup.
