+- [x] `E-003/E-LAYOUT-002` Move ECStore endpoint layout owners.
+  - Do: pure-move endpoint parsing and endpoint grouping into the ECStore
+    layout bucket while keeping compatibility stubs at the old public paths.
+  - Acceptance: `crate::disk::endpoint::*` and `crate::endpoints::*` remain
+    usable, `layout::endpoint` owns `Endpoint`, and `layout::endpoints` owns
+    `EndpointServerPools` and endpoint grouping.
+  - Must preserve: endpoint string parsing, URL/path validation, local-host
+    detection, pool/set/disk indexes, endpoint grouping, disk independence
+    checks, setup type classification, and old public module paths.
+  - Verification: focused ECStore endpoint tests, ECStore/RustFS/Heal compile
+    checks, migration/layer guards, formatting, diff hygiene, Rust risk scan,
+    branch freshness check, pre-commit quality gate, and three-expert review.
