+- Stacked on: `overtrue/arch-disk-rpc-method-wrappers` pending API-097 merge.
 - PR type for this branch: `pure-move`
 - Runtime behavior changes: none.
-- Rust code changes: move remaining disk RPC, peer S3 RPC, heal/scanner disk,
-  and warm-backend test method access behind local compatibility traits or
-  aliases.
-- CI/script changes: remove the final direct ECStore method-resolution import
-  exceptions outside compatibility boundaries.
-- Docs changes: record the API-097 disk/RPC/warm-backend wrapper cleanup.
+- Rust code changes: move capacity, server, startup, table catalog,
+  runtime-capability, workload-admission, error, and config-test ECStore
+  compatibility consumers from the root runtime facade into local boundaries.
+- CI/script changes: guard against restoring consumer wrappers in the root
+  runtime compatibility facade and tolerate retiring the empty root facade.
+- Docs changes: record the API-098/API-099/API-100 runtime consumer boundary cleanup.

+    compatibility boundaries.
+  - Acceptance: root runtime `storage_compat.rs` no longer owns

+    migration rules reject restoring those wrappers to the root facade.
+  - Must preserve: capacity background refresh disk discovery, internode RPC
+    signature verification, live event dispatch, module-switch persistence,
+    storage readiness, and distributed lock quorum behavior.

+    boundary.
+  - Acceptance: startup and init modules no longer consume root
+    `storage_compat.rs`; root runtime `storage_compat.rs` no longer owns
+    startup-only ECStore wrapper functions or aliases; migration rules reject
+    restoring those wrappers to the root facade.
+  - Must preserve: endpoint parsing, unsupported filesystem policy,
+    local-disk and lock-client initialization, global config migration,
+    bucket metadata migration, IAM migration, notification registration,
+    default-region fallback, background replication, and shutdown behavior.
+  - Verification: RustFS test-target compile coverage, startup residual scan,
+    migration and layer guards, formatting, diff hygiene, Rust risk scan,
+    pre-commit quality gate, and three-expert review.
+- [x] `API-100` Retire root runtime storage compatibility consumers.
+  - Completed slice: move table catalog metadata constants and bucket metadata
+    reads, runtime topology capability mapping, workload admission runtime
+    state probes, S3 error mapping aliases, and config test disk-layout aliases
+    into local compatibility boundaries, then remove the root
+    `storage_compat.rs` module.
+  - Acceptance: no RustFS source consumes `crate::storage_compat`; root
+    runtime compatibility file is removed; migration rules still reject direct
+    ECStore imports outside `*storage_compat.rs` boundaries.
+  - Must preserve: table catalog internal metadata paths, lock timeout lookup,
+    runtime topology snapshots, workload admission status reporting, quota and
+    storage error mapping, and config disk-layout parsing tests.
+  - Verification: RustFS test-target compile coverage, direct root compatibility
