+- [x] `API-206` Centralize root, app, and storage RPC runtime source readers.
+  - Do: route root auth/init/config/protocol/workload consumers, app usecase
+    consumers, and storage node-service runtime resolver consumers through
+    root, app, or storage runtime-source boundaries.
+  - Acceptance: migrated root/app/storage consumers no longer import AppContext
+    resolvers directly, and migration rules reject reintroducing those direct
+    resolver reads outside the owner runtime-source modules.
+  - Must preserve: request credential lookup, IAM readiness checks, update and
+    notification startup behavior, runtime region and buffer config lookup,
+    workload admission replication status, S3 Select DB lookup, app-context
+    object-store/notification resolution, and node-service IAM/lock behavior.
+  - Verification: focused RustFS compile/tests, formatting, migration and layer

+    PR gate, and full PR gate before PR.
