+- [x] `API-230` Route admin usecase construction through runtime boundary.
+  - Do: expose admin usecase construction and required admin DTO types from
+    `rustfs/src/admin/runtime_sources.rs`, then route system, pool, cluster
+    snapshot, plugin catalog, table catalog, module-switch, and console admin
+    discovery paths through that boundary.
+  - Acceptance: migrated admin handler sources no longer import
+    `crate::app::admin_usecase` directly, and the server-info route guard
+    requires the admin runtime-source constructor.
+  - Must preserve: admin authentication and authorization checks, admin
+    discovery route values, storage/data-usage/pool/decommission responses,
+    cluster snapshot collection, plugin catalog payloads, table catalog config
+    payloads, module switch responses, and console config discovery.
+  - Verification: focused admin tests, formatting, migration and layer guards,
+    diff hygiene, residual admin usecase import scan, Rust risk scan, and full
+    PR gate passed before PR.
+

 ## Pre-Push Review Log
 
 | Expert | Status | Notes |
 |---|---|---|
+| Quality/architecture | pass | API-230 moves admin handler `DefaultAdminUsecase` construction behind the admin runtime-source boundary instead of letting each handler import the app usecase directly. |
+| Migration preservation | pass | Admin auth checks, discovery URLs, system info, pool/decommission, cluster snapshot, plugin catalog, table catalog, module-switch, and console responses keep the same usecase implementation. |
+| Testing/verification | pass | Focused admin tests, formatting, migration/layer guards, direct app-usecase import scan, diff hygiene, Rust risk scan, and full PR gate passed before PR. |
 | Quality/architecture | pass | CTX-002 cleanup makes OIDC resolution AppContext-owned and removes the unused IAM-to-OIDC shortcut instead of keeping a hidden global bypass. |
 | Migration preservation | pass | Startup still treats OIDC initialization as non-fatal and publishes the initialized handle when available; admin OIDC, STS, and console consumers keep the same response behavior. |
 | Testing/verification | pass | Focused app::context tests, formatting, compatibility marker scan, and Rust risk scan passed; full PR gate is planned before PR. |
