 |---|---|---|---|
 | `APP_CONTEXT_SINGLETON` | `rustfs/src/app/context/global.rs` | Owner-local compatibility | Keep as the context-first facade while no-context startup and embedded callers still exist. |
 | `GLOBAL_OBJECT_API`, `GLOBAL_OBJECT_STORE_RESOLVER` | `crates/ecstore/src/runtime/global.rs` | Runtime migration target | Do not migrate first; it is tied to storage startup, IAM-after-storage AppContext publication, and data-plane resolver compatibility. |
-| `GLOBAL_Endpoints`, `GLOBAL_IsErasure`, `GLOBAL_IsDistErasure`, `GLOBAL_IsErasureSD`, `GLOBAL_RootDiskThreshold` | `crates/ecstore/src/runtime/global.rs` and `crates/ecstore/src/runtime/sources.rs` | Runtime migration target | Move only after endpoint, setup-type, and root-disk-threshold ownership can be tested without changing readiness or quorum behavior. |

 | `GLOBAL_ExpiryState`, `GLOBAL_TransitionState`, `GLOBAL_LifecycleSys` | `crates/ecstore/src/bucket/lifecycle/*` and `crates/ecstore/src/runtime/sources.rs` | Runtime migration target | First code-bearing candidate is `GLOBAL_ExpiryState`, because AppContext already has an `ExpiryStateInterface`, resolver, and tests. |
 | `GLOBAL_REPLICATION_POOL`, `GLOBAL_REPLICATION_STATS`, `GLOBAL_BUCKET_MONITOR` | `crates/ecstore/src/bucket/replication/*`, `crates/ecstore/src/runtime/global.rs` | Runtime migration target | Keep behind AppContext replication and bucket-monitor resolvers until queue admission, stats, and admin reporting coverage are explicit. |
