| `ReplicationResyncContracts` | Resync options, target status, bucket status, status classifiers, and persisted resync/MRF status wire format. | Owned by `crates/replication`; ECStore imports them through `replication_resync_boundary.rs`, which maps crate errors to ECStore errors. |
| `ReplicationConfigStore` | Replication config persistence and config-derived labels used by target options. | Config read/save helpers and storage class labels are exposed through the contract type in `replication_config_store.rs`. |

10. Keep ECStore owner modules outside `bucket/replication` behind bridge
contracts when they need replication codec or config helper behavior.
11. Keep storage-api replication status/state helpers behind
`crates/storage-api/src/replication.rs` until the underlying wire contracts
can move without a `rustfs-replication` / `rustfs-storage-api` dependency
cycle.
