| `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`. |
| `ReplicationFileMeta` | Replication status, decisions, MRF entries, resync decisions, and target reset helpers. | `rustfs_filemeta` replication contracts are concentrated in `replication_filemeta_boundary.rs`; `FileInfo` remains in the storage boundary for storage trait bindings and walk options. |
| `ReplicationQueueContracts` | Queue admission, heal queue results/actions, worker operations, worker sizing, and backpressure decisions. | Owned by `crates/replication`; ECStore imports them through `replication_queue_boundary.rs`. |

| `ReplicationTargetStore` | Bucket target listing, target client lookup, target offline checks, target config types, target operation option types, and target HeadObject comparison adapters. | Bucket target sys access, `BucketTargets`, target operation types, and HeadObject-to-replication DTO adapters are exposed through the contract type in `replication_target_boundary.rs`. |
| `ReplicationRuntime` | Worker pool, queue sizing, stats, bucket monitor, local node identity, cancellation, and admission state. | Direct runtime source/global access and shared replication pool/stat state; ECStore object store and bucket monitor implementation types stay behind local storage/bandwidth boundaries. |
