* refactor(replication): move resyncer pure decision logic into rustfs-replication (M2) Pure-move milestone M2 of the ECStore replication split (backlog#1675 P1-17): relocate the resyncer's IO-free decision helpers, with their unit tests, into the crates they already belong to by type ownership. No behavior change. Moved into crates/replication: - resync.rs: resync_status_duration - delete.rs: resync_existing_delete_replication_info, replicate_delete_outcome, target_delete_version_id, delete_marker_purge_version_id, delete_marker_purge_mrf_entry - object.rs: version_identity_drifted, is_replication_target_offline_error, SsecPassthroughCapability, SsecPassthroughGate, ssec_passthrough_gate, ssec_passthrough_evidence_present (param-demoted to the echoed customer-algorithm string; ECStore keeps the HeadObjectOutput adapter) - filemeta.rs: NULL_VERSION_ID wire literal (crate-owned copy per the filemeta-independence contract) ECStore rewiring (Rule #14: imports stay in *_boundary.rs): - resync/object-decision/target boundaries re-export the moved symbols; resyncer call sites are unchanged - bucket_target_sys keeps only the verdict cache + TTL and re-exports the capability enum so existing consumer paths keep compiling Not moved (signatures carry ECStore or aws-sdk types): verify_resync_head_result, resync_target_error_detail, the SdkError classifiers, the replicate_all_* option/info builders, and the env-coupled bounded_resync_max_jobs admission clamp. README milestone table updated. * chore(replication): retire the datatypes.rs relay early README sanctions retiring datatypes.rs ahead of M4. The module was a pure relay (resync boundary -> datatypes -> mod.rs facade) with no external consumer importing it directly, so the facade now re-exports ResyncStatusType from replication_resync_boundary and the relay file is deleted. Consumers stay behind the ECStore facade, keeping Migration Rule #15 intact — the original retirement wording ("consumers import through rustfs-replication directly") conflicted with that rule and is corrected in the README. * chore(arch): extend migration guards to the M2-moved decision contracts The adversarial review of the M2 move found the per-symbol ratchet in check_architecture_migration_rules.sh was not extended for the moved symbols, leaving them free to be redefined in ECStore or imported past their boundary without CI noticing: - resync definition pin + boundary fences gain resync_status_duration; - the object-decision boundary fences gain the five delete-family helpers (delete_marker_purge_mrf_entry, delete_marker_purge_version_id, replicate_delete_outcome, resync_existing_delete_replication_info, target_delete_version_id); - the target-boundary fence gains the SSE-C gate family, the offline classifier, and version_identity_drifted; - a new definition pin rejects ECStore redefinitions of the M2-moved fns/enums (ssec_passthrough_evidence_present deliberately excluded: ECStore keeps a thin HeadObjectOutput adapter under that name). Mutation-verified: a probe fn ssec_passthrough_gate under crates/ecstore/src/bucket/replication trips the new pin. Also anchors the intentionally-duplicated NULL_VERSION_ID wire literal from the filemeta side and tightens the M2 README note on bounded_resync_max_jobs.
