CP8-1: HTTP REST API (create/delete/lookup/list/assign/servers), blockapi Go client with multi-master failover, 5 shell commands, HTML dashboard at /block/. CP8-2: RF=2/RF=3 multi-replica support -- ShipperGroup fan-out, distributed sync, health scoring, segment-based scrub, gated promotion (heartbeat freshness + WAL LSN + role checks), failover/rebuild for N>2 replicas. CP8-3: CSI snapshot + expansion -- CreateSnapshot/DeleteSnapshot/ListSnapshots RPCs, NodeExpandVolume with iSCSI rescan, snapshot ID helpers, 20 adversarial tests covering concurrent ops, edge cases, and error injection. CP8-4: Observability -- EngineMetrics atomic counters for flusher/group-commit/ WAL-shipper/scrub, 10 new Prometheus metrics, barrier_lag_lsn SLO gauge, failover/promotion/rebuild counters, request ID correlation in master gRPC logs, baseline regression framework with 7 hard-fail conditions. Total: 63 files, ~11.2K LOC, 160+ new tests. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
