feat: Phase 8 CP8-1/2/3/4 -- ops control plane, multi-replica, CSI snapshots, observability
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.
