Health-state derivation: deriveHealthStateWithLiveness() computes per-volume state (unsafe > rebuilding > degraded > healthy) using role, replica count, durability mode, degraded flag, and primary server liveness. Used consistently in both volume responses and cluster summary. Extended GET /block/status with health counts (healthy, degraded, rebuilding, unsafe) and NVMe-capable server count. Response is now typed BlockStatusResponse instead of untyped map. Default alert pack: 7 Prometheus rules covering WAL pressure, flusher errors, replica degradation, rebuilding, scrub errors. Alert rules reference real seaweedfs_blockvol_* metric names. Default dashboard: Grafana JSON with 17 panels — cluster health, IOPS, latency P99, WAL pressure, flusher throughput, replication, scrub, dirty map, epoch. 17 tests: 9 health derivation, 1 cluster summary, 2 handler/API, 2 alert validation, 2 dashboard validation, 1 liveness parity.
