pingqiu 10833c8b68 refactor: preserve bounded volume mode reason heartbeat truth
Carry explicit volume_mode_reason across the heartbeat/master/API seam so outward surfaces retain the bounded core-owned explanation behind mode transitions.

pingqiuandClaude Opus 4.6 8c2485e0e9 feat: Phase 15 + Phase 16A/B — V2 core integration + checkpoint review
Phase 15: V2 core wired into BlockService
- volume_server_block.go: v2Core field, applyCoreAssignmentEvent,
  core command executors (ApplyRole, StartReceiver, ConfigureShipper,
  InvalidateSession, StartCatchUp, StartRebuild, PublishProjection)
- Assignment processing now goes through core engine → command emission
  → bounded execution, replacing direct V1 replication setup
- master_block_registry.go: ClusterHealthSummary, VolumeMode in entries
- master_server_handlers_block.go: blockStatusHandler, entryToVolumeInfo
  refactored with entryReplicaSurface

Phase 16A: Core projection surfaces
Phase 16B: Bounded closure (checkpoint review ready)

Test fixes: add v2Core to manually-constructed BlockService in
idempotence, convergence, soak, and CP13-8A tests (required because
V1 replication setup paths now delegate to core engine).

All tests pass (21s regression).

pingqiuandClaude Opus 4.6 4c7fbefe25 feat: CP13-8 PASSES — real-workload validation on RF=2 sync_all
CP13-8 scenario results on m01/M02 (25Gbps RoCE):
  fsck_ext4:       CLEAN
  file count:      200 (assert_equal PASS)
  checksum match:  MATCH (assert_contains PASS)
  pgbench TPS:     565.69 (assert_greater PASS)
  auto-failover:   10.0.0.1:18480 → 10.0.0.3:18480

Code changes (tester + scenario):
- volume_server_block.go: readiness state, assignment lifecycle cleanup
- block_heartbeat_loop.go: readiness-aware heartbeat reporting
- store_blockvol.go: readiness tracking
- master_server_handlers_block.go: block API handler updates
- cp13-8-real-workload-validation.yaml: redesigned scenario
  (removed block_promote, use natural auto-failover flow,
  bootstrap write before wait_volume_healthy)
- testrunner/actions/devops.go: scenario action improvements
- replica_read_test.go: component-level replica read test

Phase docs: CP13-7 accepted, CP13-8/8A technical packs updated,
design docs updated for protocol closure evidence.

Ping QiuandClaude Opus 4.6 bb691a5458 feat: CP11B-4 observability pack — health state, alerts, dashboard
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.
