fix: Lookup/ListAll return copies, add UpdateEntry for safe mutation
...
Lookup() and ListAll() now return value copies (not pointers to
internal registry state). Callers can no longer mutate registry
entries without holding a lock.
Added clone() on BlockVolumeEntry with deep-copied Replicas slice.
Added UpdateEntry(name, func(*BlockVolumeEntry)) for locked mutation.
ListByServer() also returns copies.
Migrated 1 production mutation (ReplicaPlacement + Preset in create
handler) and ~20 test mutations to use UpdateEntry.
5 new copy-correctness tests: Lookup returns copy, Replicas slice
isolated, ListAll returns copies, UpdateEntry mutates, UpdateEntry
not-found error.

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.

feat: CP8-3-1 durability modes + testrunner platform + 21 adversarial tests
...
Durability mode implementation (sync_all, sync_quorum, best_effort):
- DurabilityMode type with superblock persistence, parse/validate/string
- MakeDistributedSync mode-aware barrier enforcement in dist_group_commit
- blockerr sentinel package (ErrDurabilityBarrierFailed, ErrDurabilityQuorumLost)
- gRPC create path: mode validation, idempotent create consistency, partial cleanup
- F1: strict mode rejects partial replica provisioning with cleanup
- F3: empty heartbeat does not overwrite persisted strict mode
- F4: SCSI error mapping uses errors.Is sentinels (not string matching)
- Proto/wire/blockapi/CLI/UI plumbing for durability_mode field
- Observability dashboard: cluster health cards + per-volume columns
Testrunner platform (YAML-driven integration test framework):
- Engine, parser, registry, reporter (JUnit XML + HTML), metrics scraping
- 52 registered actions: block, iSCSI, I/O, fault injection, assertions
- Baseline regression framework with 7 hard-fail conditions
- 15 YAML scenarios (smoke, crash, HA, fault, consistency, snapshot)
- 49 unit tests for testrunner internals
QA adversarial suite (21 tests, all PASS):
- Idempotent create mode/RF mismatch detection
- Heartbeat mode downgrade prevention (F3)
- sync_all/sync_quorum partial replica enforcement (F1)
- Concurrent create race safety
- Failover/expand mode preservation
- Cleanup resilience when delete fails
- Master restart auto-register mode handling
- Superblock roundtrip all 3 modes
- Validate edge cases (mode×RF matrix)
- RequiredReplicas quorum math verification
- Sentinel error categorization
