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.

pingqiuandClaude Opus 4.6 46ef79ce35 fix: stable ServerID in assignments, fail-closed on missing identity, wire into ProcessAssignments 
Finding 1: Identity no longer address-derived
- ReplicaAddr.ServerID field added (stable server identity from registry)
- BlockVolumeAssignment.ReplicaServerID field added (scalar RF=2 path)
- ControlBridge uses ServerID, NOT address, for ReplicaID
- Missing ServerID → replica skipped (fail closed), logged

Finding 2: Wired into real ProcessAssignments
- BlockService.v2Bridge field initialized in StartBlockService
- ProcessAssignments converts each assignment via v2Bridge.ConvertAssignment
  BEFORE existing V1 processing (parallel, not replacing yet)
- Logged at glog V(1)

Finding 3: Fail-closed on missing identity
- Empty ServerID in ReplicaAddrs → replica skipped with log
- Empty ReplicaServerID in scalar path → no replica created
- Test: MissingServerID_FailsClosed verifies both paths

7 tests: StableServerID, AddressChange_IdentityPreserved,
MultiReplica_StableServerIDs, MissingServerID_FailsClosed,
EpochFencing_IntegratedPath, RebuildAssignment, ReplicaAssignment
