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 7c07d9c95a feat: Phase 4A CP4b-3 -- assignment processing, 2 bug fixes, 20 QA tests 
Add ProcessBlockVolumeAssignments to BlockVolumeStore and wire
AssignmentSource/AssignmentCallback into the heartbeat collector's
Run() loop. Assignments are fetched and applied each tick after
status collection.

Bug fixes:
- BUG-CP4B3-1: TOCTOU between GetBlockVolume and HandleAssignment.
  Added withVolume() helper that holds RLock across lookup+operation,
  preventing RemoveBlockVolume from closing the volume mid-assignment.
- BUG-CP4B3-2: Data race on callback fields read by Run() goroutine.
  Made StatusCallback/AssignmentSource/AssignmentCallback private,
  added cbMu mutex and SetXxx() setter methods. Lock held only for
  load/store, not during callback execution.

7 dev tests + 13 QA adversarial tests = 20 new tests.
972 total unit tests, all passing.

Ping QiuandClaude Opus 4.6 a089bf6828 feat: Phase 4A CP4b-2 -- heartbeat collector, 3 bug fixes, 9 QA tests 
BlockVolumeHeartbeatCollector periodically collects block volume status
via callback (standalone, no gRPC wiring yet). Store() accessor on
BlockService. Three bugs found by QA and fixed: Stop-before-Run deadlock
(BUG-CP4B2-1), zero interval panic (BUG-CP4B2-2), callback panic crashes
goroutine (BUG-CP4B2-3). 12 new tests (3 dev + 9 QA adversarial).
