feat: Phase 6 CP6-3 -- failover + rebuild in Kubernetes, 126 tests
...
Wire low-level fencing primitives to master/VS control plane and CSI:
- Proto: replica/rebuild address fields on assignment/info/response messages
- Assignment queue: retain-until-confirmed (Peek+Confirm), stale epoch pruning
- VS assignment receiver: processes assignments from HeartbeatResponse
- BlockService replication: ProcessAssignments, deterministic ports (FNV hash)
- Registry replica tracking: SetReplica/ClearReplica/SwapPrimaryReplica
- CreateBlockVolume: primary + replica, enqueues assignments, single-copy mode
- Failover: lease-aware promotion, deferred timers with cancellation on reconnect
- ControllerPublish: returns fresh primary iSCSI address after failover
- Recovery: recoverBlockVolumes drains pendingRebuilds, enqueues Rebuilding
- Real integration tests on M02: failover address switch, rebuild data
consistency, full lifecycle failover+rebuild (3 tests, all PASS)
Review fixes (12 findings, 5 High, 5 Medium, 2 Low):
- R1-1: AllocateBlockVolume returns replication ports
- R1-2: setupPrimaryReplication starts rebuild server
- R1-3: VS sends periodic block heartbeat for assignment confirmation
- R2-F1: LastLeaseGrant set before Register (no stale-lease race)
- R2-F2: Deferred promotion timers cancelled on VS reconnect
- R2-F3: SwapPrimaryReplica uses RoleToWire instead of uint32(1)
- R2-F4: DeleteBlockVolume deletes replica (best-effort)
- R2-F5: SwapPrimaryReplica computes epoch atomically under lock
- QA: SetReplica removes old replica from byServer index (BUG-QA-CP63-1)
126 CP6-3 tests (67 dev + 48 QA + 8 integration + 3 real).
Cumulative Phase 6: 352 tests. All PASS.

feat: Phase 4A CP4a -- simulated master, assignment sequence tests, BlockVolumeStatus
...
Add SimulatedMaster test helper + 20 assignment sequence tests (8 sequence,
5 failover, 5 adversarial, 2 status). Add BlockVolumeStatus struct and
Status() method. Includes QA test files for CP1-CP4a. 940 total unit tests.

feat: Phase 4A CP1 — epoch, lease, role state machine, write gate
...
Local fencing primitives for block volumes. Every write path validates
role + epoch + lease before accepting data. RoleNone (default) skips
all checks for Phase 3 backward compatibility.
New files: epoch.go, lease.go, role.go, write_gate.go
Modified: superblock.go (Epoch field), blockvol.go (fencing fields,
writeGate in WriteLBA/Trim), group_commit.go (PostSyncCheck/Gotcha A),
dirty_map.go (P3-BUG-9 power-of-2 panic)
Bug fixes: BUG-4A-1 (atomic epoch), BUG-4A-2 (CAS SetRole),
BUG-4A-3 (mutex SetEpoch), BUG-4A-4 (single role.Load),
BUG-4A-6 (safeCallback recover)
837 tests (557 engine + 280 iSCSI), all passing.
