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).

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.

feat: Phase 09 — V2 execution primitives and production closure
...
Engine execution layer for V2 replication protocol:
- RebuildInstaller: full state handoff (dirty map, WAL, superblock, flusher)
- TruncateToLSN: exact safety predicate (checkpointLSN == truncateLSN),
ErrTruncationUnsafe escalation to NeedsRebuild
- SyncReceiverProgress: unconditional Store for post-rebuild alignment
- V2StatusSnapshot: CommittedLSN = nextLSN-1 for sync_all
V2 bridge real I/O executors:
- TransferFullBase: TCP streaming + RebuildInstaller + second catch-up
- TransferSnapshot: SHA-256 verified streaming to disk
- TruncateWAL: ErrTruncationUnsafe detection + escalation
- StreamWALEntries: rebuild-mode TCP apply
Engine executor interfaces:
- CatchUpIO.TruncateWAL, RebuildIO.TransferFullBase returns achievedLSN
- CatchUpExecutor truncation-only skip, NeedsRebuild escalation
- RebuildExecutor uses achievedLSN for progress tracking
Design docs reorganized: superseded planning docs removed, protocol
truths and closure map added.

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
