Finding 1: ProcessAssignments now calls v2Orchestrator.ProcessAssignment
- BlockService.v2Orchestrator field (RecoveryOrchestrator)
- ProcessAssignment result logged at glog V(1)
- No more `_ = intent` — engine state actually changes
Finding 2: localServerID documented as interim
- BlockService.localServerID = listenAddr (transport-shaped)
- Field doc explicitly states: INTERIM, should be registry-assigned
- Used only for replica/rebuild local identity
3 integration tests (qa_block_v2bridge_test.go):
- CreatesEngineSender: ProcessAssignment → engine has sender + session
- EpochBump: epoch 1 → invalidate → epoch 2 → new session
- AddressChange: same ServerID, different IP → sender preserved,
endpoint updated

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

AllocateBlockVolumeResponse used bs.ListenAddr() to derive replica
addresses. When the VS binds to ":port" (no explicit IP), host
resolved to empty string, producing ":dataPort" as the replica
address. This ":port" propagated through master assignments to both
primary and replica sides.
Now canonicalizes empty/wildcard host using PreferredOutboundIP()
before constructing replication addresses. Also exported
PreferredOutboundIP for use by the server package.
This is the source fix — all downstream paths (heartbeat, API
response, assignment) inherit the canonical address.

setupReplicaReceiver now reads back canonical addresses from
the ReplicaReceiver (which applies CP13-2 canonicalization)
instead of storing raw assignment addresses in replStates.
This fixes the API-level leak where replica_data_addr showed
":port" instead of "ip:port" in /block/volumes responses,
even though the engine-level CP13-2 fix was working.
New BlockVol.ReplicaReceiverAddr() returns canonical addresses
from the running receiver. Falls back to assignment addresses
if receiver didn't report.

Two-phase prepare/commit/cancel protocol ensures all replicas expand
atomically. Standalone volumes use direct-commit (unchanged behavior).
Engine: PrepareExpand/CommitExpand/CancelExpand with on-disk
PreparedSize+ExpandEpoch in superblock, crash recovery clears stale
prepare state on open, v.mu serializes concurrent expand operations.
Proto: 3 new RPCs (PrepareExpand/CommitExpand/CancelExpandBlockVolume).
Coordinator: expandClean flag pattern — ReleaseExpandInflight only on
clean success or full cancel. Partial replica commit failure calls
MarkExpandFailed (keeps ExpandInProgress=true, suppresses heartbeat
size updates). ClearExpandFailed for manual reconciliation.
Registry: AcquireExpandInflight records PendingExpandSize+ExpandEpoch.
ExpandFailed state blocks new expands until cleared.
Tests: 15 engine + 4 VS + 10 coordinator + heartbeat suppression
regression + updated QA CP82/durability tests with prepare/commit mocks.
Also includes CP11A-1 remaining: QA storage profile tests, QA
io_backend config tests, testrunner perf-baseline scenarios and
coordinated-expand actions.

Add nvme_addr and nqn fields to proto messages (AllocateBlockVolume,
CreateBlockVolume, LookupBlockVolume, BlockVolumeInfoMessage), wire
through volume server → master registry → CSI driver. Volume servers
report NVMe address in heartbeats when NVMe target is running. CSI
MasterVolumeClient now populates NvmeAddr/NQN from master responses,
enabling NVMe/TCP via the master-backend path.
Proto files regenerated with protoc 29.5.

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).
