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 Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
