Add computed VolumeMode to BlockVolumeEntry with 5 normalized modes:
- allocated_only: RF=1, no replicas (standalone)
- bootstrap_pending: RF>1 but replicas not yet ready (first-write pending)
- publish_healthy: all replicas ready, no transport degradation
- degraded: replication impaired but recoverable
- needs_rebuild: unrecoverable gap, rebuild required
Code changes:
- master_block_registry.go: computeVolumeMode() called from
recomputeReplicaState(), VolumeMode field on BlockVolumeEntry
- master_server_handlers_block.go: VolumeMode exposed in REST API
- blockapi/types.go: VolumeMode field in VolumeInfo
- testrunner types: VolumeMode for scenario assertions
7 tests prove mode normalization:
- AllocatedOnly, BootstrapPending (2 cases), PublishHealthy,
Degraded, NeedsRebuild, SurfaceConsistency (transition proof)
Interpretation rule: current integrated tests validate V1 runtime
under V2 constraints, not a completed V2 runtime (Phase 14 scope).
