feat: Phase 20 Stage 0+1 closure — bootstrap + sustained workload on hardware
Stage 0 (bootstrap closure): PASS on m01/M02
- create RF=2 sync_all → 10s shipper wait → 4k fsync → publish_healthy
- Proves: BarrierAccepted observation, ShipperConnected, DurableLSN > 0
Stage 1 (sustained workload): 32/33 actions PASS
- bootstrap → fio 10s randwrite → dd_write 1M×2 fsync → data checksum
- Remaining: auto-failover promotion (separate issue)
Key fixes:
- BarrierAccepted callback: SyncCache success → core DurableLSN update
- BarrierRejected callback: barrier failures surface to core with reason
- Shipper state callback for new volumes (not just startup volumes)
- CatchUpTo ctrl conn reset: prevents stale control channel after recovery
- CP13-6 max-bytes budget suspended: uses replicaFlushedLSN which can't
advance without barrier; kills healthy shippers during async writes.
Will be replaced by v2 negotiated sync/recovery protocol.
- Barrier diagnostic logging: start/fail/success with reason and LSN
- Scenario restructured: Stage 0 (bootstrap-closure) + Stage 1 (failover)
- dd_write: sync_mode param + real stderr capture
- sw-test-runner suite command: deploy once, run N scenarios
- WAL size plumbing: proto + API + handler (forward-compatible)
Known: 6 blockvol/server test failures from Barrier() path change
(bounded catch-up in Barrier). Need test updates to match new semantics.

feat: Phase 20 acceptance fixes + sw-test-runner suite mode
Acceptance rows closed:
- WriteLBA/SyncCache contract: code comments document write-back vs
durability fence semantics
- RF=2 stable identity: v2bridge always uses SetReplicaAddrs (preserves
ServerID); blockcmd dispatcher also fixed to use setupPrimaryReplicationMulti;
test asserts exact expected ReplicaID="vs-2" (not just non-empty)
- Tests treating WriteLBA as commit: replica_read_test rewritten with
SyncCache as durability fence
- publish_healthy contract: 3 gate tests with hard assertions including
gate 3 (PrimaryShipperConnected)
- SetReplicaAddr deprecation warning added
- WALShipper.ReplicaID() getter added for identity verification
Test runner enhancements:
- sw-test-runner suite command: build → deploy → run N scenarios in one
invocation with --skip-deploy support
- Suite YAML definitions for T6 Stage 0 and Stage 1
- deploy action: kill stale processes, clean dirs, cross-compile, upload
- run-phase20-t6.ps1 PowerShell script (deprecated by suite command)
Engine/runtime fixes:
- Recovery executor nil-safety improvements
- Recovery bundle BuildRecoveryBundle defensive checks
- ShipperGroup MinReplicaFlushedLSNAll surface
Docs: acceptance checklist refined, test matrix updated, T6 runbook,
engine maintainer tutorial, design README updated.

feat: CP8-3-1 durability modes + testrunner platform + 21 adversarial tests
Durability mode implementation (sync_all, sync_quorum, best_effort):
- DurabilityMode type with superblock persistence, parse/validate/string
- MakeDistributedSync mode-aware barrier enforcement in dist_group_commit
- blockerr sentinel package (ErrDurabilityBarrierFailed, ErrDurabilityQuorumLost)
- gRPC create path: mode validation, idempotent create consistency, partial cleanup
- F1: strict mode rejects partial replica provisioning with cleanup
- F3: empty heartbeat does not overwrite persisted strict mode
- F4: SCSI error mapping uses errors.Is sentinels (not string matching)
- Proto/wire/blockapi/CLI/UI plumbing for durability_mode field
- Observability dashboard: cluster health cards + per-volume columns
Testrunner platform (YAML-driven integration test framework):
- Engine, parser, registry, reporter (JUnit XML + HTML), metrics scraping
- 52 registered actions: block, iSCSI, I/O, fault injection, assertions
- Baseline regression framework with 7 hard-fail conditions
- 15 YAML scenarios (smoke, crash, HA, fault, consistency, snapshot)
- 49 unit tests for testrunner internals
QA adversarial suite (21 tests, all PASS):
- Idempotent create mode/RF mismatch detection
- Heartbeat mode downgrade prevention (F3)
- sync_all/sync_quorum partial replica enforcement (F1)
- Concurrent create race safety
- Failover/expand mode preservation
- Cleanup resilience when delete fails
- Master restart auto-register mode handling
- Superblock roundtrip all 3 modes
- Validate edge cases (mode×RF matrix)
- RequiredReplicas quorum math verification
- Sentinel error categorization
