Investigation result: - Dual-BlockVol hypothesis: DISPROVEN (one instance per path, correct wiring) - Root cause: adapter wiring bug in test allocator soak_test.go blockVSAllocate returned ReplicaDataAddr = "vs2:9333:14260" (server + ":port" where server already has a port → three colons, invalid) This caused setupReplicaReceiver to fail silently → no data replicated Root cause classification: adapter/test-harness bug - NOT a backend data visibility bug - NOT a core-rule gap - The engine read path works correctly (TestSyncAll_FullRoundTrip passes) Code changes: - qa_block_soak_test.go: fix allocator to use host:port (not server:port), use deterministic FNV-hashed ports matching production ReplicationPorts - qa_block_cp13_8a_test.go: 2 new integration tests proving replica reads work through both ReadLBA and adapter.ReadAt, before and after promotion Remaining contradiction for CP13-8 scenario on real hardware: - The production weed cluster uses ReplicationPorts (deterministic) which should not have this bug. If CP13-8 still fails on m01/M02, the cause is different from this test-harness issue and needs a separate investigation. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
