M1 milestone: failover evidence crosses transport/session seam. Adapter seam (failover_adapter.go): - FailoverEvidenceAdapter: query-side (promotion evidence + replica summary) - FailoverTakeoverAdapter: execution-side (prepare + gate) - FailoverTarget: binds NodeID + both adapters - NewInProcessFailoverTarget: factory for in-process case Transport seam (failover_evidence_transport.go): - FailoverEvidenceTransport: request/response interface with nodeID routing - FailoverEvidenceHandler: server-side registration - InMemoryFailoverEvidenceTransport: first transport impl (in-memory) - NewHybridInProcessFailoverTarget: transport-backed evidence + local takeover Runtime manager (runtime_manager.go): - InProcessRuntimeManager: participant registry + ExecuteFailover entry point - Persisted failover snapshots/results per-volume and global-last All failover paths (session/driver/manager) now go through adapter seam. Old FailoverParticipant preserved as compatibility wrapper only. Phase 18 docs: phase-18.md (M1-M5 structure), log, decisions. Design docs updated: kernel-closure-review, claim-and-evidence ledger.
