Creates sw-block/bridge/blockvol/ — concrete adapters connecting the V2 engine to real blockvol storage and control-plane state. control_adapter.go: - MakeReplicaID: volume-name/server-id (NOT address-derived) - ToAssignmentIntent: maps master assignment → engine intent - Role → SessionKind translation (pure mapping, no policy) storage_adapter.go: - BlockVolState: maps to real blockvol fields (WAL head/tail, committed, checkpoint) — NOT reconstructed from metadata - GetRetainedHistory from real state - PinSnapshot rejects untrusted checkpoint - PinWALRetention rejects recycled range - PinFullBase / ReleaseFullBase 8 bridge tests: - StableIdentity: ReplicaID = vol/server (not address) - AddressChangePreservesIdentity: same ID, different address - RebuildRoleMapping: "rebuilding" → SessionRebuild - PrimaryNoRecovery: no recovery targets for primary - RetainedHistoryFromRealState: all fields from BlockVolState - WALPinRejectsRecycled: tail validation - SnapshotPinRejectsInvalid: trust validation - E2E_AssignmentToRecovery: master assignment → adapter → engine intent → plan → execute → InSync Adapter replacement order: P0: control_adapter + storage_adapter (this delivery) P1: executor_bridge + observe_adapter (deferred) Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

// Package blockvol bridges the V2 engine to real blockvol storage and
|
|
// control-plane state.
|
|
//
|
|
// This package implements the adapter interfaces defined in
|
|
// sw-block/engine/replication/ using real blockvol internals as the
|
|
// source of truth.
|
|
//
|
|
// Hard rules (Phase 07):
|
|
// - ReplicaID = <volume-name>/<replica-server-id> (not address-derived)
|
|
// - blockvol executes recovery I/O but does NOT own recovery policy
|
|
// - Engine decides zero-gap vs catch-up vs rebuild
|
|
// - Bridge translates engine decisions into blockvol actions
|
|
//
|
|
// Adapter replacement order:
|
|
// P0: control_adapter (assignment → engine intent)
|
|
// P0: storage_adapter (blockvol state → RetainedHistory)
|
|
// P1: executor_bridge (engine executor → blockvol I/O)
|
|
// P1: observe_adapter (engine status → service diagnostics)
