feat: rebuild MVP — dual-lane session with bitmap protection
Rebuild session protocol implementation for v2-rebuild-mvp-session-protocol.md.
New files:
- rebuild_bitmap.go: RebuildBitmap — session-scoped dense bitset for
WAL-applied LBA tracking. MarkApplied on local WAL write (not receive).
ShouldApplyBase returns false for WAL-covered LBAs (WAL always wins).
- rebuild_session.go: RebuildSession — replica-side two-line rebuild.
WAL lane (ApplyWALEntry) + base lane (ApplyBaseBlock) with bitmap
conflict resolution. TryComplete requires BOTH base_complete AND
wal_applied_lsn >= target_lsn. Volume-level control surface:
StartRebuildSession, ApplyRebuildSessionWALEntry/BaseBlock,
MarkRebuildSessionBaseComplete, TryCompleteRebuildSession,
CancelRebuildSession, ActiveRebuildSession.
- rebuild_mvp_test.go: 4 correctness tests — base+WAL converge,
WAL-applied never overwritten by base, bitmap set on applied not
received, control surface start/supersede/complete.
- rebuild_transport_test.go: 2 transport-level tests — two-line with
real WAL shipping, live writes during base copy with bitmap conflict.
Design docs:
- v2-rebuild-mvp-session-protocol.md: MVP spec with message set, apply
rules, completion/failure/crash rules, test matrix
- v2-sync-recovery-protocol.md: full protocol context (keepup/catchup/
rebuild unified design, primary decision logic, two-line model)
- v2-session-protocol-shape.md: protocol shape overview
Protocol engine (reference, not production):
- sw-block/protocol/: 7-event engine with ~300 lines, 13 tests
6 rebuild tests pass, all existing component tests pass.

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.
