pingqiu fb0da91196 feat: start Phase 14 V2 core shell 
Make the first V2 core owner explicit in sw-block by freezing Phase 14 docs, mode/readiness/publication semantics, and bounded command emission rules. This turns accepted Phase 13 constraints into executable core behavior without overclaiming live runtime cutover.

pingqiuandClaude Opus 4.6 21ccf06ef3 docs: Phase 13 CP13-1..CP13-7 technical packs, acceptance status, design updates 
- phase-13.md: CP13-1 through CP13-6 accepted, CP13-7 active
- phase-13-log.md: full technical + delivery packs for CP13-2..CP13-7
- phase-13-cp4-state-eligibility.md: refined barrier behavior table
  (Disconnected/Degraded as recovery entry points, not eligibility)
- phase-12.md: minor cross-reference updates
- Older phase docs: minor wording alignment
- Design docs: V2 development plan and completion overview updated

pingqiuandClaude Opus 4.6 c7eb87c587 feat: Phase 09 — V2 execution primitives and production closure 
Engine execution layer for V2 replication protocol:
- RebuildInstaller: full state handoff (dirty map, WAL, superblock, flusher)
- TruncateToLSN: exact safety predicate (checkpointLSN == truncateLSN),
  ErrTruncationUnsafe escalation to NeedsRebuild
- SyncReceiverProgress: unconditional Store for post-rebuild alignment
- V2StatusSnapshot: CommittedLSN = nextLSN-1 for sync_all

V2 bridge real I/O executors:
- TransferFullBase: TCP streaming + RebuildInstaller + second catch-up
- TransferSnapshot: SHA-256 verified streaming to disk
- TruncateWAL: ErrTruncationUnsafe detection + escalation
- StreamWALEntries: rebuild-mode TCP apply

Engine executor interfaces:
- CatchUpIO.TruncateWAL, RebuildIO.TransferFullBase returns achievedLSN
- CatchUpExecutor truncation-only skip, NeedsRebuild escalation
- RebuildExecutor uses achievedLSN for progress tracking

Design docs reorganized: superseded planning docs removed, protocol
truths and closure map added.

pingqiuandClaude Opus 4.6 46faf0f7e3 feat: Phase 09 P0 — production execution closure plan 
Execution-closure targets:
- P1: TransferFullBase — reuse rebuild.go TCP protocol
- P2: TransferSnapshot — checkpoint image + WAL tail
- P3: TruncateWAL — AdvanceTail + superblock update
- P4: Runtime ownership — V2 orchestrator drives execution

Key reuse sources identified:
- rebuild.go: rebuildFullExtent (client), RebuildServer (server)
- wal_writer.go: AdvanceTail
- flusher.go: updateSuperblockCheckpoint
- blockvol.go: ScanWALEntries (already wired)

Slice order: full-base first (highest value), then snapshot,
then truncation, then runtime ownership.
