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Design docs reorganized: superseded planning docs removed, protocol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.

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.
