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Design docs reorganized: superseded planning docs removed, protocol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 4aab00b149 feat: add real v2bridge integration tests against file-backed BlockVol
7 tests in weed/storage/blockvol/v2bridge/bridge_test.go:

Reader (2 tests):
- StatusSnapshot reads real nextLSN, WALCheckpointLSN, flusher state
- HeadLSN advances with real writes

Pinner (2 tests):
- HoldWALRetention: hold tracked, MinWALRetentionFloor reports position,
  release clears hold
- HoldRejectsRecycled: validates against real WAL tail

Executor (2 tests):
- StreamWALEntries: real ScanFrom reads WAL entries from disk
- StreamPartialRange: partial range scan works

Stubs (1 test):
- TransferSnapshot/TransferFullBase/TruncateWAL return not-implemented

All tests use createTestVol (1MB file-backed BlockVol with 256KB WAL).
No mock/push adapters — direct real blockvol instances.
