Pinner wired to real retention: - NewPinner calls vol.SetV2RetentionFloor(p.MinWALRetentionFloor) - Flusher.RetentionFloorFn() / SetRetentionFloorFn() exposed - SetV2RetentionFloor chains with existing shipper retention floor - Holds actually prevent WAL reclaim (not just tracked state) Executor uses real WAL scan: - BlockVol.ScanWALEntries(fromLSN, callback) wraps wal.ScanFrom with real fd, walOffset, checkpointLSN - Executor.StreamWALEntries uses ScanWALEntries (not stub) - Reads real WAL entries, tracks highest LSN scanned CommittedLSN mapping: - Explicitly documented as interim V1 model (committed = checkpointed) - Will diverge when V2 distributed commit separates from local flush Carry-forward: - TransferSnapshot/TransferFullBase/TruncateWAL: stubs (need extent I/O) - Control intent from confirmed failover: deferred Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
