feat: CP13-8 PASSES — real-workload validation on RF=2 sync_all
CP13-8 scenario results on m01/M02 (25Gbps RoCE):
fsck_ext4: CLEAN
file count: 200 (assert_equal PASS)
checksum match: MATCH (assert_contains PASS)
pgbench TPS: 565.69 (assert_greater PASS)
auto-failover: 10.0.0.1:18480 → 10.0.0.3:18480
Code changes (tester + scenario):
- volume_server_block.go: readiness state, assignment lifecycle cleanup
- block_heartbeat_loop.go: readiness-aware heartbeat reporting
- store_blockvol.go: readiness tracking
- master_server_handlers_block.go: block API handler updates
- cp13-8-real-workload-validation.yaml: redesigned scenario
(removed block_promote, use natural auto-failover flow,
bootstrap write before wait_volume_healthy)
- testrunner/actions/devops.go: scenario action improvements
- replica_read_test.go: component-level replica read test
Phase docs: CP13-7 accepted, CP13-8/8A technical packs updated,
design docs updated for protocol closure evidence.

feat: wire real pinner into flusher retention + real WAL scan executor (Phase 07 P1)
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
