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: 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Design docs reorganized: superseded planning docs removed, protocol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.
