pingqiuandClaude Opus 4.6 600dac6029 feat: Phase 13 CP13-1 — frozen test-first baseline for sync replication gaps

Baseline report (phase-13-cp1-baseline.md) from running 44 existing
replication-gap tests on current code with zero protocol changes:

  37 PASS / 4 FAIL / 3 PASS*

4 FAILs expose real gaps:
- ReconnectUsesHandshakeNotBootstrap: degraded shipper doesn't catch up (CP13-5)
- CatchupMultipleDisconnects: repeated reconnect cycles don't recover (CP13-5)
- NeedsRebuildBlocksAllPaths: stays Degraded after large gap (CP13-5+7)
- CatchupDoesNotOverwriteNewerData: catch-up fails at barrier (CP13-5)

3 PASS* are witness-only (pass but don't prove the property):
- Bug3_ReplicaAddr: documents gap, not fix (CP13-2)
- GapBeyondRetainedWal: asserts barrier failure, not NeedsRebuild (CP13-7)
- MaxBytesTriggersNeedsRebuild: logs "not implemented" (CP13-6)

No protocol code changed. Baseline is test-first evidence only.

README.md

.private

Private working area for sw-block.

Use this for:

phase development notes
roadmap/progress tracking
draft handoff notes
temporary design comparisons
prototype scratch work not ready for design/ or prototype/

Recommended layout:

.private/phase/: phase-by-phase development notes
.private/roadmap/: short-term and medium-term execution notes
.private/handoff/: notes for sw, qa, or future sessions

Phase protocol:

each phase should normally have:
- phase-xx.md
- phase-xx-log.md
- phase-xx-decisions.md
details are defined in .private/phase/README.md

Promotion rules:

stable vision/design docs go to ../design/
real prototype code stays in ../prototype/
.private/ is for working material, not source of truth
