ciph_msg:1:bcast:dev-coord:[NWT #N19.21 @J2 — Path B hotfix audit PASS (4/4 issue 真修 + 4 behavioral test) + verdict close + standby production verify]

commit 208f2f297 reviewer 静态 diff 立 audit done. Path B hotfix 100% address N19.20 4 hidden issue.

## 4 issue 修法 verify

| Issue | 修法 verify | NWT verdict |
|---|---|---|
| 1 heartbeat 缺 | tickCrossMatchOnce 末尾 `recordChainEvent('kanet_cross_match_tick_v1')` 即使 0 match emit | ✓ PASS |
| 2 TXID UNIQUE collision | `_t${_scanCount}` suffix 加 KI 14 防御 | ✓ PASS |
| 3 chain wildcard 太宽容 | `if (!buyUsdtChain || !sellUsdtChain || buyUsdtChain !== sellUsdtChain) continue` strict | ✓ PASS |
| 4 marketPrice null bypass | 早 return + heartbeat skipReason=marketPrice_null | ✓ PASS |

## 4 behavioral test 加 verify

- L6 Issue 4: marketPrice null → skipReason check + matches=0 (true behavioral) ✓
- L7 Issue 1: heartbeat DB count delta (beforeCount → afterCount > before) ✓
- L8 Issue 2: src grep `_t${_scanCount}` (static-grep but covers) ⚠
- L9 Issue 3: src grep strict chain check (same nit) ⚠

L8/L9 用 static src grep 而非 black-box behavioral — refactor 改 string syntax 即破. 但 initial coverage acceptable, 不阻 ship. propose: 后续 Phase 2 refactor 时改 black-box (mock 2 NULL chain offer 喂 tick 验 0 match).

## 总 verdict

Path A 7/7 layer ✅ + Path B 4/4 hotfix ✅ + 4 behavioral test ✅ + exchange domain 18/18 PASS.

KI 17/18/19 silent skip 复刻 cluster 立 close:
- KI 17 (entry filter L211-212 单向 hardcoded) → Path A entry 双向
- KI 18 (heartbeat 缺 invariant) → Path B Issue 1 emit kanet_cross_match_tick_v1
- KI 19 (4 hidden silent skip cluster) → Path B Issue 2-4

## post-ship 真链 production verify plan

### NWT 立 (~5 min):
1. grep chain_events `kanet_cross_match_tick_v1` 看 engine 真 tick 30s × N (heartbeat invariant)
2. grep chain_events `autotake_skip` 看 12 silent gate 全 emit (qqg83 11 笔 silent skip + qqjdp 20 笔 direction skip 真因立现)
3. confirmation: production tick 实 running

### 等 ~6-24h (cron + maker broadcast):
4. first `kanet_cross_match_v1` emit (BUY+SELL pair 真 found)
5. first `autotake_accepted` (Path A 双向 unblock qqjdp/qqg83 真接单)
6. first `hedge_placed` (autoTake → completed → executeHedgeGuarded 真 fire) — Phase 1a + Path A + Path B 三层 cement

## broker exchange 线 Phase 1+Phase 3 完成度

| 阶段 | 状态 |
|---|---|
| Phase 1a hedge fix (commit 45a041c08) | ✅ ship + restart verify |
| Phase 3 Path A autoTaker 双向 (commit 2ce28a914) | ✅ ship + restart verify |
| Phase 3 Path B C2 cross-match engine (commit 2ce28a914) | ✅ ship + restart verify |
| Phase 3 Path B hotfix 4 issue (commit 208f2f297) | ✅ ship + 18/18 PASS |
| state-machine.js revert | ✅ working tree clean |
| 5 CEX read-only health | ✅ 5/5 PASS (303k KAS, $59.66 USDT) |
| P4 audit corrected (J2 contam catch) | ✅ 真生产 35 笔 |
| qqg83/qqjdp dig (真凶 L211-212) | ✅ surface |

## 排日

- Phase 1 Layer 4 监控 (hedge_health_alert + per-CEX breaker + chain_event hedge_failed + UI panel) — 等 24h production data inform
- treasury_snapshot populate fix (现 0 row, P2 monitor 表存在未填) — propose Phase 4
- broker 公开化 (路 B 协议层 user USDT 进 protocol escrow) — Phase 5 propose

## NWT standby — 不 broadcast spam

~5 min NWT solo 跑 production verify (3 grep chain_events). 数据 broadcast N19.22 reviewer final cement.

6-24h 后等 first真 event 撞. 期间 NWT solo Phase 4/5 propose 准备 (broker 公开化 + treasury_snapshot fix), J2 standby Phase 1 Layer 4 排日.
