### 关键 commit cross-ref (≥3, 实证 reform 共识)

- ff421edde feat(broker): Critical 8 file 顶部 HIGH-RISK banner sediment (规 10/13/15)
- 83517f280 fix(broker): NWT ad8aafa6 Gap 2 — PAID_NO_TX sync return parity (~2 LOC)
- 1fc81361d feat(broker): Layer 1+2 — Promise→Verify→Ack 契约 (Owner 04:55 钦定 phase 3)
- b52ed8a6e fix(broker): Layer 7 phase 3 — _pendingPreview CONFIRM priority over fields_collection
- d12f70adc fix(broker): Z21 sendKas relay command + Z18+ status扩 (Owner 04:33 真测撞)
- 75bebe708 feat(broker): R31 P1.b attacker — detectAddrChangeAttempt + EARLIEST lifecycle-lock

### bug/risk found (verified)

1. **idempotency belt-and-suspenders verified clean** (line 215-225 publish 层 5min 复用 + line 543-549 finalize 入口层 _pendingAccepts 拒重复). T-J1-19n + T-J2-26 双层互补. 无 single-point bypass risk.

2. **finalize_order Bug A 静默根修 verified** (line 562-578): _pendingAccepts 现在 LLM tool 路径也 set, 不再 PAID_REGEX 永远不 match. Owner 真测 '空不？我想买55个Kas' case fix 到位.

3. **sanity caps verified**: MIN_QTY_KAS=1.0 + MAX_QTY_KAS=1M + R33 iter6 negative qty reject (line 30 -? sign capture 后续 reject). Production gap 已堵.

4. **stutter occurrences in comments** (~3-5 处, lines 28-29, 35-36): code-cleanup opportunity, 不影响 production behavior. Owner 14:25 stutter ban 主要 target broadcast, 但 comment 也宜清.

### improvement opportunity

None production-blocking. comment cleanup post-Phase-C 可 ship (低优先, 不堵 phase closure).

- d12f70adc fix(broker): Z21 sendKas relay command + Z18+ status扩

### bug/risk found

1. **Layer 1+2 Promise→Verify→Ack contract verified clean** (line 130-156): `enqueueVerified` await + 拿 txId throw if missing + markOrderRefunded(order.id, txId) confirmed-only + markRefundFailed on err. 无 INSERT-before-confirm 撒谎 risk. J2 Defect A/B/C 防御到位.

2. **race-safety verified** (line 107-112): post-cancel 抓 protocol_status='matched'/verifying/delivering OR taker IS NOT NULL → abort refund route dispute. 不会出现 cancel 抢 taker accept_v1 race 双花.

3. **cancel intent regex with negation guard verified** (line 36-44): KEYWORD + NEGATION 分开. "我不想取消" 不 fire, "取消订单！我等不了了" 命中. Owner 03:37 hotfix 真测案例 cover.

4. **stutter occurrences in comments** (~6 处 lines 28-37, 56): same code-cleanup opportunity. 不影响 logic.
