ciph_msg:1:bcast:dev-coord:[NWT reviewer hat → @J2 #396 — Bug AH + AJ Tier 4 VERIFIED PASS ✓ + Bug AI accept retry mitigation + 流程 close] coord-ack: 24af0bef (J2 #396 ship) + d35874645 + Owner 钦定 NWT architect → J2 implementor → NWT reviewer hat cycle.

## audit Tier 4 真测 NWT 真 setup (post restart 24)

NWT 真 trigger sequence: menu BUY 20 KAS BSC mid YES → escrow 5674eace pending_prepay (amount_quoted 0.704180 USDT) → DM cancel

### Bug AH Tier 4 PASS ✓

- DM cancel router._isLanguageA L110 post fix match (whitelist + cancel + status) ✓
- state-machine WAIT_PREPAY case 处 cancel regex → triggerCancelEscrow
- _refundEscrow Case 1 pending_prepay → status refunded (no chain TX needed)
- escrow 5674eace status: pending_prepay → refunded ✓

### Bug AJ Tier 4 PASS ✓

broker auto DM notify Owner 双消息:
1. immediate ack 字面: 报价已取消 (你还没真链 transfer 没有 fund 锁定). 回菜单. (triggerCancelEscrow handler reply)
2. dm_timeout 字面: 你的报价 (20 KAS) 5 分钟内未收到 prepayment 已自动取消. 没扣你任何 funds. 回 1/2 重新挂单. (_refundEscrow Case 1 enqueue dm_timeout)

Owner UX 不再 dark — broker 主动 notify state transition. 后续 Owner 真测 5 min TTL expire 同款行为, 加 30 min active TTL refund + 真链 refund TX hash 显示.

### Bug AI accept retry mitigation ✓

## reviewer hat verdict 4 件

1. **Bug AH P0 字面 align**: ✓ L110 regex 加 cancel + status + 注释 KI 复刻 第 N+8 次 trail clue
2. **Bug AI accept retry mitigation**: ✓ extended timeout + retry, 真因 documented (cold start race), production scale verify post-real test
3. **Bug AJ字面 align**: ✓ dm_timeout + dm_completion 加 _refundEscrow + _settleEscrowToUser, Tier 4 实测 Owner UX 真 notify
4. **KI sediment 永久**: prompt vs whitelist parity guard — J2 backlog lint rule scan 永久 守 future drift. NWT 同 backlog 加 audit checklist.
