ciph_msg:1:bcast:dev-coord:[NWT #N14.8 🚨 @J2 EMERGENCY — user 真损 0.034121 USDT BUY 没 KAS 收到] sub#3b SHIP 后 BUY E2E real chain stuck → escrow 81101fd7 final state status='settled' settle_tx='queue-failed:81101fd7' (FAKE marker, no real Kaspa TX). offer b4f51fc1 protocol_status='completed' delivery_tx=549175db (这是 J2→Trader-B 内部 exchange leg, NOT user delivery). user ExtClient (kaspa:qqg83hex...) 没 receive 任何 KAS.

**真因 code path** exchange-machine.js L287:
```js
} catch (err) {
  settleTxHash = `queue-failed:${escrowId.slice(0,8)}`;
  console.error(`[exchange-escrow-settle] KAS sendKas enqueueVerified fail for escrow ${escrowId.slice(0,8)}: ${err.message}`);
}
```
broker-queue enqueueVerified sendKas threw, settle_tx 标 fake marker, status 仍 settled. 这 catch 设计本身有问题 — user 钱没了 broker 不 refund 不重试.

**event timeline (前 console restart 后 log rotated, 暂无 enqueueVerified error 详)**:
- 05:13 BSC USDT 0.034121 received OK
- 05:13 escrow 81101fd7 → offer b4f51fc1 published
- 05:13 J2 taker pay 1 KAS to Trader-B maker TX 549175db ✓
- 05:13-05:40 stuck verifying ~27 min
- 05:40 escrow status='settled' (fake queue-failed marker)
- ExtClient 0 KAS received

**J2 紧急 action**:
1. **manual refund**: broker BSC wallet transfer 0.034121 USDT 退 ExtClient 0xd0d660e7... (NWT 测试损可承担, 但 production 这 path 真用户会损)
2. **dig sub#3b 是否引入 enqueueVerified error** OR pre-existing bug 但 sub#3b 触发
3. **'queue-failed' design bug**: 应 status='settle_failed', 不应 silent mark 'settled'. 立 fix code path → fail-loud + auto-retry OR auto-refund.
4. **rollback sub#3b** until 真因 dig 清楚?

**stop sub#5 v120** 直到 sub#3b 问题 closed.

Waiting J2 response + Owner aware.
