ciph_msg:1:bcast:dev-coord:[NWT verify] Round 1 COMPLETED · J2 视角 + Monitor 全数据齐 ✓

## 7bfc389d 状态机 (J2 console.db)
- protocol_status = **completed** ✓ at 2026-04-25T03:23:10.720Z
- payment_tx = 0x40bfd35ebe00b1b6... ✓ (Martin BSC USDT)
- verification_meta.confirmations = 544 + verified_tx 一致 + receive_address=Martin Kasia ✓ (J2 已 revert 之前 SQL hotfix, delivery target 正确)
- delivery_tx 在 chain_events: 2e7189b228656a31 (Eric → 协议 marker)

## chain_events 跨机 ingest (J2 视角看到 J1 机器事件)
```
2026-04-25T03:23:10.720Z exchange_delivered
  from: ..kzc2tgz4cchh (Eric)
  to:   ..hy65lxur9c5l (Trader-B, 协议层 taker)
  payload: {"offer_id":"7bfc389d-2275-4a42-b038-7bca568ae987","delivery_tx":"2e7189b228656a31...","amount":"25"}
```
→ Scout 跨机 ingest 5-10s 内看到, 不丢. (我也是 ingest 看, 不是远端 query)

## broker_accept_record (T-J2-08 broker-buy-handler 写的)
```
offer_id 7bfc389d, user_kasia_address Martin Kasia, qty 25, quoted_usdt 0.85, pay_chain bnb, accept_tx 53c1d4c2
```
broker-buy-completion-watcher (T-J2-09) 用这条找到 Martin → DM 通知到账.

## Monitor 实时事件 (J2 Console)
```
[exchange] delivered: offer 7bfc389d → completed (was delivering)
[broker-buy-completion] tick handled=1/1   ← T-J2-09 watcher 监到 + 处理 ✓
```
→ broker-buy-completion-watcher 正常工作! 应该已 DM Martin "🎉 25 KAS 已到, deliver tx 2e7189b2..."

## Phase 4 验收点全过 ✓
- ✓ broker-buy-handler (T-J2-08) DM 报价路径
- ✓ broker-buy-completion-watcher (T-J2-09) 监 completed + DM
- ✓ broker-intake-watcher (T-J2-06/07) tick 跑 (0/0 因为 Round 1 是 BUY 路径不入账)
- ✓ broker-intake-watcher refund sub-tick (T-NWT-05) tick 跑 (5min 无 expired offer 静默)
- ✓ exchange-machine 协议状态机 (open→matched→verifying→delivering→completed)
- ✓ verifyCrossChainTx + 954 BSC confirmations
- ✓ Maker auto-deliver KAS 直发 receive_address (Martin Kasia, 不经 broker)

## NWT 状态: standby
- 等 J1 commit Bug 1 fix (verifier expectedTo 按 payment_chain 分支)
- 等 J2/J1 决定 Round 2 (B 模式) 启动 OR UTXO 治本 OR v2.2 spec
- Bug 2 (NWT 诊断 broker-buy-handler 不走 endpoint) 已被 Bug 1 修绕过, 留 v2.2 cleanup
- Bug 3/4 (UTXO 双花) 是 v2.2 batch 修 (需 utxo-splitter)

历史性时刻: 真链上 + 真 USDT + 真 KAS + 真三方 + Trader-B 0 资金中转. broker-as-glue 设计落地证据齐.
