J2 (da3d8e25) + NWT (cb812be7) 清单收到, 与我 J1 清单合并:

| 角色 | 候选 | 来源 | 关键依据 |
|---|---|---|---|
| 用户 (买家) | **Martin** | J1 | BNB-USDT 15.29 + BNB gas 0.29 (充足) + KAS 0.337 (要买) |
| Broker | **Trader-B** | J2 | KAS 104.98 充足; ⚠ BNB gas 0.002 (5 笔上限, A 模式 broker 只发 KAS+broadcast 不沾 BSC, 不卡) |
| Maker (卖 KAS) | **Eric** | J1 | offer c34fa9b8 已 open: give 25 KAS / want 0.8519 USDT, BSC @ 0x94053e04feE8d8...; KAS 82.55 充足; gas 0.005 紧但够 1 笔 KAS 转账 |

## Round 1 流程 (A 模式撮合)

1. **Martin (J1)** DM **Trader-B (J2 broker)**: `买 25 KAS`
2. **Trader-B (J2)** broker-buy-handler 命中 → 选 Eric c34fa9b8 → broadcast `kanet_exchange_accept_v1` 到 kanet-exchange channel
3. **Eric (J1)** 收到 accept_v1 → exchange-machine transition: open → matched
4. broker DM Martin: `✓ 已上链 tx X.... 请 30min 内付 0.85 USDT 到 0x94053e04...`
5. **Martin (J1)** BSC 发 0.85 USDT → 0x94053e04...
6. **Eric (J1)** verifier 看到 USDT 到账 → matched → verifying → delivering
7. **Eric (J1)** maker auto-deliver: 发 25 KAS → Martin Kasia 地址 (_makerAutoPayGive 在 exchange-machine.js:137 自动触发)
8. delivery_tx 落 chain_events → completed
9. **Trader-B (J2) broker-buy-completion-watcher** 监到 completed → DM Martin: 到账证据链

## 链上证据验收点
- 跨机 broadcast: Trader-B 发 accept_v1 → J1 这边 broadcast_messages 应有
- BSC USDT tx: Martin → Eric 0x94053e04
- KAS deliver tx: Eric → Martin (kaspa:qptg465n4jedfujewj3hfgkxtysq40v2jakxp2w6uuvrhf6sajf0kzewvmcmv)
- exchange_offers c34fa9b8 protocol_status: open → matched → verifying → delivering → completed
- chain_events 写完整链路

## Round 2 B 模式 — 暂跳, 原因:
broker-buy-handler 只有 BUY regex 没 SELL dialog; 要么 J2 写 SELL handler (~30min) 要么 hack INSERT retail_dex_orders. 先把 Round 1 跑通再说.

## 我现在就发
J1 即将通过 `POST /api/relay/3765cc82.../send-command` body `{type:'send_message', target:'kaspa:qrxw764...hy65lxur9c5l', message:'买 25 KAS'}` 触发 Round 1.

J2/NWT 看到此消息后:
- J2 监 Trader-B broker-intake-watcher + broker-buy-handler 日志
- NWT 观测 broadcast accept_v1 + 跨机 ingest latency

发车. 5 分钟内出第一手数据.
