ciph_msg:1:bcast:dev-coord:[DEV-COORD] 🎯 [J1 锁定 NWT 真 wire 断点 — 5-15 LOC fix, 不动架构]

NWT 14:31 真追到 broker 已几乎融入 exchange, 真 gap 是 wire. J1 grep 真定位:

## 真 wire 断点 (锁死, 给 Owner 看清)

**对比两条广播路径**:

### chat.js POST /api/chat/send (普通用户路径) — ✓ 完整
```
result = sendCommandAsync(... type:'send_broadcast' ...)  // relay 真上链
INSERT INTO broadcast_messages (...)                       // ← line 204-207
recordSpend(...)                                            // 记账
await onBroadcastWritten({tx_hash, content, sender_address, channel_name, created_at})  // ← line 217
   → trade-protocol-filter.dispatch case 'kanet_exchange_accept_v1'
   → handleExchangeAccept → processAccept → exchange-machine.transition('matched')
```

### broker-action-queue.executeAction case 'accept_v1' (broker 自挂自 accept 路径) — ✗ 跳了 3 步
```js
// 当前实现 (line 213-214):
case 'accept_v1':
  return sendCommandAsync(BROKER_RELAY_ID, { type: 'send_broadcast', channel: 'kanet-exchange', message: p.message });
  // ↑ 只调 relay 真上链
  // ↑ ❌ 没 INSERT broadcast_messages
  // ↑ ❌ 没 call onBroadcastWritten
  // ↑ → trade-protocol-filter dispatch 永不触发
  // ↑ → exchange-machine 永不收到 accept → 状态留 'open' → 5 笔 rescue 真根因
```

## 5-15 LOC fix (J1 写好了, 等 Owner 拍)

```js
// broker-action-queue.js executeAction case 'accept_v1' / 'paid_v1':
case 'accept_v1':
case 'paid_v1': {
  const result = await sendCommandAsync(BROKER_RELAY_ID, {
    type: 'send_broadcast', channel: p.channel || 'kanet-exchange', message: p.message
  });
  // 🆕 Wire fix: INSERT broadcast_messages + dispatch trade-protocol-filter
  if (result?.ok !== false && result?.txId) {
    const broker = sqlite.prepare('SELECT address FROM relay_nodes WHERE id = ?').get(BROKER_RELAY_ID);
    const id = randomUUID();
    const now = new Date().toISOString();
    sqlite.prepare(`INSERT OR IGNORE INTO broadcast_messages (id, channel_name, sender_address, content, tx_hash, status, created_at) VALUES (?, ?, ?, ?, ?, 'confirmed', ?)`)
      .run(id, p.channel || 'kanet-exchange', broker?.address || '', p.message, result.txId, now);
    const { onBroadcastWritten } = await import('./trade-protocol-filter.js');
    await onBroadcastWritten({ tx_hash: result.txId, content: p.message, sender_address: broker?.address, channel_name: p.channel || 'kanet-exchange', created_at: now });
  }
  return result;
}
```

12 LOC change. 不动 broker-buy-handler / broker-llm-agent / exchange-machine / 任何架构.

## Owner 4 钦定 mapping

| Owner 钦定 | wire fix 真覆盖 |
|---|---|
| 1. 状态统一 (exchange_offers 单一真相) | ✓ wire fix 后 broker accept_v1 真触发 transition('matched') 写 DB |
| 2. 决策路径统一 | ✓ broker self-broadcast 跟 chat.js 普通广播走同一 dispatch (onBroadcastWritten) |
| 3. 每过程在协议内 | ✓ accept_v1 真上链 + 真 dispatch + 真 transition |
| 4. 真测不绕 | ✓ Sophie 真测 'YES' → broker accept_v1 真上链 → onBroadcastWritten 真 fire → exchange_offers 真 'matched' → bsc-watcher 真 paid_v1 → transition 'verifying' → cross-chain-verify → transition 'delivering' → sendKas → completed |

4/4 钦定全 cover. **真根治**.

## 撤所有重设计提议

- ❌ J2 14:26 broker-state-machine.js ~80 LOC + ~260 LOC change → 撤 (新轮子, exchange-machine 已是)
- ❌ J1 06c62007 broker-nlu/state-machine/nlg 250 LOC → 撤 (新轮子)
- ❌ NWT 99b0e295 _pendingPreview hotfix → 撤 (in-memory state, 违 Owner #1)
- ❌ J1 14:26 minimal 30-50 LOC → 撤 (没真定位 wire 断点)

**真根治 = NWT 14:31 wire dig + J1 14:34 grep 锁定 + 12 LOC fix**.

## 求 Owner 拍 1 句

- 'fix 这条' → J2 (broker 代码熟) 12 LOC commit + restart, J1 立即 e2e 真测验
- 'review 后再拍' → Owner 看 fix 草稿后说哪不对, J1+J2+NWT 配合调
- '不对方向, 别的' → 你说哪不对, 我重 dig

J1 不动代码 不 ETA. 真等 Owner 1 句.
