## 但 Trader-B Mind/Brain 同时 freelance 给 Martin

console.log 17:32-17:35 Trader-B AI → 给 Martin 一连串 Mind LLM 自由发挥:

```
17:32:36 AI → "兄弟，这价格不对。现在市价是 0.033686..."  (合约逻辑外的价格质疑)
17:33:00 AI → "我是 KANet Broker，不是卖家。我只负责..."  (角色 confusion)
17:33:20 AI → "现在最优卖单只有 50 KAS 在 0.034246..."  (报价跟 broker 报价不一致)
17:33:53 AI → "兄弟，先别急着转。现在市场没卖单（缺货）..."  (跟 broker 矛盾)
17:34:16 AI → "兄弟，搞混了。我是帮你买币的 Broker..."  (角色再 confusion)
17:34:49 AI → "兄弟，刚才说没卖单，现在说有，数据对不上啊..."  (Mind 跟自己矛盾)
17:35:18 AI → "我没太听明白, 能换个说法吗?"  (broker 装糊涂)
```

## 根因 (不是 UTXO race)

Trader-B 有两套独立 reply 系统:

1. **broker-buy-handler** (deterministic, 由 `/api/agent/reply` 调) — 报价/接单/付款指引
2. **Mind reactive** (LLM, 由 mind-manager 自驱动) — 自由发挥 chat

Martin 发 1 条消息 → 两套系统**都看见**:
- broker-buy-handler 命中 BUY_REGEX/CONFIRM/PAID → 进 queue, OK
- Mind reactive 也跑 → Brain 拿 message + skills 混合 reply → 自由发挥

后果: broker-buy-handler 文案 ("📋 报价 + 你前面 N 人") 跟 Mind 文案 ("市价不对 / 没卖单 / 别急着转") **同时**发到 Martin. Martin 完全晕.

## 这才是 Bug 7+ 真本质

不是 UTXO race (queue 已解), 是 broker handler ↔ Mind LLM **职责重叠** + **同时发声**.

Q6 升级 (Mind 也入队) 不解此问题: Mind 还是会发自由发挥 DM, 只是不撞 UTXO. Martin 还是收 broker handler + Mind 矛盾文案.

## 真治本

**Trader-B is_dex_broker=1 时禁用 Mind reactive proactive DM** (mind-manager 检 is_dex_broker flag).

或: Trader-B Mind 只允许 reply broker-buy-handler 没 match 的 fallback (handler return null 时才让 Mind 跑). 当下逻辑应该已经这样 (conversations.js 120-152 broker 命中早 return), 但实测 Mind 还在跑 → 说明 Mind 不走 `/api/agent/reply` 路径, 是 mind-manager 独立 schedule.

需查 agent-mind/src/mind-manager.js 看 Trader-B reactive 触发逻辑.
