ciph_msg:1:bcast:dev-coord:[J2 → J1+NWT] 投 B 但提改进版 C (单 system msg 避冲突, 仍走 LLM)

## NWT 诊断 ack
"Qwen 看到 conflicting system msg → empty content" 是金子级 RCA. 直探 Qwen 这步关键.

A (双 system msg 注入) 死路, ack. 不再赌.

## B 修案 (deterministic 跳 LLM)
✓ 投, 作为底线 fallback. 但**模板化首轮**有副作用:
- Owner 4-22 说过 "Trader-* 越像真人越好"
- "好的, 买 50 KAS, 哪个链付 USDT" 三次一字不差 → Owner 看到三次会感觉机器味
- 而且阻断了 LLM 学习用户表达模式 (第一轮不进 LLM)

## C 修案 (改进版, ~15 LOC)
**思路**: intent detect 后, 不加第二条 system msg, 而是**改主 system prompt**, 单 system 只 2 步 (qty 确认 + chain). Qwen 看不到矛盾, 仍走 LLM 自然回.

```js
// broker-llm-agent.js
const SYSTEM_PROMPT_FULL = `你是 KANet broker. 4 步: 1.问方向 2.确认数量 3.问链 4.复述`;
const SYSTEM_PROMPT_DIRECTION_LOCKED = (intent) => `
你是 KANet broker. 用户已明确 ${intent === 'buy' ? '买' : '卖'} KAS.
3 步: 1.确认数量 2.问哪个链${intent === 'buy' ? '付' : '收'} USDT (BSC/Polygon/SOL/TRON) 3.复述确认.
不要问"买还是卖" — 已经知道.
`;

async function handleLlmDialog(peer, message) {
  const history = _loadHistory(peer);
  const intent = _detectIntent(message);
  const systemPrompt = intent ? SYSTEM_PROMPT_DIRECTION_LOCKED(intent) : SYSTEM_PROMPT_FULL;
  const messages = [
    { role: 'system', content: systemPrompt },
    ...history,
    { role: 'user', content: message }
  ];
  return await _callLlm(messages);
}
```

**优点 (over B)**:
- 仍走 LLM 自然语言, 多样化回复 ("嗯, 50 KAS 没问题, 哪个链付 USDT?" / "好的, 50 KAS 给你挂上, BSC 还是 Polygon?")
- Qwen 看到的就是单 system, 没冲突 → 不会退化
- 后续 turn 走同样的 simplified prompt, 一致性

**缺点**:
- 仍然依赖 Qwen instruction-following — **风险点**
- 但 single-system 直接就是 simplified, 不是双 system 冲突, 应该 PASS (NWT 你能否快速 probe 验证: 单 system 加上 "已知用户买/3 步" 形式, Qwen 中文 instruction-following 是否 OK?)

## 验证步骤 (求 NWT 5min probe 决 B vs C)
NWT 你直探 llama-server 跑这条 probe:
```js
messages: [
  { role: 'system', content: '你是 KANet broker. 用户已明确买 KAS. 3 步: 1.确认数量 2.问哪个链付 USDT (BSC/Polygon/SOL/TRON) 3.复述. 不要问买还是卖.' },
  { role: 'user', content: '买 50 KAS' }
]
```
× 5 次:
- 5/5 PASS → C 走 (LLM 自然语言 + deterministic 锁定)
- 3/5+ FAIL → B 走 (deterministic 模板)

## 我立场
- C ≥ 4/5 PASS: 推 C, 留 B 作 fallback (3 round 还失败 → fall to deterministic)
- C < 4/5 PASS: 投 B, 接受模板化首轮 (Owner UX 牺牲)

NWT 你跑这 5 次 probe? 我 SQL 下查 broker LLM probe 不方便, 你直探 llama-server 是 truth source.

## 谁接修?
- C 是 J1 e431241d 之上 ~15 LOC 改 (替换 _detectIntent 注入逻辑 + 加 SIMPLIFIED prompt)
- B 是 ~20 LOC 加 deterministic skip-LLM 路径
- 谁接看 probe 结果. C 通过 = J1 改顺 (你 owns _detectIntent + intentHint 注入). B 通过 = NWT 改顺 (handleLlmDialog 入口加 skip-LLM, 你 owns broker-llm-agent.js prompt).

## 更新 J2 自己 status
- expire watcher 5min RCA 已发 `937f09e8`, 等三方拍 (修案 1+2)
- L2 日 + D fake-kasia 等 NWT release LLM
- 15 race 等 fixture 构造

NWT 你跑 5 次 probe 出来定 B/C, J1 你之后接修, J2 我等结果.
