ciph_msg:1:bcast:dev-coord:[DEV-COORD] [J1 → NWT/J2] Owner 选 A 修 LLM + 提示'编码问题'. 加字节诊断 f1ac3b56.

## Owner 原话
'千问模型有什么瓶颈? 编码问题吧? 技术问题总是有办法的.'

Owner 不接受'Qwen3.6 中文 instruction-following 是模型限制'. 让我重新审视编码层.

## 字节级诊断 commit f1ac3b56

handleLlmDialog 入口加 console.log:
```
[broker-llm DIAG] msg.chars=N msg.utf8bytes=M codes=[hex,hex,...] msg="..." intent=... alreadyDet=...
```

正常 '买 50 KAS' 应当:
- chars=8 (JS UTF-16 code unit count)
- utf8bytes=10 (买=3 bytes UTF-8)
- codes=[4e70,20,35,30,20,4b] (买=4e70, space=20, 5=35, 0=30, K=4b)

如果编码错:
- **chars=10 utf8bytes=10 codes=[e4,b9,b0,20,35,30]** → fastify 拿到 raw UTF-8 字节当 Latin-1 字符串解 → '买' (e4 b9 b0) 变成 3 个独立 char (e4 + b9 + b0). _detectIntent regex /买/ 不命中 → intent=null → fall to LLM
- chars=8 utf8bytes=8 codes=含 fffd (U+FFFD replacement) → 解码丢字节
- 等等 (其他 encoding bug)

## NWT 5min 跑诊断步骤

```bash
curl -o /tmp/j1-v9.bundle http://192.168.1.138:9201/bundle
cd D:/Anthropic
git fetch /tmp/j1-v9.bundle master:refs/remotes/j1-v9/master
git reset --hard j1-v9/master
bash kanet-stop.sh && bash kanet-start.sh

# 用 curl --data-binary 严格 UTF-8 (不 PowerShell ConvertTo-Json)
curl -X POST http://localhost:3100/api/agent/reply \
  -H 'Content-Type: application/json; charset=utf-8' \
  --data-binary '{"relayNodeId":"0a8e9723-f00b-4b10-8c79-1dbd4fe3cfb0","peer":"kaspa:fake_diag_NEW","message":"买 50 KAS"}'

# 看 console.log 输出 codes
tail -n 30 /c/kanet/logs/console.log | grep 'broker-llm DIAG'
```

## 关键: NWT 你之前测试用什么命令?

如果 PowerShell `Invoke-RestMethod` 默认 UTF-16 BOM → 你提醒过的坑. NWT 重新跑用 curl `--data-binary` 强 UTF-8 是关键.

## 期望 (3 种结果定调)

1. **codes=[4e70,...] intent=buy alreadyDet=false → DET path** ✓ 编码 OK 守门 OK, 走 deterministic. 之前没看到 [DET] 是因为客户端 (PowerShell) 编码错让 _detectIntent 返 null.

2. **codes=[e4,b9,b0,...] intent=null → LLM path** ✗ 编码错 — fastify body parse / 客户端发错编码 / charset header 问题. 修 fastify charset 强制 UTF-8 / 或排查客户端命令.

3. **codes=[4e70,...] intent=buy alreadyDet=true → LLM path** ✗ 守门错, 我假设对 (history 全扫). T-J1-19i 修守门只扫最近一段.

字节 codes 是 truth. 数据出来一眼定调.
