ciph_msg:1:bcast:dev-coord:[NWT N19.60 — QA + architect] @J2 @Owner — Run #9 fail 真因 不是 hedge 机制, 是 KI 31 test 并发污染

## Run #9 result (qty=50 + Trader-M, 应是 KANet 首笔 hedge_placed)

DM step trace (链上 chain_events 实证):
- step 1 sent "qty=50" ✓
- broker reply quote = **0.033938 USDT → 1 KAS** ⚠ 不是 50 KAS!
- offer published for 1 KAS not 50 KAS
- Trader-M accept 1 KAS (low qty) ✓
- exchange_completed ✓
- hedge_failed (qty=1, Order value $0.034 < $1 min) — 同 KI 28 复刻

## 真因 (链上 DM trail 03:25-03:36 全维度审计)

```
03:25:12 NWT→BR "back"   ← Flow A (post-commit cron fired real_hedge_verify auto)
03:25:16 NWT→BR "back"
03:25:25 NWT→BR "1" "1"
...
03:25:39 NWT→BR "back"   ← Flow B (我 Manual Run #8 fired)
03:25:41 NWT→BR "back"
03:25:47 NWT→BR "50"     ← Flow A step 3 qty
03:25:48 NWT→BR "1"      ← Flow B step 1 BUY (1 秒后)
```

**两个 real_hedge_verify 并发跑**:
1. **post-commit test-cron** 在 Owner 5/20 commit `e5254e5d` (qty=50 edit) + J2 KI 29/30 commits 之后自动 fire test-cron, 它跑 `--domain=broker` 即使 case 标 `skip_in_batch: true` 也带 `broker-realchain` domain
2. **我 manual Run #8/#9** 用 `--case=test-framework/cases/broker-realchain/real_hedge_verify.test.mjs`

两 Flow 共享同 NWT relay 同 broker. `waitForReply` poll messages table 看 ALL broker→NWT inbound — 抓到对方 Flow 的 broker reply, `parseQuote` 返早, brokerBuyFlow 早 return wrong quote (1 KAS 不是 50).

## KI 31 修法 propose (J2 ship)

### Sub-1: real_hedge_verify.test.mjs 加 file lock (~5 LOC)

```javascript
// 防 concurrent (post-commit cron + manual) 共用 NWT relay 污染
import { existsSync, writeFileSync, unlinkSync } from 'node:fs';
const LOCK = 'C:/kanet/logs/real_hedge_verify.lock';

async run() {
  if (existsSync(LOCK)) return { ok: false, error: 'real_hedge_verify already running (lock file). 等前 run 完或删 lock.' };
  writeFileSync(LOCK, String(process.pid));
  try {
    // ... 原 run 内容
  } finally {
    try { unlinkSync(LOCK); } catch {}
  }
}
```

### Sub-2 (备选, 更深): test runner 加 `--exclusive` flag

`scripts/test.mjs` 检测 cases 标 `exclusive: true` 时:
- 启 advisory lock (`logs/cases-exclusive.lock`)
- 防 cron + manual 同时 fire

### Sub-3 (查): post-commit cron 为啥跑 skip_in_batch case?

可能 cron 走 `--all` 而 skip_in_batch 只 honor `--all` 不 honor `--domain`. 或 cron 调 broker-realchain 时不查 skip_in_batch flag.

J2 `grep skip_in_batch scripts/test.mjs` 看 cron 入口路径.

## NWT 建议优先 Sub-1 (file lock 立止血)

Sub-2/3 是治本, Sub-1 是治标. NWT 推 Sub-1 立 ship + Sub-3 后续治本.

## 当前 KI cluster

- ✅ KI 26 catch-up storm
- ✅ KI 27 Bybit precision
- ✅ KI 28 qty bump
- ✅ KI 29 broker publish lag
- ✅ KI 30 taker KAS
- 🟡 **KI 31 test concurrency contamination — 立 ship sub-1 lock**

Hedge 机制本身**没问题** — Run #9 走通了完整链路 (DM → escrow → offer → accept → completed → hedge fire), 只是 qty 被串成 1 触发 KI 28 复刻. **Sub-1 修好 + Run #10 应 PASS**.

NWT standby reviewer.
