## HP-09 真链测试 sequence

| step | NWT send TX | input | broker reply 字面 |
|---|---|---|---|
| menu | ded15a1995e784e6 | menu | 首屏 banner 含 KAS 现价 |
| BUY | 3ed54301688b7848 | 1 | 已选支付链 1-6 |
| BSC | 9462d58431511f24 | 1 | 已选 BSC, 数量 1-5000? |
| qty 4500 | a2404a423bb814c7 | 4500 | 4500 KAS, 出价? mid OR 自定 |
| mid | 36ceb37cdffe8317 | mid | preview 含 0.036441 USDT/KAS, 总 163.9845 USDT |
| YES | 8449676d28e3b5cc | YES | **报价 163.984507 USDT (含 noise) 到 0xaD12544E broker BSC, 5 min TTL** |

## broker pool 承受分析 (NWT 实测发现)

NWT 之前假设: broker pool 1847 KAS, 单笔 4500 > pool = broker 不能 deliver, 应 publish 时拒 OR queue. 

**真实分析**: 
- BUY flow: broker 收 user USDT 进 BSC pool (+163.984) → 等 taker 真 deliver 4500 KAS 到 broker Kaspa → broker forward to user Kasia + broker pay taker USDT (-163.984)
- broker net KAS Δ=0 (taker 真 deliver), USDT Δ=0 (user prepay → taker)
- pool 承受真实点: 仅 SELL flow (broker 真发 KAS to taker, 需 pool 够)

HP-09 BUY 大额 ≠ pool 烧穿 vector. SELL 4500 才是真 stress (broker pool 1847 < 4500 fail). NWT 5.76 KAS 不够 prepay 4500 KAS SELL, **HP-09-SELL** 移 backlog 等 Owner/J2 真测.

## 现状 NWT v5 v6 case 进度

v6 已 PASS Tier 4:
- HP-05 cancel pre-prepay sweep refund
- HP-09 BUY 4500 大额 (broker pool BUY 不撞)
- UX-01/04/05 + IN-01/02 + AT-04/08 + RE-J (从 v5)

NWT 下 case: HP-10 最小 1 KAS edge + AT-NEW-1 dust attack + IN-03 stress 10 trades.
