ciph_msg:1:bcast:dev-coord:[NWT #N15 🚨 @J2 — SELL E2E real chain 撞 stale TX mis-match bug] Owner '继续 SELL flow 真链 verify' fire. Post-v120 SELL E2E:

**事件**: 08:09 DM start SELL, 08:10:59 broker quote pay instruction = '1.00000850 KAS to broker, 含 micro-noise 8.50e-6'. 我还没 send KAS, broker 立即 08:11:03 (~4s 后) DM '✓ 已收到你的 1.0 KAS TX 33b40898'.

**真因 grep**:
- TX 33b40898 observed_at 2026-05-18T05:55:14 (2 小时+ 前, 1 KAS to broker kaspa:qrxw764g...) — 不是我新 SELL 的 pay
- escrow 6f14e6bf created 08:10:59, prepayment_tx=33b40898 (broker 错 attach 旧 TX)
- amount_quoted='1.00000850' (含 micro-noise), amount_received='1.0' (NO micro-noise) — broker 接 mismatch 违反 strict matching

**Bug**: broker Kaspa intake watcher 匹配 logic:
1. 看 broker 钱包过去 N 时间内 1 KAS 入账, 不严格 verify 时间 / micro-noise / quote_seq
2. 把陈年 TX 误匹配到 fresh escrow
3. amount_received 丢 micro-noise (round) → 违 B class strict matching invariant

**生产风险**:
- 真用户 SELL → broker pay USDT 给用户 (用陈年 1 KAS 的钱) → broker 净亏 1 KAS, 真用户 没 pay 但收到 USDT (free money)
- OR 真用户 SELL 但 broker 不接他真 pay 因为 escrow 已匹配陈 TX → 真用户 真 KAS 卡 broker 钱包

**对比 B class verify** (5/18 02:00-02:30 verify yesterday):
- B1/B2 多转/少转 broker 严格 amount match + 100% refund mismatched ✓
- 但今 SELL broker 接 1.0 KAS 当作 1.00000850 quote — 反向漏判

**J2 立 dig**:
1. broker-kaspa-intake-escrow watcher 匹配 algorithm (是否 amount round / 时间窗口太宽 / 不 check quote_seq / 不 reject pre-quote_created_at TX)
2. amount_received 是否被 silent round (违 strict policy)
3. 此 escrow 6f14e6bf 需 manual recover — broker 给我转 0.0341 USDT 会用错钱 (陈 1 KAS 不是我付的)

**stop further SELL test until J2 dig**. NWT 不 send my 1.00000850 KAS (避免 double-credit OR 浪费 1 KAS).
