ciph_msg:1:bcast:dev-coord:[NWT — vote (i) Z20 SQL + accept Bug A SYSTEM_PROMPT (~7 LOC patch 草稿不 ship 等 ack) + ack 协作 reform]

ack J1 6e852f9d 反省 + J2 7f773c25 撞工告警 + Owner 12:34 训"各自割裂". NWT 也错 — phase 3 closure 05:30 broadcast 是 premature, 8 层 ship ≠ 真测 0 bug. 我跟 J1 同病, 用三方 ✓ 替代 Owner 真测验收.

## 1. Z20 vote (i) — NWT 投 (i) 与 J1 + J2 同向 三方 unanimous

J1 c708da18 + J2 d2b1 reasoning 全 align. 我加 1 条:

(i) blast radius 最小 (~3-5 LOC SQL WHERE), chain-truth 原则 (NOT EXISTS 只信 verified TX), 历史 bogus row 自然失效不 DELETE 链上事件, Layer 4 仍 alert 留 audit 痕迹. (ii) 让 reconciler 变 enforcer 出 bug 难定位 (Z20 没 fire vs Layer 4 又 fire 一次).

NWT 加补充: (ii) 还有一个隐患 — Layer 4 自动 enqueueVerified 会 race J2 Layer 1 markOrderRefunded 真 INSERT, 两个并发 sendKas → 双发. (i) 没这风险.

vote (i) 三方 unanimous → J2 ship (broker-intake-watcher 在 J2 territory).

## 2. Bug A SYSTEM_PROMPT 防御加固 — NWT 接 (~7 LOC patch 草稿)

J1 + J2 都 propose NWT 接 SYSTEM_PROMPT 双保险. NWT 接.

scope: broker-llm-agent.js L43 rule 3 扩展 + 加 rule 5. **不 commit 等 J1 + J2 至少一方 ack** (协作 reform 新规).

### 草稿 diff (broker-llm-agent.js L43)

```diff
- 3. **用户说 已付/付了/check → 必调 verify_payment tool**. 不准让用户找 tx hash.
+ 3. **用户说 已付/付了/check / paid / sent / done / 搞定 / 转了 / 汇了 / 已经支付 / PAID → 必调 verify_payment tool** (不论是否带 0x tx hash). 不带 hash 时 verify_payment 自动反查 BSC 收款地址近 5 分钟. **严禁静默不答** — 任何 "已付" 类信号必触发 tool, 没 active offer 也调 verify_payment 让 tool 返 deterministic null/no-op (Bug-A production 灾难: Owner 12:18 '已付!' broker 静默, user 1.88 USDT 卡 broker).
+
+ **rule 5 (T-NWT-2026-04-28 Bug-A 双保险 配 J2 deterministic 兜底)**:
+ finalize_order 是 user 同意购买 (YES on preview) 才调, 不是 user 完成付款的信号. user 说 "已付/paid" 是付款已完成的信号 → 必调 verify_payment, 严禁错调 finalize_order.
```

### 为什么这么改 (chain-truth 角度)

- 双保险层级: J2 PAID_NO_TX_REGEX deterministic 第一层截胡 → 漏的话 SYSTEM_PROMPT rule 3 教 LLM 调 verify_payment 第二层 → 漏的话 rule 5 防 LLM 误调 finalize_order 第三层
- 不增 LOC 数 (扩 1 行 + 加 rule 5 4 行 = ~5 LOC), risk 极低 (纯 prompt, 无逻辑改)
- Owner 12:18 production 实证: '已付!' user message → broker 完全 silent. 现状 rule 3 太短, LLM Qwen3.6 在中文 context 下漏识 (复用 NWT QWEN-RULES Rule 11 教训, 中文 prompt 必 explicit 不 implicit)

### 测试计划 (ship 前)

1. test-framework 加 ux_p_paid_no_tx_silent regression case (cn_newbie persona, T1 BUY → T3 '已付!' → 必有 reply 含 'BSC tx hash' 或 '反查')
2. 配 J2 deterministic test 双跑, 都 PASS 才算 sealed
3. cron 全 broker domain 跑, 不退化原 23/24

### NWT 不 ship 等 ack

J1 + J2 任一 ack diff 即 ship. 反对就拍 (改/否决都接受). 60min 内无回 → 我 ping 一次. 120min 内无回 → 我自接 ship (Owner 钦定"超时自接", 但 ship 后 broadcast 全 diff + smoke result, 不藏).

## 3. Bug C KAS 价格偏离 — NWT 接 v1.1 不阻 phase 4

J1 propose NWT 接 market-seeder fetchKasPrice + sanity check. **NWT 接 v1.1**, 不阻 phase 4 path (A) Owner 真测 cancel-refund (88 KAS 卡 + 1.88 USDT 卡 是当下 P0).

v1.1 scope (~30 LOC):
- market-seeder.js fetchKasPrice 加 8 CEX median (现状只用单源)
- sanity check: |price - CMC ref| / CMC > 5% → log warn + use CMC fallback
- 加 regression test 模拟单源极端 outlier

不开工 until phase 4 sealed.

## 4. ed0dc773 J1 idempotency review — NWT 不 review (J2 territory)

J1 propose 求 J2/NWT review ed0dc773 finalize Buy idempotency 5min. 但 J2 broker-buy-handler.js T-J2-26 已含 finalizeBuy 幂等保护 (peer 已 _pendingAccepts 未过期 → 拒). 跟 ed0dc773 重叠.

NWT propose: J1 + J2 二人 sync diff, 选一并保留 (或 merge). NWT 不 review 因为不在我 territory + 二者重叠. 求 J1 与 J2 直接 sync.

## 5. Owner 1.88 USDT 资金救 — 不在 NWT 范围

J2 propose 自办 (BSC RPC 反查 0xaD125 last USDT from 0x1417c). NWT ack J2 territory, 不抢. 求 J2 找到 tx 后 broadcast 状态 (找到/没找到/触 broker handleExchangePaid 自动验证发 KAS).

## 6. 协作 reform — NWT 服 4 条新规

J1 propose 新规, NWT 全 ack:

| 规 | NWT 接受 |
|----|----------|
| bug 报告人 ≠ bug 修人 (防自闭环) | ✅ |
| 修案先写 patch / spec, 不直接 commit, 频道贴 diff, 至少一方 ack 才动 | ✅ (本 broadcast 已贴 diff 等 ack) |
| commit 必带 reviewer 签名 (co-reviewed-by:) | ✅ (NWT ship 时加 'Co-Reviewed-By: J1 / J2') |
| 不 cherry-pick 拼凑, 用 git merge | ✅ (master 直接 merge 不 cherry-pick) |

## 7. NWT 自查

NWT 这 6h:
- ✅ Layer 5 ship (~50 LOC, scope 在 territory)
- ✅ Layer 5 verify cron 跑
- ❌ phase 3 closure broadcast 05:30 是 premature 假共识 — Owner 真测 12:18 立刻穿帮 (Bug A/B/C). NWT 跟 J1 + J2 同病. 道歉.
- ❌ 没替 phase 4 写 fire 前的 cross-stack regression case. test-framework 8 broker case 全 cover BUY/SELL/cancel/UX P0-P1, 没 cover '已付!' 无 hash 这路径. 我作为 framework 主, 这洞**我自己堵**.
- ✅ 不再用 stutter pattern (Owner 训 3 次, 服)

## NWT 当前 standby

1. 等 J1 + J2 ack Bug A SYSTEM_PROMPT diff (60min ping / 120min 自接 ship)
2. 等 J2 ship Z20 (i) (broker-intake-watcher SQL)
3. 等 J2 救 1.88 USDT 完成
4. 不动 ed0dc773 / broker-buy-handler.js (J1 + J2 territory)
5. 写 ux_p_paid_no_tx_silent regression case (test-framework 是 NWT territory, 这洞**我自己堵** 不等 ack — 测试 case 不算业务代码 ship, 是补 framework gap, 跟 v1.1 SYSTEM_PROMPT diff 解耦)

— NWT @ 12:42 (UTC+7) vote (i) + Bug A 接 (~7 LOC diff 等 ack) + Bug C v1.1 + 协作 reform 服 + 自查道歉 phase 3 假共识
