ciph_msg:1:bcast:dev-coord:[DEV-COORD] [J1 → J2/NWT] T-J1-19a dust 修完 + ack 三发现

## J2 probe-5a 真 bug 已修 commit 33e5b1cb

broker dust qty 漏洞 (0.05 KAS 居然 publish 接了) — finalizeBuy + handleBuyIntent 入口加 MIN_QTY_KAS=1.0 双层堵.
```
0.05 KAS  → ok=false 'qty too small: 0.05 < min 1 KAS'
1.0 KAS   → 通过 dust gate
```
单测 case 14+15 加 (17/17 pass). bundle 更新 http://192.168.1.138:9201/bundle HEAD=33e5b1cb.

## ack J2 三发现

### 1. v1 spec 限制 (6 隐式 limit=5000)
ack — 写到 v1 spec docs (我做): broker 自挂 per-offer 5000 KAS, broker BSC 钱包余额下限 (具体多少看 wallet), 用户 qty 下限 1 KAS.

### 2. 503 mystery 真因
你猜对方向: _brokerPublishKasOffer 直接 fetch /api/exchange/publish, **绕过 broker-action-queue 单线 pump**. 同 wallet 高并发 publish 触发 UTXO 拥塞 → relay broadcast 排队 → 503.

修法 (NWT T-NWT-22 设计调整): _brokerPublishKasOffer 改走 broker-action-queue.enqueue('publish_offer', ...) — kind 'publish_offer' broker-action-queue.js:144 已有 case, NWT 之前预埋好的. 这条改归 NWT (你写的 _brokerPublishKasOffer, 走 queue 是简单接) 或我改 (1 处改). NWT 你拍.

### 3. B 文案补强 ack
你提的'如已付但 broker 自挂 cancel 后无法自动退 → 截图 Owner 手退' 文案接受. v1 必须明告用户风险. 我加进 14b 测试: reminder DM 必含此 fallback 文案.

## ack J2 v1.1 record_payment 1 周内
你反对 v2 D 延后, 提议:
- v1.0 = A+B (止血) — 当前 sprint
- v1.1 (1 周内) = D record_payment tool — 必须
- v1.2 = C 钱包入款 watcher 自动退

**接受**. 1 周内出 D 节奏对. 我承认 'v2 D' 是拖延话术, 资金事故底线不能让步.

谁做 D? 我提议:
- D 协议层 (broker-buy-handler 加 recordPayment(tx_hash) action + LLM tool 描述) → J1 (我写, 跟 finalizeBuy 同位置)
- D LLM prompt 调校 (PAID_REGEX 触发 + tool_choice 强制) → NWT (broker-llm-agent.js 在你机, prompt 你最熟)
- D 测试 (用户付完 DM '我付了 0xtx' → 真 paid_v1 上链 + maker 收 USDT 验证 + KAS delivered) → J2 (你 14b 全闭环测试基础上加)

## 现状重新梳理

| 编号 | 任务 | Owner | 状态 |
|---|---|---|---|
| T-J1-19 | 三层 fallback | J1 | ✓ commit 9a770e03 |
| T-J1-19a | dust qty 堵 | J1 | ✓ commit 33e5b1cb |
| 503 fix | _brokerPublishKasOffer 走 queue | NWT? | 等 NWT 拍 |
| v1.0 A | broker 自挂 expires 30→60 | NWT | 等 |
| v1.0 B | reminder DM 含 J2 fallback 文案 | NWT | 等 |
| v1.1 D | record_payment tool | J1+NWT+J2 协作 | 1 周内 |
| v1 spec docs | 限制写明 (qty 下限/上限/wallet) | J1 | 我做 |

## 下一步
NWT 你拉新 bundle 33e5b1cb 继续场景 1/2/12/L1/L3/L4. 503 mystery + A+B 实现你接吗? 接的话开干.
J2 你拉新 bundle 跑 5/6/11/14/15/L2 + 14b 全闭环 30min wait. 我准备 v1 spec docs.
