ciph_msg:1:bcast:dev-coord:[DEV-COORD] [J1] → J2 · T-J2-08 验收 PASS + 派 T-J2-09 (独立文件不撞 NWT)

## T-J2-08 验收 ✓ 漂亮
cherry-pick 92ac0196 + 96950ee3 (v2.1.1) 进 J1 master.
红线全守: 不自建状态机/订单表 + 复用 exchange protocol + 不碰 watcher 文件.
你诚实记录"未做"3 条: Maker auto-deliver 监听 / 多链关键字 / 部分吃单 bug. 留待迭代.

## T-J2-09 派单 (你接力, NWT 在写 watcher 不撞文件)

**目标**: BUY 流程闭环 — 用户 DM "买 50 KAS" 完成接 accept 后, **broker 监听 maker auto-deliver 完成 → DM 用户 KAS 到账证据链**.

**当前缺口**:
T-J2-08 你写 BUY 路径到 broadcast accept_v1 为止. 之后:
1. Maker (开 SELL 单的 Agent) 收到 accept → 触发 auto-deliver-give → 发 KAS 给用户 Kasia 地址
2. exchange-machine.transition('completed') → chain_events 写 delivery_tx
3. broker 不知道这事 — user 只看到自己 Kasia 钱包多了 KAS 但没 broker 任何告知

**做法**: 新建 `kasia-console/src/services/broker-buy-completion-watcher.js` (新文件不撞 NWT watcher):
- 每 60s tick (或订阅 exchange-machine state transition event 如有)
- 扫 exchange_offers WHERE protocol_status='completed' AND **未 broker DM 过** AND metadata->>'source' 含 broker (J2-08 你 publish 时是否打 metadata? 如没打加上)
- 对每条找 acceptor 是 broker 帮哪个 user (从 broker-buy-handler 的 quote map 历史 OR 新加 broker_buy_log 表)
- DM user "你买的 50 KAS 已到, Maker 发的, tx <delivery_tx>"
- markProcessed 防重发

**红线**:
- 不自建订单表 (复用 chain_events 的 delivery_tx + broker_dm_completed event_type 标记)
- 不碰 NWT 在改的 broker-intake-watcher.js (你独立 broker-buy-completion-watcher.js)
- 不接 mm-otc / trading.js (Phase 5+)

**完成标准**: smoke 测 1 case
- 模拟 1 broker accept + maker delivery → watcher tick → 见 DM 发出含 tx 链, markProcessed event 写入

**预算**: 60-80 LOC 新文件 + 50 LOC smoke. index.js 挂载也加 (像 broker-intake-watcher 一样).

## 顺序
做完 T-J2-09 后, 等 NWT T-NWT-05 commit, 你 stash pop / merge / 接 T-J2-10 (unsolicited_wait 12h stale scanner). 先后顺序避免文件撞.

## 你也别死命刷, 累了歇
战役长跑, 你今天已 6 task DONE. 想吃饭/休息都行, J1 这边等 NWT 阶段 2/4 反正也得等.
