## green-light T3.5 — matcher 反馈 user 每 transition (~40 LOC, KI-17 layer 3 真核心)

per task v1.1 §T3.5 + Owner 5/3 broker 4 stage Stage 4 "订单执行过程和结果及时反馈" 真核心:

### Spec brief

```js
async notifyTransition(offerId, peerAddress, oldState, newState) {
  const messages = {
    'open→matched': '✓ 已匹配 taker, 等付款 (30 分钟内).',
    'matched→verifying': '💰 付款已收到, 验证跨链确认中...',
    'verifying→delivering': '✓ 付款验证通过, 发 KAS 中...',
    'delivering→completed': '🎉 KAS 已发出, 交易完成! 请查询钱包确认收款.',
    'open→timed_out': '⏰ 30 分钟无 taker, 订单已 timeout. 退款已发.',
    'matched→disputed': '⚠ 争议产生, 进入 dispute 流程. 等 resolver.',
  };
  const key = `${oldState}→${newState}`;
  const msg = messages[key];
  if (!msg || !peerAddress || !this._actionExecutor) return;
  return await this._actionExecutor.executeOne({
    target: peerAddress,
    message: this.stripMarkdown(msg),  // T2 ship stripMarkdown reuse
  });
}
```

### 设计 note

T3.2 reactor (path b) Skill-instance per DM trigger — matcher reply 在 reactive cycle execute (NOT independent tick)。 user DM matcher → matcher reactor 看 active offers state → notify transitions since last DM。

T3.5 是 broker 真 ship Stage 4 "结果及时反馈" 真 missing piece — server handlers do heavy lifting (DB UPDATE / sendKas), matcher 真 user-facing 反馈 layer。

### Anti-pattern (per task v1.1 §T3.5)

- ❌ 不 throttle reply (broker user expect immediate feedback)
- ❌ 不 silent skip transition (every state change = 反馈)
- ❌ 不 markdown leak (stripMarkdown apply per KI-18)

### Acceptance

- ✅ matcher 真 reply user 每 transition with appropriate message
- ✅ DB messages 真有 row event_type='text' from Trader-M to peer at each transition timestamp
- ✅ stripMarkdown apply (per KI-18 platform-agnostic)

### LOC: ~40

## J2 next

- ship T3.5 (~40 LOC) + tests + commit 触发器
- NWT reviewer 审

post T3.5:
- T3.6 tests + invariant assertion (~50 LOC)
- T3.7 e2e: NWT DM Trader-M → 完整下单 → 0.5 KAS 真发 → 7/7 acceptance verify → **broker 真 ship milestone**
