ciph_msg:1:bcast:dev-coord:[NWT T-NWT-05 DONE] · B 模式代卖 publish + expired refund · smoke 38/38 · commit 401405a1

## 验收 4 条 (J1 22:16 给的)

### 1. ✓ 0 ccxt / 0 mm-otc / 0 trade-executor — 红线守住
`grep -E 'ccxt|mm-otc|trade-executor|trade_executor' kasia-console/src/services/broker-intake-watcher.js` → 0 命中

### 2. ✓ smoke 4 case 全绿 (38/38 PASS, 0 fail)

```
Case 1 · 主路 sell_kas → publish 成功         17/17 PASS
Case 2 · publish 失败 → sendKas 退 + DM        7/7 PASS
Case 3 · _scanExpiredBrokerOffers expired → sendKas + chain_event 标记 + 幂等  8/8 PASS
Case 4 · 无 pay_address → DM await_pay_addr   6/6 PASS
```

关键 assertion 验证:
- Case 1 `accepted_chains[0].address = PEER pay (NON-MAKER, Q1 design)` ✓ 真非托管设计落地证明
- Case 1 `give_amount=49.9 (50 - 0.1 fee)` ✓ v2.1 §6 fee 模型
- Case 3 `second scan handles 0 (idempotent via chain_event marker)` ✓ broker_kas_refunded 防重发
- Case 4 `publishOffer NOT called + no sendKas` ✓ 等 J2 T-J2-10 兼带, 不混路径

### 3. ✓ commit + bundle
- commit `401405a1` `feat(broker): Phase 4 B mode exchange-protocol publish (T-NWT-05)`
- 2 files: kasia-console/src/services/broker-intake-watcher.js (+147/-3) + scripts/smoke-broker-sell-publish.mjs (新 ~250 LOC)
- bundle: http://192.168.1.123:9202/bundle (26621 bytes, c360b146..401405a1, 含 J2 a977e28b/92ac0196/96950ee3/39e047bb 同步过)
- 拉法: `curl -o j2.bundle http://192.168.1.123:9202/bundle && git fetch j2.bundle master:nwt-t05 && git cherry-pick 401405a1`

### 4. ✓ dev-coord 贴 (本条)

## 实施摘要

**主路** (broker-intake-watcher.js sell_kas 一致分支替换):
1. `_getUserPayAddress(peer)` — retail_dex_user_memory 优先, retail_dex_orders fallback
2. fee + price 校验 (DEFAULT 0.1 KAS / fetchKasPrice)
3. `_publishOffer(...)` POST `/api/exchange/publish` (publish endpoint 内自动 fund-lock + 2x broadcast retry)
4. publish 失败 → 立即 sendKas 退原 + DM (Q2 b 保险)
5. publish 成功 → DM 用户报价 + offer.id + broadcast tx

**Sub-tick** (Q3 a, 5 min interval):
- `_scanExpiredBrokerOffers()` 扫 maker=Trader-B + protocol_status IN ('expired','cancelled','timed_out') + metadata.source='broker-intake' + 未 refunded
- sendKas 退原 intent_qty + INSERT chain_event 'broker_kas_refunded' 防重 + DM 通知

**触发依赖** (J1 22:16 verify):
- exchange-machine.expireStale() (line 452) 周期把过期 offer 标 'expired' (Console 自带 worker)
- 我 5 min sub-tick 5 min 内捕获 → refund. 协议层 + Console 层各司其职.

## 端到端待验 (J1 留 J2/Owner 真测)
smoke 是行为级, 没真打 verifier. 真 publish → autoTaker 真接 → cross-chain verifier 真 verify USDT 直付 user pay → exchange-machine handleExchangeDelivered → broker auto-deliver KAS → user 实收, 这条全链路靠 J2 端到端 + Owner Kasia 手验.

## 红线遵守
- ✓ 不自建状态机 (走 exchange-machine.transition)
- ✓ 不自建订单表 (走 exchange_offers 唯一真相源)
- ✓ NO TX NO STATE (publish 失败立即 sendKas, broker 不持仓; expired refund 写 chain_event 才推 state)
- ✓ broker_fee_kas 从 KAS 扣 (give_amount=amount-fee, USDT 数字干净)
- ✓ 三重透明 (Agent Card service_terms 上链 [T-NWT-04 已做] + DM 明示 fee/接单链/广播 tx + chain_events broker_intake_processed/broker_kas_refunded log)
- ✓ broker 0 中转 USDT (verification_meta.accepted_chains = user 地址)

## Phase 4 战役收口
- T-NWT-04 ✓ Agent Card service_terms 上链 (124c61e0)
- T-NWT-05 ✓ 本条 B 模式代卖 publish + 退款
- T-J2-08 ✓ A 模式撮合 (J2)
- T-J2-09 ✓ BUY 闭环 (J2)
- T-J2-10 ⏳ 12h stale scanner (J2 排队)

J1 cherry-pick 401405a1 后, broker B 模式代卖路径在 J1 master 完整落地. Owner 两个端到端真链路 (买 50 KAS / 卖 50 KAS) 可在 J2/J1 任一节点 Kasia DM 验证.
