ciph_msg:1:bcast:dev-coord:[→ QCLAUDE-NWT] [OPUS→QCLAUDE] [TASK 2.1] [STAGE 2 NON-CUSTODIAL]

首笔 E2E 是托管路径，Owner 定调改非托管。协议底座全 ready：
- exchange-machine.js:578 调 verifier 不传 expectedFrom (sender 不检查)
- exchange-machine.js:634 delivery 读 verification_meta.receive_address 直发第三方
- market-seeder.js:141 Maker 挂单时已在 verification_meta.accepted_chains 放地址

6 步改造，从 2.1 开始。

============
TASK 2.1
============
只改 kasia-console/src/services/retail-dex.js。其他文件一律不动。

### 改 1: computeQuote 重写
现: 查 agent_wallets WHERE relay_node_id=broker 返 Broker 自己的 BSC 地址
改: 从 offer.verification_meta.accepted_chains 读 **Maker 的**地址

新签名: computeQuote(order, offer, brokerRelayId) →
  {ok:true, quoted_usdt, maker_pay_addr, mid_price, offer_id, give_amount}
  | {error, friendly}

关键逻辑:
- offer 由调用方传入 (不再内部查 DB)
- quoted_usdt = offer.want_amount (非托管: 用户直付 Maker ask，不加 spread)
- 解析 offer.verification_meta JSON → accepted_chains 数组
- normalizeChain(order.pay_chain) 后匹配 c.chain (小写对比)
- 匹配 + 有 address → ok; 否则 error='no_maker_addr'
- 废弃 spread / 废弃 getAgentWalletAddr 在此函数的调用

### 改 2: 新函数 selectBestOffer(order) 导出
职责: 按 side=buy_kas + qty + pay_chain 从 exchange_offers 查 open 单选最优价

SQL: WHERE protocol_status='open' AND give_asset='KAS' AND want_asset='USDT'
     AND (give_amount = qty 精确 OR give_amount >= qty fallback)
     AND expires_at IS NULL OR expires_at > now
     ORDER BY want/give ASC LIMIT 1
再 parse verification_meta.accepted_chains 过滤必须含 normalizeChain(pay_chain)
匹配失败返 null (不 throw)。sell_kas 本轮不做。

### 改 3: 删 getSpread 函数整体
调用点只在 computeQuote 里 (本轮一并删)。grep 确认无其他引用。

### 红线 (不碰)
- handleDm / processPaidOrder / processExecutingOrder / processRefundingOrder
- 任何 exchange-machine.js / trade-protocol-filter.js / api/
- agent-mind / migrate / fetchKasPrice import

### 5 关自测 (必跑)
关1 静态: node --check / wc -l 真实行数 / grep 禁入 (agent-mind mind-manager adapter brain) 返空 / exports 列出
关2 DB+逻辑: 写 smoke-2.1.mjs 12 case:
  1-3 合法 bnb/eth/polygon offer → computeQuote ok + maker_pay_addr 对
  4 accepted_chains 空 → error
  5 verification_meta 非法 JSON → error 不 throw
  6 order.pay_chain='BSC' + offer chain='bnb' → 归一匹配
  7 selectBestOffer 精确 qty=10 命中
  8 selectBestOffer fallback qty=10 give_amount=50 命中
  9 无挂单 → null
  10 chain 不匹配 → null
  11 offer 过期 → null
  12 status=matched → null
关3 边界: null/空/错输入全不 throw
关4 回归: handleDm 调用处会编译失败 — **这是预期**，2.2 修。DONE 里明说
关5 独立 smoke: 脚本输出贴 DONE

### DONE 格式 (发 dev-coord 带 [→ OPUS])
```
[→ OPUS] [QCLAUDE] [DONE TASK 2.1]
Files: retail-dex.js (+X -Y net Z)
Del: getSpread
New: selectBestOffer
Mod: computeQuote 签名变

关1 静态 PASS/FAIL
关2 DB PASS/FAIL
关3 边界 PASS/FAIL
关4 回归: handleDm broken 符合预期
关5 smoke 12/12 输出:
[贴真实输出]

git diff --stat:
[贴]
```

铁律:
- 行数必须 git diff --stat 真实值
- smoke 输出必须真跑
- spec 歧义 → [? QUESTION TASK 2.1]
- 禁入 grep 证据贴来
- 不 git commit (我统一 commit)

开工。
