## ❌ Critical 1: B1 PAID detect 漏的 cases → LLM hallucinate 不 verify 实付
代码 L73-100 路径:
```
if (hasPublished) {
if (STATUS_QUERY_REGEX.test) return status
if (side='buy_kas' && state IN) {
if (PAID_REGEX || PAID_NO_TX_REGEX hit) → verifyPaymentForPeer
}
// ↓ B1 漏的 cases 落 LLM render
reply = await llm.render(...)
}
```
PAID_REGEX 严: `/(?:已付|付了|我付|paid|pay)[\s\S]{0,40}?\b(0x[a-fA-F0-9]{64})\b/i` — 必含 64-hex tx hash.
PAID_NO_TX_REGEX 严: `/^(?:已付|付了|...)\s*(?:了)?\s*[!？.…]*\s*$/i` — 短 acknowledge 仅.
漏的真用户 PAID 表达:
- "我刚才转了 5 USDT 过去" (无 'paid'/'付' keyword)
- "钱已经到 broker 钱包了" (无 keyword + 含间接表达)
- "我付款完成了, 等等收到" (PAID_NO_TX 不严 — '付款完成了' 含尾巴 '等等收到' 不 match line-end `$`)
漏的 case → LLM render → broker-v2/llm.js SYSTEM_PROMPT 仅教 '严禁编造 fake price/addr/tx hash' 一条, 没教 'paid 信号必调 tool 验证'. LLM 看 user '我付款完成了' state='awaiting_payment' → LLM 可能 hallucinate '✓ 已确认' OR '我帮你查一下' (无 tool 调).
后果: user 真没付 → LLM 假确认 → broker 触发后续 deliver KAS → broker 资金损失. OR user 真付了 → LLM 不 verify → user 卡.
修法: B1 LLM render 前加 fallback — 如 hasPublished + side='buy_kas' + state='awaiting_payment' + LLM 漏 reach (不 PAID hit), 加 SYSTEM_PROMPT addendum '用户可能在说付款, 请仅回 "麻烦发 tx hash 0x..." 不 hallucinate 已确认'. OR 把 PAID 检测 LLM tool 化 (J2 territory follow up).
## ⚠ Medium 1: D1 SQL UPDATE 漏 active row guard
代码 L93:
```sql
UPDATE retail_dex_orders SET state='paid'
WHERE user_kasia_address=? AND side='buy_kas' AND state='awaiting_payment'
```
production grep evidence: retail_dex_orders awaiting_payment=223 rows total. 1 user 多 BUY 历史 row 都在 'awaiting_payment'.
如同 user 之前 100 笔 BUY 卡 'awaiting_payment' (历史 expired 但 state 没 advance — D2 之前没 wire), UPDATE 会 **advance 所有 100 笔为 'paid'** 不仅当前.
修法: 加 `AND created_at > datetime('now', '-2 hours')` 时间窗 OR `AND id = ?` specific row link.
## ⚠ Medium 2: PAID_REGEX 含 tx hash 但 verifyPaymentForPeer 不用 hash 精确查
PAID_REGEX 提取 capture group (0x{64}) tx hash, 但 J2 B1 wire 没 pass 给 verifyPaymentForPeer:
```js
const result = await verifyPaymentForPeer({ peer, chain: activeOrder.pay_chain });
```
verifyPaymentForPeer 内部 scanRecentTransfers 仅 75min 窗 amount match. 浪费 user 给的 tx hash 精确信息.
如 tx 时间窗 > 75min (e.g. user 早 3h 付了, 现在才说 'paid'), scanner 漏 → result.ok=false 'no_match'. 实际 user 给了 hash, 应直接 lookup.
修法: B1 提取 tx hash + 调时 pass tx_hash. verifyPaymentForPeer 加 tx_hash 优先 lookup path (现有 lazy scan 只是 fallback).
## ⚠ Medium 3: 没 rate limit, user spam 'paid' 资源攻击可能
user 'paid 0x1' / 'paid 0x2' / ... 多 msg 不同 content (R34 5s dedup 不命中) → broker 每次 scan_chain (BSC RPC 1-3s latency × spam = 资源消耗 + RPC quota).
修法: B1 加 5min cool-down (per peer) per verifyPaymentForPeer 调 OR 复用 R34 type-based dedup ('payment_verify' kind).
## ⚠ Minor: 没 test case + catch err 没 chain_events audit
(no need block)
## NWT 重审 verdict: ⚠ 1 Critical + 3 Medium (前 ✅ pass 撤回)
J2 push back / fix:
- Critical 1: 修 LLM SYSTEM_PROMPT addendum + LLM tool 化 PAID 检测 OR B1 catch all 'awaiting_payment' state user msg → fallback '麻烦发 tx hash'
- Medium 1: D1 SQL 加 created_at 时间窗
- Medium 2: PAID_REGEX tx hash 提取 + pass verifyPaymentForPeer
- Medium 3: rate limit cool-down
求 J2 r7 push back / fix / commit 后续 patch.
