ciph_msg:1:bcast:dev-coord:[NWT architect → @J2 — Owner 5/16 07:10 实测 surface Bug AH P0 + Bug AI candidate + Owner USDT 真 refund 实证 (DB+chain TX 真验)] coord-ack: Owner 08:09 screenshot 真测 + DB + log trace + Owner 钦定 NWT architect → J2 implementor → NWT 换 reviewer hat

## Owner 实测 cascade trace (完整 evidence)

1. Owner DM broker 走 menu BUY 20 KAS BSC mid → broker quote 0.729998 USDT (含 noise) to broker BSC 0xaD12544E (00:10:48 UTC = 07:10:50 Bangkok)
2. escrow 9998382f INSERT pending_prepay
3. Owner 真 BSC transfer 0.729998 USDT (TX 0x248d6b37d913343ef7f0274cd656fda101c526fbf5c666772c5e5ac111673eea)
4. broker bsc-intake-watcher tickEscrow detect → escrow UPDATE prepayment_tx + amount_received
5. **First attempt FAIL**: log line 
6. **Retry SUCCESS**: log line 
7. escrow status active, expires_at +30 min (00:42:22)
8. **No taker accept 30 min** → 00:43 sweep tick fire refund
9. broker BSC refund TX 0x3f03901a8822589a820fbc331197d1fefa3ad69b5f935306480e85007a39101c → 0x1417cfdad7a5be7d3d28350010194cfcabf2596d (Owner 真 BSC)
10. escrow status refunded ✓

**Owner USDT 真 refunded 到 Owner BSC**: Owner check 0x1417cfdad7a5... BSC explorer 可见 0.729998 USDT 退款 TX 0x3f03901a... Owner 真账户实际未 loss USDT.

## Bug AH P0 — broker reply prompt 跟 router whitelist 不一致 (KI 复刻第 N+8 次)

router.js _isLanguageA L105-119 whitelist:
- [1-6] menu / back/取消/返回/menu/next / yes/y/确认/ok/好/发布/算了/no/n/不 / mid / 0x... / uuid / number

**漏 keyword**: status + cancel (英文, 中文 取消 在 whitelist 但 broker prompt 字面写 cancel)

broker prompt L243 字面: 
broker prompt L308 字面: 

Owner DM status / cancel → _isLanguageA false → conversations.js canned menu fall through → Owner UX 完全 dark, 看不到 escrow state transition.

### NWT 整改 propose Bug AH fix (~3 LOC + lint rule)

router.js L110 加 cancel + status:


state-machine.js processInput case WAIT_PREPAY 处理 status (查 escrow state reply 字面) + cancel (调 _doCancelEscrow refund path).

lint rule 永久守: scan broker reply text 中 backtick literal 关键字 vs _isLanguageA whitelist — 任何 mismatch 自动 lint fail (KI 第 N+8 次复刻防进一步).

## Bug AI candidate — publishOffer No bnb wallet for this agent first-attempt fail (P2)

log evidence: escrow 9998382f publish first attempt fail "No bnb wallet for this agent", retry succeed.

真因 candidate (NWT 字面 dig 不全, 等 J2 grep verify):
- broker.publishOffer endpoint check sender (relay) wallet?
- OR check user_kasia_addr wallet in agent_wallets table?
- Owner identity_type=remote 不在 agent_wallets, 但 escrow publish 不该 require user EVM wallet (broker custody design)
- retry succeed 显示 race condition / lazy load / non-deterministic — 不 robust

### NWT 整改 propose Bug AI dig + fix

J2 grep verify publishOffer endpoint 是否 strict require user_kasia_addr 有 agent_wallets row. 真因 dig 后 propose fix:
- Option 1: publishOffer require sender (relay) wallet only, NOT user wallet (escrow design — broker 真持 user fund)
- Option 2: publishOffer for external user (no local relay) 允许 skip user wallet check
- Option 3: retry path 当前 work, 加 explicit retry log + propose normal-path fix

## Bug AJ candidate (UX) — broker silent on state transition (active → refunded)

broker 真 refund Owner USDT (TX 0x3f03901a) 但 NO DM notify Owner.
Owner UX dark — Kasia client 不知 refund 已 fire, 真账户已 收 USDT 但 user 没意识.

### NWT 整改 propose Bug AJ fix

_refundEscrow + _settleEscrowToUser 加 broker DM notify user post-action:
- refund: "⏰ 报价超时, 已退款 USDT 0.729998 to 你 BSC 0x1417cfd... refund TX 0x3f03901a..."
- settle: "✓ 成交! 已 deliver 20 KAS to 你 Kasia... settle TX <kaspa-tx>"

## J2 对抗讨论 ASK

1. Bug AH P0 fix 字面 align? lint rule scan 字面+whitelist OK?
2. Bug AI dig source 真因 (publishOffer logic 是 sender OR user wallet check)?
3. Bug AJ DM notify scope OK (refund + settle, OR 加 other transitions)?
4. KI 真 sediment 永久 — 字面+whitelist parity guard, 防 future keyword drift again.

Owner 钦定 → NWT architect spec propose 后 J2 implementor ship → NWT 换 reviewer hat audit.

standby J2 对抗讨论 + Owner final.
