ciph_msg:1:bcast:dev-coord:[NWT operator → @J2 @Owner — 🚨 batch 2 真测 2 新 bug surface + AT-05 真测部分 PASS] coord-ack: f0cc0ecb (NWT 13:07 SELL milestone) + Owner 13:15 "继续 不留死角".

## Bug W surface (P0) — broker-intake-watcher 无 orphan TX handling

NWT 真测 AT-05: NWT transfer 50 KAS to broker Kasia 不通过 menu, TX 8a374ec016f8165f.

broker kaspa-watcher tickEscrow query SELECT * FROM user_escrow_balances WHERE status=pending_prepay AND side=sell_kas AND broker_recv_addr=? AND amount tolerance match.

50 KAS inflow 没 match 任何 pending_prepay quote → watcher silently 跳过. **no orphan row INSERT, no 24hr auto-refund triggered**. v6 plan AT-05 spec "24 hr auto-refund" 但 code 实施漏.

broker wallet 真 +50 KAS = 累积无主资金, user (NWT) 无 path 取回 (除 Owner manual sendKas back).

impact: 任何 third-party send KAS 到 broker Kasia (e.g. 误转 / 攻击者 spam) 都成 broker 无主收入. broker custody design 完整性破.

### propose J2 ship orphan handling (~80 LOC)

1. broker-intake-watcher tickEscrow extension: scan recent Kaspa inflow tx (last 30 min from chain explorer OR broker_action_queue), 排除 已 matched pending_prepay TX, 不匹配的 INSERT orphan row (status=orphan, user_refund_addr=sender, amount_received=value, prepayment_tx=TX hash).
2. periodic sweep extension: status=orphan AND created_at < datetime(now, -24 hours) → trigger refund to user_refund_addr (sendKas back).
3. 同款 broker-bsc-intake-watcher 镜像 BSC USDT orphan (BSC 比 Kaspa easier — event.from extractable).

## Bug X surface (P2) — custody-pool endpoint double-count

endpoint /api/exchange/custody-pool L648 字面:
total: kaspaBalance + kasLocks + (kasEscrow?.total || 0)

broker chain wallet 21395.646 字面 includes 4500 KAS (NWT escrow active prepayment). endpoint 加 wallet + escrow_active = **25895 double-count** (escrow KAS 已 stored in broker chain wallet).

真 broker pool 应 reflect:
- broker self-owned KAS = wallet - escrow_active - fund_locks (escrow + locks 是 custody 不 broker assets)
- 现 displayed total 不 align broker self-owned, Owner invariant 比较真 deceiving

### propose J2 ship endpoint fix (~10 LOC)

endpoint return:
- broker_self_owned: wallet - escrow_active - fund_locks
- escrow_active: 4500 (custody balance, 不算 broker)
- fund_locks: 0
- wallet_total: 21395 (chain balance for reference)
- alarm/delta 比 broker_self_owned vs baseline

## AT-05 真测 partial PASS

- ✓ NWT 真发 50 KAS to broker not via menu (Kaspa TX 8a374ec016f8165f)
- ✓ broker watcher 真 detect inflow (broker wallet +50 KAS reflect)
- ✗ orphan row INSERT 不存在 (Bug W code 实施漏)
- ✗ 24hr auto-refund 没 fire (Bug W same)
- spec PASS criteria 字面 fail, NWT 真测 surface 真 issue

## HP-09 SELL 仍在进度

escrow 1d448a18 active, offer 0e709f43 open, expires 13:36:27. NWT 等 sweep 4500 KAS auto-refund verify (Bug J 大 amount + Bug W candidate 同时 fix verify).

## NWT 继续 batch 3 case (不 silent)
