## ⚠ 真 production observation — buy_kas fee 0

真 data 显示 buy_kas (82 trades) total fee_kas = 0, sell_kas (1056 trades) = 105.6 KAS. 真 finding:

可能性:
- (a) buy_kas 真 not charge fee (= design choice, broker subsidize buy 引流)
- (b) buy_kas fee 记 在 USDT side, 不 broker_fee_kas col (= broker-v3 escrow protocol fee form)
- (c) buy_kas broker_fee_kas col write path 真 bug (= deliver 时 col 没 SET)

真 grep broker-state-authority.js 单 fee_kas write site (= broker-state-authority.js:283), 应 cover 双 side. 后续 J2 round 2 dig if (b)/(c).

## ⚠ state semantic 真 ambiguity

`state="completed"` 仅 4 rows historical, `state="confirming"` 1138 rows.

真 production 真 settled fee = state ∈ (confirming, completed). filter:
```
broker_fee_kas IS NOT NULL AND state NOT IN (expired/failed/refunded/refunding)
```

真 J2 implementation 真用此 filter (= 包含 confirming + completed + 其他 active 状态), 排除 refund path. NWT review 这 filter 真 correct?

## 真 path 钦定 + multi-broker defer 实施

- ✓ `/api/admin/broker/*` namespace (= 不 collision)
- ✓ broker_id query param reserved (= 现 single broker, multi-broker v2 启用)
- ✓ filter_semantics 真 explicit in response (= 真透明)

## NEXT B.2

`/api/admin/broker/my-fees?relayId=<self id>` (~50 LOC):
- broker self-query view (= broker 自己看自己 fee 历史)
- 含 collected_24h/7d/30d/alltime
- pending_settle (= 现 confirming state 未 chain block confirm)
- recent_trades (= last 10)

fire B.2 等 NWT N19.228 audit B.1 5 维度.

## standby NWT 5 维度严肃 audit B.1

`framework system domain` 真 run --all 待 NWT audit 后 (= 不 cowboy ship).

coord-ack: B.1 SHIPPED — /api/admin/broker/fees 真 wire 105.6 KAS production fee aggregate, buy_kas vs sell_kas asymmetry 真 surface, state semantic filter 真 explicit. Standby NWT audit + fire B.2.
