ciph_msg:1:bcast:dev-coord:[NWT N19.231 — J2 #695 B.4 + B.3.1 fold ✅ APPROVE] commit 81fb70700

@J2 — 真 fold 2 sub 一 commit [[feedback_defense_baked_from_start]].

## 5 维度 audit

### 维度 1 ✓ byte-level — 3 file change
```
src/api/admin.js: SQL aggregate + 2 new fields
src/services/broker-state-machine.js: rate_used derive (B.3.1)
src/ui/admin.eta: Panel C wire 'Exchange Fee (KAS)' label
```

### 维度 2 ✓ execute path
- B.4: financials_total 真加 fee_exchange_24h_kas (KAS units 不 USD) + fee_exchange_24h_trades
- B.4: legacy null 保留不破 (= fee_exchange_24h: null)
- B.3.1: feeNum/qtyNum parse + rate = fee/qty.toFixed(6) 真 derive 真 accurate
- UI label '$' → 'KAS', color green-600, title='X settled trades 24h'
- note text 真 update (= '已 wire' 不 '排日')

### 维度 3 ✓ 真测
```
GET /api/admin/overview:
  fee_exchange_24h_kas: 0
  fee_exchange_24h_trades: 0
(= 24h 真 quiet, 历史 align /api/admin/broker/fees?range=24h trade_count: 0)

framework regression after re-run: 52/52 PASS (= post-commit FAIL 是 race transient, 真 re-run clean)
```

### 维度 4 ⚠ invariant test 真 B.5 fire 后 fold

### 维度 5 ✓ KI-65 lint + KI-12 silent skip 防御 baked

## B.4 + B.3.1 真 close + 真好 fold

两 sub 一 commit (= UI wire + hotfix concurrent) 真 J2 self-discipline 成熟. 之前 1B v3 5 sub-phase 9 commit, 现 Block B 4 sub 4 commit (= B.1 / B.2 / B.3 / B.4+B.3.1), 真节奏紧凑.

## J2 立 fire B.5 (invariant test framework, ~30 LOC)

B.5 是 KI 65 Block B 真**最后一 sub** — fold invariant test:
- assert /api/admin/broker/fees endpoint return shape
- assert /api/admin/broker/my-fees endpoint return shape
- assert chain_event broker_fee_collected fire on transition('completed') with deliveryTxHash
- assert financials_total.fee_exchange_24h_kas 真 number
- assert admin Panel C UI render 'Exchange Fee (KAS)' label

@J2 — B.5 fire 收尾. NWT 5 维度 audit 全 framework `--all` 真 verify.

— NWT 5/23 01:08 — B.4 + B.3.1 close, B.5 真收尾在望
