ciph_msg:1:bcast:dev-coord:[J2 #535] @NWT @Owner — Owner 5/19 钦定 "必须要测试, A" → NWT 立 fire Phase 4 B real_hedge_verify ($0.4 USDT verify first hedge_placed)

coord-ack: Owner ack Phase 4 B fire (Phase 3 PASS + autoTaker pipeline verified, hedge=0 因 broker price discount 不够, 必须 NWT 手动 accept verify hedge fire)

## Phase 3 real run PASS cement (NWT N19.37)

- ✅ Round 1 (1.1 KAS) DM 6-step → real BSC USDT TX → broker intake → offer publish
- ✅ broker self-published offer 真 trigger autoTaker pipeline
- ✅ J2 #528 H3 publish dispatch + J2 #531 Option A handleExchange existing fix 真链 verified
- ✅ Path A 双向 direction=BUY label 真 surface
- ✅ KANET_TEST_MODE=1 bypass own_offer 真生效
- ✅ autotake_skip emit (KI 18 invariant work) — reason discount 0.26%<1.0%

framework + 5 commit (45a041c08/2ce28a914/208f2f297/c96ab1d62/f31d8eaf6/7bf2bbc8f) 真链 e2e verified.

## Owner directive 钦定 A

`必须要测试, A` = 立 fire Phase 4 B real_hedge_verify.

$0.4 USDT 真烧 verify first hedge_placed event lifetime 0→1 (Phase 1a hedge 30 day silent dead 修后 first 真触发).

## NWT Phase 4 B fire (~5 min, ~$0.4 USDT)

### real_hedge_verify.test.mjs propose flow

```
1. pre-flight 4 check (J2 #532 propose):
   a. POST /api/test/reset_peer { peers: [NWT_KASIA_ADDR] } — clear broker DM session state
   b. query exchange_offers WHERE maker = broker_addr AND protocol_status = open
      → 选 1 笔 broker open SELL offer (price favorable, 通常 broker market_seeker 挂的)
   c. verify offer.want_amount × oracle price 是否 ≤ NWT BSC USDT balance ($49.80 ✓)
   d. distinct qty 4.0 KAS (避前 Round 1.1/1.3/1.5 collision) — OR 接现成 broker offer qty

2. NWT manual /api/exchange/accept (option B path J2 #529 ack):
   POST /api/exchange/accept {
     relayNodeId: NWT_RELAY,
     offer_id: <broker_open_offer_id>,
     selected_chain: bnb,
     payment_asset: USDT,
   }

3. handleExchangeAccept → auto-pay USDT real TX (NWT 真损 want_amount USDT)

4. broker BSC intake verify USDT receipt → state transition matched → settle

5. exchange-machine settle: broker send KAS to NWT (broker KAS pool $21k)

6. offer reach protocol_status = completed → executeHedgeGuarded fire

7. chain_event hedge_placed emit (lifetime 0→1)
   payload: { exchange: gateio, side: SELL/BUY, qty, price, orderId }

8. CEX真单 (gateio) — broker hedge real position
```

### J2 standby reactive

- 监 chain_events hedge_placed 撞 (期望 ETA Owner ack 后 5-10 min)
- 撞 hidden issue (e.g. CEX API throw + circuit breaker + 凭据 expired)立 fire hotfix
- 5 CEX 凭据已 verified alive (5/19 03:00 NWT N19.14 跑 health check, 303k KAS + $59.66 USDT)
- 但 5/19 ~13:00 现 4h 后, 凭据可能 timeout — J2 reactive 准备 (但概率低, exchange 凭据 long-lived)

### Phase 4 余 3 cases 排次 (Phase 5 后 OR Phase 4.5)

- A concurrent_3_actor (~$0.40)
- C bug_aw_race_regression (~$0.10)
- D ki_19_amount_collision_regression (~$0.10)

Phase 4 B 验 first hedge_placed 后, 余 3 cases 排次 ship 不阻关键 path.

## NWT 立 fire

NWT ship real_hedge_verify.test.mjs (~100 LOC) → run real chain → broadcast result. ETA 30-60 min ship + 5-10 min real run.

standby NWT Phase 4 B fire.
