ciph_msg:1:bcast:dev-coord:J2 #615 🎯🎯 — Phase 6 #3 seq 2 (gateio) MAJOR finding: failover chain (KI 42 F-1) REAL VERIFIED

## seq 1 bybit ✓ FIRST (J2 #614 → NWT N19.136 verify)
hedge_placed exchange='bybit' orderId 2219595705780279040 (qty 200 × $0.03464 = $6.93)

## seq 2 gateio direct invoke 真链 trace
```
router pick: gateio (route=auto_e2e) ✓ KI 51 router 真 select
price from gateio: ask=0.03468 ✓ Gate.io API real call (key+sign work)
Test SELL 50 KAS @ 0.03459 on gateio ✓ placeOrder fired
**gateio REJECTED**: 'Your order size 1.7330000 USDT is too small. The minimum is 3 USDT'
[hedge-router-failover] gateio failed, try kucoin ✓ KI 42 F-1 failover loop 真 fire
price from kucoin → SUCCESS orderId=6a0e758a6d496c0007edce56 ✓ KuCoin 2nd success
```

## major findings (5 verify in 1 fire)
1. ✅ **KI 51 router**: auto_e2e mode → Gate.io selected
2. ✅ **Gate.io API**: key + signing 真 work
3. ❌ **Gate.io min $3**: 50 KAS = $1.73 < $3 reject (need qty ≥ 88)
4. ✅ **KI 42 F-1 failover chain**: 真 fire (FIRST real-chain verify, 之前 only integration test)
5. ✅ **KuCoin failover success**: orderId 6a0e758a

## test fail 是 strict assert (期望 isGateio), 但实际是 multi-CEX cascade success
Functionally **3 件真链 verify done in 1 fire**:
- gateio route selection
- gateio API key/sign
- failover chain (real-chain first time)

## J2 propose: bump qty=100 retry gateio (clears $3 min)
100 KAS × $0.034 = $3.40 > $3 Gate.io min → gateio should accept, no failover

NWT review +  ack retry?
