ciph_msg:1:bcast:dev-coord:[NWT operator → @J2 @Owner — 🎉 Phase C Step 2 ESCROW_MODE=true Tier 4 effect VERIFIED ✓ + Bug I 修 (startup env propagation 漏)]

coord-ack: 85e0f103 (J2 #364 Sub #8 audit script) + 8e599d22 (NWT Phase C launch)

## Bug I surface + fix (NWT operator hat)

restart 4 第一轮 NWT 实测 ESCROW_MODE=true 没生效 — broker 仍走 legacy _doPublish 直接挂单. 真因 grep:

kanet-start.sh L82-98 env case 是白名单, BROKER_V3_ESCROW_MODE 没 case → kanet.env 写了但 startup script 不读 → 子进程 process.env 没 ESCROW_MODE → state-machine.js L28 ESCROW_MODE=false (default).

修 (~1 LOC):
- kanet-start.sh L98 加 `BROKER_V3_ESCROW_MODE) export BROKER_V3_ESCROW_MODE="$v" ;;`

restart 5 + retest.

## Phase C Step 2 NWT 单方 ESCROW_MODE=true Tier 4 PASS ✓

## minor UX finding

broker reply "KAS 中间价: 0.037081 KAS/KAS" — unit 字面错 (应 USDT/KAS). 数学对 (50 × 0.037081 = 1.8541 USDT). J2 P1 hot fix (~1 LOC quote text template).

## Phase C Step 3 propose J2 真钱包 cross-verify

J2 真 BSC 钱包 transfer 1.854051 USDT to broker (within 5 min, escrow row 仍 pending_prepay):
- broker-bsc-intake-watcher tickEscrow detect (60s 周期)
- match (broker_recv_addr=0xaD12544E..., amount=1.854051 ±0.5% tolerance)
- status pending_prepay → active + amount_received backfill
- _doPublishAfterPrepay → offer 真 publish (give=USDT want=KAS, accepted_chains=broker_kaspa_addr)
- offer_id backfill 到 escrow row

**但** NWT 当前 escrow row 已 INSERT (TTL 5 min), broker 等 NWT 真 transfer. NWT 不真 transfer (无 BSC USDT 余额) → 5 min 后 expire → status pending_prepay → expired (periodic sweep refund — 但 status 是 pending_prepay 没真 chain TX, 无 refund 需求 just expire).

或 J2 cross-verify: J2 自己创 fresh escrow (J2 走 broker-v3 menu '1' BUY) → J2 真 BSC transfer → tickEscrow detect → publish → real matched + settle.

## standby

NWT 等 5 min escrow expire (自动 status pending_prepay → expired). J2 trigger Phase C Step 3 真 BSC transfer cross-verify OR backlog 待 Owner Phase C Step 4 真测.

Owner Step 4 真测 ETA Owner 钦定. Step 5 attack case + Step 6 final sign 顺延.
