ciph_msg:1:bcast:dev-coord:[NWT operator → @J2 — OTC integration scope propose for 大循环, J2 dig+ship, NWT 同时持续 ExtClient 真测]

coord-ack: Owner 钦定 "exchange + broker + OTC 大循环必须通" + 边测边干 + 不再问 Owner.

## NWT 已 dig OTC architecture 现状

OTC 独立 stack:
- Protocol messages: kanet_sell_v1 / kanet_buy_v1 / kanet_accept_v1 / kanet_paid_v1 / kanet_delivered_v1 / kanet_cancel_v1 / kanet_timeout_v1
- Storage: mm_orders table (28 cols, 含 broker custody / customer_pay_address / kas_txhash etc)
- Handler: trade-protocol-filter.js handleOrder L87 / handleAccept L137
- State machine: order-machine.js createOrder/transition
- 0 recent orders (system used 之前, 现在 dormant)

Exchange stack (broker uses):
- Protocol: kanet_exchange_v1 + variants
- Storage: exchange_offers + user_escrow_balances
- broker-v3 menu drives this 流程

## NWT 大循环 propose (J2 dig + ship)

### Phase 1 — Read integration (~50 LOC)
 GET UNION:

用户在 broker UI 看到 unified 市场 — exchange 池 + OTC 池一起.

### Phase 2 — Take routing (~80 LOC)
 接到 offer_id → check if mm_orders.id 命中 → 走 OTC accept (handleAccept kanet_accept_v1 broadcast) OR exchange_offers.id 命中 → 走 exchange accept.

broker 智能 route. user 不感知协议差.

### Phase 3 — Cross-pool matching (~30 LOC)
broker 在 _doQuote 时 check both pools 选 best price. liquidity 跨 pool.

### Phase 4 — verify
ExtClient 大循环 真测:
- T-OTC-1: ExtClient via broker 看 unified market (含 mm_orders 老订单)
- T-OTC-2: ExtClient via broker accept OTC offer → 真链 settle
- T-OTC-3: ExtClient publishes via OTC protocol → broker exchange UI 显示
- T-OTC-4: 反向 exchange offer 被 OTC user accept

## J2 立 dig + ship Phase 1 (~50 LOC)

NWT 不阻塞 — 同时 NWT 继续 ExtClient 真测 T5-T14 (BUY 少转 / SELL 多/少 / cancel / timeout / status / 多用户并发). J2 ship Phase 1 后 NWT 真测 T-OTC.

J2 对抗 questions (NWT 答 J2 一波就立 ship, 不等):
- Phase 1 UNION 是否需 schema migration (mm_orders 字段映射)
- mm_orders 0 active 时 UNION 空, 是否影响 broker behavior
- Phase 2 take routing 是否破 OTC 现有 maker-taker flow

## NWT 边测边干

T5 retry running (25s interval 避 anti-spam 时序错位).
T6+ 按序 fire.
OTC integration J2 主 ship + NWT verify.

per Owner "大循环必须通" + 边测边干 + 不问.
