## 但 — 1 critical 架构 gap NWT 未 surface

7 services key on getMarketMakerRelayIdOrThrow():

```
broker-treasury-monitor.js:126           — CEX inventory snapshot filter
cex-bridge.js:48                          — CEX bridge route src/dest
hedge-router.js:29, 35                    — hedge order route
marketmaker-inventory-watcher.js:49       — wallet probe
marketmaker-kas-refill.js:27              — refill target address
marketmaker-multichain-rebalance.js:29,90,102 — rebalance multi-chain
```

### post-Sub-1.2 影响 (= migration v143 strip marketmaker from Trader-A/B)

all 7 services 自动 redirect MarketMaker-A — 0 fund relay. 具体:

- **broker-treasury-monitor**: CEX accounts WHERE relay_node_id=MarketMaker-A-id → **0 rows** (MarketMaker-A has 0 exchange_accounts). Trader-B 5 CEX accounts 不再 snapshot. **Block B broker fee / Panel C 失数据源**.
- **cex-bridge / hedge-router**: hedge route to MarketMaker-A → 0 fund → broker incoming USDT 不 hedge. **broker Trader-B 净 USDT pile up, KAS pool deplete**.
- **marketmaker-kas-refill / multichain-rebalance**: 把 KAS refill MarketMaker-A wallet, 不是 broker Trader-B wallet. **broker KAS pool 不 refill** (= 用户撞 'broker insufficient KAS').

### asymmetry 已存在 (= 不是我现 introduce)

```js
// broker-treasury-monitor.js:126 CEX 查询用 mmaId
const mmaId = getMarketMakerRelayIdOrThrow();
const cexAccounts = sqlite.prepare('SELECT * FROM exchange_accounts WHERE relay_node_id = ?').all(mmaId);
// 但 L144 写入 broker_id
for (const s of items) ins.run(getBrokerRelayIdOrThrow(), s.chain, s.asset, ...);
```

设计假设: broker == marketmaker (Block A.5 consolidation). Sub 1.2 strip 会 invalidate 此假设.

## 3 options surface (= 不 self-decide, 必 NWT + Owner ack)

### Option α — Sub 1.2 as r249 written (= strip Trader-A/B marketmaker)

+ 干净分离: marketmaker = MarketMaker-A 唯一
+ Owner thesis '丝滑配合' 真实证: 新 broker swap test 看 MarketMaker-A 真 dispatch
- broker hedge 7 service 全失效 (= MarketMaker-A 0 fund)
- 需 Owner fund MarketMaker-A 才 unblock 7 service (= Sub 3 prerequisite)
- Sub 3 fund 之前 broker 完全 unreplenishable

### Option β — keep dual marketmaker (Trader-B + MarketMaker-A), seeder pick by config

+ broker hedge 7 service 不破 (= Trader-B 仍 marketmaker)
+ MarketMaker-A 渐进 onboard (= 不撞 0-fund cliff)
- seeder dispatch 需 explicit preference (= market_seeder_config 加 preferred_marketmaker_id field, 或 resolver opts.preferOldest=false)
- 多 LOC, seeder 仅 Sub 1.1 refactor

### Option γ — split resolver: hedge services switch to getBrokerRelayIdOrThrow()

+ Sub 1.2 strip 安全 (= hedge 7 service 仍 attach broker pool)
+ MarketMaker-A 真 exclusive marketmaker, 不 conflate
- 7 file 改: broker-treasury-monitor / cex-bridge / hedge-router / marketmaker-inventory-watcher / marketmaker-kas-refill / marketmaker-multichain-rebalance — 改 import + call site
- 语义 cleanup: "marketmaker 库存" 真 broker 库存 (= 把 6 month asymmetry sediment)
- ~30 LOC sweep, semantically 真 cleanup

### J2 倾 Option γ

理由:
1. broker hedge service 真 broker 库存 service (= 看 L144 写入用 brokerId 已 consistent)
2. Block A.5 consolidation 设计 broker==marketmaker 假设破 (= Owner 现 钦定 plug-in capable)
3. ~30 LOC 比 Option β 加 preference field cleaner
4. Sub 3 fund Owner 真有时间 invest MarketMaker-A 跑实际做市 (= 不 force-coupled with broker hedge)

## Sub 1 重 spec propose

### Sub 1.1 market-seeder.js refactor (NWT r249 spec, 不变)
### Sub 1.2 migration v143 strip Trader-A/B marketmaker (NWT r249 spec, 不变)
### Sub 1.3 deprecate market_seeder_config.sell/buy_agent_id (NWT r249 spec, 不变)
### Sub 1.4 [NEW] hedge service resolver swap getMarketMaker→getBroker (Option γ)

```
broker-treasury-monitor.js:126   getMarketMakerRelayIdOrThrow → getBrokerRelayIdOrThrow

**注**: 文件名 'marketmaker-*' 保留 不 rename (= 历史符号, 不破 import chain), 仅 resolver 改.

## standby NWT ack + Owner 钦定 option

~30 min Sub 1.1+1.2+1.3+1.4 ship (~60 LOC). 等 NWT pick option (α/β/γ) + Owner ack 后开干.
