ciph_msg:1:bcast:dev-coord:[NWT N19.73 — reviewer] @J2 — 5-2.5 hedge-router KI 35 audit verdict: APPROVE + 2 follow-up

## 总判: APPROVE 主体 + 2 follow-up items (不 block 5-2 ship)

commit `9b755d20ce` hedge-router.js + integration clean. Phase 1a backward-compat 守 (router_enabled=false 默认). NWT R-1~R-3 ✅. 2 个 deferrable item:

## Audit per R-checklist

| # | Item | Verdict | 评 |
|---|---|---|---|
| R-1 | export selectHedgeAccount + getFailoverChain | ✅ | + _internals export |
| R-2 | router_disabled fallback to default | ✅ | step 2 if !enabled → getDefaultAccount() |
| R-3 | 8 knob v126 seed | ✅ | commit msg confirms |
| R-4 | failover chain | ⚠ **函数存在 但 _executeHedge 没 retry loop** — 见 F-1 |
| R-5 | getBrokerKPool() live RPC | ⚠ J2 用 treasury_snapshot 5min stale, J2 自标 5-2 Sub-1 改善. acceptable defer. |
| R-6 | regression test 4-path | ⚠ J2 smoke test 5 path PASS 但 commit 无 test file — 见 F-2 |

## F-1: _executeHedge retry loop 没接 getFailoverChain

J2 ship getFailoverChain helper, 但 `_executeHedge` (trade-protocol-filter.js) 仍单次 placeOrder. primary fail → emit hedge_failed → 结束. 不 trigger failover.

NWT N19.69 spec 写 retry loop:
```javascript
let account = ...selectHedgeAccount(...);
const failoverChain = await getFailoverChain(account.exchange);
let attempts = 0;
while (true) {
  const result = await placeOrder({...});
  if (result.ok) break;
  attempts++;
  if (attempts >= 3 || failoverChain.length === 0) break;
  const nextCex = failoverChain.shift();
  account = getAccountByName(nextCex);
  console.log(`[hedge-router] ${result.error}, fallback to ${nextCex}`);
}
```

**J2 接 5-2 ship 时一并补这 ~15 LOC** (file 同样 trade-protocol-filter.js, scope nearby). 不开新 commit.

## F-2: regression test `hedge_router_capability_routing.test.mjs`

NWT N19.69 R-6 spec 要求 4-path regression (small_order / k_floor / auto_e2e / failover). J2 smoke test PASS 但 not committed.

简单 4 case static test (不真 fire hedge, 只测 selectHedgeAccount return route):
```javascript
import { selectHedgeAccount } from '../../../src/services/hedge-router.js';

// Phase 1: router enabled, mode=production, normal pool → default (bybit)
const r1 = await selectHedgeAccount({ orderValueUsdt: 100, side: 'SELL' });
assert(r1.route === 'default');

// Phase 2: small order ($3 < $5) → kucoin
const r2 = await selectHedgeAccount({ orderValueUsdt: 3, side: 'SELL' });
assert(r2.route === 'small_order');

// Phase 3: auto_e2e mode → gateio
const r3 = await selectHedgeAccount({ mode: 'auto_e2e', orderValueUsdt: 100 });
assert(r3.route === 'auto_e2e');

// Phase 4: caller override → preferredCex
const r4 = await selectHedgeAccount({ preferredCex: 'kucoin', orderValueUsdt: 100 });
assert(r4.route === 'caller_override');
```

J2 接 5-2 ship 时一并 add (~50 LOC). 测试 framework scope, J2 ship.

## J2 5-2 alarm fire 接续 — ack 立 ship 不等 (Owner 提速钦定)

J2 #557 main-line: 立 fire Phase 5-2 Sub-1 (KAS pool monitor). NWT ack. **J2 同 5-2 commit 含**:
- F-1 _executeHedge failover retry loop (~15 LOC)
- F-2 hedge_router_capability_routing.test.mjs (~50 LOC)
- 5-2 Sub-1 KAS pool monitor + 2 knob (~20 LOC)
- 5-2 Sub-2 CEX inventory snapshot + 1 knob (~30 LOC)
- 5-2 Sub-3 Owner notify path + throttle_log + v127 migration (~15 LOC)
- 5-2 Sub-4 trend endpoint (optional, defer to polish)

~130 LOC + 2 SQL migrations. ETA 2 hr (per J2 N19.70 estimate).

## NWT 接下来

- Standby reviewer 5-2 + F-1/F-2
- 起 5-5 stress test architect spec 并行 (5-4 已 broadcast, 5-5 unblocked by 5-2.5 ship)
