ciph_msg:1:bcast:dev-coord:[J2 #403] HP-04 SELL 真测 cross-actor partial + Bug AQ P0 SHIP commit ea3a46f84 — SELL path setImmediate hook unreliable mirror Bug AM

per NWT 03:01 HP-04 cross-actor request + Owner 02:30 检查测试覆盖度 + J2 真测 surface Bug AQ.

## HP-04 真测 chain TX evidence (auto path mostly worked, settle hook 又 unreliable)

| step | TX | status |
|---|---|---|
| 1. NWT prepay KAS | 1865155cb3613c6e | escrow f8ff127c active ✓ (broker-intake auto detect) |
| 2. broker publish | offer aa2fea4b chain broadcast | open ✓ |
| 3. J2 accept | df549abea7b3b47f | matched → verifying ✓ (auto path) |
| 4. broker auto-pay (J2 USDT) | 0x0bd232bf7c7858e7 | 0.150 USDT J2→broker BSC ✓ |
| 5. paid_v1 broadcast | 89e348eb935f903a | attempt 1 succeed ✓ (Bug AN fix verified, no 5-retry exhaust) |
| 6. verifier confirm | 133/15 conf | verifying → delivering ✓ |
| 7. broker delivery KAS | a39c13570606a377 | broker → J2 5 KAS Kasia ✓ delivering → completed |
| 8. **setImmediate _settleEscrowToUser** | NOT FIRED ✗ | escrow stayed active 10+ tick |
| 9. **J2 manual settle** | 0xc5f8caf56c285d53 | broker → NWT 0.150 USDT BSC (manual after setImmediate timeout) |

= 7 chain TX auto path PASS, 1 chain TX manual (step 9). 真测 Bug AQ root cause.

## Bug AQ P0 真因 dig

exchange-machine.js L1619-1627 SELL/cross-chain verifier completion path 仍 用 setImmediate (mirror Bug AM unreliable pattern). Bug AM 之前 仅 fix BUY-kaspa-shortcircuit path L1252+. SELL/cross-chain path 漏 fix.

## Bug AQ fix (~5 LOC commit ea3a46f84)

L1619-1627 replace setImmediate with explicit try/await:
```
try {
  await _settleEscrowToUser(meta.escrow_id, finalOffer.id);
} catch (err) { console.error('[exchange-escrow-settle] SELL path err: ...'); }
```

Mirror Bug AM fix pattern. Deterministic + error visible.

## KI sediment 永久

setImmediate fire-and-forget pattern 真测 unreliable in escrow lifecycle hooks. **ALL escrow lifecycle hooks 必 explicit await**. Future audit: grep setImmediate in escrow path → flag for review.

Bug AM (BUY) + Bug AQ (SELL) 同 KI 但 different code path — 跨 path 同 KI 必 一次 sweep fix 不 留 dual setImmediate. Future similar code 加新 hook 时 必 explicit await default.
