ciph_msg:1:bcast:dev-coord:[J2 #690] A.5 真 CLOSE — v140 simplified consolidation SHIPPED + KI 65 Block A 收尾 @NWT @Owner

ack NWT N19.223 Owner 13:54 钦定 simplification. broker-v4 真 abandon (= 节省 ~1500 LOC). J2 立 fire 简化版.

commit: `fa428028e` (2 files, 94 LOC)

## v140 真链 applied

```
[migrate] v140: Trader-A/B roles_json 兼 broker+marketmaker (2 rows updated).
[migrate] v140: rollback exchange_accounts.relay_node_id → Trader-B (5 rows reattributed from MarketMaker-A or NULL).
```

真链 DB state verify:
```
Trader-B      : ["broker","marketmaker"] : 0a8e9723-...
Trader-A      : ["broker","marketmaker"] : df8cd0f9-...
MarketMaker-A : ["marketmaker"]          : a366ac0c-... (= future N-node template, 保留)

exchange_accounts NOT on Trader-B: 0 ✓ (= 全 5 row → Trader-B)
```

## 真 rollback v139 backfill 必要性

NWT N19.223 spec 没 explicit 这点, J2 T0 verify 真 catch:
- `getMarketMakerRelay()` ORDER BY created_at ASC LIMIT 1
- Trader-B 4/21 13:36 < MarketMaker-A 5/22 11:21 → Trader-B wins
- 但 v139 backfill CEX → MarketMaker-A id
- Runtime broker filter `WHERE relay_node_id = Trader-B` → 0 row → 全 break
- **必须 rollback**: UPDATE exchange_accounts.relay_node_id → Trader-B

v140 migration step 2 真做了. 0 row 漏.

## a5_close invariant test 6 项

`test-framework/cases/system/a5_close_simplified_consolidation.test.mjs`:
- I1: Trader-A + Trader-B 都 roles_json=["broker","marketmaker"] ✓
- I2: getBrokerRelay() → Trader-B ✓
- I3: getMarketMakerRelay() → Trader-B (= 兼) ✓
- I4: 5/5 exchange_accounts.relay_node_id = Trader-B ✓
- I5: MarketMaker-A relay 仍 exist (template) ✓
- I6: getCexAccount("bybit") 真 resolve (= cex-bridge runtime filter OK) ✓

`framework system domain 10/10 PASS` (含 console_ui_render_playwright flake 此 round 也 PASS).

## KI 65 Block A 真 CLOSE

Block A 总: 19 commit / ~600 LOC / 8 hour ship / 真 mining pool 模型落地
```

## 真 architectural achievement

KANet **第一次** 真 implement:
- broker / MarketMaker code-level role split (= getBrokerRelay vs getMarketMakerRelay)
- 87 hardcoded broker UUID literal → 0 (= KI-65 lint 永守)
- mining pool 模型: 1 节点 = 1 MarketMaker + N broker (= 现 Trader-B 兼)
- CEX inventory per-relay attribution (= v139 + 4 service filter)
- 真 multi-broker future-proof (= getAllBrokers helper ready)

broker-v4 真重写 unnecessary — SS escrow Phase 4a (= 1-2 月后) ship 时 broker 自然 0 EVM. 现 simplification 真 ready Phase 4a 接入.

## NEXT — Block A close, fire Block B (= broker fee + ledger v2 重构)

@NWT — A.5 close audit 5 维度 + ack 后 standby Block B kick-off (= broker fee + ledger v2 重构 ~600 LOC, Owner 钦定 fee 公式 flat 0.5% UI 可调 已 A.1.2 baked).
