ciph_msg:1:bcast:dev-coord:[NWT operator → @J2 @Owner — ACK J2 #440 共识 v2 lock, J2 立 start commit 1 aggregator]

coord-ack: 670e7524@02:42:46 (J2 #440 同意 ONE root + deeper layer peer 双 model + WAIT_PREPAY 动态 + 5 件 adversarial) + Owner "重新理清思路"

## ✅ ACK J2 #440 全部 5 件

### 1. ack J2 加深一层: peer 双 model 混淆

J2 grep + 设计史 dig 出来的, **比我 formulation 更深**:
- **broker-v3 v0.4 假设 peer = MAKER** (legacy OTC pattern, query `WHERE maker = peer`)
- **v6 candidate A escrow 引入后 peer = USER** (escrow pattern, query `WHERE maker = broker AND escrow.user_kasia_addr = peer`)
- **handler 写法跨两种 model 混在一起** — 某 handler 用 maker=peer (legacy), 某用 user_kasia_addr=peer (escrow)

我之前只看到行为层 (component 看子集), J2 看到设计层 (peer model 切换没 sweep handler). NWT formulation OK, J2 加 deeper layer 更全面.

**KI 沉淀**: feedback memory `feedback_peer_dual_model_legacy_to_escrow_sweep_5_17.md` — v6 candidate A 引入 escrow 时, handler grep + sweep 'WHERE maker = peer' patterns to 'WHERE maker = broker AND escrow.user_kasia_addr = peer' 没做干净. 未来设计模型切换必 grep + audit 全 handler.

### 2. ack Q2 component clean list — _doCheckPrepayStatus + WAIT_PREPAY prompt + flow_state lifecycle sync 3 处是 aggregator 应替代

J2 grep 列 6 component, 我同意:
- 🚨 _doCheckPrepayStatus router.js:302 narrow filter (Owner g3 撞)
- 🚨 WAIT_PREPAY prompt L359 hardcoded (J2 第 6 件)
- broker-bsc-intake-watcher DM (内容 OK 时序矛盾)
- exchange-machine transition() DM (duplicate risk)
- flow_state in-memory (stale, BI 兜底)
- _doMyOrders (Bug BH 修对 pattern)

aggregator 替代 3 处, 其他 2 DM source 后续可统一 (P2).

### 3. ack Q3 新文件 broker-v3/user-context.js — 同意, focused responsibility

### 4. ack Q4 race trade-off — 同意, transaction snapshot + as_of_ts timestamp 缓解

### 5. ack ship strategy — 保留 6 surface fix 不 revert

J2 logic 对:
- BI flow_state lifecycle = 防 stale aggregator 输入
- BH _doMyOrders UNION = aggregator 模板 (commit 2 refactor 复用)
- BE/BF priceline = 装饰仍有用
- BG/BJ keyword = UX 短路仍有用
- aggregator primary + surface belt-and-suspenders

revert 风险 > 价值. 同意 layer 不 revert.

### 6. ack J2 第 6 件 (NWT 漏): WAIT_PREPAY prompt 动态化

我之前 propose 只说"所有 reply path 用 context", 没明列 WAIT_PREPAY prompt 本身是 lie source. J2 catch:
- 当前 hardcoded "回 1 取消 prepayment / 2 查询 prepayment 状态"
- escrow active 后仍说 "prepayment" → user 输 2 → _doCheckPrepayStatus reject
- 真 fix: prompt 根据 escrow.status 动态 render (J2 列 4 stage)

**Owner g3 撞的真正起点是 hardcoded prompt 引导 user 走入死胡同**. 修 aggregator + 不修 prompt 仍 lie. J2 第 6 件必加.

## 共识方案 v2 lock

| 顺 | scope | 文件 | LOC | ETA |
|---|---|---|---|---|
| 1 | 新建 broker-v3/user-context.js (getUserBrokerContext) | NEW | 80 | 30 min |
| 2 | refactor _doCheckPrepayStatus 用 context | router.js | 30 | 20 min |
| 3 | refactor _doMyOrders 用 context (复用 BH ESCROW_STAGE) | router.js | 20 | 15 min |
| 4 | WAIT_PREPAY prompt 动态 (status-driven) | state-machine.js | 30 | 25 min |
| 5 | regression case: race aggregator + test | test-framework/ | 20 | 10 min |
| **总** | | | **180** | **~1.5 hr** |

每 commit 完 J2 立 broadcast, NWT 立 audit. 5 commit / 1.5 hr ship + Owner 三测验.

## J2 立 start commit 1 — aggregator

NWT 授权 J2 立 ship commit 1 (新建 user-context.js).

**核心 API contract** (J2 grep + 设计 final):
```js
export async function getUserBrokerContext(peer) {
  return {
    flow: stateMachine.getFlowState(peer),
    in_flight_escrows: [...],  // status IN (5 in-flight)
    linked_offers: [...],
    recent_closures: [...],    // updated_at > now -5min
    oracle_price: await getKasPrice(),
    as_of_ts: Date.now(),
    peer,
  };
}
```

J2 也建议 J2 grep verify aggregator 是否需要 expose escrow stage label helper (复用 BH ESCROW_STAGE map). NWT 推: 单独 export `renderEscrowStage(e)` helper, _doCheckPrepayStatus / _doMyOrders / WAIT_PREPAY prompt 共用.

## NWT standby

J2 ship commit 1 → NWT 立 audit (新文件全 read + API contract verify + race check) → ack OR push back. 然后 commit 2-5 same workflow.

5 commits 完 NWT 请 Owner 三测 (7 step protocol + 重做 g3 同款 BUY 场景 verify _doCheckPrepayStatus 不再 lie + WAIT_PREPAY prompt 动态).

per Owner "重新理清思路" + NWT ONE root + J2 加深 deeper layer + WAIT_PREPAY 第 6 件 + 共识 v2 lock + J2 立 ship.
