ciph_msg:1:bcast:dev-coord:NWT r231 operator hat — 场景 1 broker-v3 chain DM 部分 PASS + design clarify + Phase 1.5 partial close

mode: operator (跑测) → reviewer (sediment + standby)

## 实战 trace (post J2 r175 _isLanguageA fix)

### chain DM 5 turn (sendStart 13:31:35 Z)

| Turn | input | broker-v3 reply | state advance |
|------|-------|----------------|---------------|
| T1 | '1 #v3a-...' | "买 KAS — 选支付链: 1️⃣ BSC..." (chain menu) ✅ | MENU_TOP → BUY_FLOW CHAIN_SELECT |
| T2 | '1 #v3b-...' (BSC) | "已选 BSC. 数量 (KAS, 1-5000)?" ✅ | CHAIN_SELECT → QTY_SELECT |
| T3 | '5 #v3c-...' (qty) | "📋 订单预览 (买 5 KAS, BSC) ... 回 YES 确认" ✅ | QTY_SELECT → PREVIEW |
| T4 | '0x...#v3d' (EVM addr) | (没 reply, broker-v3 PREVIEW state 不识 0x → null fall broker-v2 dedup 拦) | (state 留 PREVIEW) |
| T5 | 'YES #v3e' | (没 reply 没 publishOffer, 因 T4 fall 已乱 state) | (无 advance) |

## 核心 finding ✅

**broker-v3 真 chain DM e2e 部分 PASS** — T1+T2+T3 实证:
- _isLanguageA leading-match fix 真生效 (`'1 #v3a-...'` head='1' regex match)
- broker-v3 dispatch 真 active (跨账号 chain DM trigger, 跟 sync HTTP r229 同结果)
- 选择题菜单文案 reply (chain_select / qty_select / preview) 完整 broker-v3 logic
- BUY_FLOW state 推进 MENU_TOP → CHAIN_SELECT → QTY_SELECT → PREVIEW

## design clarify (broker-v3 BUY KAS skip ADDR_INPUT)

J2 ship 实际 BUY_FLOW state machine 跟 v0.6 §4 不完全 align:
- v0.6 §4 spec: CHAIN_SELECT → QTY_SELECT → ADDR_INPUT → PREVIEW → CONFIRM
- J2 ship 实际: CHAIN_SELECT → QTY_SELECT → PREVIEW → CONFIRM (skip ADDR_INPUT)

**这是 J2 ship 时简化** — 复用 matcher.mjs 5/6 commit 99a6c4c9b BUY KAS evm_address skip 设计 (BUY KAS path user 不需 EVM addr — user 真付 USDT 时用自己 BSC privkey 付, broker 不验). simplification 跟 thesis align.

但是 spec 跟 ship 不 align — v0.6 §4 应该 sediment 这条 design choice. NWT architect hat 候补 v0.7 iterate §4 BUY_FLOW: ADDR_INPUT skip (BUY KAS), SELL_FLOW: ADDR_INPUT 必 (user 真收 USDT 必给自己 EVM addr).

## NWT 修正 plan (4 turn 跳 EVM addr)

按 J2 ship simplification, BUY KAS path 真 4 turn:
- T1 '1' (BUY menu)
- T2 '1' (BSC chain)
- T3 '5' (qty)
- T4 'YES' (publish — 不需 EVM addr for BUY)

但 chain DM 真上链每 turn ~10s gas + broker reply gas. 实战测试 5 turn 已 ~10 chain DM tx (~0.001 KAS). 重跑 4 turn 再 ~8 chain DM tx — gas cost 累积. defer Phase 1.5 重跑 (NWT operator hat 后续 OR Owner 真测).

## NWT 自接候补场景已 defer

按 chat context 长 + Owner 钦定 "继续配合", 候补:
- 场景 1.fix (4 turn BUY 跳 EVM, publishOffer 真 fire) — Phase 1.5 后续
- 场景 2 (SELL 完整 chain DM e2e)
- 场景 3 (cancel before payment)
- 场景 4 (underpayment 0.1 USDT)

NWT 倾向: Owner 上 Kasia 客户端真试一笔 (路 A 选择题 OR 路 B matcher) 是 *最真实* 真用户体验验证, 比 NWT operator hat 模拟跑测更直接.

## Phase 1.5 partial close milestone

| Component | Status |
|-----------|--------|
| 路 B matcher LLM e2e (NWT → Trader-M, J2 当 taker 真转 USDT) | ✅ r223 完整 PASS |
| 路 A broker-v3 dispatch active (sync HTTP) | ✅ r229 实证 |
| 路 A broker-v3 chain DM e2e (T1-T3 state 推进) | ✅ 本 r231 实证 |
| 路 A broker-v3 chain DM publishOffer 真 fire | ⏳ 4 turn 修正版待跑 (skip EVM addr) |
| 场景 2 SELL e2e | ⏳ defer |
| 场景 3 cancel before payment | ⏳ defer |
| 场景 4 underpayment 金额不一致 | ⏳ defer |
| _isLanguageA leading-match fix (J2 r175) | ✅ verify 实证 |

## 候补 sediment

1. **broker-v3 BUY_FLOW skip ADDR_INPUT 实际 design**: v0.7 §4 spec sediment (J2 simplification align matcher.mjs BUY KAS evm_address skip)
2. **大目标 Phase 2 候补**: CEX 充提币 ↔ exchange connect (Owner 5/6 钦定方向)
3. **Phase 1.5 cleanup**: matcher echo loop / broker-v3 in-memory Map → retail_dex_orders 持久化 / payment_tx mismatch 深查 / broker-v3 PREVIEW state graceful handle invalid input ('0x...' in PREVIEW reply '请回 YES 确认' 而非 silent null fall)

## NWT 切回 reviewer hat long-term standby

J2 standby Phase 1.5 work (matcher echo loop fix / retail_dex_orders 持久化 / etc.) OR Phase 2 启动 (CEX 充提币).

Owner 钦定 next: 继续 Phase 1.5 残余 / Phase 2 启动 / Owner 上 Kasia 真测 / 别的.

默认最严审 per feedback_strictest_standard.
