ciph_msg:1:bcast:dev-coord:[NWT operator + architect → @J2 — BSC menu mode open-state cancel 闭环实证 PASS + Phase A delete + Phase B UI browser 实测分工]

coord-ack: ffcd4778 (NWT Phase A.2 spec) + Owner 5/13 20:30 严训 "纯菜单模式纯粹+可靠+逻辑闭环+功能闭环" + Owner 20:40 钦定 "好, 你去和 J2 对齐"

## 1) BSC 菜单 open-state cancel 完整闭环实证 PASS (NWT operator 5/13 20:38)

NWT 跑 BSC 一条最小 cancel flow (curl 模拟 UI button), 实证:

| step | 操作 | 实证 |
|---|---|---|
| publish | POST /api/exchange/publish BSC SELL 1 KAS want 0.05 USDT | ✓ offer fac9cc32 state=**open** + broadcast_tx 64630092 上链 + fund_lock 1 KAS locked |
| cancel | POST /api/exchange/cancel | ✓ state=**cancelled** + cancel_tx a190c85c 上链 + fund_lock **released_at set** |
| lifecycle | 18 秒完整 (13:38:16 publish → 13:38:35 cancel released) | clean, KAS 不卡 |

**协议层 + state machine + endpoint + fund_lock 全 align**. UI button `exchange.eta:1472 cancelOffer` 走同一 endpoint (`fetch /api/exchange/cancel`), 跟 curl 行为一致.

## 2) "随时撤销" 协议层设计澄清

实证 + grep code:
- ✓ open state: maker 随时可 cancel (publish 后 → 接单前任意时间)
- ✗ matched state: cancel ignored (exchange-machine.js L514 注释 "After matched, cancel is ignored")
- matched 后改走 **dispute → resolve** (5/12 stress test #4 已 fix resolve endpoint)

正确设计: matched 后 maker 撤 = 违约 (taker 已 commit USDT). 协议保护 taker 经济利益. 跟"随时"语义错位需 Owner 澄清:
- 现实施 = open state only cancel
- "随时" 含义? matched 后 cancel 默认 = grace period? OR 永远 dispute?

NWT 建议保留现 open-state-only cancel, 用户 UI 加 hint "matched 后改走 Dispute 按钮". 不动协议层. 跟 J2 align 时同看.

## 3) Phase A.2 J2 ship trigger

J2 接 NWT spec ffcd4778 Phase A.2 ~3 hr ship:
- archive broker-v2/ + broker-llm-agent + broker-buy-handler + broker-sell-handler (4 files/dir, ~4171 LOC)
- conversations.js 删 LLM dispatch 段 (~150 LOC)
- kanet.env + kanet-start.sh 删 BROKER_V2 env
- archive LLM 老 test case (cross_peer / lifecycle / persona / llm_mock / wording-fragile 5 case 等)
- regression verify broker domain 0 FAIL (LLM case 已 archive 不再撞 cron) + exchange 不退

J2 ship 每 sub commit 后立即 broadcast. NWT standby reviewer.

## 4) Phase B menu mode audit 分工 (cross-hat)

### J2 (1-3 维度, implementor 熟 code + UI)

1. **/api/exchange/* 7 endpoint 完整 cover 菜单式** — J2 grep endpoint 列 + Phase 2 β e2e 真跑路径对照
2. **UI menu-select 完整 (chain/asset/amount)** — J2 browser 实测 /exchange page (Phase A.2 console restart 后):
   - publish form: chain dropdown 全 9 chain (or 5/13 β 7 chain 实证)? asset USDT/USDC/KAS? min/max amount?
   - browse list: filter/sort 完整?
   - accept flow: selected_chain dropdown 跟 offer.accepted_chains[].chain 一致?
   - cancel/confirm/dispute button x-show 条件正确?
   - **重点: browser 真 publish BSC offer → 看 list → click Cancel button → 看 state transition + cancel_tx + fund_lock 释放 (NWT 已 curl 实证, J2 browser 二次 verify)**
3. **协议自动 trigger 链路** — J2 grep _autoPayExchange/_autoSettleAsset 触发 condition, bridge-router 是否接 _autoPay (现 NWT operator 手动 fire, **broker 自动 multichain rebalance v0.4 backlog, Phase B 是否 P1?**)

### NWT (4-7 维度, architect 协议层)

4. **chain_events 8 行 trace 完整 multichain** — NWT grep 4 chain e2e chain_events row pattern
5. **fund_lock multichain 准确** — cancel/dispute/completed 各 path fund_lock 释放正确 (实证 NWT 已跑 open→cancel 18s)
6. **Error recovery** — bridge_initiated 但 LZ delivery fail / source TX confirmed 但 dest 不到 / dispute resolve workflow
7. **dispute / resolve UI + autoTaker boundary** — autoTaker (4/12 memory) 现 active? broker-v3 menu vs autoTaker 边界?

### Audit deliverable

`docs/menu-mode-audit-2026-05-13.md` ~200 行 7 维度 + 漏洞清单 P0/P1/P2 + fix priority. J2 + NWT 各 grep / 实测后 cross-verify 在 doc 双方签名.

## 5) ETA + 顺序

| phase | scope | owner | ETA |
|---|---|---|---|
| **A.2 archive** | J2 ship | J2 | **starting now**, ~3 hr |
| A.4 regression | J2 + NWT review | 30 min | post A.2 |
| **B audit** | NWT 4-7 + J2 1-3 cross-hat | both | 2-3 hr (post A.2) |
| B fix | per audit P0/P1 finding | NWT + J2 | TBD |
| Phase 3 SOL/TRON | NWT spec + J2 ship | 后续 | post audit close |

NWT 并行起 Phase B 4-7 维度 audit (~30 min spec 框架), 不撞 J2 Phase A.2 ship work.

## 6) cron baseline P1 close

Sub #1.a J2 ship 25cf53b16 ✓ + Sub #1.b retract (revert 12a0d22ab J2 已 ship 跟 NWT retract 同步 ✓) + Sub #1.c retract + Sub #2 retract + LLM 老 case 随 Phase A.2 archive.

cron baseline P1 实际 close 状态:
- A1 invariant violation 0 (Sub #1.a 修)
- LLM 老 case archive Phase A.2 后 cron 期望 ≥ 36/36 PASS (broker-v3 + 协议层 case only)

## standby

J2 ship Phase A.2 + B audit 1-3. NWT ship Phase B audit 4-7 + standby reviewer.

per Owner 5/13 钦定 "你去和 J2 对齐". 对齐 ✓.
