## P0 ship done — commit 6f1626059 (~6 LOC + 4 test)

state-machine.js chain menu 6 chain (align Phase 2 β prefund):
- SUPPORTED_CHAINS + _chainSelectText + _handleTradeFlow chains 全 6 chain (bsc/eth/polygon/arbitrum/optimism/base)
- _chainSelectText 加 5️⃣ Optimism + 6️⃣ Base (USDC) + 错误 msg 1-4 → 1-6
- 4 source-pattern regression test PASS (broker_v3_menu_6_chain.test.mjs)

## P1 ship done — commit e887d163a (~152 LOC)

### 1. exchange-client.js 加 4 endpoint helper

| helper | endpoint |
|---|---|
| submitPayment | POST /api/exchange/submit-payment |
| confirmOffer | POST /api/exchange/confirm |
| disputeOffer | POST /api/exchange/dispute |
| resolveOffer | POST /api/exchange/resolve |

### 2. state-machine.js _handleWaitPayment 重写

user 接 offer 后真链转 USDT 后可:
- 回 "我付了 0x<tx>" OR pure 0x[40-66 hex] → triggerSubmitPayment, broker 提交 verify
- 回 "争议" / dispute / 纠纷 → triggerDispute
- 回 数字 / 状态 / status / 查 → triggerOfferStatus
- 其他 → 显示 4 选项 prompt

### 3. state-machine.js _handleMyOrders translate protocol_status

11 状态 readable action prompt:
- open: '挂单中 (等 taker 接单). 可回 6 取消.'
- matched: '已被 taker 接单, 等 taker 真链付款.'
- verifying: 'broker 验证 taker 付款中 (cross-chain TX). 30-60s 完成.'
- delivering: 'broker 真链交付 KAS 到 taker 中. 30-60s 完成.'
- completed: '✓ 交易完成. KAS 已交付.'
- cancelled: '✗ 已取消. fund_lock 已释放.'
- refunded: '✗ 已退款 (timeout/dispute). fund 已退回.'
- failed: '✗ 失败 (verify 3 retry 后 fail OR 内部错). 走 dispute 启争议.'
- expired: '⏱ 已过期 (TTL 30min 无 taker). fund_lock 已释放.'
- disputed: '⚠ 争议中, 等 arbiter resolve. 联系 Owner.'
- timed_out: '⏱ verify 超时 (taker 未真付). 已 reopen.'

### 4. router.js trigger dispatch 加 2 case

- triggerSubmitPayment → _doSubmitPayment(client.submitPayment + reply '验证中 30-60s')
- triggerDispute → _doDispute(client.disputeOffer + reply 'Owner arbiter 介入')

## BSC 1 chain user 菜单闭环 verify ✓ (post P0+P1 ship)

| step | menu | flow |
|---|---|---|
| 1 | "1" BUY OR "2" SELL | CHAIN_SELECT → QTY → (SELL:ADDR) → CONFIRM YES → publish ✓ |
| 2 | publish reply | "✓ 挂单已上链 offer_id xxx 回 5 看 / back" |
| 3 | "3" BROWSE_MARKET | 列 active offers 1-5 + next 翻页 |
| 4 | "4" ACCEPT_OFFER | offer_id → CHAIN_SELECT → CONFIRM YES → accept + **payment guide (broker BSC addr + amount + USDT chain)** |
| 5 | WAIT_PAYMENT | user 真链转 USDT → 回 "我付了 0x<tx>" → submit-payment → 协议层 verify → auto deliver KAS |
| 6 | "5" MY_ORDERS | 状态 + readable action ("挂单中 等 taker 接单. 可回 6 取消" 等 11 状态) |
| 7 | "6" CANCEL | offer_id → CONFIRM YES → POST cancel (NWT 5/13 实证 PASS open-state 18s) |
| 8 | dispute | WAIT_PAYMENT 回 "争议" → triggerDispute → POST dispute |

**BSC 1 chain 协议层 + 菜单 user 全闭环** ✓

## Phase 2 β BSC 真链实证 仍 valid (协议层不动)

5/12 J2 #326 BSC e2e PASS (publish→completed 2 min 8s 8 行 chain_events trace) — Phase A.2 archive LLM + Phase B P0/P1 fix 完全不动协议层 (/api/exchange/* + exchange-machine.js + trade-protocol-filter.js + cross-chain-verify.mjs + settler-router.js).

## standby NWT review

NWT 走 5+ 步 audit:
- commit 6f1626059 diff (chain menu 6) + e887d163a diff (4 helper + WAIT_PAYMENT + MY_ORDERS + dispatch)
- broker-v3 menu user 闭环 verify (post Console restart)
- BSC 1 chain user flow 端到端 trace
- exchange domain Phase 2 β 不退

ETA Phase B close ~30 min NWT verdict + browser 实测 + audit doc sign.
