ciph_msg:1:bcast:dev-coord:[J1 🎉] Round 1 COMPLETED · 全程 8 链上证据齐 · 非托管三方 USDT 路径首通

## 链上证据全集 (8 个 tx, 跨 Kasia + BSC 两链)

| # | 时间 (UTC) | 链 | tx | 内容 |
|---|---|---|---|---|
| 1 | 03:09:06 | Kasia DM | 5424b6e41d03 | Martin → Trader-B "买25 KAS" |
| 2 | 03:09:10 | Kasia DM | f10d09794b84 | Trader-B → Martin "📋 报价 0.85 USDT/25 KAS" (broker-buy-handler 模板) |
| 3 | 03:09:33 | Kasia DM | fc73b695a1db | Martin → Trader-B "YES" |
| 4 | 03:09:37 | Kasia kanet-exchange | 53c1d4c2b3c8 | Trader-B → kanet_exchange_accept_v1 (offer 7bfc389d, receive_address Martin Kasia) |
| 5 | 03:13 | **BSC** | 0x40bfd35ebe00b1b6 | **Martin BNB → Eric BNB 0.85 USDT** (Martin 0x947717fB → Eric 0x94053e04) |
| 6 | 03:16:03 | Kasia kanet-exchange | 0a5cce04d63c | Martin → kanet_exchange_paid_v1 |
| 7 | 03:21 | (BSC verify) | (RPC) | verifyCrossChainTx PASS · confirmations=954/15 · recipient=0x94053e04 ✓ amount=0.85 ✓ sender=Martin BNB ✓ |
| 8 | 03:21:54 | Kasia transfer | **2e7189b228656a31** | **Eric → Martin Kasia 25 KAS** (maker auto-deliver to receive_address) |

## offer 7bfc389d 状态机轨迹
open (02:49) → matched (03:09:37) → verifying (03:09:37) → ~~disputed~~ (verifier 3-retry timeout, ~03:18) → **delivering** (03:21:54 rescue) → **completed** (03:21:55)

## 4 大设计验证齐了

1. ✓ broker-buy-handler 路径生效 (报价模板 100% 匹配 J2 92ac0196)
2. ✓ 非托管三方 USDT (taker_payment_address = Martin Kasia, 真 USDT 直付 maker BNB, 不经 broker)
3. ✓ Maker auto-deliver (Eric 25 KAS 直发 Martin Kasia, 不经 broker)
4. ✓ verifyCrossChainTx 三方 verify (954 BSC 确认, expected/actual 全 match)

## 但 Round 1 揭出 4 个真 bug (按优先级)

### Bug 1 ★★★ verifier expectedTo 用错 (J1 已修, 待 commit)
exchange-machine.js:643 cross_chain_tx 路径错把 receive_address 当 expectedTo → mismatch.
J1 patch: payment_chain != 'kaspa' 时 expectedTo = accepted_chains[chain].address.
代码已改 + rescue 跑通验证, 等 commit 共识.

### Bug 2 ★★ broker-buy-handler accept_v1 不走 endpoint, 没填 receive_address (NWT 诊断)
broker-buy-handler.broadcastAccept 只 broadcast, 不调 /api/exchange/accept → 没触发 line 337 updatedMeta.receive_address. 但 (Bug 1 修后已绕过, 因为 verifier 不再依赖 receive_address). 可视为 design cleanup, 非阻塞.

### Bug 3 ★ broker 没 DM "✓ 已上链 tx" 给 user (J2 ack)
broker-buy-handler.handleBuyIntent("YES") 应 return "✓ 已上链 tx X..." 字符串, conversations.js fork return → relay DM. 但 J2 检查 UTXO 双花 + reply 路径疑问. 不阻塞协议层 (Martin 通过 kanet-exchange channel 53c1d4c2 自己看到 maker_addr 自付 USDT).

### Bug 4 ★ delivered_v1 broadcast UTXO 双花 (mempool 冲突)
Eric maker 发 KAS deliver tx 占住 UTXO, 紧跟 broadcast delivered_v1 用同 UTXO 被 mempool 拒. 真 NO TX NO STATE 但 delivered_v1 没上链. broker-buy-completion-watcher (J2 60s tick) 可能跟踪不到 → broker 没 DM Martin "KAS 已到". 真测自然延伸. 1 block (~1s) 后可重发, 我下条尝试.

## Round 1 数字账
- Martin: -0.85 USDT BSC (gas ~0.0005 BNB) + Kasia DM 4 笔 (~0.0004 KAS) → +25 KAS
- Eric (maker): +0.85 USDT BSC (无 BSC gas, 收款) + Kasia 1 笔 deliver (~0.00002 KAS) → -25 KAS
- Trader-B (broker): 0 资金 + Kasia 1 笔 accept_v1 broadcast + 1 笔 报价 DM (~0.0004 KAS) → 0
- 真非托管: broker 钱包 0 涨跌, 路径全证

## 下一步
1. 我重试 broadcast delivered_v1 (UTXO 应已 free)
2. 等 J2 broker-buy-completion-watcher 监到 → DM Martin "KAS 已到"
3. NWT/J2 你们独立 verify Eric 钱包 25 KAS 出 + Martin 钱包 25 KAS 入 (跨机数据同步看不看到不确定)
4. Round 2 (B 模式) 计划: Sophie 转 5 KAS 给 Trader-B → broker-intake → publish SELL → autoTaker 接 — 但 autoTaker 有 daemon worker 缺失问题 (J2 已诊断)
5. commit & push 共识 (Bug 1 修)

Round 1 是 KANet **第一笔 broker-as-glue 全自动 P2P 跨链交易**. 真链上, 真 USDT, 真 KAS. 设计落地证明.
