## 资源清单 (现状 audit)

### Trader-B (broker maker, relay `0a8e9723-f00b-4b10-8c79-1dbd4fe3cfb0`)
- Kaspa: **1857.084 KAS** (Kaspa fee budget 充足, 每 TX ~0.0003 KAS)
- BSC: **10.30 USDT** (post NWT #71 funding 0.20 to Trader-A) + **0.0014 BNB** (~$1.5 gas margin)
- 9-chain EVM/SOL/TRON addresses configured (relay-managed wallets, balance 0 except BSC)

### Trader-A (taker, relay `df8cd0f9-27e7-45c6-bbea-2fa11a1ff1cd`)
- Kaspa: **3.49 KAS** (accept + cancel × 多笔够用, ~0.005 KAS per TX)
- BSC: **0.20 USDT + 0.0005 BNB** (post NWT funding ✓)
- 9-chain wallets configured (balance 0 outside BSC)

### Owner #70 钦定 "自动调配, 自动兑换" 实证

Path C 不需 EVM/SOL/TRON funding — publish/accept 全 Kaspa chain TX, EVM/SOL/TRON addr 只是 publish payload metadata (不发实际 EVM/SOL/TRON chain TX). 已 sufficient ✓

Path A BSC full e2e 已 internally funded Trader-A (0.20 USDT + 0.0005 BNB from Trader-B). 已 sufficient ✓

= **资源现状够 A+C 全 scope, 不需 cross-chain swap/bridge** ✓

## 对手方配置

| role | identity | reasoning |
|------|----------|-----------|
| broker maker | Trader-B relay `0a8e9723-...` | broker = service agent, KAS wallet funded + BSC USDT funded |
| taker | Trader-A relay `df8cd0f9-...` | taker = customer agent, 跟 broker 独立 relay (R4 self-deal guard 守 ✓), Kaspa funded + BSC funded |
| watcher | bsc-incoming-watcher (already running on console) | Trader-B receives USDT triggers watcher detect |

## Test Goal alignment check (must not drift)

| Owner #46 goal | test method (per chain) | 一致性 |
|----------------|------------------------|--------|
| broker 菜单完全工作 | DM Trader-B 数字 → state machine reply chain | aligned (NWT #67/#69 partial verified) |
| 完全融合 exchange 大循环 | publish on-chain → accept on-chain → (Path A only: paid + delivered + completed) | aligned |
| 别搞那么多版本 | broker-v3 menu single dispatch | aligned (post NWT #68 env restore) |

= test method 跟 goal 一致 ✓ (Path A close full e2e gap, Path C cover 9 chain dispatch breadth)

## Test Sequence Design

### Phase 1: Path C — 9 chain × BUY publish + accept (partial, $0 real money)

per chain N in [bsc, eth, polygon, arbitrum, optimism, avalanche, base, sol, tron]:

```
[BUY_FLOW skip ADDR_INPUT — taker pays USDT, broker sends KAS, taker addr not pre-declared]

Step 1 broker publish:
  fresh_peer = `kaspa:test-pathc-buy-${chain}-${ts}`
  call broker-v3 router.handleMessage(fresh_peer, '1', {relayNodeId: Trader-B})  → BUY_FLOW CHAIN_SELECT
  call ...handleMessage(fresh_peer, ${chain_num}, ...)                            → QTY_SELECT
  call ...handleMessage(fresh_peer, '5', ...)                                     → preview (no ADDR_INPUT)
  call ...handleMessage(fresh_peer, 'YES', ...)                                   → triggerPublish → /api/exchange/publish
  capture: offer_id + broadcast_tx (Kaspa) + chain selected + reply text

Step 2 taker accept:
  taker_peer = `kaspa:test-pathc-taker-${chain}-${ts}` (simulates Trader-A user identity)
  call broker-v3 router.handleMessage(taker_peer, '4', {relayNodeId: Trader-B})  → ACCEPT_OFFER OFFER_ID_INPUT
  call ...handleMessage(taker_peer, offer_id, ...)                                → CHAIN_SELECT
  call ...handleMessage(taker_peer, ${chain_num}, ...)                            → CONFIRM
  call ...handleMessage(taker_peer, 'YES', ...)                                   → triggerAccept → /api/exchange/accept
  capture: accept_tx + reply text (maker chain addr returned)

Step 3 verify (no real money):
  query exchange_offers WHERE id=offer_id → state='matched', accept_tx populated
  (matched offers will timeout in 30min, no manual cancel needed)
```

cost: 9 × 2 Kaspa TX = 18 Kaspa TX × ~0.0003 KAS = ~0.005 KAS (~$0.0002)
duration: ~5-10 min total (no real chain wait)

### Phase 2: Path A — BSC SELL full e2e (real settlement, ~$0.10 remaining)

NOTE: Use **SELL flow** (user sells KAS, broker buys KAS) — opposite direction from Path C BUY:
- broker (Trader-B) has KAS to sell to user — wait, SELL means user sells. Re-reading menu...
- Actually broker-v3 menu '2' = "卖 KAS" from USER perspective = user sells KAS
- = user gives KAS, broker pays USDT
- But we want broker maker, taker pays USDT

Re-design Path A as **BUY flow** (跟 Path C 同):
- broker-v3 menu '1' = "买 KAS" from USER perspective = user buys KAS
- = user pays USDT, broker sends KAS
- Trader-A as user buys 5 KAS BSC, pays 0.20 USDT to Trader-B
- broker auto sendKas to Trader-A's Kaspa addr

sequence:
```
Step 1: broker publish (5 KAS BSC BUY offer):
  fresh_peer = `kaspa:test-patha-bsc-${ts}`  ← actually use Trader-A's Kaspa addr as peer for taker linkage
  call broker-v3 with peer=Trader-A-kaspa-addr, '1' → BUY_FLOW
  '1' (BSC) → '5' (KAS) → 'YES' → publish [...]
