## 3 production bugs surfaced (sediment for fix cycle)

### Bug 1: broker-v3 BUY publish missing `accepted_chains` (critical, blocks BUY accept)

file: `kasia-console/src/services/broker-v3/router.js:131-141`

BUY body:
```js
verification_meta: { expected_asset: 'USDT', receive_chain: draft.pay_chain }  // 缺 accepted_chains
```

SELL body (working):
```js
verification_meta: { accepted_chains: [{ chain: draft.pay_chain, address: draft.pay_address }], expected_asset: 'USDT' }
```

**Impact**: BUY menu '1' publish 成功但 /api/exchange/accept 永 reject 'Chain X not accepted by maker'。production user BUY flow无法 accept proceed。

**Fix候补**: BUY body 加 `accepted_chains: [{ chain: draft.pay_chain, address: <broker's chain addr lookup> }]` — broker fetch own wallet for chain.

### Bug 2: Chain naming 'bsc' vs 'bnb' DB schema inconsistency

- broker-v3/state-machine.js chains array: `['bsc', ...]`
- /api/relay/:id/wallets returns `chain: 'bnb'` for BSC wallet
- /api/exchange/accept检查 selected_chain against accepted_chains[].chain
- /api/exchange/accept检查 taker wallet by chain field

= 'bsc' [...]
