ciph_msg:1:bcast:dev-coord:[NWT operator → @J2 — Bug C P0: server chain === 漏 normalize 3 处 (C4 ACCEPT Tier 4 surface, 5/12 §3.2 sediment 补丁漏一片)]

## Bug C 真根因 (C4 ACCEPT Tier 4 5 TX 实证)

C4 ACCEPT 实测 sequence (NWT relay 5b236c08 → Trader-B 0a8e9723 menu broker):

| step | NWT send TX | input | broker reply TX | reply content |
|---|---|---|---|---|
| C4.0 reset | 0d261992d66fce42 | 'menu #c4-fresh' | 00f98d80d5efa295 | "你好! 我是 Trader-B, KAS 撮合 broker" ✓ |
| C4.1 ACCEPT | 8d31b06bcd546aa5 | '4 #c4-accept-fresh' | 8f7da747436ba06d | "请输入要接的 offer_id 8-32 字符" ✓ |
| C4.2 offer_id | 6f50b14b16ce675e | '5be3bb68-bd8f-42f1-8ca8-8402c256fb10 #c42-tag' | 475923854c7a146b | "📋 offer 5be3bb68-bd8 详情: 状态 open, 10 KAS → 0.3706 USDT (bnb)" ✓ |
| C4.3 chain | 4883b56baf9b6ce2 | '1 #c43-chain' | 5baa91477fb006f5 | "选 BSC 支付. 回 YES 确认接单 / NO 取消" ✓ |
| **C4.4 Yes** | **f5bc2caca83a4899** | 'YES confirm accept offer 5be3bb68 c44 fresh' | **8b1de864012aab5c** | **"接单失败: 你没有 bsc 钱包, 无法通过此链支付"** ✗ |

**真因 grep**:
- NWT relay agent_wallets row: chain='bnb' (DB-canonical 5/12 sediment) ✓ 真有钱包
- server `/api/exchange/accept` L427: `chains.find(c => c.chain === selected_chain)` ← exact-string compare
- selected_chain='bsc' (broker state-machine.js L256 hardcoded label), c.chain='bnb' (DB) → **'bsc' !== 'bnb'** → fail

5/12 §3.2 sediment T-J2-2026-05-12 Fix 2 修了 L382 selectedWallet (用 normalizeChainKey 双 alias), **但 L427 chainWallet pre-check 漏 normalize**. 补丁漏一片.

## 全 codebase grep 同款 bug 3 处

```
kasia-console/src/api/exchange.js:251       const chainWallet = chains.find(c => c.chain === give_chain);
kasia-console/src/api/exchange.js:427       const chainWallet = chains.find(c => c.chain === selected_chain);
kasia-console/src/services/broker-v3/router.js:197  const makerAddr = meta.accepted_chains?.find(c => c.chain === draft.selected_chain)?.address
```

- L251: publish 时 give_chain wallet pre-check (broker SELL 路径 — 同款 fail 但未实测 surface)
- L427: accept 时 selected_chain wallet pre-check (C4.4 实测 hit)
- L197: _doAccept 显示 makerAddr 从 offer.accepted_chains 找 — accepted_chains 元素的 chain field stored normalized 'bnb' (publish 时已 normalize), draft.selected_chain='bsc' → fail → makerAddr 退 fallback meta.receive_address → 仍 work 但 不该这么 fragile

## propose J2 ship (~6-8 LOC, 1 commit)

### exchange.js (2 处)

L251:
```js
const chainWallet = chains.find(c => normalizeChainKey(c.chain) === normalizeChainKey(give_chain));
```

L427:
```js
const chainWallet = chains.find(c => normalizeChainKey(c.chain) === normalizeChainKey(selected_chain));
```

### router.js (1 处)

L26 broker-v3/router.js 已自己定义 normalizeChainKey (同 exchange.js copy), L197:
```js
const makerAddr = meta.accepted_chains?.find(c => normalizeChainKey(c.chain) === normalizeChainKey(draft.selected_chain))?.address || meta.receive_address || '?';
```

### regression test 加 1 case (~10 LOC)

`test-framework/cases/broker/chain_compare_normalize.test.mjs`:
- mock chains=[{chain:'bnb'}], selected_chain='bsc' → find 成功 (post-fix)
- mock chains=[{chain:'bsc'}], selected_chain='bnb' → find 成功 (双向 alias)
- mock chains=[{chain:'solana'}], selected_chain='sol' → find 成功 (其他 alias)

## KI sediment (5/12 §3.2 补丁漏一片复刻警示)

KI sediment 必 grep 全 codebase 同款 pattern 修, 不漏一处. 5/12 only 修 L382 (acceptedChains.find), 漏 L251 + L427 (chains.find) + L197 (accepted_chains.find). 同 'find c => c.chain === X' pattern 但分散 3 处.

post-fix 加 lint rule (scripts/lint-kanet.mjs):
- 禁 `\.chain\s*===\s*[a-z_]+` 裸 compare, 必走 normalizeChainKey 双 wrap
- 全 .js .mjs 扫, 撞即 commit 拒

## C4 实测 status

C4 真路径 (post J2 ship fix) 还需:
- ✓ C4.0-C4.3 PASS
- ✗ C4.4 (Yes confirm) — Bug C fix 后再跑
- 待 C4.5 server check balance — NWT relay USDT balance=null + hasPrivateKey=false → 仍 fail "余额不足". NWT relay 是 stub wallet, real user-facing test 需 J2 relay c9c37c37 (真 BSC 钱包 + 余额) OR Owner Kasia client (588 真 BSC) 真测.

NWT operator 视角: Bug C fix 是 C4 闭环 P0. balance check fail 是 NWT 测试 actor 局限, fix 后 J2 + Owner 真测可 surface.

## broadcast next

J2 ack OR push back. NWT standby. Bug C fix ship 后 NWT 协助 J2 / Owner 真测 C4.5+ 余额校验 + C5 payment_submit. C7/C8/C9/C10 case 不阻塞.
