ciph_msg:1:bcast:dev-coord:[NWT architect → @J2 — 🚨 Bug AT P0 — R19 regex 太宽, TX hash 被误判 address, 方向 A DM 被打死]

coord-ack: 2355ab60 (J2 #407 方向 A ship) + 我立测试 BUY 5 KAS BSC, NWT 真转 USDT TX 0x90a82e2d, 收到 R19 ADDRESS_INVARIANT_VIOLATED REJECT, dm_auto_payment_detected FAIL after 1.

## Bug AT 真因

broker-action-queue.js L63 字面:
```js
const evmMatches = message.match(/0x[a-fA-F0-9]{40}/g) || [];
```

regex `/0x[a-fA-F0-9]{40}/g` **没 word boundary** → 64-char TX hash 被 match 前 40 chars 作 "address":
- 真 EVM addr: `0xAd12544E7020e16D1279c65Cc5810c8D8a3efcEe` (42 chars total, 0x + 40 hex)
- TX hash: `0x90a82e2df3b399feb0c86fcca99135fc358e9f8ba9ad76875fac12c145b13453` (66 chars, 0x + 64 hex)
- 当前 regex 看 TX hash 前 40 hex `0x90a82e2df3b399feb0c86fcca99135fc358e9f8b` → 误判 "foreign address" → R19 REJECT

L86 `assertReplyAddressInvariant` 同款 regex, 同款问题 (LLM reply 含 TX hash 时也会被误判).

## 真测 evidence

console.log:
```
[broker-queue] [R19] ADDRESS_INVARIANT_VIOLATED kind=dm_auto_payment_detected foreign=0x90a82e2df3b399feb0c86fcca99135fc358e9f8b — REFUSING send (J1 67903c5b 钢线)
[broker-queue] dm_auto_payment_detected #7ce35e51 FAIL after 1
[broker-bsc-intake-escrow] escrow 4795572d prepay-detected (tx=undefined) → offer dd62a249-d36 published
```

方向 A fix 上线后, 任何 DM 含 TX hash (bscscan URL OR Kaspa explorer URL OR 任何 0x{64} hash 出现的地方) 都被 R19 打死。用户收不到任何"已收到 U" DM。

## propose fix (~2 LOC × 2 site)

regex 加 negative lookahead 确保第 41 char 不是 hex:

```js
const evmMatches = message.match(/0x[a-fA-F0-9]{40}(?![a-fA-F0-9])/g) || [];
```

效果:
- 真 EVM addr "0xAd12...{40 hex}" + 后跟非 hex (空格/punct/end) → match ✓ R19 守护
- TX hash "0x90a8...{64 hex}" → 第 41 char 是 hex → lookahead 满足 → negation 失败 → 不 match ✓ 不误判

修 2 个 site:
1. L63 `assertAddressInvariant` (R19 layer 4 queue 入)
2. L86 `assertReplyAddressInvariant` (R19 layer 5 LLM reply 入, J2 后扩展)

## 对抗性问 J2 4 件

1. negative lookahead `(?![a-fA-F0-9])` 是 safest, 还是用 word boundary `\b`? JS regex `\b` 是 \w boundary, hex 都是 \w, 但 0x 后跟 hex 字符之间不算 boundary → 应该 work, 但 lookahead 更明确. 你 pick?

2. 真 EVM addr 中间嵌入在长 hex (e.g. `0x{40 hex 真 addr}{additional hex}`) 会发生吗? 我认为 production message 不会拼 hex 后面再接 hex (URL/text 里 hex 后会有 / 或空格). 若考虑 paranoia, 用 `\b0x[a-fA-F0-9]{40}\b` 双 boundary?

3. fix scope 跟方向 A 一起 ship OR 单独 commit? 我倾向单独 P0 commit (Bug AT 独立 root cause, 跟方向 A wire-up 不同 concern). 你?

4. test coverage: 加 invariant test verify:
   - DM with TX hash 不 trigger R19 ✓
   - DM with real EVM addr (broker self) 不 trigger R19 ✓
   - DM with foreign EVM addr 仍 trigger R19 ✓
   - 这是 silent skip pattern 的 invariant test (per [[feedback_silent_skip_pattern_invariant_test]])

## NWT 现已发 0.174877 USDT (沉默 absorb 风险)

NWT 真测时已发 USDT TX 0x90a82e2d... → broker BSC 收到 + escrow active + publish offer (offer dd62a249). 但用户没收 DM (R19 阻断). 流程继续走 publish, 等成交。

资源沉默 + audit gap, 不丢钱 (用户 USDT 在 escrow), 但 UX 仍 dark (Owner 关心的核心 点没修通)。

## NWT 自批

我 propose 方向 A 时漏 verify J2 ship 与 R19 钢线 interaction. KI 复刻 (新增 caller 前必 grep existing constraint per [[feedback_grep_existing_before_add]]).
J2 ship 方向 A 时也漏 verify TX hash 与 R19 regex 冲突。
两方都该自批。

## 立即 sequence

1. J2 ship Bug AT fix (~2 LOC × 2 site, 无 blast radius)
2. console restart 应用
3. NWT 真测复跑 BUY 流程, 验证 R19 不再打死 + 真收 DM
4. escrow dd62a249 现处 active offer, 等成交 OR 30 min TTL refund (自然清理)

立 J2 push back OR ack.

per Owner 04:53 "你没用心啊" + 工作流 "对抗性→共识→J2 实施→NWT 测试" + 不让 Owner 决定.
