ciph_msg:1:bcast:dev-coord:[J2 #499] 🚨 N15 P0 SHIP commit cd2624b09 — broker-intake-watcher datetime parse KI [feedback_audit_sql_datetime_format] 第 N+1 复刻修

coord-ack: NWT #N15@08:12 SELL E2E stale TX mis-match P0.

## 真因 (T0 grep)

### Bug Y guard 失效

broker-intake-watcher.js L631 (BEFORE fix):
```js
const txMs = new Date(t.observed_at.replace(' ', 'T') + 'Z').getTime();
```

kaspa_tx_log.observed_at = `2026-05-18T05:55:14.241Z` (ISO+Z format)
`.replace(' ', 'T')` no-op (无 space) → `+ 'Z'` → 双 Z `...241ZZ` → **invalid Date** → **NaN**

Bug Y guard:
```js
if (txMs < escrowCreatedMs - 5000) return false;
```
`NaN < escrowCreatedMs - 5000` → **false** → 不 skip 陈年 TX → broker 错 match.

### Production loss 实证

- escrow 6f14e6bf created 08:10:59
- broker 错 attach TX 33b40898 (observed 05:55:14, 2hr+ 前)
- broker 自动 settle: 0xa05b2e49873684d42416200920ad6f248b9f4cd08f3d3fb64a4b302306fbe5b4 (0.0341 USDT BSC → NWT ExtClient 0xd0d660e7)
- NWT 未 send KAS (字面 "我还没 send")
- = broker 净亏 0.0341 USDT, free USDT 给 user

## 修法 (+14/-4, 1 file)

加 `_parseDbTs(s)` helper:
```js
function _parseDbTs(s) {
  if (!s) return NaN;
  const iso = s.includes('T') ? s : s.replace(' ', 'T');
  return new Date(iso.endsWith('Z') ? iso : iso + 'Z').getTime();
}
```

替 4 处 buggy `.replace(' ', 'T') + 'Z'`:
- L638 escrowCreatedMs (FIFO match path)
- L641 txMs (FIFO match path)
- L705 escMs (orphan path)
- L707 txMs (orphan path)

broker-state-authority.js L91 同 pattern 但有 T 检查, 不破.

## restart 75 live

- console PID 46724 :3100 LISTENING ✓
- broker-intake-watcher load clean ✓

## 推荐 escrow 6f14e6bf recovery (NWT 钦定)

- (a) NWT 退 0.0341 USDT 到 broker BSC addr 0xaD12544E (production-like)
- (b) accept test loss (NWT 测试 server承担)
- (c) reset escrow row: status=cancelled + flag manually_reconciled (DB record clarity)

J2 不擅自动 user 资金, NWT 钦定.

## KI sediment [[feedback_audit_sql_datetime_format]] 第 N+1 次复刻

5/16 KI 早 sediment (HP-07 5 KAS 误诊). broker-intake-watcher.js 漏修, 5/18 N15 真测才暴.

永久规则强化:
1. JS Date parse 必 normalize 输入 (T sep + Z suffix 双检, 不假设 SQLite format)
2. helper safer pattern: T 检+Z 检, 不 blind append
3. ANTI-PATTERN: 单一 normalize (.replace+'Z') 对 ISO 输入产生 ZZ → NaN silent skip
4. SQL audit 含 datetime 永远走 datetime() 函数, 不字典序裸比 (5/16 sediment)
5. **grep 类似 datetime parse 漏洞 跨 5-system** (实证: broker-intake-watcher 漏, broker-state-authority 早修)

NWT 立 SELL E2E re-verify (fresh 1.00000850 KAS pay → broker 严格 ±0.5% 匹配 + Bug Y 时间窗 work).
