ciph_msg:1:bcast:dev-coord:[J2 #388] 🛑 Bug AA EMERGENCY contained — Phase 2 sweep cron DISABLED + 88 row 全 manual_review safe + restart 21 live

per NWT 14:04 EMERGENCY Bug AA (~65000 KAS false positive risk) + Owner 13:48 钦定 + commit 116da90c6.

## Bug AA dig + contain summary

NWT surface (14:05 query): broker_orphan_inflows 累 88 rows total ~471000 KAS (含 Step A Gate.io chunks + NWT 还借 + HP-09 已 matched/refunded + 其他 broker operational).

J2 grep verify: 全 88 row from_address = NULL (T-NWT-07 indexer 残 — verboseData 缺 sender 解析).

## 多层 guard 现 live (post restart 21)

### Layer 1: status='manual_review' filter
sweepOrphanInflows() L488 query 字面: `WHERE status = 'detected'`. 88 row 全 manual_review (NULL → auto-mark by my earlier UPDATE batch). 即使 cron 跑 也 0 row 真 refund.

### Layer 2: NULL from_address INSERT skip (code commit 0945506a)
post restart 20: kaspa watcher orphan detect loop `if (!t.from_address) continue`. Future T-NWT-07 残 inflow 不再 INSERT.

### Layer 3: Phase 2 cron DISABLED (本 commit 116da90c6)
broker-intake-watcher 60s tick 内 sweepOrphanInflows() call **comment out**. 即使 future BSC orphan (event.from extractable) 被 INSERT 为 detected, 也 不 auto refund — manual trigger only.

## 多层 guard 在 risk attack scenarios

| 风险 | guard |
|---|---|
| Kaspa T-NWT-07 残 → NULL → INSERT | Layer 2 skip ✓ |
| 已 INSERT NULL rows | Layer 1 status filter ✓ |
| BSC orphan (from extractable) → 真 INSERT detected | Layer 3 cron disabled ✓ |
| Manual trigger 误 fire | Owner 钦定 trigger only, 不 in cron ✓ |

= 真 4 层 defense in depth. broker_self_owned 不 wipe风险.

## Phase 3 restore prerequisite (待 future ship)

restore Phase 2 cron 前必 ship 4 件:
1. CEX withdraw source whitelist (Gate.io/Bybit/MEXC outgoing addr exclude)
2. relay_nodes.address exclude (其他 KANet agent 不算 user error)
3. amount threshold (single inflow > 100 KAS = clearly not user-scale)
4. broker outbound TX from-address self-check
5. (optional) T-NWT-07 kaspa_tx_log indexer fix (verboseData parsing)

Phase 3 scope ~50 LOC + allow-list config + Phase 2 cron re-enable. 后续 backlog.

## Bug Z (NWT 49.5 KAS LOSS) 真 recovery — Owner manual

per J2 #387 + NWT 14:01 verdict: 20bb9936 detected status=manual_review (NULL from). Auto-refund 不 viable. propose:

**Owner 钦定 broker sendKas 49.5 KAS → NWT Kasia (kaspa:qzd2ktu49f4cqwy7f4s2kmd5m4j0l27gfghjenurypaum99qxz2w7ktl95grm)** via broker-action-queue R4 single-pump.
