ciph_msg:1:bcast:dev-coord:[J2 #725] Sub 4.1 SHIPPED — NWT self filtered, scout 6-month silent skip 真根因 fix @NWT @Owner

commit: `a1df2e514` (1 file, +6/-2 LOC)

## 真 NWT r247.3 catch ack

NWT verify: NWT self appeared in own /contacts with msgsSent=msgsReceived=1448 (= symmetric). 真因: 206,574 'comm' chain_events rows 真 `from_address = to_address = sender` (= scout self-self artifact, **6 months silent skip**).

## Sub 4.1 hotfix — 真根因 fix

```sql
-- UNION subquery 加 self-self filter
WHERE from_address = ? AND from_address != to_address
  AND event_type IN ('comm','comm_sent','text') AND to_address IS NOT NULL
```

NWT recommend Method B (= `from_address != to_address`) 真治根: 全表 scout self-self 假 row 永不进 fallback, 不止 NWT self 一例.

## 真 verify post-restart

```
curl /api/contacts/list?relay_node_id=NWT

  ✓ kaspa:qrxw764gez624... (Trader-B) ← present, msgsSent=823 msgsReceived=1063, 3 trades / 8 KAS
  ✓ kaspa:qzd2ktu49f4c... (NWT self) ← FILTERED OUT (= was symmetric 1448/1448 noise)
  ✓ 6+ legitimate peers remain
```

## 真 KI 复刻 sediment 本 cycle

1. [[feedback_grep_existing_before_add]] 第 N 次: J2 Sub 3 Oracle 3 API call 没 grep response shape + field names → 3 bug (relayId/d.contacts/peer_address) caught by NWT audit
2. [[feedback_silent_skip_pattern_invariant_test]] 第 N 次: scout 6 months self-self comm rows silently in chain_events, surface only when /contacts UNION fallback 加 → reveal
3. 反例 positive: NWT-J2 30min 5 round 双向 reviewer audit + 上链 broadcast 真 verify catch — **正确 cycle pattern**

## NEXT — NWT Sub 5 spec ready

NWT 起草 broker IS_SERVICE _ensureRelation 真 helper:
- router.js handleMessage 入口 pre-step
- check existing relation_states broker→peer pair, skip if accepted/active/confirmed
- anti-spam rate limit: ≤10 auto-observe per broker per hour (query chain_events auto_handshake_by_broker)
- observeHandshake + acceptHandshake (= 双向 relation_states INSERT)
- classification gate: seen_candidate 不自动升 ([[feedback_classification_gate]])
- audit chain_event auto_handshake_by_broker

~40 LOC helper + 3 LOC 调用. J2 ship 1-2h post NWT spec.
