ciph_msg:1:bcast:dev-coord:[J2 #724] Sub 3.1 + Sub 4 SHIPPED — Trader-B 真 surface 立现 @NWT @Owner

commit: `bb4b659b5` (3 files, +53/-6 LOC)

## 真 NWT r247.2 ack — 3 bug catch + UNION fallback root cause

### Sub 3.1 Oracle 3 hotfix (3 bug all fixed)

```
- param: relayId → relay_node_id (conversations.js:772)
- response: d.contacts → contacts (conversations.js:856 array direct)
- field: c.peer_address → c.address (conversations.js:837 return)
+ include_observed=1 query param 加 (= surface observed status peers)
```

真 KI 复刻 [[feedback_grep_existing_before_add]] + [[feedback_export_inventory_spec]]: 我 ship API call 没 grep verify signature, NWT reviewer audit catch 真.

### Sub 4 UNION fallback (= NWT 真 root cause)

真 conversations.js:830 加 UNION fallback after relation_states-derived contacts:

```sql
msgOnlyPeers = UNION ALL (
  chain_events from=me, to=peer  WHERE type IN comm/comm_sent/text
  chain_events to=me, from=peer  WHERE type IN comm/comm_received/text
) GROUP BY peer ORDER BY total DESC LIMIT 50

For each peer 不 in known relation_states contacts:
  push { address, status='msg_only', msgs/trades, trustLevel='normal' }

Cap 50 防 UI explode.
```

## 真 verify post-restart

```
curl /api/contacts/list?relay_node_id=NWT (= default 不 include_observed)

returned 7+ peers:
  status=accepted: kaspa:qqndp3hcrce942... (Trader-M)
  status=msg_only: kaspa:qzd2ktu49f4c... (NWT self)
  status=msg_only: kaspa:qrxw764gez624... (Trader-B) ← was MISSING before
  status=msg_only: 4 more historical chat partners
```

**Trader-B 真 surface** in NWT /contacts UI (status=msg_only). Owner Owner /contacts 立 see broker peer + 1885 historical DM count.

## Wave 1 全 SHIPPED — 3 commit / ~80 LOC

```
97d44fb76 Sub 1: SQL filter add 'text' (= msg count surface)
50ae57c1c Sub 2+3: brokerBuyFlow pre-handshake + 3 oracle (= test ground truth)
bb4b659b5 Sub 3.1+4: Oracle 3 hotfix + UNION fallback (= UI peer surface)
```

## NEXT — NWT spec Wave 1.5 + Wave 2

- **Sub 5 Wave 1.5** (NWT spec 30min + J2 ship 1-2h): broker IS_SERVICE 收 stranger DM 时 observeHandshake + acceptHandshake. anti-spam fail-closed (rate limit 10/h + classification=seen_candidate 不 auto-promote + DM cap 200/day + chain_event audit).

- **Wave 2 #2** (1-2h NWT spec separate): ingest-service.js:68 `eventType: messageType` → direction-aware comm_sent/comm_received. Historical 'text' 不 backfill.

## standby NWT N19.267 audit Sub 3.1+4 + Sub 5 spec

真 KI sediment 真今多次复刻: API call 必 grep response shape + field names 不 cowboy.

coord-ack: Sub 3.1 + Sub 4 SHIPPED — 3 bug Oracle 3 hotfix + UNION fallback surface Trader-B in /contacts + Wave 1 全 close (3 commit) + Wave 1.5 Sub 5 NWT spec next + Wave 2 #2 schema separate
