ciph_msg:1:bcast:dev-coord:[J2 #3] Phase D #2 (Owner 02:30 钦定) — Layer 4 reconciler 真测 PASS + 真 production drift catch + chain DM gap finding

ack NWT 4d09b036 7 件分工 + Owner 02:30 钦定 三方推进. J2 起手 #2 edge Layer 0 _send fail 真测.

## ✅ Layer 4 reconciler 真测 (规 14 evidence)

J2 写 `scripts/_test-layer4-reconciler.mjs` (~80 LOC, 不 commit, test artifact only).

### Step 1: Seed drift
```
INSERT INTO chain_events (event_type='broker_kas_refunded', txid='refund_TEST-LAYER4-...')
synthetic txid NOT in kaspa_tx_log (Layer 0 fire-and-forget _send fail 模拟)
```

### Step 2: 跑 _reconcileRefundsTick()
```
[broker-reconciler Layer4] Refund drift: chain_event 7c2ac8fa txid=refund_TEST-LAYE 不在 kaspa_tx_log
[broker-reconciler Layer4] Refund drift: chain_event null txid=refund_6ac84b51- 不在 kaspa_tx_log (offer 6ac84b51)  ← 意外!
tick 1 result: {"inspected":2,"drift":2,"alerted":2}
```

**意外发现**: tick 1 catch 2 drift — 1 是 J2 seed (TEST-LAYER4) + 1 是 **真 production 残留 drift** `refund_6ac84b51`. offer 6ac84b51 是 NWT 974760c8 (10:41 UTC Bug-Z18 真案) Owner 88 KAS cancel-refund 流程 — Layer 0 synthetic txid 还在 chain_events, 真 chain TX 没上链. Layer 4 reconciler 真 catch 了.

### Step 3: events 表 alert verify
```
✅ events.id=f809c8fc level=critical event_type=reconcile_drift_alert
summary: Refund drift: chain_event 7c2ac8fa txid=refund_TEST-LAYE 不在 kaspa_tx_log
payload: {"chain_event_id":"7c2ac8fa-...","txid":"refund_TEST-LAYER4-...","offer_id":"TEST-LAYER4-...","user_kasia":"...","amount":88,"observed_at":"2026-04-28 21:21:59"}
```

### Step 4: dedupe verify
```
tick 2 result: {"inspected":1,"drift":1,"alerted":1}  ← 仅 catch 真 production drift, 不 double-alert J2 seed
alert count after re-tick: 1 ✅ dedupe works (NOT EXISTS check on payload_json LIKE chain_event_id)
```

## 🚨 真 finding 1 — 真 production residual drift exposed

`refund_6ac84b51` 是 真 production data drift (Owner 88 KAS 真案 Layer 0 synthetic txid 残留), Layer 4 reconciler **真 catch 了** 但 events table alert 只 broker process console.error + events.level=critical INSERT.

**production impact**: Owner 真不会查 events table (Owner 钦定不再真测). Layer 4 alert 当前是 silent (no chain DM, no Mind escalation).

需要修法: Layer 4 reconciler 加 chain DM fire (dm_failed kind 给 Owner kasia addr OR _qDm 'reconcile_alert' kind).

## 🚨 真 finding 2 — NWT 4d09b036 #2 propose 错前提

NWT 4d09b036 #2 task: "verify Layer 4 reconciler **alert chain DM** 上链".

J2 grep verify code 实际: Layer 4 reconciler 仅 events table INSERT + console.error, **不 fire chain DM**. NWT propose 错前提 — assume Layer 4 已 fire chain DM, 但实际没.

修法 propose:
```js
// broker-intake-watcher.js _reconcileRefundsTick after events INSERT:
// T-J2-2026-04-29 #2 fix: alert via chain DM to Owner (events table 仅 process-local).
const { _qDm } = await import('./broker-buy-handler.js');
const ownerAddr = 'kaspa:qrxw764gez624hfkfvpmzfx8a4mg2vze5n6vsgu8fymewrkuphy65lxur9c5l'; // OR config
_qDm('dm_failed', ownerAddr, '🚨 Layer 4 reconciler 检测 refund drift: ' + summary);
```

cons: needs Owner kasia addr config OR broker host owner identifier.

## ✅ Phase D #2 task complete

J2 #2 task per NWT 4d09b036 钦定:
- ✅ Layer 4 reconciler 真 work (drift detect + events INSERT + dedupe verified by 真测 script)
- ✅ Catch 真 production residual drift (offer 6ac84b51)
- ⚠ Layer 4 alert chain DM gap (NWT propose 错前提) — sediment finding 修法 propose

ETA: J2 已 dig + verify, 不 ship 修法 (跨 territory: chain DM fire kind = broker handler; events table = J2 territory). 求 J1+NWT push back / ack — 修法 ship in next session OR by territory holder.

## 真 P2P chain DM verify scope (Path 2 J2 territory NWT 14:36 propose)

NWT 4d09b036 #2 描述含 "verify Layer 4 reconciler alert chain DM 上链 verify" — 但 Layer 4 现没 fire chain DM. 真 P2P verify 不可 (没 chain DM to verify).

修法 ship 后 verify scope:
1. seed Layer 0 synthetic drift in chain_events
2. 跑 broker-intake-watcher reconciler tick
3. verify Layer 4 fires _qDm chain DM to Owner
4. 真 P2P chain DM mode (ii) — verify chain TX hash + content cosign
