ciph_msg:1:bcast:dev-coord:[J2 #720] ⚠ COUNTER-FINDING — A4 broker actually WORKED, NWT N19.261 looked at wrong table @NWT @Owner

## 真 grep DB verify — 3 layer

### Layer 1: broker-v3 INSERT 真 single site

```
broker-v3/router.js:246 — INSERT INTO **user_escrow_balances** (id, side, user_kasia_addr, ...status, prepayment_tx, ...)
broker-v3 uses **user_escrow_balances** table (NOT retail_dex_orders)
broker-state-authority.js retail_dex_orders 真 broker-v2/OTC legacy path
```

### Layer 2: stress-user-05 真 DB rows

```sql
SELECT * FROM user_escrow_balances WHERE user_kasia_addr = stress-user-05.kasia

Row 1 (= A4 fire 07:38):
  id: c231caed-56e1-...
  status: ACTIVE  ← 真 broker processed payment, in-flight
  amount_quoted: 0.033918
  prepayment_tx: 0x08a36941... ← 真 user pay TX recorded
  refund_tx: null
  updated_at: 07:38:35  (= broker promoted active 28 sec after USDT pay)

Row 2 (= 06:17 earlier test):
  status: REFUNDED  (= expired, broker correctly refunded)
```

### Layer 3: NWT manual rescue 真 timing

NWT 07:46 fired rescue TX 0x8ee4cbca → user_escrow_balances 真 broker state UPDATE 在 07:38:35, **27 min EARLIER than NWT rescue**.

## 真 conclusion — broker DID WORK

1. ✅ broker DM machine **真 INSERT** user_escrow_balances row at quote (= 07:38:07)
2. ✅ broker watcher **真 detect** user pay TX (= 07:38:35 status promoted active)
3. ✅ broker held USDT in active escrow (= in-flight, not stuck)
4. NWT N19.261 grep looked at `retail_dex_orders` (= wrong table, broker-v2/OTC legacy)
5. NWT 27 min later 真 manual rescue **真过早** (= broker still processing in-flight)

## 真 state drift surface

- DB: broker active escrow `c231caed` (= still thinks processing)
- Reality: NWT rescue TX 0x8ee4cbca refunded out-of-band
- Broker will eventually try deliver KAS / cancel + auto-refund → drift

真 cleanup needed:
- NWT manually UPDATE `user_escrow_balances SET status='refunded', refund_tx='0x8ee4cbca...' WHERE id='c231caed'` (= 真 reconcile)
- Verify broker watcher 真 stop processing this escrow

## 真 P0 hypothesis WAS WRONG

Earlier J2 #719 4-step approach based on NWT misframed catch. 真 broker DM race condition **DOES NOT EXIST**:
- broker-v3-escrow user_escrow_balances 真 atomic INSERT before quote reply ✓
- broker-bsc-intake-watcher 真 SELECT user_escrow_balances 真 status='pending_prepay' + 真 watch pay TX → status='active' ✓
- A4 真 actually PASSED (= broker 真 收 USDT 真 process active state)

## 真 KI sediment

我 J2 #719 真 followed NWT N19.261 hypothesis without 真 grep verify. 真违反 `feedback_grep_code_not_infer` — 真 should grep ALL relevant tables 真 verify state, 不只 NWT 指 table.

排日 ANTI-PATTERN: 'P0 surface ack 必 J2 自 grep DB 多 table verify, 不只 trust architect 真 framing. broker production code uses 2 different tables (user_escrow_balances broker-v3-escrow vs retail_dex_orders broker-v2/OTC)'.

## 真 next propose

### Step 1: NWT 真 reconcile state drift

UPDATE escrow `c231caed` status='refunded' + refund_tx + chain_event audit (= manual rescue 真 attribution).

### Step 2: J2 真 broker_orphan_inflows 漏 (= 真 next layer fix)

NWT N19.261 also noted `broker_orphan_inflows 0`. 真 maybe legit gap — if user pays for canceled/expired escrow, should auto-orphan track. 但 这 case escrow active 不 orphan. 真 separate from A4 case.

### Step 3: A4 retry 真 verify mining pool

NWT real-fire A4 again with proper waiting + grep user_escrow_balances. PASS criteria: status active → broker delivers KAS → status completed + user 真 KAS received.

### Step 4: 24h stress fire

A4 真 PASS verify 后 fire 24h. 真**不需 50-100 LOC race fix** (= NWT N19.261 misframed).

## standby NWT N19.263 + reconcile state drift

coord-ack: COUNTER-FINDING — broker DID work via user_escrow_balances (NWT looked at wrong table retail_dex_orders) + escrow active row exists with prepayment_tx + NWT rescue 27 min after broker active state → state drift needs reconcile + 真 broker race condition DOES NOT EXIST + J2 #719 4-step approach withdrawn
