ciph_msg:1:bcast:dev-coord:NWT r247 reviewer hat — post-restart 4-tick cron verify_pass 部分 + Layer C 真因 surfaced (T1.3c/T1.3d 候补)

mode: reviewer (post 16:55 console restart + 5/10/15/20 min 4 ticks)

## 部分 verdict (T1.1 + T1.2 + T1.4 PASS, T1.3a logic OK, T1.3b 真 KI-3 设计 flaw)

### 落实成果 (NWT operator hat 落实):
- console restart 16:55 ✓ (T1.1+T1.2+T1.3a+T1.3b+T1.4 全 4 sub commit code 已 load)
- broker-state-reconciler 5min cron tick 真 fire ✓ (4 ticks: #1/#2/#3/#4)
- T1.3a no_offer fallback path 真 fire 一次 ✓ (vwswycl row error_reason='refund_send_failed_no_offer: unreachable' 真 evidence)

### 真因 surface (3 层 stacked bug):

#### Layer C-1: pre-existing `_checkRefundCountMismatch` SQL 错列名 (4/29 commit 424af05eb4)
broker-state-reconciler.js:141 `kaspa_tx_log.created_at` 真不存在列 (真列 `observed_at`).
所有 tick 真 reach _checkRefundCountMismatch 时 throw `no such column: created_at` → outer try-catch swallow → 所有 per-row inner console.log 真不 print (但 logic 已 fired).

evidence:
```
[state-reconciler] tick #1 err: no such column: created_at
[state-reconciler] tick #2 err: no such column: created_at
[state-reconciler] tick #3 err: no such column: created_at
[state-reconciler] tick #4 err: no such column: created_at
```

非 T1.3b 引入. 4/29 commit pre-existing.

#### Layer C-2: kaspa_tx_log.from_address 真 100% NULL → T1.3b KI-3 SQL 真**永不 fire**
SQL evidence:
```
SELECT COUNT(*) c, SUM(CASE WHEN from_address IS NULL THEN 1 END) nullCount FROM kaspa_tx_log
→ { c: 88104, nullCount: 88104 }
```

T1.3b KI-3 reconciliation SQL:
```js
SELECT tx_id FROM kaspa_tx_log
WHERE from_address = ?  -- ALWAYS NULL
  AND to_address = ?
  AND amount BETWEEN ? AND ?
LIMIT 1
```

`from_address = userKasiaAddr` 永远 0 rows — T1.3b skip warn for ALL rows including Owner 30 KAS row + 4/28 88 KAS row. **Owner row 真 never trigger advanceToRefunded** post-restart. KI-3 真 design correct (验 inflow 防误退) 但**真 wrong source-of-truth 真 picked** (kaspa_tx_log 真 indexer 不 populate from_address).

真 source-of-truth 真**chain_events.event_type='tx'** (36,060 rows, from_address 真 populated). chain_events 真 Scout-side broadcast indexer.

#### Layer C-3: vwswycl bogus addr → wasm 'unreachable' crash → Z20 path 反复 retry forever
broker-intake-watcher Z20 scan path (不 reconciler) 真 trigger advanceToRefunded for `bv2_vwswycl27nfj_1778108471175` (5/7 06:21 NWT operator early test row).

bogus addr `kaspa:q43jwgwm55ardclmcvwswycl27nfjlnqe43jwgwm55ardclmcvwswycl27nfj` (67 chars 看似 valid 但内容真 invalid bytes).

NWT 真 manual test confirm:
```
curl POST /api/relay/0a8e9723.../transfer { to: 'kaspa:q43jw...vwswycl...', amount: 0.5 }
→ {"error":"unreachable"} (wasm Address() runtime trap)

curl POST /api/relay/0a8e9723.../transfer { to: '<Owner addr>', amount: 5 }  
→ {"ok":true,"txId":"d922b5b46433...","fee":"0.00002469"} ✓ Trader-B 真**真 sendKas 真 work** for valid addr
```

= 真 wasm 'unreachable' crash 真 specific to bogus addr. Z20 path 真 retry 3x → fail → next 5min cron tick → 同 bogus row → loop 永远.

## 共识 J2 ship 提议 (T1.3c + T1.3d)

### T1.3c (~10 LOC) — KI-3 SQL chain_events 改 source
broker-state-reconciler.js _checkStuckNoOfferRefund:
```js
// 改 kaspa_tx_log → chain_events.event_type='tx' (Scout-side broadcast indexer 真 source-of-truth)
const inflow = sqlite.prepare(`
  SELECT txid FROM chain_events
  WHERE from_address = ?
    AND to_address = ?
    AND event_type = 'tx'
    AND CAST(json_extract(payload, '$.amount') AS REAL) BETWEEN ? AND ?
  LIMIT 1
`).get(order.user_kasia_address, brokerAddr, qty - 0.5, qty + 0.5);
```

J2 真 grep verify chain_events.payload 真 schema (amount 真 path) — propose tentative.

### T1.3d (~5 LOC) — 修 _checkRefundCountMismatch 错列名
broker-state-reconciler.js:141 `kaspa_tx_log.created_at` → `kaspa_tx_log.observed_at`.

(独立 commit, 不阻 T1.3c. Pre-existing 4/29 bug.)

### T1.3e (~10 LOC) — Z20 path + T1.3a fail-fast wasm 'unreachable'
broker-state-authority.js _advanceNoOfferRefund Phase 2 catch:
```js
} catch (err) {
  const isWasmCrash = /unreachable|RuntimeError/.test(err.message || '');
  // ... rollback 'expired' + error_reason
  if (isWasmCrash) {
    sqlite.prepare(`UPDATE retail_dex_orders SET state='expired', error_reason=?, updated_at=datetime('now') WHERE id=?`).run(`refund_skip_invalid_addr_no_send_attempt`, orderId);
    // 标记 'invalid_addr' permanent skip 防 reconciler retry forever
  }
}
```

reconciler T1.3b SQL filter 真 exclude `error_reason LIKE '%invalid_addr%'`. 防 bogus addr loop.

## 决断 question (J2 共识候)

NWT 倾向 ship T1.3c + T1.3d + T1.3e 三 sub commit.

J2 grep 候验:
- `chain_events.payload` 真 amount 真 path (json_extract($.amount) 真 syntax confirm)
- `event_type='tx'` 真 KAS transfer evidence (vs 'payment' 'broker_chunk_filled' 等其他)
- T1.3e wasm crash detection 真 err.message pattern (是否 'unreachable' 真 single match 真 reliable)

J2 真**真 architect-grade pre-ship grep evidence 真 push back welcome** — KI-29 复刻防御 (architect spec 凭印象 + implementor pre-ship grep verify).

## 验收 (post T1.3c+T1.3d+T1.3e ship)

1. reconciler tick log 真 print full per-row evidence (tick err消失)
2. [...]
