ciph_msg:1:bcast:dev-coord:[NWT #N19.41 🎯 @J2 @Owner — 13 fail 深挖 报告: 3 类真因 (timeout + 测试数据沉积 + imperative runner trace bug)]

Owner 5/19 16:02 钦定 "深挖! 深查! 然后分析原因和问题". NWT 静态 + 动态 dig surface 3 类真因.

## 13 fail (09:00 cron) → 6 fail (09:08 retry) — 系统 stabilizing

KI 23 stagger boot 加载后, 7 cases 自然恢复 (timeout related). 6 cases persistent.

## 类 1: HTTP timeout (4 cases, console event loop slow)

失败 trace 共同 pattern:
```
Step N http_post — Latency: 10009ms
reply: > The operation was aborted due to timeout
http_status_equals: HTTP undefined (want 400); error=The operation was aborted due to timeout
```

- exchange_accept_transitions_matched (10s timeout step 2)
- exchange_cancel_releases_fund_lock (10s timeout multi)
- exchange_payment_transitions_verifying
- exchange_publish_creates_offer

真因: console event loop slow 因 (a) KI 23 8 relay cron storm pre-stagger fix (b) Bettor TN12 rusty-kaspa 8.7GB RAM hog CPU contention.

fix: 已 ship (KI 23 stagger 567fb559b7 + 等 Bettor TN12 sync 完). 自愈类.

## 类 2: 测试数据沉积 + UNIQUE constraint cascading fail (5 cases) — KI 24

**关键发现**: 5 个 exchange domain test 全用 hardcoded broadcast_tx_id 单字母 repeat:

| case | broadcast_tx_id | 残留 row date |
|---|---|---|
| exchange_accept_transitions_matched | `'a'.repeat(64)` | unknown |
| exchange_payment_transitions_verifying | `'b'.repeat(64)` | unknown |
| exchange_cancel_releases_fund_lock | `'c'.repeat(64)` | unknown |
| exchange_dispute_resolve_concede | `'d'.repeat(64)` | **04:01 (test-dispute-mpc3vi8h status=disputed 残留)** |
| n13_awaiting_manual_confirm_update_works | repeat (need verify) | unknown |

`UNIQUE(broadcast_tx_id, message_index)` constraint:
- Run 1 INSERT success → cleanup DELETE → row gone
- Run N mid-fail (assertion failure) → cleanup 不 run → row stays
- Run N+1 INSERT 撞 UNIQUE constraint → throws → exec_sql action catch → return {ok:false}
- Trace shows step "exec_sql" silent skip (?? trace 我看到的可能 PASS, 需 J2 verify exec_sql 真 throw)
- Subsequent http_post 拿 stale ID → 404 "Offer not found" → assertion fail

NWT 实证: 直 INSERT `'d'.repeat(64)` → `UNIQUE constraint failed: exchange_offers.broadcast_tx_id, exchange_offers.message_index`. SELECT 之后 NOT FOUND. 

修法 propose:
- (a) 5 个 case 改用 random broadcast_tx_id: `Array(64).fill(0).map(()=>Math.floor(Math.random()*16).toString(16)).join('')`
- (b) cleanup 残留 row: DELETE FROM exchange_offers WHERE id = 'test-dispute-mpc3vi8h' AND created_at < '2026-05-19 06:00'
- (c) exec_sql action 加 explicit ON CONFLICT IGNORE / DELETE before INSERT pattern (但 改 runner 影响 70+ cases)

NWT 倾 (a)+(b) — random tx + cleanup, 不动 runner.

## 类 3: NWT runner.mjs patch bug — imperative case 不写 trace file (4 cases)

NWT 79172e1591 patch 加 imperative async run() support. 但 `return result` 跳过 trace file write logic in later runCase body.

imperative cases:
- autotaker_tier_v4_amount_caps (broker domain)
- kas_price_multi_source_fallback (exchange)
- publish_dispatches_autotaker_n19_27 (exchange)
- 4 Playwright console_ui_* (system)
- n10_router_idempotent_skip_return (broker)

failure 报告: 09:00 cron 全 FAIL, 但 trace file 无 update (stale PASS file from 06:32). Real failure reason unknown.

修法 (~5 LOC): runner.mjs patch 调 writeTrace() before return:
```js
if (typeof testCase.run === 'function') {
  try { ... } catch { ... }
  result.ended_at = new Date().toISOString();
  await writeTrace(result);  // ← 加这行
  return result;
}
```

NWT 自责 patch 漏 — 立 fire fix.

## summary

| 类 | cases 数 | 根因 | 状态 |
|---|---|---|---|
| 1 HTTP timeout | 4 | console event loop slow | 自愈 (KI 23 fix + testnet sync 完) |
| 2 UNIQUE constraint cascading | 5 | test 残留 row + hardcoded broadcast_tx_id | propose (a)+(b) NWT/J2 ship |
| 3 NWT runner patch | 5 | trace file missing for imperative | NWT 立 fire (~5 LOC) |

## fire 顺序 propose

1. NWT 立 fix runner.mjs trace bug (~5 LOC, 5 min)
2. NWT 立 cleanup 残留 test rows (1 SQL DELETE, 1 min)
3. NWT 立 fix 5 cases random broadcast_tx_id (~15 LOC × 5, 15 min)
4. 等 testnet sync done + 重 cron run → 13→0 fail

NWT 立 fire 1+2+3, ETA ~20 min ship.
