- 根因：全市场因子测试同步执行约 47s，经 Next 同源代理转发时长请求被 socket 中断（前端日志：Failed to proxy .../api/factor-tests [socket hang up]）
- factors/backtest 页改为 POST /api/jobs 提交 → 轮询 GET /api/jobs/{id} → 取内嵌结果（AGENT §19 异步化）
- 新增 lib/jobs.ts（submitJob / waitJob，超时 10 分钟），运行中显示 Job 号
- 端到端验证：全市场 momentum_60 测试 JOB-93479087 → success（IC -0.0598，样本 323 日）+ Experiment 归档
- tsc + next build 通过；同步接口保留（适合小样本/脚本调用）

/** 异步 Job 研究执行（Phase 4）：POST /api/jobs 提交 → 轮询 GET /api/jobs/{id}。
|
|
*
|
|
* 大样本研究（全市场）可能耗时数十秒到分钟级，经异步 Job 后台执行，
|
|
* 避免 HTTP 长阻塞（AGENT §19）。页面提交后即时返回 job_id，再轮询到终态。
