 Settings reads are side-effect free: `GET /settings/llm` and `GET /settings/data-sources` never create `agent/.env`, and they only return project-relative paths. Settings reads and writes can expose credential state or update credentials/runtime environment, so they require `API_AUTH_KEY` when configured. If `API_AUTH_KEY` is unset for dev mode, settings access is accepted only from loopback clients.
 
+### Scheduled research
+
+Run a research prompt or backtest on a repeating schedule. The background executor is **off by default** — start the server with `VIBE_TRADING_ENABLE_SCHEDULER=1` to enable it:
+
+```bash
+VIBE_TRADING_ENABLE_SCHEDULER=1 vibe-trading serve --port 8899
+```
+
+Then create jobs over REST. `schedule` is either a bare integer (interval in **milliseconds**) or a 5-field cron expression (`min hour dom mon dow`):
+
+```bash
+# every 6 hours (cron)
+curl -X POST http://localhost:8899/scheduled-runs \
+  -H "Content-Type: application/json" \
+  -d '{"prompt":"Scan CSI300 for momentum breakouts and backtest the top 5","schedule":"0 */6 * * *"}'
+
+# list / cancel
+curl http://localhost:8899/scheduled-runs
+curl -X DELETE http://localhost:8899/scheduled-runs/<job_id>
+```
+
+Each fire runs the `prompt` through a fresh agent session (optional backtest parameters go in `config`), and jobs persist under `~/.vibe-trading/` so they survive restarts. Without the flag, the `/scheduled-runs` endpoints still record jobs but nothing fires. Add `-H "Authorization: Bearer <key>"` to each call when `API_AUTH_KEY` is set.

 قراءات Settings بلا آثار جانبية: لا تنشئ `GET /settings/llm` ولا `GET /settings/data-sources` ملف `agent/.env`، ولا تعيدان إلا مسارات نسبية للمشروع. قد تكشف قراءات وكتابات Settings حالة بيانات الاعتماد أو تحدث بيانات الاعتماد/بيئة التشغيل، لذلك تتطلب `API_AUTH_KEY` عند ضبطه. إذا كان `API_AUTH_KEY` غير مضبوط في وضع التطوير، فلا يقبل الوصول إلى Settings إلا من عملاء loopback.
 
+### البحث المجدول (Scheduled research)
+
+شغّل prompt بحثي أو backtest وفق جدول متكرر. المنفّذ الخلفي **معطّل افتراضياً** — شغّل الخادم بـ `VIBE_TRADING_ENABLE_SCHEDULER=1` لتفعيله:
+
+```bash
+VIBE_TRADING_ENABLE_SCHEDULER=1 vibe-trading serve --port 8899
+```
+
+ثم أنشئ المهام عبر REST. الحقل `schedule` إما عدد صحيح بسيط (الفاصل بـ**المللي ثانية**) أو تعبير cron من 5 حقول (`دقيقة ساعة يوم شهر يوم-الأسبوع`):
+
+```bash
+# كل 6 ساعات (cron)
+curl -X POST http://localhost:8899/scheduled-runs \
+  -H "Content-Type: application/json" \
+  -d '{"prompt":"Scan CSI300 for momentum breakouts and backtest the top 5","schedule":"0 */6 * * *"}'
+
+# السرد / الإلغاء
+curl http://localhost:8899/scheduled-runs
+curl -X DELETE http://localhost:8899/scheduled-runs/<job_id>
+```
+
+كل تشغيل ينفّذ `prompt` في جلسة agent جديدة (تُوضع معلمات backtest الاختيارية في `config`)، وتُحفظ المهام تحت `~/.vibe-trading/` فتبقى بعد إعادة التشغيل. بدون هذه الراية، تسجّل نقاط `/scheduled-runs` المهام لكن لا يُطلق شيء. أضف `-H "Authorization: Bearer <key>"` لكل طلب عند ضبط `API_AUTH_KEY`.

 Settings reads は side-effect free です。`GET /settings/llm` と `GET /settings/data-sources` は `agent/.env` を作成せず、project-relative paths だけを返します。Settings の読み書きは credential state の公開や credentials/runtime environment の更新を伴うため、設定済みの場合は `API_AUTH_KEY` が必要です。dev mode で `API_AUTH_KEY` が未設定の場合、settings access は loopback clients からのみ受け付けます。

 Settings read는 side effect가 없습니다. `GET /settings/llm`과 `GET /settings/data-sources`는 `agent/.env`를 만들지 않으며 project-relative path만 반환합니다. Settings read/write는 credential state를 노출하거나 credential/runtime environment를 업데이트할 수 있으므로 `API_AUTH_KEY`가 설정되어 있으면 인증이 필요합니다. dev mode에서 `API_AUTH_KEY`가 설정되지 않은 경우 settings access는 loopback client에서만 허용됩니다.
 
+### Scheduled research (예약 리서치)
+
+리서치 prompt나 backtest를 반복 일정으로 실행합니다. 백그라운드 executor는 **기본적으로 꺼져 있습니다** — `VIBE_TRADING_ENABLE_SCHEDULER=1`로 server를 시작하면 활성화됩니다:
+
+```bash
+VIBE_TRADING_ENABLE_SCHEDULER=1 vibe-trading serve --port 8899
+```
+
+그런 다음 REST로 작업을 생성합니다. `schedule`은 단순 정수(간격, 단위 **밀리초**)이거나 5필드 cron 표현식(`분 시 일 월 요일`)입니다:
+
+```bash
+# 6시간마다 (cron)
+curl -X POST http://localhost:8899/scheduled-runs \
+  -H "Content-Type: application/json" \
+  -d '{"prompt":"Scan CSI300 for momentum breakouts and backtest the top 5","schedule":"0 */6 * * *"}'
+
+# 목록 / 취소
+curl http://localhost:8899/scheduled-runs
+curl -X DELETE http://localhost:8899/scheduled-runs/<job_id>
+```
+
+각 실행은 새 agent session에서 `prompt`를 실행하며(선택적 backtest 파라미터는 `config`에 넣습니다), 작업은 `~/.vibe-trading/`에 저장되어 재시작 후에도 유지됩니다. 이 플래그가 없으면 `/scheduled-runs` endpoint는 작업을 기록하지만 실행되지는 않습니다. `API_AUTH_KEY`가 설정된 경우 각 호출에 `-H "Authorization: Bearer <key>"`를 추가하세요.

 Settings 读取无副作用：`GET /settings/llm` 和 `GET /settings/data-sources` 永远不会创建 `agent/.env`，并且只返回项目相对路径。Settings 读写可能暴露凭据状态或更新凭据/运行时环境，因此在配置了 `API_AUTH_KEY` 时会要求认证。如果 dev mode 下未设置 `API_AUTH_KEY`，settings 访问只接受 loopback clients。
 
+### 定时研究（Scheduled research）
+
+让研究 prompt 或回测按固定周期重复运行。后台执行器**默认关闭**——启动服务时设置 `VIBE_TRADING_ENABLE_SCHEDULER=1` 才会开启：
+
+```bash
+VIBE_TRADING_ENABLE_SCHEDULER=1 vibe-trading serve --port 8899
+```
+
+然后通过 REST 创建任务。`schedule` 可以是纯整数（间隔**毫秒**）或 5 段 cron 表达式（`分 时 日 月 周`）：
+
+```bash
+# 每 6 小时（cron）
+curl -X POST http://localhost:8899/scheduled-runs \

+# 列出 / 取消

+curl -X DELETE http://localhost:8899/scheduled-runs/<job_id>
+```
+
+每次触发都会在一个全新的 agent session 中运行该 `prompt`（可选回测参数放在 `config` 里），任务持久化到 `~/.vibe-trading/`，重启后依然保留。不设这个开关时，`/scheduled-runs` 端点仍会记录任务，但不会真正触发。配置了 `API_AUTH_KEY` 时，每次请求需加 `-H "Authorization: Bearer <key>"`。
