High priority: - Fix concurrent race condition for view_count/like_count (atomic update) - Add route request ID tracking to prevent race conditions - Filter get_joke by status=approved (no pending content leak) - Add error feedback for like button Performance: - Optimize random joke query (avoid full table sort) - Limit page_size max to 100 (DoS prevention) Medium: - Add localStorage quota error handling - Handle empty AI response gracefully - Fix generate content title extraction Low: - Add rejected_jokes to stats API - Update dashboard to show rejected count

python crawler/site_crawler.py --id 1 # 采集 site_finder 发现的 #1 站点
|

python crawler/site_crawler.py --id 1,2,3 # 批量采集多个站点
|

python crawler/site_crawler.py --url https://... # 直接采集指定 URL
|
||
python crawler/site_crawler.py --id 1 --no-headless # 显示浏览器窗口
