Kullanıcı panelindeki kayıtların kendi yayınıyla alakasız olduğunu bildirdi. Sebep: channel /live sayfası onlarca alakasız videoId içeriyor (kanal video listesi, öneriler); düz regex sayfadaki İLK videoId'yi alıyordu, bu da rastgele başka bir videoydu — isLive:true kontrolü de aynı bağlamda değildi. yt-dlp'nin extractor'ı kanalın asıl o anki canlı videosunu doğru çözüyor; -f (format) verilmediği için PO-token duvarını da tetiklemiyor (format çözümleme sadece gerçek capture adımında, -f ile, gerekiyor).
