Expected learning

Tests whether widget_referrer alone reaches YouTube Studio attribution. If Test D appears and Test C doesn't, widget_referrer is the controlling signal. If both fail, both signals may need to be combined (see Test E).

QA checklist

1. Open DevTools → Network.
2. Find the request to youtube.com/embed/UqKvW7ggYWo.
3. Confirm the Referer header is https://d.yt.jaan.md/ — not absent, not no-referrer.
4. Confirm no YouTube Error 153 in the player.
5. Play manually and watch 60–120 seconds.
6. For Test F, confirm DevTools console logs [YT_TEST] … READY and [YT_TEST] … STATE PLAYING. (Not applicable on this page.)
