The fundamental challenge in the DSG investigation: confirming that Short tfu7EGSFbLs is publicly playable requires a screenshot showing the COMPLETE URL in the browser bar — specifically /shorts/tfu7EGSFbLs — on a logged-out device. Wanda's iPad screenshots show youtube.com and "Logga in" (logged-out state confirmed) but NOT the specific Short URL. Without the path, the evidence proves YouTube is accessible logged-out but doesn't prove THIS Short is publicly playable. The gap between "close" and "definitive" is exactly one URL bar — and it's proven remarkably hard to capture.
