Per-platform breakdown (5 platforms analyzed)

Google Youtube Data Catalogue noise high confidence Google rotated its devrel-devsite static asset version hash (vb08cb→v6ae67) across all CDN URLs — CSS, JS bundles, favicon, footer image. Content text is byte-for-byte identical; the feature-flags list in the embedded JS config contains the same flags in a different order. No DSA-relevant content changed.

Google DE Youtube Data Catalogue DE noise high confidence Identical cause to the EN version — same CDN asset hash rotation on the German (?hl=de) variant of the YouTube Data API overview page. Analytics dimension-key order also shuffled (non-deterministic serialisation). No DSA-relevant content changed.

Linkedin minor high confidence Two cosmetic markup changes on the LinkedIn ‘Data access for researchers’ help page: (1) the breadcrumb navigation link lost its inline ‘#’ heading prefix, splitting onto two lines; (2) the page’s main heading ‘Data access for researchers’ was promoted from H2 to H1. No policy language or data-access conditions were modified.

Linkedin DE minor high confidence Exact German-language mirror of the LinkedIn EN change — same H2→H1 heading promotion on ‘Datenzugriff für Forscher:innen’ and the same breadcrumb rendering tweak. Deployed simultaneously with EN, confirming a site-wide CMS template update. No policy content affected.

Snapchat minor high confidence Single line changed (1 added, 1 removed) on the Snap researcher-access page (values.snap.com). The previous snapshot was captured in a minimal schema without extracted text; the new full snapshot shows the page content is intact and unchanged in substance. No DSA transparency policy content was modified.
