Per-platform breakdown (7 platforms analyzed)

Temu noise high confidence The diff shows only obfuscated token strings (mmMwWLliI0O&1 repeated) being added with no semantic content. Given the platform's documented history of alternating between render variants with 4 reversions in 10 changes, this represents a rendering artifact or session-token variant rather than substantive content change.

Tiktok noise high confidence No visible change. The page's technical fingerprint changed, but no text or links differ - invisible page machinery, not content. Classified automatically without AI analysis.

Linkedin noise high confidence Only the 'Last updated' timestamp changed from '8 months ago' to '9 months ago', reflecting the passage of time rather than any substantive modification to the page content. This is metadata drift with no research significance.

Google Google Shopping Data Catalogue substantive high confidence 11 lines of substantive new content added describing AI-edited/created asset labeling requirements under EU, India, and New York regulations, along with 3 new policy reference links. This is meaningful regulatory guidance added to the catalogue page, not a reversion to prior state noise pattern.

Google Youtube Data Catalogue noise high confidence No visible change. The page's technical fingerprint changed, but no text or links differ - invisible page machinery, not content. Classified automatically without AI analysis.

Google DE Google Shopping Data Catalogue DE substantive high confidence Substantive new content added regarding AI-edited or AI-created asset labeling requirements under EU, Indian, and New York regulations, including 3 policy-related links and explanatory notes. This represents meaningful policy guidance addition (11 lines) relevant to DSA compliance transparency.

Google DE Youtube Data Catalogue DE noise high confidence No visible change. The page's technical fingerprint changed, but no text or links differ - invisible page machinery, not content. Classified automatically without AI analysis.
