Per-platform breakdown (11 platforms analyzed)

Aliexpress minor high confidence The changes primarily involve UI/UX updates to the authentication interface (passkey registration, sign-in flow) and cookie preference management, with one new policy link added. These are formatting and boilerplate adjustments rather than substantive changes to transparency data or policy content.

Bing minor high confidence Navigation link replacement on DSA researcher program support page: two 'Marketplace Rewards' links removed and replaced with a single 'Software companies' link. This is a minor navigation/boilerplate change unlikely to affect researcher access to DSA transparency data or datasets.

Bing DE minor high confidence Link replacement on DSA transparency page: two instances of 'Marketplace Rewards' links removed and replaced with a single 'Softwareentwicklungsunternehmen' (Software Development Companies) link. This appears to be a navigation menu update rather than a substantive change to DSA transparency data or researcher program content.

Google DE noise high confidence Removal of cookie policy link and associated boilerplate text about cookie usage on transparency.google. This is routine cookie notice management rather than a change to DSA Article 40(4) transparency data or researcher engagement content.

Google DE Youtube Data Catalogue DE noise high confidence No actual text differences detected despite change classification. This appears to be a rendering artifact or dynamic content variation with no substantive modifications to the catalogue page.

Google Youtube Data Catalogue noise high confidence The changes involve converting plain text language options into clickable links with language locale parameters (?hl=xx) and adding cookie notice boilerplate. These are presentation/navigation changes rather than substantive alterations to the API documentation or transparency data itself.

Snapchat noise high confidence Removal of cookie consent banner boilerplate and related policy link from the page. This is a UI/cookie management element change rather than substantive content change affecting the researcher access transparency data.

Snapchat DE noise high confidence The change represents removal of cookie consent boilerplate and UI text from the page, along with the associated cookie policy link. This is a structural/presentation change to the page layout rather than a substantive change to the DSA transparency data or researcher access information.

Wikipedia noise high confidence The diff shows truncated URL fragments in navigation links (Read, View source, View history) and a language link that appear to be rendering or display artifacts rather than actual content changes. No substantive DSA Article 40(4) data catalogue content was modified.

Wikipedia Content Library Mediawiki Content History V1 noise high confidence This change represents a rendering or markup transformation where plain text navigation items have been converted to markdown/HTML links with anchor references. No actual content, datasets, or substantive information has been added or removed from the page.

Wikipedia Editors Information Geoeditors Daily noise high confidence The removed lines are navigation/interface elements (Read, View source, View history links) that are standard wiki page chrome, not substantive content changes. This appears to be a rendering or formatting artifact rather than a meaningful data catalogue update.
