Out of 8 platforms analysed, only AliExpress showed substantive structural changes (reorganization into a formal DSA Article 40(4) transparency catalogue), while AliExpress Audit showed a localization change without DSA compliance documents, and the remaining 6 platforms exhibited only noise (tracking parameters, UI elements, and cookie banners).

Per-platform breakdown (6 platforms analyzed)

Aliexpress noise high confidence No real change to the catalogue. The real DSA/footer/help content is byte-identical to the last clean capture (2026-06-10); this run's hash differs only because of an intermittent login/carousel overlay — the same rendering issue documented in targets.json for this platform (page alternates between full render and a login/carousel variant without the DSA section).

Bing noise high confidence Only a Trace ID changed (session/tracking token), with no meaningful content, links, or DSA document alterations. This is invisible metadata noise typical of web session tracking.

Booking noise high confidence The change consists entirely of URL parameter updates (tracking labels and session IDs) across 68 links on the page. The label parameters changed from 'gog235jc-10CBQoggJCA2RzYUgHWANoO4gBAZgBM7gBB8gBDNgBA-gBAfgBAYgCAagCAbgCo9LJ0QbAAgHSAiQ1Nzc1ZWNjNC1hN2Y3LTRjYzUtODRhNy05MTRmY2UzOTU2ZGLYAgHgAgE' to 'gog235jc-10CBQoggJCA2RzYUgHWANoO4gBAZgBM7gBB8gBDNgBA-gBAfgBAYgCAagCAbgCs67O0QbAAgHSAiQ2NWVhN2I3Ni1jMDBmLTQxYzctYTVlZC0xNDU4MjQ2NGQyODfYAgHgAgE' and session IDs similarly rotated. No new DSA compliance documents were added, removed, or linked. All URLs link to standard Booking.com properties (admin, careers, business, partnerships, help, etc.) and affiliate services, not to DSA Art. 34/35 systemic risk assessments, Art. 37 audit reports, or Art. 37(4) implementation reports.

Snapchat noise high confidence A cookie consent banner with standard legal boilerplate was added to the page. This is website infrastructure (cookies, consent UI, policy links) unrelated to DSA Article 40(4) researcher access transparency data, making it noise for research archival purposes.

Snapchat DE noise high confidence No real change. The page alternates between two versions of itself (for example, with and without a login prompt), and this capture matched a version seen in a recent check. The original classification from before this correction is preserved in this record.

Wikipedia noise high confidence The changes consist of wiki markup for print/export and navigation sidebar elements (Create a book, Download as PDF, Printable version, In other projects) that are standard MediaWiki template or interface elements, not substantive DSA Article 40(4) compliance data or catalogue content. These are functional page UI components with no research or compliance documentation value.
