Per-platform breakdown (9 platforms analyzed)

Bing noise high confidence All changes are trailing slash additions to existing support URLs (e.g., microsoft-365 → microsoft-365/) and one URL path normalization (all-products → all-products-list, pc-accessories → surface/accessories/pc/). These are URL structural variants that resolve to the same or functionally equivalent support pages; no new resources or access points were added or removed.

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.

Aliexpress noise high confidence No change to the catalogue. Everything that changed on this page was outside the researcher-data section - menus, banners, or promotional elements. The catalogue text itself is identical. The original classification from before this correction is preserved in this record.

Xvideos 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.

Pinterest 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.

Google minor high confidence A social media follow call-to-action for YouTube was added to the page footer or navigation area. This is a minor formatting/UI addition with no impact on substantive transparency data, researcher engagement resources, or DSA Article 40(4) catalogue content.

Google Google Search Data Catalogue noise high confidence The diff shows 66 lines added and removed, but the content consists primarily of page metadata, UI framework elements, and form structure (Help Center navigation, feedback form fields, IDs, boolean flags) rather than substantive DSA Article 40(4) transparency information. This appears to be a page template or rendering refresh with no change to actual dataset descriptions or access conditions.

Google Google Shopping Data Catalogue 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.

Google Youtube Data Catalogue 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.
