Per-platform breakdown (6 platforms analyzed)

Aliexpress minor high confidence The change modifies UI label text and button copy on the registration/sign-in interface (e.g., 'Register/Sign in' → 'Register by passkey', 'Continue' → 'Register'). This is a minor wording and layout adjustment with no impact on DSA transparency disclosures, dataset access, or policy content.

Google Google Shopping Data Catalogue minor high confidence The change replaces 'the **Settings** icon at the bottom of the video playe' with 'the Settings icon found in the video player, then sele'. This is a minor rewording and formatting adjustment (removal of bold markdown, slight clarification of location) with no substantive impact on research or transparency documentation.

Google Youtube Data Catalogue noise high confidence No actual content changes detected (0 lines added/removed, 0 links modified). The auto-detected classification of 'noise' is confirmed by the absence of any measurable text or link differences, likely reflecting a URL parameter variant or cache refresh with no substantive impact on the transparency data.

Google DE Youtube Data Catalogue DE noise high confidence No line-level text differences detected and zero links added or removed. The hash change with identical content indicators suggests a non-substantive modification, likely a URL parameter variant (such as ?hl=de language parameter) or invisible metadata update that does not affect research-relevant transparency data.

Pinterest minor high confidence Changes consist primarily of whitespace normalization (double spaces to single spaces), markdown link formatting (email address converted to mailto link), and list formatting (bullet points added for consistency). No substantive content, links, or research-relevant information was altered.

Pinterest DE noise high confidence No line-level text differences detected, zero links added or removed, and zero lines added or removed. The hash change appears to be caused by invisible metadata, session parameters, or encoding variations rather than substantive content modification.
