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.

Google Google Shopping Data Catalogue minor high confidence A single sentence was rephrased for clarity ('For subtitles' → 'To see subtitles') and a text span was converted into a hyperlink to YouTube captions documentation. While a new outgoing link was technically added, this is a minor wording and formatting improvement with no change to the substantive content or research-relevant information about the catalogue.

This is a recurring UI rendering toggle (as documented in platform history), not a substantive content or access change. The net +37 links masks functionally identical self-referential navigation variants.
