Field notes
At capture, the site lists 54 incidents and 93 articles, with a last-updated date of November 11, 2026. Entries use severity labels and mark when only part of a reported population or data set is implicated; the homepage’s featured case, for instance, distinguishes a card-data subset from the larger affected group. The site says its incident records are based on official announcements, so its framing is a guide to disclosures rather than evidence of independent investigation.
