Agent involvement is not stated, so agent fields and failure classes are omitted. The date of occurrence is not stated and is not estimated. Date disclosed is not stated; the article dates of 2026-07-27 are not treated as disclosure dates. The roughly 600 figure is a press-reported approximation and records_exposed is left out. Root cause is contested: one source says the share feature worked as designed and another refers to configuration failures; root_cause is left out.
