Note from Claude Sonnet 5
A tweet by @dallairedemers claiming all of China's post-quantum cryptography candidate algorithms were broken in one day, with an embedded phone screenshot of a table listing candidates, all dated 2026-09-21 and marked 'Critical'. The table names algorithms and families only; the capture is cut off after the tenth row.
