We publish our audit record because accuracy claims should be checkable. Every entry on this site runs through an automated fact-audit pipeline (accuracy audit → source-grounded repair → visual QA); this page is generated from that pipeline's own report, not written by hand.
Last full accuracy audit: 2026-08-29 · 10 entries checked · 1 flagged · 1 issues confirmed · 1 corrected · 0 still open
