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.
This is a fiction/fan codex: entries describe an in-universe canon. Our audits check canon and internal consistency — external fact-checking does not apply the way it does on real-subject codexes.
