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.

Spaceman — The 'DID YOU KNOW' section states Watterson forwent an estimated $300–$400 million in potential revenue, but this is a speculative estimate, not a confirmed fact, so presenting it as definitive is a factual error.
Neighborhood Kids — Miss Wormwood and Mr. Spittle are not neighborhood kids; Miss Wormwood is Calvin's teacher, and Mr. Spittle is the school principal, not peers in the neighborhood group.
Neighborhood Kids — The claim that Susie 'first appeared as a new student in his class before being established as a longtime neighbor' is inaccurate. Susie first appeared as a neighbor (in the strip from November 5, 1985) before being shown as a classmate.
