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.

Sheldon Cooper — Sheldon's first word was 'hypotenuse' at age four, not three.
Sheldon Cooper — Sheldon earned his first degree at age 14, but it is not specified as summa cum laude in canon.
Leonard Hofstadter — The engagement occurs in the season 7 finale 'The Status Quo Combustion', not 'The Locomotive Manipulation'.
Leonard Hofstadter — The wedding in Las Vegas takes place in the season 9 episode 'The Celebration Experimentation', not 'The Opening Night Excitation'.
Howard Wolowitz — The entry states Howard's degree is from MIT, but the show indicates he attended MIT only for his master's degree, not his bachelor's; his undergraduate degree is from an unspecified institution.
Howard Wolowitz — The 'DID YOU KNOW' section claims Howard can speak nine languages, but the list includes nine languages plus Sindarin and Binary ASCII, making the count inconsistent; the show explicitly states he knows French, Mandarin, Russian, Arabic, Latin, Persian, Japane
Penny — Penny and Leonard begin dating at the end of season 2 is incorrect; they begin dating at the end of season 1.
Penny — They break up in season 3 is incorrect; they break up at the start of season 3, not during it.
Amy Farrah Fowler — Amy makes her debut in the third season finale titled 'The Lunar Excitation.' She actually first appears in the fourth season premiere, 'The Robotic Manipulation.'
Amy Farrah Fowler — The site matches her with Sheldon Cooper because the two share many similar traits. Actually, the dating site matches her with Sheldon because Howard and Raj created the profile using Sheldon's information.
Penny Moves Into Apartment 4A — The entry states the event is 'Penny Moves Into Apartment 4B', but in the show, Penny moves into Apartment 4A. Leonard and Sheldon live in 4A, and Penny moves across the hall into 4B.
Sheldon Meets Amy Farrah Fowler — The first meeting between Sheldon and Amy occurs at a coffee shop, not at Amy's apartment.
Sheldon Meets Amy Farrah Fowler — Penny does not personally find Amy or vet her profile; Sheldon browses profiles and contacts Amy himself.
The Comic Shop — The entry overstates the comic book store's role as a recurring physical set and vital social hub; the store is rarely seen on screen and not a consistently depicted location like the apartment or university.
The Comic Shop — The entry incorrectly claims Sheldon rarely enters the store unless dragged; in canon, he is a frequent and willing visitor with a pull list.
