Back to the Future Codexery — Data & Quality

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.

Recent findings (audit lane, verbatim)

Lorraine McFly — Lorraine's mother is not named 'Stella' in the established film canon; she is referred to only as Mrs. Baines or remains unnamed.

Lorraine McFly — Biff Tannen was never Lorraine's high school boyfriend; he was a classmate and bully of George McFly, with no romantic relationship established between him and Lorraine.

Seamus McFly — Seamus McFly is Marty's great-grandfather, not his great-great-grandfather.

Seamus McFly — Seamus was already an established Hill Valley resident with an adult son by 1885, so claiming he arrived 'around 1885' contradicts the canonical timeline.

Marvin Berry and the Starlighters — Claiming Marty McFly 'saved the event from silence' contradicts canon; the Starlighters were already on stage actively performing 'Earth Angel' (albeit poorly) before he took over.

Marvin Berry and the Starlighters — Listing Marty McFly as a 'Key Member' is factually incorrect; canon establishes him only as a one-time guest substitute for a single performance, never an official band member.

Twin Pines Mall Management — In the altered 1985 timeline, the mall is canonically renamed 'Single Pines Mall' after one pine tree is destroyed; attributing 'Operational' status to 'Twin Pines Mall Management' in 1985 without distinguishing between the original and altered timelines confl

Enchantment Under the Sea Committee — The entry incorrectly lists 'Doris' as a McFly sibling; official canon only includes Dave, Linda, and Marlene.

Biff Tannen's Car Wash Gang — The encyclopedia incorrectly claims Match, Skinhead, and 3-D are explicitly shown working at the car wash in Restored 1985; only Biff Tannen is visible washing a car in the final scene of Back to the Future Part I.

Western Town Residents (1885) — Doc Brown did not use the alias 'Clint Eastwood'; Marty McFly used this alias upon arriving in 1885.

Western Town Residents (1885) — No commemorative plaque on the schoolhouse is shown or focused on within the film's depiction of the 1985A timeline.

George and Lorraine First Meeting — The entry incorrectly claims George helped push-start Lorraine's car; canon shows Biff Tannen pushed George into her path, causing her to brake and check on him.

George and Lorraine First Meeting — The entry incorrectly states Lorraine called George 'Calvin Klein' and that the line was improvised by Michael J. Fox; canon shows she used the name for Marty's disguise, and it was scripted by Robert Zemeckis and Bob Gale.
