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.

Oliver Putnam — The entry claims that Teddy Dimas is an 'old family friend with ties to the local Greek mafia' who funds the podcast, but in canon his ties to a 'Greek mafia' are not explicitly stated and the term is an oversimplification or invention.
Oliver Putnam — The entry states that in season 4, a fictionalized version of Oliver is portrayed by Zach Galifianakis, but in canon Galifianakis plays a fictionalized version of himself as the actor portraying Oliver, not a direct fictionalized version of Oliver.
Tim Kono — The entry incorrectly states that the group of four friends (Tim, Mabel, Oscar, and Zoe) was formally called 'The Hardy Boys'; in canon, 'The Hardy Boys' was a nickname Mabel used only for herself and Tim.
Jan Bellows — Jan Bellows did not poison Tim Kono; she poisoned herself and framed Tim Kono's death as part of a pattern, but the actual killer of Tim Kono was Jan Bellows, who stabbed him with a knife (not poison).
Jan Bellows — The tagline and lore state she was revealed to be the one who poisoned Tim Kono; this is incorrect as the murder weapon was a knife, not poison.
Theodore — Theodore first appears in Season 1, Episode 2, not Episode 1.
Theodore — Theodore is not named after Uma's late husband; that detail is never mentioned in the show.
John Hoffman — The cast of the fourth season won the Screen Actors Guild Award for Outstanding Performance by an Ensemble in a Comedy Series
Martin Short — The entry states that a young version of Oliver is portrayed by Hayes McCracken in season 5, but season 5 has not aired, so this claim is speculative and not established canon.
Ben Platt — The entry is about Bethany Platt from Coronation Street, not Ben Platt from Only Murders in the Building, which is a factual misattribution.
Ben Platt — The entry states Katie Redford was cast as the new Bethany in 2015, but Lucy Fallon was actually cast in that role, which is a factual error about the character's casting.
Taissa Farmiga — Taissa Farmiga does not portray Mabel Mora; Selena Gomez portrays Mabel Mora in 'Only Murders in the Building'.
Taissa Farmiga — Mabel is not a 'recurring character'; she is a main character in the series.
