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.

Irene Adler — The entry states Adler marries Godfrey Norton following her confrontation with Holmes; canonically, she is already married to him by the time of the fire alarm trick (the marriage occurs during Holmes's initial surveillance prior to the climax).
Alison McKay — The STATS section lists 'Canon Status=Canonical' for Alison McKay, but the entry correctly states no character by that name exists; Susan Cushing is the canonical character associated with these events.
Eurus Holmes — Eurus was first introduced in 'The Abominable Bride' special (2016), not Season 4 proper.
Eurus Holmes — Eurus lived with her brothers until they were teenagers (approx. age 12-13), not separated in early childhood.
Sebastian Moran — The entry incorrectly lists Moran's substantive rank as Colonel when Holmes explicitly states in 'The Adventure of the Empty House' that he was a Major in the Bengal Staff Corps.
Sebastian Moran — The entry includes an invented detail claiming Moran considered mimicking a natural heart attack with his air-rifle, which is not found in the canon text where only silence and lack of traceable projectiles are cited as reasons.
Thuggee Order — In 'The Sign of Four,' Tonga uses a poisoned blowpipe dart as the murder weapon in London, not a cloth garrote, despite historical Thuggee associations with strangulation.
Thuggee Order — Jonathan Small is an English ex-soldier who conspired with Indian Thugs (like Tonga) but was not himself a member or initiate of the Thuggee Order.
Foreign Office — Claim that 'The Foreign Office hired Sherlock Holmes only once in the canon' is incorrect; the Foreign Office features prominently in two stories: 'The Adventure of the Second Stain' (client Lord Holdhurst) and 'The Adventure of the Naval Treaty' (client Percy
Foreign Office — Claim that the entity is 'Often referred to simply as 'the Department'' is not supported by canon; in the texts, it is consistently referred to as the 'Foreign Office', unlike Scotland Yard which is commonly called 'The Yard'.
London Underworld — The 'DID YOU KNOW' section contains an incomplete quote regarding Conan Doyle's terminology ('or 'my'), failing to accurately state the full phrase 'my little friends' found in 'A Study in Scarlet'.
Professor Moriarty Antagonist — The entry states his name is 'Professor James Moriarty'; in Arthur Conan Doyle's original canon, he is never given a first name and is referred to only as 'Professor Moriarty'.
Professor Moriarty Antagonist — Holmes compares Moriarty himself (not his criminal empire) to a spider sitting at the center of its web; the entry misattributes the metaphor by stating the empire is compared to the spider.
