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.

Gasai Family — The claim that the third corpse found in the Gasai home is 'the original Yuno Gasai of the Second World' is incorrect; in canon, the third corpse is the body of the original Yuno Gasai from the First World.
Gasai Family — The 'DID YOU KNOW' section states that 'the Yuno Gasai of the main timeline was killed and replaced by an alternate version of herself who had already won the Diary Game in her own timeline.' This is imprecise: the main timeline (First World) Yuno was killed a
Future Diary System — The entry states 'Yukiteru Amano's random future diary' — this is inaccurate. Yukiteru's diary is called the 'Random Diary' (or 'Random Prediction Diary'), but it specifically records events Yukiteru himself observes, not truly random predictions.
Future Diary System — The entry claims 'the idea of multiple cycles with persistent memories is not a confirmed fact of the original canon' — this is incorrect. In the original canon (both manga and anime), it is confirmed that multiple cycles exist and that Yuno Gasai retains memo
Gamer Diary — The entry title and tagline refer to a 'Gamer Diary,' but the correct name of Minene Uryu's diary is the 'Escape Diary.'
Gamer Diary — The 'DID YOU KNOW' section incorrectly states Minene's motive as wanting to destroy all religion after her parent, whereas her canonical motive is to destroy all religion due to the death of her parents.
Akise Aru Intervention — In the main series, Deus does not give Akise the Detective Diary; it is given to him by the Eighth Diary user (Hinata Hino) in both the main series and the Paradox side-story.
Akise Aru Intervention — The claim that the Detective Diary 'cannot predict entries from a diary that originates from a different world line' is not explicitly stated in the canon; Yuno's diary from the Second World is from a different timeline, but the diary's limitation is more accu
World Two Yukki Death — The entry states that Third World Yuno stabs Yukiteru, but in the canon, it is World Two Yuno who kills Yukiteru in World Two.
World Two Yukki Death — The entry claims that Third World Yuno becomes God, but in the canon, it is World Two Yuno who becomes God of World Two after winning the survival game, not Third World Yuno.
Minene Uryu Attack — Minene Uryu does not die in the vault explosion during the main Survival Game; she survives that explosion and later dies in a separate hospital explosion caused by Yuno's bomb.
Minene Uryu Attack — Minene appears alive in the main timeline after the vault explosion, not only in the alternate timeline of Future Diary: Redial.
Second Yuno Appearance — The entry states Yuno's father released her from the cage, but in canon it was her mother.
Second Yuno Appearance — The entry says Yuno did not attempt suicide immediately after killing Yuki in the first timeline, but in canon she did attempt suicide immediately after killing him.
Chiyoda High School — The series did not originate as a short story posted on Sumiko Arai's Twitter account between July and September 2021. Future Diary (Mirai Nikki) was originally a manga by Sakae Esuno, serialized from 2006 to 2010, and has no known connection to a Twitter stor
