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.

Vault Boy — The entry claims the only Vault Boy illustration ever cut from a game was an image for Fallout 2 depicting him kicking a pregnant woman, but other cut illustrations exist (e.g., a 'Vault Boy with a noose' for Fallout 2 was also cut).
Yes Man — Yes Man was created by the Big Empty (the Think Tank), not by Robert House.
Craig Boone — The entry says Boone killed his wife Carla to prevent her suffering after she was sold, but in canon he shot her during the sale to prevent her from being enslaved/tortured, not after she was already taken.
Craig Boone — The entry says the quest involves tracking down Jeannie May Crawford and the Legion leader at The Fort, but the quest actually involves tracking down the Legion slaver who bought Carla (not Jeannie May Crawford) and then confronting the Legion leader.
Brotherhood of Steel — The Brotherhood was founded by Captain Roger Maxson in 2077, shortly after the Great War, based at the Mariposa Military Base. — This is incorrect. The Brotherhood was founded at the Lost Hills bunker, not Mariposa.
Brotherhood of Steel — The Vertibird was originally developed and used by the Enclave; the Brotherhood only acquired and used them later, notably in the East Coast chapter under Elder Arthur Maxson after Elder Lyons' death. — This is inaccurate. The Brotherhood of Steel on the East
New California Republic — The NCR was established in 2189 by Aradesh and Tandi, following the destruction of the Master's army by the Vault Dweller in 2162. This is incorrect: The NCR was founded in 2189 by Aradesh, but Tandi was not a co-founder; she was Aradesh's daughter and later b
New California Republic — The Khans were not wiped out and later appear in Fallout 2. This is misleading: The Khans were wiped out as a major faction in Fallout 1 (the Vault Dweller could destroy them), but a small remnant survived and appears in Fallout 2 as the 'New Khans' or 'Khans'
The Great War — The entry states that New York was hit by a nuclear strike, but it is not explicitly confirmed as a target in canon lore.
The Great War — The entry states that fusion cores were a pre-war technology, but in original canon (Fallout 1, 2, New Vegas) power armor used micro-fusion packs, not fusion cores.
The Brotherhood of Steel — The East Coast chapter was originally sent by the West Coast Brotherhood on a mission to acquire technology, with Lyons' interventionist approach developing over time, not from its inception. This is incorrect: Elder Lyons' interventionist approach was present
The Super Mutant Genesis — The entry claims the Enclave sought to weaponize FEV to create obedient soldiers, but canon states their goal was to sterilize or kill mutated life, not create soldiers.
