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.

343 Guilty Spark — In Halo: Combat Evolved, 343 Guilty Spark addresses the protagonist as 'Spartan', not 'Master Chief', and lacks knowledge of John-117's specific identity at that time.
343 Guilty Spark — In Halo 2, 343 Guilty Spark attempts to activate Installation 08 (the replacement ring on the Ark), not the original Installation 04 which was already destroyed.
Lord Hood — Intro Title Error: Described as 'Commander-in-Chief of the United Nations Space Command'. Correction: The Commander-in-Chief is the President of the UEG; Hood was Fleet Admiral and head of the UNSC Navy/High Command.
Lord Hood — First Major Appearance Error: Lists 'Halo: The Fall of Reach' as a first major appearance. Correction: Hood does not appear as a significant character in the original 2001 novel; his backstory was retroactively expanded, but Halo 2 (2004) remains his first maj
Rtas 'Vadum — Rtas 'Vadum's name follows the standard Sangheili naming convention (Given Name + Clan), not a unique exception.
Rtas 'Vadum — Thel 'Vadam formed an alliance with humanity in Halo 2, preceding Rtas 'Vadum's fleet commitment.
Insurrectionists — The Insurrectionists are not colloquially known as the United Rebel Front; the URF was a specific major faction within the broader movement, while 'rebels' is the common colloquialism for all Insurrectionists.
Insurrectionists — 'Red Team Defectors' is not a canon Insurrectionist group; there is no record of an organized faction by this name in established Halo lore (likely a confusion with Spartan-II designations or fabricated).
UNSC — The UNSC is canonically a military and exploratory agency distinct from the United Earth Government (UEG), which serves as the civilian political authority; describing the UNSC as humanity's 'political engine' conflates these separate entities.
UNSC — The current status description inaccurately implies the Great Schism was sequential to the Human-Covenant War rather than concurrent, and omits critical ongoing conflicts with the Banished and the aftermath of the Created uprising relevant to the 2560 timeline
Forerunners — The entry incorrectly identifies Ghibalb as a moon and the Ur-Didact's homeworld; canon establishes Ghibalb as the planet serving as the Ecumene capital, while Charum Hakkor was the Didact's homeworld.
The Forerunners and the Halo Array — The entry states the Forerunners upheld the Mantle for 'approximately one million years'; canon establishes their reign as the dominant galactic power (the Ecumene) lasted approximately 100,000 years before the Flood War.
The Forerunners and the Halo Array — The Stats section lists the Fate as 'Extinct', which contradicts the Lore and Did You Know sections that explicitly state some Forerunners survived by fleeing to shield worlds or stasis; while the species is largely extinct, acknowledging survivors makes 'Exti
The Covenant Empire — The entry incorrectly attributes Covenant origins solely to finding Halo rings elsewhere, omitting the canonical discovery of Forerunner artifacts on Charum Hakkor.
