The Expanse Codexery — Data & Quality

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.

Recent findings (audit lane, verbatim)

Camina Drummer — First Appearance:=Babylon's Ashes (Book) - Incorrect. Camina Drummer first appears in Leviathan Wakes (Book 1), where she commands the Nagasaki and rescues Holden and Naomi.

Chiang — Subject Mismatch: There is no major canon character named 'Chiang' matching Bobbie Draper's description; the entry misidentifies the subject.

Chiang — Book Canon Error: In the book series, Bobbie Draper does not investigate the destruction of the Donnager (a Season 2 TV show arc); she is introduced later in *Caliban's War* without this specific investigation plotline.

Alex Kamal — The entry conflates TV show and book canon by stating Alex Kamal's status as 'Deceased' based on Season 6 without noting that he survives until the end of the original book series (Leviathan Falls).

Amos Burton — The agency Amos worked for is never referred to as 'Miller & Sons' in canon; Detective Miller operated either within the Ceres Police Department (CPD) or as a private investigator under his own name.

Amos Burton — Amos did not cross paths with James Holden during the destruction of the Canterbury; they met on Ceres Station after the event, while investigating Julie Mao's disappearance.

Outer Planets Alliance — The conflict is not canonically referred to as 'the Belt War'; it is generally described as ongoing tensions or specific crises (e.g., Free Navy Crisis) without a formal singular war declaration of that name.

Outer Planets Alliance — Claiming Tycho Station served as the new headquarters for Camina Drummer's moderate faction is not supported by canon; while the station survived, Drummer operated primarily with the UN/OPA alliance fleet during the Free Navy conflict rather than basing hersel

Tycho Faction — Originally established as a corporate mining outpost: Tycho Station was built by the United Nations (UN) as a military and administrative station, not originally as a corporate mining outpost.

MCRN — Bobbie Draper served as a Marine in the Martian Congressional Guard (MCG), not as an MCRN Commander.

MCRN — The catastrophic losses against Earth's UN Navy occurred during the First Interplanetary War prior to the Ring Gate era; by the Ring Gate/Laconia conflict, Mars and Earth were allies.

The Ring Gates Network — The entry claims the network consists of exactly fifty-five active gates/worlds; canon establishes the Ring Gate network connects over 1,300 star systems (often cited as approximately 1,382 habitable worlds).

The Ring Gates Network — The entry states Laconia houses a 'central Hub connecting all other gates'; this is incorrect as the Ring Gates form a decentralized mesh network without a single physical central node or hub in any specific system for transit routing.
