The Cryogenic Referent Registry
Ten referent records audited against six criteria: what each can and cannot support in cryogenic tank model validation.
Articles
Two shelves under one roof: technical notes that audit the cryogenic propellant record, and research articles that stand apart from that series — Kerr flybys, and AI admission-kernel work. Every published item carries a Zenodo DOI.
AI research
Admission kernels, Class A / Class B, and why an unconditioned “AI risk” percentage does not identify a single object.

The 10% AI Extinction Number Does Not Measure "AI": It Mixes Two Different Objects
Research monograph v3.8-EN — admission kernel and applied non-identifiability of unconditioned expert AI-risk aggregates
Spaceflight research
Geometry-first mission questions with published plants — not cryogenic tank validation.
Spaceflight research
The usable time-dilation of a Kerr flyby is geodesic
What observer-to-proper-time ratio a returning spacecraft can collect, once the exit is limited to published plasma and nuclear-thermal plants
The Accuracies Travelled Back. The Warning Did Not. K-Site, 1992–2025
A 1992 liquid hydrogen dataset, five downstream validation documents through 2025, and the one piece of experimental context that still does not travel.
286 Pages of Candor, and Still No Assembled u_D
SHIIVER — the best-documented cryogenic tank test I have read — and what a modeler still cannot reconstruct from it.
The MHTB Primary Is a TVS Performance Study, Not a Self-Pressurization Characterization
Auditing the 161-page primary report beneath a liquid-hydrogen validation citation examined in this series.
The Tank Data Matched to 5%. Its Error Bar Did Not Travel.
K-Site self-pressurization at 3.5 W/m², 29 % and 49 % fill: u_D on the compared result cannot be assembled from what travelled
Published
The five notes above and the supporting dataset were published on Zenodo (Notes 000–003 on 12 August 2026; Note 004 on 9 September 2026). Notes 000–003 remain frozen at v1.0, with 30 errata of our own recorded in Note 000. Each carries a permanent identifier: the Zenodo deposit is the citable version of record, and the full text on this site is the same version. Corrections do not overwrite a published note — they produce a new version with its own identifier, and every prior version stays retrievable.

Who wrote this
ElarionX is a one-person project. The notes and research articles are written by an independent researcher working with AI assistance, and no independent human reviewer has yet examined this work — it is exploratory, and labelled as such throughout.
Competing interest, declared (CPMS notes). ElarionX develops cryogenic engineering models, and the referent registry described in the technical notes is a planned product of that work. The full statement is in Note 000, §IX.
The cryogenic notes are a documentary audit of public NASA experiment reports and the documents citing them. They are not conducted for, on behalf of, or in association with NASA, and make no agency compliance or certification claim. Research articles outside that series carry their own scope boxes.
