81 Simulations, Zero Secrets: The Open Validation Manifest

Our design's evidence isn't summarized on our website. It is downloadable from it.

Every design-defining number in MetroVolt traces to a keyed entry in an 81-analysis manifest (S01–S81), deposited in the open under a permanent DOI — inputs, code, outputs, and the acceptance criteria we set before running.

The science

The structure is deliberately two-tier and honest: 48 Tier-1 analyses computed by the deposited reduced-order engines with measured values and pass/fail verdicts; 24 Tier-2 runnable input decks for the community's flagship codes (CGYRO, OpenMC, ASCOT5, DREAM, TGLF) carrying frozen parameters and pre-registered acceptance criteria; 4 named decision gates; and 5 clearly quarantined design-space studies. 76 validation analyses plus 5 explorations: 81 in all, one manifest mapping every S-number to its files.

The bound validation-package PDF is the human-readable companion; MANIFEST.md is the machine-readable spine; CC BY 4.0 is the license. Nothing about the design lives only in prose.

Why it matters

Fusion claims usually ask for trust; this one asks for a code review. Referees, rivals, and customers all download the same evidence — which converts scrutiny from a threat into free verification. In a field of press releases, an auditable manifest is the differentiation.

Straight answersTier-2 decks are confirmations pending HPC execution — deposited so the community can run them before we do. The manifest's honesty is structural: adverse findings hold register rows too.
Every figure in this paper traces to the openly deposited 81-simulation programme (S01–S81) behind the Kronos MetroVolt four-paper design series — data and code at DOI 10.5281/zenodo.21248916 (CC BY 4.0). Read the series, run the code, check us.
Kronos MetroVolt is a conceptual design study. Quantitative values are simulation-derived and carry the feasibility gates stated in the series; Tier-2 flagship-code confirmations are deposited as runnable decks pending HPC execution.
