The two open deposits.
Kronos publishes its code and data, not just its claims. Two citable archives hold the physics behind both machines — read them, run them, check us.

The Kronos claims are meant to be checkable. Rather than describe the physics and ask you to trust the summary, the company deposits the evaluators, the input data, and reproduction runbooks in two archives with permanent DOIs.
- The breeder
- The spherical-tokamak D–T breeder (HYPERION): a pure-NumPy evaluator that reproduces the frozen design point — Q 3.424, 88.7 MW, 9.86 MA, ~4 kg/yr tritium — from one command. DOI 10.5281/zenodo.21746157
- The burner
- The D–³He tandem-mirror generator: the mirror engine, the closure suite, and the frozen fuel-cleanliness trajectory. Physics only — economics are deliberately out of scope. DOI 10.5281/zenodo.21746479
Both engines report their own gaps: the breeder's damage-life-limited availability and its triangularity-sign caveat; the burner's plug-density requirement and corrected bremsstrahlung. Named, not hidden. Both papers are submitted to IOP with peer review in progress; arXiv preprints link on posting.
You do not need to download anything to see them run: the live simulation executes the breeder engine in your browser and reads the burner's precomputed closure map — the exact deposited code.
