Reproducibility at Kronos
Kronos's answer to 'how do we know?' is not a claim — it is a download. The engines, inputs and expected outputs are public, and they reproduce.
The Kronos design record is deposited openly on Zenodo under CC BY 4.0. Each deposit contains the reduced-order engines, the input decks, and the expected outputs, so an independent reviewer can reproduce the published numbers rather than take them on trust.
Two tiers of reproduction
- Tier 1 — byte-exact. Deterministic calculations reproduce to the exact byte on a matching environment.
- Tier 2 — tolerance. Calculations with legitimate numerical variation reproduce within a stated tolerance.

The Kronos answer to 'how do we know?' is a download: the engines, inputs and expected outputs are open and reproduce, byte-exact for deterministic results and within a stated tolerance otherwise. Reproducing a computation proves the number follows from the model and inputs — not that an unbuilt machine will match it, which is why every figure is a computed design target.
Common questions
Download the relevant Zenodo deposit (breeder 10.5281/zenodo.21746157, burner 10.5281/zenodo.21746479), set up the pinned environment, and re-run the engine against the provided inputs. Deterministic results reproduce byte-for-byte; others within a stated tolerance.
No. It proves the number follows rigorously from the stated model and inputs. It does not prove an unbuilt machine will match the model — which is why every figure is labelled a computed design target.
