What Reproducibility Does and Doesn't Prove
Reproducing a computation proves it follows from the model and inputs — not that the unbuilt machine will behave that way.
An honest account of the limits of reproducibility: re-running a Kronos deposit proves the published number follows rigorously from the stated model and inputs. It does not, by itself, prove that a machine — not yet operating, though the HYPERION breeder is scheduled to begin construction in Q2 2027 — will match the model. Kronos states both halves of that clearly.
This is why every figure is labelled a computed design target, and why the binding gates are named separately.
Common questions
That a published number follows correctly from the stated model and inputs — that Kronos did the calculation it says it did. Anyone can re-run the open engines and get the same result.
That an unbuilt machine will behave exactly as modelled. That is why every figure is a computed design target, and why physical gates and high-fidelity analysis remain on the path to build.
