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.
