We specify a pre-registered protocol for Following the July 2023 LK-99 room-temperature superconductivity preprint, how many distinct independent reproduction attempts (defined by independent research groups) reported results within the first 30 days, and what was the distribution of their findings? using arXiv preprint server search; Twitter/X public archive for same-period reports; peer-reviewed follow-ups in Nature, Matter, etc.

We introduce active geometry: topologically non-trivial crystalline defects are not passive perturbations but geometric constraint operators that actively structure quantum phases. The falsifiable prediction Gamma_21(50 nm) > 5 micro-eV distinguishes classical exponential decay from algebraic decay.
