Log-rotated structure of nuclide space: reproducible computational audit

This record registers a reproducible computational finding concerning the organization of nuclide discovery space. The package documents a log-transformed and 45-degree rotated representation of nuclide coordinates, using x = log Z, y = log N, u = (log Z + log N) / sqrt(2), and v = (log N - log Z) / sqrt(2). The analysis shows that known nuclides and high-scoring candidates selected by the historical_core operator concentrate into a narrow scale-ratio band in the log-rotated space, whereas the full candidate grid does not exhibit the same compression. The package includes source data snapshot, parsed discovery records, verification metrics, structural audit outputs, figures, protocol documents, and replication scripts. The historical_core score is computed from historical information available at each cutoff and does not use future discoveries as score inputs. Future discoveries are used only as holdout labels for evaluation. The package therefore documents a reproducible structural pattern in nuclide space and provides the materials needed to inspect and reproduce the calculation. (Czech language only)
