Galactic Rotation from the Compact Fiber II: Structural Regime Split, Realized Coherence, and a Zero-Parameter Benchmark Improvement

This release contains the paper Galactic Rotation from the Compact Fiber II: Structural Regime Split, Realized Coherence, and a Zero-Parameter Benchmark Improvement and its accompanying reproducibility repository. It presents a second-stage compact-fiber galactic rotation model in which the original one-law formulation is extended by a structural regime split in realized galactic organization, together with the code, data pipeline, comparison models, scans, and analysis workflow used to generate the reported results. The repository includes the frozen one-law compact-fiber baseline, the regime-split compact-fiber model, a fixed-baseline MOND comparison model, SPARC-based evaluation across 171 galaxies, threshold and transfer-family robustness scans, failure-cluster diagnostics, radial-acceleration-relation analysis, per-galaxy outputs, and scripts to reproduce the paper’s headline tables, figures, and summary statistics from raw inputs. The paper argues that the compact-fiber framework yields a zero-calibrated-parameter regime-split galactic rotation model that improves on both the frozen one-law baseline and a fixed MOND benchmark on the SPARC sample, while also exposing a specific structural trade-off in a subset of moderate spirals. This Zenodo release is intended as an open scholarly record of both the paper and the full supporting computational workflow.
