Reproducibility data and code for orbital chaos and tidal-history recoverability in Milky Way globular clusters

GC Tidal Memory — Reproducibility Package v1.0.0 This release provides the reproducibility and manuscript-support package for the study: Orbital chaos and potential-dependent recoverability of tidal histories in Milky Way globular clusters Authors: Sobir Turaev and Qudratillo Yuldoshev Affiliation: Ulugh Beg Astronomical Institute, Uzbekistan Academy of Sciences, Tashkent, Uzbekistan Contents The release contains the principal materials required to reproduce and inspect the published analysis, including: manuscript source and bibliography; publication-quality vector figures; machine-readable tables used in the manuscript; frozen sample and phase-space information; functional tidal-memory convergence products; finite-time Lyapunov-chaos classification products; confirmatory endpoint summaries; figure-generation and validation scripts; provenance and SHA-256 integrity records; documentation describing the scientific scope and reproducibility workflow. Scientific scope The analysis distinguishes two quantities that need not behave identically: finite-time orbital predictability, quantified with Lyapunov diagnostics; and numerical recoverability of integrated tidal-history functionals. For the frozen 12-cluster confirmatory sample, all tested cluster–potential groups satisfy the prespecified robust-material-chaos criterion. Functional convergence is potential dependent: the Irrgang13III branch reaches full functional stability for all 12 confirmatory clusters, whereas the McMillan17 branch remains unresolved under the same frozen convergence policy. These results apply to the controlled tested set and should not be interpreted as a population-prevalence estimate. Important limitations The package preserves the manuscript's inference boundaries. No Galactic globular-cluster population prevalence is inferred from the confirmatory sample. No combined McMillan17 endpoint is claimed. Orbital chaos is not used to rescue a failed functional-convergence result. The tidal-history functionals are not calibrated cluster-heating or mass-loss laws. The current confirmatory calculations are conditional on the nominal six-dimensional phase-space coordinates; observational covariance has not yet been fully propagated through the complete functional and Lyapunov analysis. The physical versus numerical origin of the McMillan17 functional non-convergence remains an open diagnostic question. Reproducibility Machine-readable outputs are accompanied by provenance information and SHA-256 checksums. Frozen analysis products are retained without reinterpretation or silent replacement.
