Omniverse Pantheon+ Late-Time Cosmology Reproducibility Pack

This record provides a self-contained reproducibility pack for the Pantheon+SH0ES late-time cosmology fits used in the Omniverse / Hyper-Omniverse numerical analysis and discussed in the companion monograph.

The archive is designed as an offline referee/reproducibility bundle. It includes the exact solver and helper scripts used in the packaged analysis, cached Pantheon+SH0ES input data, runnable fit scripts for regenerating the reported LaTeX tables, output logs, environment capture files, integrity manifests and SHA256 checksum files, and pre-rendered validation and diagnostic figures. The package is structured so that the core reproduction steps can be run from inside the archive directory without network access.

In particular, this pack preserves the packaged v7.4.x late-time workflow used to generate the Pantheon+ table outputs, along with supporting artifacts such as parameter-forest plots, validation overlays/residuals, Hubble-data figures, and an exact geometric-momentum density figure. It also includes provenance and correction notes documenting the 2026-02-21 tau-prior weighting correction and the harmonization of the packaged MONO bootstrap configuration.

This record should be understood as the main public reproducibility object for the Pantheon+ / late-time numerical component of the project. It supports the companion monograph and related Omniverse cosmology discussion by preserving the packaged data, scripts, logs, and output tables in a stable archival form.

Companion records:

Notes:

This archive is intended as a reproducibility and inspection bundle, not as a general-purpose software release.

The smaller audit-snapshot record documents a specific retained run used for publication-facing H0 discussion; the present record is the broader late-time reproducibility package.
