ExoEarth Research Compendium v1.1: A Conditional Population Estimate of Narrow-Domain Exo-Earth Candidates around Old G Dwarfs in the Milky Way's 7–9 kpc Annulus

Research Compendium v1.1 accompanying the manuscript “A Conditional Population Estimate of Narrow-Domain Exo-Earth Candidates around Old G Dwarfs in the Milky Way’s 7–9 kpc Annulus.” The compendium provides extended methodology, numerical results, validation analyses, sensitivity studies, provenance, and reproducibility documentation supporting the shorter research article. It includes the Kepler DR25 occurrence reconstruction, the JJ/PARSEC/TAMS Galactic host population, Model 1 and Model 3 comparisons, direct target-support diagnostics, prior and candidate-vetting sensitivities, host-age tests, and explicit interpretation boundaries. Version 1.1 incorporates editorial clarifications and additional documentation while retaining the principal numerical results, scientific tables, equations, and figures. The associated software pipeline v4.0.4 is archived separately at DOI 10.5281/zenodo.22168215.
