A Probabilistic Gaia DR3 Catalogue of Stars with Very Low Galactic Rest-Frame Speeds

Review-stage v1.0.5 release of a probabilistic Gaia DR3 catalogue of stars with very low Galactic rest-frame speeds. This version responds to the external deep-review and data-bundle review. The manuscript builds cleanly and the release validation gate passes. Primary counts are Tier A 289, Tier A plus B 541, and Tier A plus B plus C 1,952. The release includes the 20,829-source propagated candidate pool, Tier A, B, and C catalogue products, FITS, CSV, and MRT tables, orbit diagnostics, online Gaia Archive source ID verification, scripts, figures, manuscript source, and documentation. Tier A plus B is the primary catalogue, with 541 stars having probability greater than 0.84 of VGRF below 25 km s-1. The broader orbit-summary catalogue contains 1,952 stars. New in v1.0.5-review: expanded reviewer-response diagnostics, matched-control and entropy-balanced inference, smooth-DF null tests, distance-covariance stress testing, external APOGEE and GALAH radial-velocity audit, GeDR3mock probability-score diagnostics, comparison-potential checks, bundled AGAMA potential ini files, pinned requirements, SHA-256 release checksums, and updated manuscript framing. These v1.0.5 products use the adopted 229 km s-1 Galactocentric convention and the regenerated v1.0.5 catalogue counts.
