Where Missingness Occurs Matters: Locked Result Data and Aggregate Analyses

Privacy-sanitized SQLite archival copies, the formal task manifest, frozen analysis input, exclusions, panel-completeness checks, aggregate statistical tables, SVG figures, and post-confirmatory summaries for a confirmatory study of context-query missingness asymmetry in TabPFN v2 and TabICLv2. The formal analysis contains 10,920 planned tasks, 10,915 completed metric records, and five disclosed failures confined to a descriptive natural-missingness panel. Raw OpenML data and model checkpoints are not redistributed.
