The database learns to feed itself: automated verification harness (highball verify — tests your installed games under every renderer, detects crashes and black screens, records provenance-complete verdicts; anti-cheat titles skipped by design), 12,491 machine-derived Mac predictions on the database site, Mac-aware anti-cheat map for 1,166 titles, UI polish (game-card hover, humanized engine names, empty states), and a landing page at gauthierpiarrette.github.io/highball.
