Conclusion: slab/listing photos are NOT a supported input. Condition assessment requires direct raw-card macro photography — which is what /api/v1/grade/upload asks for. Through-slab results are a lower bound and are not evidence about raw-photo accuracy either way; that study requires ungraded ground truth and is future work."},"forecast_track_record":{"status":"ok","scored_predictions":5612,"rated_ex_push":3607,"pushes":2005,"hit_rate":0.7624,"baseline_rate_all_up":0.8425,"skill_vs_baseline":-0.0801,"weekly_roots_committed_onchain":11,"interpretation":"Judge `skill_vs_baseline`, not `hit_rate`.
