"methodology_note": "RQ1-only refresh (ECE + reliability diagram) against whatever checkpoint currently sits at best_{model}.pth -- i.e. the promoted dropout-fix checkpoints for xception/vit, deployed 2026-07-25. Same held-out val split (seed=42, val_fraction=0.15) as every other analysis in this project. RQ2/RQ3 unaffected by the dropout-fix and intentionally not re-run here.",
