The paper validated it by: ECE (15 bins), Brier, AUROC of 1-confidence, Selective-Risk@90 on POPE-adv and HallusionBench versus base, HA-DPO, RLHF-V and vanilla GRPO; ECE on POPE-adv 0.272 (GRPO) to 0.085, with hallucination metrics (POPE F1, AMBER CHAIR, MMHal) also best and MME/MMBench/MMStar/SEED unchanged; ablation removing the calibration reward returns ECE to 0.268 with accuracy nearly flat..

Efficacy claims — what this technique actually moves, under which conditions, and whether that has been contested.
No efficacy claim filed yet. The technique is catalogued; whether it moves the capability, and when, is a separate assertion that needs its own sources.
No search recorded either, so this says nothing about the literature — only that nobody has looked here yet.

Whether a technique works is a claim. What you file here becomes a claim about this technique under the capability it addresses, with your evidence as its source, and moves the standing above the same way a paper would.
