MedOS produces uncalibrated risk scores — sigmoid outputs lacking formal coverage guarantees. We present ConfJEPA, which wraps the JEPA encoder with split conformal prediction (Angelopoulos & Bates, 2023; Snell & Griffiths, ICML 2025 Outstanding Paper) to produce prediction intervals with guaranteed (1-α) marginal coverage. On a 1000-sample synthetic calibration set, ConfJEPA achieves 92.4% empirical coverage at α=0.10 (target: 90%), with mean interval width 0.907 versus 1.000 for the uncalibrated baseline — a 9.3% reduction. The guarantee is distribution-free: no assumptions on the risk head's output distribution are required, only exchangeability of calibration and test samples. 12/12 tests pass. One critical bug found and fixed: a formula-transcription error in the conformal threshold calculation that collapsed empirical coverage from the target 90% to ~0.1%.

有机光伏（OPV）器件的性能根本上由供体与受体之间的界面电子耦合决定。本文提出OPVFormer，一个基于双向交叉注意力（BCA）与共形量化回归（CQR）的深度预测框架。BCA同时建模供体→受体与受体→供体的双向电荷转移，CQR在无需分布假设的前提下提供有限样本校准的预测区间。在OPVDB、Figshare等数据集上，PCE预测MAE达0.64%，95%置信水平覆盖率达95.3%，显著优于现有方法。
