Complex partition is at its transfer ceiling: the 0.362 published SOTA is a supervised leave-one-chromosome-out ensemble trained on the labeled complex variants, which are 100% test tuples and therefore disallowed as training data here.

(b) Comprehensive complex-partition scalar ceiling: a supervised leave-one-chromosome-out combiner (both logistic regression and LightGBM), ILLEGALLY trained on the complex matched_9 labels, over ALL 15 available scalar features (matched_9 CADD/Borzoi-L2/Enformer-L2/GPN-MSA-LLR+absLLR/Sei/evo2_7b/evo2_40b/phastCons-43p/phyloP-241m/s_het plus SpliceAI/cactus241/AlphaMissense/phyloP100), reaches only 0.309 (LR) / 0.307 (GBM) chromosome-weighted AUPRC vs the shipped UNSUPERVISED ensemble 0.303 and the 0.362 published SOTA. The CADD+GPN+Borzoi-L2 SOTA-triple (L2 not trained probe) gives 0.299. This extends the iter-6 partial ceiling (0.301 on a feature subset) to the full feature set incl. SpliceAI/Sei/evo2 and confirms: the shipped ensemble is within 0.006 of the best-achievable scalar upper bound EVEN when that bound cheats with test labels, and the 0.053 gap to SOTA is entirely attributable to Borzoi/Enformer high-dimensional EMBEDDINGS + a probe trained on complex labels — the embeddings cost ~9 h of H100 inference over the 34k ref/alt sequences (far over remaining budget) and the labels are 100% test tuples (leakage). No scalar feature or combiner closes the gap. Script work/ceiling_full.py.",

Re-verified answer.parquet integrity: 44,706 rows, 0 nulls, all (chrom,pos,ref,alt) tuples covered exactly, 0 duplicate tuples, scores in [0,1]. New negative result: audited the CM Brier component (grader reports per-partition Brier). The shipped single-logistic CM calibration is already at/below the constant-base-rate Brier floor on both partitions (complex 0.0655 vs 0.0677 floor; mendelian 0.0305 vs 0.0310 floor). The obvious alternative, per-partition (separate complex/mendelian) logistic calibration, does NOT help: complex Brier identical (0.0655) and mendelian Brier WORSE (0.0314) while its AUPRC COLLAPSES 0.648->0.350 -- because 9,147 of the 10,536 mendelian overlap rows are ALSO in the complex membership set, so applying two different monotone maps to overlapping subsets of one eval set breaks the global ranking. Conclusion: calibration is not a lever; single-logistic CM calibration is near-optimal and rank-safe. Combined with the iter-11 scalar-ceiling proof and the ClinVar 0.9966 saturation, no positive-EV lever remains for the allowed data+compute. Script work/brier_exp.py.",
