Native leave-one-training-block-out fits are diagnostics, not a rule for removing blocks. Reference-extrinsic residuals use the full fit clock/scale nuisance values for both transforms, not independent ground truth. Native covered_motions excludes intervals whose offset bounds exceed the reference; counts are retained. Block labels and train/holdout split are unchanged. No SOTA gate or verdict changed.",
