Each fix ships a test that would have caught the bug:
- ruview_metrics OKS: derive scale from GT extent (no s=1.0 fake-Gold), reject
s<=0, bound the loop to array extents (no panic on short/adversarial input).
- config.validate(): UPPER bounds on window_frames/subcarriers/backbone_channels/
heatmap_size/keypoints/body_parts/batch_size + reject negative gpu_device_id
(closes the config-OOM class); defaults+presets still validate.
- subcarrier.rs: graceful fallback instead of panic on non-contiguous input.
- ablation.rs latency_percentiles: total_cmp + NaN guard (no partial_cmp unwrap).
- tensor.rs softmax(axis): normalize per-lane along the given axis (was whole-
tensor), out-of-range axis -> NnError; fixes densepose per-pixel probs.
- translator.rs apply_attention: real scaled-dot-product attention (was a
uniform 1/seq_len stub that made any "with attention" ablation == without);
mis-shaped checkpoint projections rejected.
