+All three task heads combined: approximately 377K learned parameters. The decomposition and normalization add zero. For comparison, the standard Argus multi-task heads (FCOS detection + linear segmentation + DPT depth) total approximately 30M parameters on the same backbone.

 The scale decomposition is derived from the adjoint structure of the upsample/downsample pair. A machine-checked proof of the decomposition's cross-scale orthogonality properties is available at `phanerozoic/threshold-cofiber-detection`.
