pub fn head(
weights: &HyperConnectionHeadWeights,
x: &[Vec<f32>; 4],
rms_norm_eps: f32,
hc_eps: f32,
) -> Vec<f32>Expand description
build_hc_head: the final collapse of hc streams into one output
vector before unembedding – structurally the pre-gate half of
pre, with no post/comb since nothing follows it.
