pub fn int8_score(q: &ActRow, key_scale: u16, key: &[i8]) -> f32Expand description
A score as the array computes it against a cached int8 key row (its f16 scale’s bits and its codes): per activation
block of the query, its scale’s m times the integer dot of its codes and the key’s codes, times the key’s scale,
summed exactly and rounded once.
