Constant LINEAR_TANH_FP32 

pub const LINEAR_TANH_FP32: TosaFp32OperatorCase;

Three-operator FP32 graph: tanh(x · w + bias) with constant zero points and a [1, 1, 2] bias broadcast over the [1, 2, 2] product. Inputs are the mock classifier’s features and weights; the oracle is evaluated in binary64 and rounded.
