Constant RULES 

pub const RULES: [&str; 27];

The steps of a lane a plan can hold back (plan’s held), in the order the lane takes them: the shared rules its kernels link, by their names in the shared table (crate::tensor_graph::fuse); rows_a_warp, the schedule’s four rows a warp for a wide product; the decode step’s products of one activation as one GEMV in parts (gemv_parts, the lane’s own rule in the table); and sequences, a batch’s launches over its sequences as one. The arg-max’s advance closes the step and is always taken; the activation quantizer’s fusion is the fuse_quant knob.
