Module op 

Canonical op names. Free-form &'static str is accepted everywhere, but sticking to these keeps the report groupable.

Constants

ENGINE_PREFILL_BATCH

An engine-level capability rather than a per-tensor kernel: does this engine have a batched prefill path at all?

FFN_SWIGLU

Whole gate/up/down SwiGLU fused into one dispatch.

GEMM_PREFILL

A real batched GEMM over batch activations (prefill).

MATVEC

One activation against a whole weight matrix (decode).

MATVEC_MULTI

Several independent matvecs sharing one activation (fused q/k/v).
