In the front end

A "use typeshade" file never reaches this check with the same mistake: the front end refuses it first, under its own code. This program, compiled at build time, gets:

"use typeshade"

@fragment
export function main(@location(0) uv: vec2): vec4 {
  const m = mat3(1., 0., 0., 0., 1., 0., 0., 0., 1.)
  return vec4(m * uv, 1.)
}

How to fix it

The registry's hint: a matN can only multiply a vecN of the same N

TS8003 TYPE_MISMATCH

Two types that do not fit where they meet (an operator, a condition, a declaration, a return or an argument), or a constant the compiler folds that WGSL refuses: a shift amount past 31, a divisor of 0, clamp bounds that cross or an f32 past its range.
