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 {
  return vec4(uv, uv.x > 0.5 ? uv : 1., 1.)
}

How to fix it

The registry's hint: both branches of a select/ifExpr must share a type
