dxc runs with -WX; a ShaderPath that is not a file throws naming the parameter and entry index, never the path; the GLSL wrapper builds a struct parameter from its declaration's field zeros. design.md and README state the struct-argument twin rule, the span twins and the missing shader identity. No C# change; the compiles run on Starfire after the last commit. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
