35d91faDelete the TypeScript solver; the .m models are the only implementationJeremy Magland 2 * The whole suite on desktop WebGPU (Google Dawn), against the real pipeline:
3 * MATLAB source -> numbl lowering -> generated WGSL -> GPU.
35d91faDelete the TypeScript solver; the .m models are the only implementationJeremy Magland 5 * The same three check modules run in the browser (test.html), so both GPU
6 * stacks get the same guarantees. Run through vite-node, which is what resolves
7 * numbl's compiler sources and the `?raw` model imports:

27 * and move on — CI uses it, because the browser suite runs the very same check
28 * modules on SwiftShader. A plain local run still fails loudly, so a missing GPU
29 * is never mistaken for a pass.
