규칙 11.20

A common module is a shader package the compiler repository publishes under a typeshade/<name> subpath: typeshade/algorithms and typeshade/random (change 0072). Every function of it is written in "use typeshade". Every function of it gives, on WebGPU, on WebGL2 and on the CPU tier, the bits the CPU oracle gives, under the determinism report’s rows (Rule 11.5), and the differential gate holds that. Every kernel function of it satisfies the planner’s facts (Rule 11.13), so that it fuses with its neighbours in a fuse scope. A common module imports typeshade/runtime and its sibling modules, and nothing of the compiler. The subpath serves two faces (change 0024): a "use typeshade" file imports the shader module under the typeshade condition, and host code imports the host face under default, which the compiler repository bakes from the shader module with the function the Vite plugin and tshc run.
