`tools/glsl/build-glsl.sh <outdir>` (Linux, repository root) builds the library GLSL from the HLSL with dxc, SPIRV-Cross and SPIRV-Tools and writes `core.glsl`, `cycles.glsl` and `phacelle.glsl` bodies into `<outdir>`. It does not yet own the committed GLSL; `GlslLowering` still does. `GLSL_DIR=<outdir> tools/device/run-lavapipe.sh` runs that output on lavapipe and compares it with the HLSL results bit for bit instead of judging the committed files.

That comparison is in strict form (dxc `-Gis` and a `NoContraction` decoration on every float result of both modules), and a consumer overrides `CULTMATH_MAX_SITES` in the built GLSL the same way as in HLSL: define it before including `core.glsl`.
`compile-hlsl.ps1` compiles both `CultMath.hlsl` copies as a `lib_6_3` library with the x64 DXC; a warning fails it too (`-WX`).
