Declare cuda-tile[tileiras]==1.6.0 in the prepare extra so uv sync installs tileiras, nvcc, NVVM, and CUDA CRT. Preserve existing locked package versions and document the compiler dependency in the preparation guide. Validation: uv lock --check --offline; locked preparation/test installation dry runs for Linux aarch64 and x86_64; isolated ARM64 Linux installation on spark2 with cuTile compiler discovery and tileiras/ptxas version checks. Model preparation and GPU execution were not run. Design-Signed-Off-By: Codex (GPT-6); design-review=6aeb

Model preparation can fail with
'tileiras' compiler not foundwhen the preparation environment hascuda-tilebut no system TileIR compiler. FlashInfer declares the Python package without its compiler extra.Add
cuda-tile[tileiras]==1.6.0to Ignition'sprepareextra and regenerateuv.lock, souv sync --locked --extra prepare --extra testinstalls the CUDA 13.2.86 compiler packages. Preserve all existing locked package versions and document the compiler requirement in the preparation guide.Validation:
uv lock --check --offlinepasses.tileirasandptxasboth report version 13.2.86.testextra.The full
prepareinstallation plan fails on Windows becausenccl-extensions==0.1.0has no Windows distribution; the parent commit produces the same failure. Windows preparation uses the separate environment described indocs/windows.md. Native Windows serving does not depend on these Python packages.Complete model preparation, GPU execution, and native Windows compiler execution were not run.
