# Vendored DS4 Metal boundary These files track the DS4 Metal boundary audited at commit `8db89fe083ae4d17c9a2428ccd29803d3ae8f577` (2026-08-28): - `ds4_metal.m` - `ds4.h` - `ds4_gpu.h` - `ds4_ssd.h` - `LICENSE` The matching Metal kernels live in the repository-level `metal/` directory. DS4Server builds and bundles this local snapshot; it does not read a sibling DS4 checkout. Rust owns the model, graph, session, sampling, and lifecycle. Objective-C remains only at the platform Metal boundary.
