# Vendored DS4 Metal boundary These files are a one-time snapshot of the DS4 Metal boundary from commit `efdadd41e20134af4f3381e1ed90e96fe4faef6f`: - `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.
