* Ship precompiled eGPU model and camera warps Compile f78ed37d-afad-4dbc-8050-40ea885eedde/12864 through xx/ml_tools/openpilot_compile using the pinned tinygrad version. * Precompile the existing master driving model Use the unchanged master ONNX (SHA-256 6fee5937923c74848df4a63f6239eb6331c6274dd4bdb7a5d6ec0388a8b543d5) instead of updating the trained model. * Compile camera warps on device * Remove obsolete ONNX chunking and big model build check * Chunk model artifacts only during release packaging * Require model and camera warps for Chestnut readiness * Recompile precompiled CPU helpers for the runtime host * Ship the eGPU model with an ARM submission helper * Exempt model pickles from the build product size limit
