Self-contained x86-64 ELFs compiled by the Alpha compiler from one.alpha closure per system/target pairing. Each drives an NVIDIA GPU directly through the RM/UVM interface; there is no CUDA, Python or framework in the executable. They train, resume from a checkpoint and predict through the versioned text-artifact request protocol. manifest.json is the authority for the current sha256 of every file. Only the RTX 3090 pairings have been run on physical hardware.
