ACU GYM is a functional synthetic curriculum and experimental evaluation harness for computer-use agents. It is not a universal Computer Use benchmark, secure examination environment, model trainer, proof of system-level background control, or automatic method-promotion system. There is no independent external attestation by default. Results apply only to the missions and execution modes shown.
