Embedded Rust or C Firmware? Lessons from an Industrial Microcontroller Use Case

https://arxiv.org/static/browse/0.3.4/images/arxiv-logo-fb.png

The agent harness belongs outside the sandbox

https://www.mendral.com/blog/multi-player-agents-sandbox/architecture.svg?dpl=dpl_ENQzTXL1wKKUdjmcFVoQoPnV5mRZ
