Cunxi Yu, Chenhui Deng, and Nathaniel Pinckney's HORIZON is a self-evolving agent framework driven by a Markdown-based harness that iteratively mutates and tests a whole codebase. The interesting part isn't the hardware. It's that the repo-as-substrate-for-evolution pattern is exactly how modern coding agents already operate, which makes the approach transferable to general software automation. If you're building autonomous coding loops, the explicit Markdown harness design is worth reading even if you never touch silicon.
