h5i - Next-Gen AI-Aware Git

Meet h5i: The Git sidecar for the AI age. While Git tracks code diffs, h5i versions the AI’s "Reasoning" (Observe-Think-Act) alongside it. Unlike existing tools, h5i structures AI logic as a DAG linked to Git commits, allowing models to instantly restore context after session resets. It stands out with advanced compliance features like "Blind Edit" detection, uncertainty heatmaps, and prompt-injection scanning to ensure AI-generated code is traceable, safe, and reliable.
