Score: 5.0/10 (Innovation: 4, Technical: 5, Documentation: 7, Utility: 4)

This project is a deterministic engine for the I Ching (Liù Yáo) divination system that generates structured hexagram charts from a cast and timestamp using classical rules, cross-validated against other implementations. It is interesting for its rigorous approach to correctness through differential testing and avoidance of AI or network dependencies, making it a reliable reference for a niche domain.

Target audience: backend devs, data engineers
