Kage, verification and freshness for Google's OKF agent memory

Kage is a project that provides verification and freshness guarantees for Google's Open Knowledge Format (OKF) agent memory, adopting a file-based, Git-native approach. It is designed for developers and AI agents needing trustworthy, version-controlled memory stores. This is interesting because it aligns with Google's own direction for open, auditable memory standards, ensuring agent data remains verifiable and up-to-date.
