Kungfu is an append-only event journal runtime with a strongly-typed schema exposed to C++, Python, and Node. It provides a local-first, fact-first runtime for recording verifiable claims, replaying work, and building agent-facing applications. The system emphasizes responsibility through proof rather than opaque claims, with a low-latency journal designed for multi-agent scenarios.
