# Kavach

> Open-source (Apache-2.0) flight recorder for journal-driven services: records every input, clock read and random read, and when a step panics or breaks an invariant writes a .kavach fixture that replays the crash byte for byte with no broker, database or network, then rejects narrow fixes that fail across perturbed variants. SDKs in 12 languages plus agent skills; pre-alpha.
