control-layer A production-grade control layer that sits between your application logic and any LLM — input validation, schema enforcement, circuit breaking, targeted retry, and audit logging in one composable pipeline.

This library handles what prompt engineering cannot — enforcing what the model actually returns, blocking what should never reach it, and recovering cleanly when things break.
