Module 3 builds practitioner-level fluency with the critical runtime tools and code templates required to operate production-grade autonomous systems. You will learn the tooling that enforces boundaries, lifecycle determinism, contract-wrapped tool execution, invariant detection, and traceability. You will also work with minimal code templates that demonstrate how ARE enforces governance, safety, and deterministic execution in real deployments. This module is highly operational and directly tied to real-world incidents in the field.
