### Guardrails are connectors, not gates

- Summary:     In a regulated enterprise, treating guardrails as a wiring concern rather than a review step changes who owns safety — and when.

### RAG was the beachhead. RNA is the architecture.

- Summary:     Retrieval-augmented generation taught enterprises how to feed context to models. Reasoning-augmented architecture is what comes next — and the migration touches more seams than most teams expect.


## Topics covered

The notebook focuses on applied enterprise architecture for the agentic AI era:

- Guardrail-first multi-agent systems
- Reasoning-augmented architecture (RNA) and the migration path from RAG
- Agent-based identity management
- Edge agentic systems and policy-governed intelligence
- Self-healing recovery patterns for agentic degradation
- Scalable causal tracing and reproducible episodes

Many posts are commentary tied to peer-reviewed IEEE conference papers by the
same author; each such post cites the paper and links the DOI.
