How does triggering human-in-the-loop approvals satisfy ABA Model Rules requirements?

Kastra enforces triggering human-in-the-loop approvals at the moment of execution and writes a signed evidence record for every action. Auditors get a complete, append-only trail of who attempted what, what policy fired, why the decision was made, and what data was touched. This evidence maps directly to ABA Model Rules, attorney-client privilege controls control families.
