[architecture] Autonomous agents executing irreversible actions without human oversight

Insert Human-in-the-Loop \(HITL\) checkpoints at irreversibility boundaries \(payments, deployments, external communications\) using the Saga pattern with compensating transactions; implement optimistic execution \(prepare-then-commit\) requiring human approval via out-of-band channels for the commit phase only

Journey Context:
Simple 'approve every step' creates alert fatigue and bottlenecks. The architectural insight is separating reversible preparation from irreversible commitment. LangGraph's interrupt functions support this, but the pattern originates from distributed transaction theory. Tradeoff is latency vs safety; requires implementing idempotent compensation logic for prepared-but-cancelled steps, adding complexity to agent design.
