Which two design goals are MOST important for human-in-the-loop agent systems in regulated workflows?

In regulated workflows (e.g., finance, healthcare), accountability, transparency, and safety are non-negotiable. A human-in-the-loop (HITL) system must therefore include "review checkpoints for human approval" (A) to ensure a human expert can verify and authorize critical decisions or actions before they are executed. For this review to be effective, the system must also provide a "clear explanation of agent actions" (B), detailing the reasoning and data used. This explainability is fundamental for trust, auditing, and regulatory compliance.

C. Complete removal of audit trails is the opposite of what is required for regulatory compliance and accountability.

D. Automatic execution without oversight contradicts the core principle of HITL and is unacceptable in high-risk, regulated environments.

E. Hidden decision logic prevents human oversight and auditing, making the system opaque and untrustworthy.

The publication emphasizes that for AI systems to be trusted, especially in high-stakes domains, they must be able to explain their decisions to human users.
