Decision Review Board (DRB)

Purpose

Periodic review of decision drift and quality over time. DRB operates against artifacts and evidence, not opinions.

Normative properties

• Periodic cadence (risk‑class dependent)
• Operates against SB/DR/RB/DRC, not narrative
• Triggers revalidation, adjustments, or EIS activation
