Summary
Exclude CMAB (Contextual Multi-Armed Bandit) experiments from User Profile Service (UPS) to ensure dynamic decision-making that respects TTL and user attributes.

UPS maintains decisions across the experiment lifetime without considering TTL or user attributes, which contradicts CMAB's dynamic nature. CMAB experiments need to make fresh decisions on each call to respond to changing contexts.
