Summary

CMAB experiments should not use UserProfileService (UPS) for sticky bucketing because UPS maintains decisions across the experiment lifetime without considering TTL or user attributes, which contradicts CMAB's dynamic decision-making nature.

Changes

  • Skip UPS lookup for stored variations when the experiment is a CMAB experiment
  • Skip UPS save after variation assignment for CMAB experiments
  • Add decision reason logging when UPS is excluded for CMAB experiments
