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 nature. This update explicitly excludes CMAB experiments from UPS logic.

Changes

  • Skip UPS lookup for stored variations when the experiment is a CMAB experiment
  • Skip saving new variations to UPS for CMAB experiments
  • Add decision reason logging when UPS is excluded for CMAB experiments
