Summary

CMAB experiments should not use UserProfileService (UPS) for sticky bucketing. 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 stored variation lookup for CMAB experiments in the decision service
  • Skip UPS variation save for CMAB experiments after decision is made
  • Add decision reason log when UPS is skipped for CMAB experiments
