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 decision-making nature. This change excludes CMAB experiments from both UPS lookup and UPS save operations.

Changes

  • Skip UPS stored variation lookup when experiment has CMAB configuration
  • Skip UPS variation save when experiment has CMAB configuration
  • Add decision reason logging when UPS is skipped for CMAB experiments
  • Add unit tests for CMAB/UPS exclusion behavior and non-CMAB regression
