Summary

CMAB experiments no longer use UserProfileService for sticky bucketing. This allows CMAB to maintain its dynamic decision-making nature without being constrained by stored decisions that ignore TTL and user attribute changes.

Changes

  • Modified decision_service.rb to exclude CMAB experiments from UPS lookup and save operations
  • Added decision reason to indicate UPS exclusion for CMAB experiments
  • Added comprehensive unit test to verify UPS exclusion behavior

Jira Ticket

FSSDK-12262

Testing

Verified with unit tests. New CMAB UPS exclusion test added to ensure proper behavior.
