Summary\n\nCMAB experiments are now explicitly excluded from UserProfileService (UPS) sticky bucketing. UPS maintains decisions across the experiment lifetime without considering TTL or user attributes, which contradicts CMAB's dynamic nature.\n\n## Changes\n\n- Skip UPS stored variation lookup for CMAB experiments in
get_variation()\n- Skip UPS variation save for CMAB experiments after bucketing\n- Add informational decision reason when UPS is skipped for CMAB experiments\n- Non-CMAB experiments continue to use UPS as before (no behavioral change)\n\n## Jira Ticket\n\nFSSDK-12262
