CMAB experiments should not use UPS for sticky bucketing because: - UPS maintains decisions across the experiment lifetime without considering TTL or user attributes - This contradicts CMAB's dynamic nature which requires fresh decisions based on current context Changes: - Modified get_variation() to skip UPS read for CMAB experiments - Modified get_variation() to skip UPS write for CMAB experiments - Added 4 comprehensive unit tests to verify CMAB exclusion and non-CMAB regression Test Results: - All 52 decision_service tests pass - New tests verify CMAB doesn't use UPS - Regression tests ensure non-CMAB experiments still use UPS Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>
