[AI-FSSDK] (DO NOT REVIEW) [FSSDK-12262] Exclude CMAB from UserProfileService#2
Conversation
- CMAB experiments now skip UserProfileService for both lookup and save operations - UPS maintains decisions across experiment lifetime without considering TTL or user attributes, which contradicts CMAB's dynamic nature - Added decision reason message when skipping UPS for CMAB experiments - Added comprehensive unit test to verify CMAB excludes UPS Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>

Summary
Excludes CMAB (Contextual Multi-Armed Bandit) experiments from UserProfileService (UPS) to align with CMAB's dynamic decision-making requirements.
Context
FSSDK-12262
CMAB should not use UPS for sticky bucketing because UPS maintains decisions across the experiment lifetime without considering TTL or user attributes, which contradicts CMAB's dynamic nature.
Changes
decision_service.rbto detect CMAB experiments (line 105)decision_service.rbto skip UPS lookup for CMAB experiments (line 106)decision_service.rbto skip UPS save for CMAB experiments (line 167)Testing
when user profile service is available should exclude CMAB experiments from user profile serviceQuality Metrics
