Jan 1, 2025January 2025 | Giveth/impact-graph: Reliability and data-quality improvements across core capabilities. Fixed critical email-verification edge case in updateUser to avoid errors when the new email is undefined and ensured verification runs only when the email changes. Enhanced cluster matching reliability and data integrity with cap calculation fixes, robust data insertion, null passport-score handling, improved error reporting, and a refactored service layer for efficiency. Introduced a uniqueness constraint to prevent duplicate cluster matches and added an environment-controlled decommission toggle for safe feature management. Added instant power boosting data validation to filter undefined wallet addresses and missing balance data before processing. These changes reduce user friction, increase data trust in the impact graph, and enable safer feature rollouts.
