Jun 1, 2025June 2025 performance summary for 1024pix/pix: API naming and versioning improvements, core calibration infrastructure, data model refactors, and reliability enhancements. Delivered targeted API rename from scoreComplementaryCertifications to scoreComplementaryCertification with a v2-oriented use case naming to support future enhancements. Established calibration data model and framework calibration support by introducing active_calibrated_challenges and calibrations tables, enabling injection of calibrated challenges into existing frameworks, and iterating the active_calibrated_challenges schema with migrations. Refactored certification-frameworks-challenges to use complementaryCertificationKey and added a data-preserving migration. Improved script error handling to capture, log, and rollback only on genuine failures. Updated PDF snapshots for certificate testing to reflect current outputs. These changes lay groundwork for scalable calibration workflows, clearer API contracts, safer migrations, and more reliable testing.
