Dec 1, 2025December 2025 deliverables focused on data contract stability and API integration reliability in MRC-Epid-it24/intake24. Implemented preservation of non-camel-case JSON keys by disabling Kysely's automatic camel-case transformation, enabling accurate handling of nested object keys and compatibility with external data contracts. This change reduces integration errors and supports API partners that rely on specific key formats. The effort also included a regression-safe bug fix to ensure keys are not transformed unexpectedly, improving overall API reliability. Result: strengthened data integrity, improved API contracts, and a solid foundation for future key-format flexibility. Technologies: Kysely, TypeScript, JSON key handling, API design, code review and testing.
