Jun 1, 2025June 2025 monthly summary for lantanagroup/link-cloud: Implemented end-to-end enhancements for patient data handling and deserialization, with a focus on reliability and business value. Delivered: NDJSON export and persistence of patient reports to Azure Blob Storage with payload URI generation; validation of patient bundles by reading from Azure Blob Storage (ABS) for efficiency; support for unknown FHIR resource types in deserialization with a generic Resource model and improved performance via cached JsonSerializerOptions; and cross-platform stability by enforcing LF line endings (gitattributes). These changes improve data submission speed, reduce REST round-trips, decrease deserialization errors, and improve developer experience and cross-platform consistency.
