Aug 1, 2025August 2025 — Masslight/ottehr: Implemented a critical Date of Service alignment fix in Encounter Creation to improve data integrity and downstream reporting. When a service line lacks a dateOfService, the service date is now populated from the appointment start date. If a service line already specifies dateOfService, the logic now avoids duplicating it, with a clarifying inline comment added to prevent sending dateOfService in such cases. This change preserves existing data when explicitly set and prevents conflicts between appointment and service dates.
