December 2024 monthly summary for CDCgov/prime-simplereport: Implemented a multi-provider provider model to enable facilities to associate with multiple ordering providers, driven by a new facility_providers join table and a default provider. This design reduces data duplication, enables flexible provider selection, and supports multi-provider ordering workflows; in parallel, removed the legacy ordering_provider column to align with the new model. Fixed and hardened ID Verification reminders by ensuring the reminder service honors its configuration, injecting the config directly and gating the sending logic when disabled, with updated tests to prevent regressions. These changes improve data integrity, provider routing, and reminder reliability, contributing to operational efficiency and user trust.
