May 1, 2025May 2025 monthly summary for NHSDigital/eligibility-signposting-api focused on reliability, maintainability, and business value. Key features delivered: NVL/default to operators and improved NVL matching with extended OFFSET/date operator support, supported by tests (commits including ELI-236 - Add NVL Default to Operators; non-greedy NVL matching; OFFSET tests; final operator changes). Live Iteration Handling: evaluate only live iterations and add tests for campaigns with no live iteration (commits: 64916156; 62e90f80; 8a5bcfc4). Data Model Simplification and Safety: simplified structures, added cohort_label, ignore unrecognised data, refactor eligibility_rows_builder naming (commits: 27a40f39; c5ca1733; 036d3767; baf6f9c2; 1c5dea97). Eligibility Rules - Filter and Suppression and Rule Priority: implement filter/suppression functionality and refactor/expose calculator with priority evaluation; align tests (commits: 9ef9abfd; 99b2e16e; 0daff15b; 5f1379b2; 18abbf93; 3d7099a2; 08d99460; a3e63b2d; 9afdae76). Testing Enhancements: eligibility rows fixture; cohort/campaign & non-base-eligible tests; enhanced test utilities (commits: 87e632e6; aa21b756; 75c8e210; 7ab18fac; 5377ed2e). Documentation and Maintenance: context diagram in README, missing link fixes, version bumps (commits: 8baefe83; ddbe5e40; 5b072204). API surface and readiness: ELI-204 API path update and subsequent version bumps (commits: 29bc6856; 105df5e9). NHS number faker provider and improved visibility of PersonDetailProvider; added missing gender values (commits: 679961d5; 19a29976).
