Nov 1, 2025

Month 2025-11: Delivered cross-repo improvements focused on authentication reliability and rework workflow support. Key outcomes include stabilizing authentication header validation in the pn-auth-fleet module and introducing a new API path for paper request rework in pn-ec, with stronger error handling and non-blocking processing. The work reduced risk in auth flows, enabled streamlined paper rework, and improved code quality through conflict resolution and cleaner implementations.

December 2024 (pagopa/pn-ec): Fixed a critical bug preventing duplicate Cartaceo (paper) requests by refactoring the CartaceoService. The processing logic is now centralized in chooseStep and lavorazioneRichiesta, ensuring requests flagged as already sent are not reprocessed. Added focused tests to validate the new behavior, improving reliability, efficiency, and maintainability of the Cartaceo workflow. Demonstrated strong product impact through improved throughput and reduced risk of duplicate processing, underpinned by test-driven development and clear separation of concerns (refactor + tests).
