2025-10 monthly summary for navikt/veilarbvedtaksstotte. Focused on reliability, automation, and code quality to improve distribution of vedtak (decisions) and strengthen CI/CD. Delivered a robust retry mechanism for vedtak distribution with a retry table, new repository, and scheduling enhancements to cope with transient failures; added timestamps, limits, and scheduling tweaks to ensure reliable distribution even after temporary outages. Implemented daily scheduled distribution of vedtak, migration V45, and support for future debugging with date-columns. Strengthened testing, CI/CD reliability, and code quality through updated test utilities and container images, post-merge refactors, and SonarCloud improvements. These changes reduce failure to deliver vedtak, shorten recovery time, and boost developer velocity. Key business outcomes include improved reliability and observability for decision distribution, reduced manual intervention in failure scenarios, and a more stable release pipeline that accelerates time-to-value for customer-facing features.
