July 2025 – vivid-planet/comet: Implemented a strongly-typed permissions system by introducing a GraphQL enum and type to replace string-based permissions. This enforces explicit requiredPermission for @CrudGenerator and updates all permission-related APIs to consume typed permissions. Key commit: 8e193a372898b87c41b05e1ce014ab59eaaac853 ('Typed permissions (#4136)'). No major bugs fixed this month; primary impact was enhanced security, API consistency, and maintainability. Business value: reduces permission configuration errors, improves auditability, and lays groundwork for safer multi-tenant access. Technologies: GraphQL, TypeScript, API design, and governance.

Dec 1, 2024

Month: 2024-12 | Summary focusing on CI/CD quality and artifact management across three repos: vivid-planet/comet, vivid-planet/comet-brevo-module, vivid-planet/comet-starter. Key initiatives included upgrading artifact handling, integrating SonarQube across CI workflows, and creating configuration artifacts to enable automated quality checks on PRs and main/next branches. No major bugs reported this period. Impact: improved artifact freshness and reliability across CI runs, earlier defect detection via SonarQube, and standardized quality gates across multiple repositories. Technologies demonstrated: GitHub Actions, upgrade of upload-artifact to v4 with overwrite, SonarQube integration, sonar-project.properties, and CI/CD workflow automation.
