During March 2026, Systemvetaren focused on stabilizing the plugin manifest pipeline for the grafana/grafana-plugin-sdk-go repository. They addressed a backend issue where frontend dependencies in node_modules polluted the manifest by implementing a root-level exclusion, ensuring only relevant Go files were included. Their approach preserved nested directory structures while preventing unnecessary files from inflating the backend manifest. Systemvetaren also improved test reliability by fixing errcheck and gosec lint errors, introducing test helpers, and updating file permissions to align with security best practices. Their work demonstrated depth in Go, backend development, and testing, resulting in a more maintainable and secure codebase.
