- Disable revive exported/package-comments rules (style, not correctness) - Use errors.Is instead of == for pgx.ErrNoRows comparisons - Use errors.As instead of type assertion on validator errors - Use http.NewRequestWithContext instead of client.Get (noctx) - Check resp.Body.Close error return (errcheck) - Run gofmt on files with formatting drift
