What so you mean by automated presubmits? Are those „just“ CI checks for static analysis or is there more sophisticated things going on like merging it to a generated branch, deploying it, running all tests in the infrastructure there and more? Can you elaborate a little bit more on this? Or point me to a resource that is doing this?
