In some embodiments, a method receives a change to data stored in a repository. An artifact that is generated based on the change to the data failed a validation. The method analyzes the change to the data via a model to generate a set of adjustments. The model is trained to output adjustments for the artifact to generate a set of adjusted artifacts. The method determines an adjusted artifact that is associated with an adjustment in the set of adjustments that passes the validation. The adjusted artifact is output as a validated artifact.
