⚡ Key issues to review Simplification The nil check for currentAppStatus.TargetRevisions has been removed, which simplifies the code but assumes that TargetRevisions is never nil. Ensure this assumption is always valid to prevent potential nil dereference. Logic Change The condition for verifyCommit has been changed to check only the length of appProject.Spec.SignatureKeys. Ensure that this change doesn't affect scenarios where gpg.IsGPGEnabled() might return false. Simplification Simplified the condition for adding finalizers by removing the nil check. Verify that replacedTmpl.ObjectMeta.Finalizers is always initialized to avoid nil slice assignment. Condition Simplification The condition for checking diffOptions.revisions has been simplified by removing the nil check. Confirm that this field is always properly initialized. Error Handling Changed error handling from status.Errorf to status.Error which might affect how errors are formatted and displayed. Ensure that this change aligns with the error handling strategy across the application.

I have checked in all the cases where we removed nil check, we actually use slices and let fuction will return 0 and not panic.
