What probably matters to youSection of the release
What
Publishing an artifact now has a matching delete action. The tool result reports either "Artifact deleted" or "Artifact was already deleted", and if the model later encounters a deleted artifact URL it is told the link is dead, cannot be restored, and that republishing the same file produces a new URL.
Details
Two distinct result states, so deleting something already deleted is not reported as an error.
The explanatory text for a dead artifact link was rewritten specifically so the model stops trying to revive the old URL.
