What

The explanation shown when file_path or favicon is missing dropped its type-specific wording and now just notes that this would create a new artifact, and that passing a url updates an existing one and keeps its icon.

Evidence

a new Artifact — to update an existing one instead, pass its url (its icon is kept)

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
