What
When creating an artifact from a type is not available in a cloud session, the refusal now points you at a local alternative ("a skill or a file is fine for that") instead of only saying nothing was created. Failures also report a category alongside the message.
Details
The failure payload carries files_error (the message) plus an optional files_error_kind naming the class of failure.
A new preamble warns that published artifacts do not honour a <base href> written by the author.
Evidence
so nothing was created; do not retry here
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
