What
When a permission check for an artifact action cannot complete, the action is still refused, but the explanation now depends on where it happened: inside the shared cowork frame it keeps the consent-floor wording, and outside it reads as an asset-action message instead of a misleading cowork one.
Evidence
Artifact asset actions fail closed when their permission check cannot complete
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
