What
Creating an Artifact from a non-interactive agent run now fails with its own codes, agent_no_credential when no credential is available and agent_credential_refused when one is rejected, rather than the generic no-auth and forbidden messages used for interactive creation.
Details
Selected by the interactive flag on the artifact-create call being false.
Interactive creation keeps its existing messages.
Evidence
agent_no_credential
