What
Loading a published artifact by its short link now asks specifically for the claude.ai sign-in credential rather than "whatever credential is available", so a mismatched login fails predictably.
Details
A mismatch between the artifact's environment and the session's returns a structured env_mismatch code that callers can act on, instead of only recording telemetry at the failure point.
Evidence
claude-ai-oauth
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
