Opening a published artifact link asks for your claude.ai sign-in, so a wrong login fails clearly.
What's wrong with this entry?
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.
- A mismatch between the artifact's environment and the session's returns a structured
env_mismatchcode that callers can act on, instead of only recording telemetry at the failure point.
