You'll notice
The verify tool now rejects url-less calls made on behalf of delegated observation agents
What
The verify tool, used to check a published artifact, now blocks calls that leave out the url parameter when the call comes from a delegated-observation agent context. Previously there was a fallback that would check the most recently published artifact if no url was given; that fallback is not available to this kind of agent, so the call is now refused with a message explaining that the artifact url must be passed explicitly.
Why
This prevents a confusing failure where a delegated-observation agent would rely on a fallback that doesn't actually work for it, and instead gives a clear, immediate error telling it to pass the url directly.
