Artifacts not in their notes

Claude now explains how to activate an artifact comment thread it cannot resolve.

@claude
What

Guidance on artifact comment threads changed. A thread is activated by replying with Send to Claude or by mentioning @claude, and when Claude cannot resolve a thread that was never activated it must leave it open and tell you that a writer can send it to Claude or resolve it in the artifact view. The old wording just told Claude to leave the thread for the commenter.

Evidence

reply on it with Send to Claude

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
