What
A new internal function reads an artifact's underlying HTML source, accounting for anchor-file state, and returns a "withheld" result if that source hasn't been published. This is used to decide whether an automatic reply or summary is allowed to proceed.
Why
This stops Claude from auto-replying to or summarizing artifact content that hasn't actually been published yet.
