Artifact comment auto-reply pipeline reworked to track which comments were already seen or sent to Claude

What

The internal pipeline that automatically reacts to comments on Artifacts (documents, apps, or other content Claude generates that can be shared and commented on) has been reworked. It now:

  • Tracks which comments have already been seen or already sent to Claude, filtering out ones that were already handled or re-fired.
  • Records who authored each comment.
  • Only reuses previously fetched page content from cache when that content is going to be quoted to an audience and passes an additional check; otherwise it re-fetches.
Why

This should reduce duplicate or stale auto-replies to Artifact comments by making the system aware of what it has already processed, and by being more careful about when cached content is safe to reuse.
