Artifact auto-react now forwards teammates' comments, not just the artifact owner's
When Claude Code builds the list of comments to forward for an artifact's automatic reaction feature, it now also includes comments from team members (not just the artifact's owner), when a related setting is enabled. These team-member comments are tagged with source: "unattributed" and get a projectsRow marker plus extra fields. Owner comments are also now cross-checked against a lookup of earlier comments to reuse an earlier authored version and timestamp when appropriate.
Previously only the artifact owner's comments were considered, so Claude could miss feedback left by other team members on a shared artifact; now it can react to comments from the whole team.
What the flag controlling this behavior is called or how it's enabled isn't stated.
