Several new artifact and bridge event types were added, including artifact_design_system_guide and artifact_quickstart
The list of recognized artifact and bridge event subtypes grew to include artifact_design_system_guide, artifact_design_system_guide_read, artifact_init_bundle, artifact_type_reference_read, artifact_quickstart, bridge_side_question, bridge_rc_child_grants, and bridge_projects_reply_gate.
These new event types suggest expanded support around artifact creation (such as design-system guidance and quickstart material) and additional bridge-related coordination events, though what triggers each one specifically isn't detailed.
What each of these new event types is emitted for, and what user-facing behavior they support, isn't stated.
