Each snapshot now detects what kind of change it represents (node add, node remove, connection, parameter, move, mixed) and displays a distinct colored icon on the timeline. Sidebar meta line shows the change type. Existing snapshots without change data gracefully fall back to a faded "unknown" dot. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
