1. User types in editor
2. Editor creates Transaction
3. Transaction converted to CRDTOperation
4. Operation sent to Relay via WebSocket
5. Relay broadcasts to other clients
6. Relay forwards to fork-node for CRDT merge
7. vest-node records proof
8. Other clients receive and apply operation

1. User drags timeline slider
2. TimelinePlugin captures timestamp
3. Request sent to tnp-node
4. tnp-node reconstructs document state
5. Editor displays historical view
6. User can return to present
