    Edit["add / delete / connect"] --> History["in-memory history"]
    Edit --> Validator["shared connection validation"]

This route adds explicit local edit history and shared connection validation to a small workflow. History records add, delete, reset, and accepted connections. It is in-memory page state, not persisted revision storage; reloading starts again.

Validation rejects missing endpoints, self-links, duplicates, connections into inputs, and connections out of sinks. The shared validator also guards control-only cycles; this demo creates data connections, so that is not a blanket ban on every cycle.

See concepts for exact validation scope.
