Diagram

Your diagram, kept as you sent it: keys we do not model — notes, embedded bricks — come back untouched. The one thing we add is isTarget: true, on any node that does not already say whether a connection may end at it.

We read nodes and connections to check it. A diagram missing either is stored anyway and reported as breaking rules.
