A node instance decides which of its ports are exposed
One chain answers "is this port exposed?" everywhere it is asked: for edges and for the workflow's exposure map alike.
The rule
Normative: this is the rule
- A port's effective exposure on a node is the instance's own
config.ports[].exposedvalue where the instance sets one, and otherwise the port'sexposedByDefaultin the node type's metadata. - Exposing a port on the instance therefore makes an edge to or from it legal that would otherwise be refused.
