Unavailable graph node

The node's exact kind/version is unavailable, so domain validation or material projection cannot interpret it. The graph retains the node's original payload for inspection and repair.

#Common causes

• The plugin supplying the node kind or its saved version is absent from NodeRegistry.
• A material graph contains a node kind or custom function that its material adapter does not recognize.

#Fixes

• Register or install the implementation for the exact kind/version named in the message.

• Replace the unsupported node with a supported one using graph.node.add, reconnect its consumers, then remove the old node with graph.node.remove.
