Detailed Description

The event block a Custom graph node receives, and the callback types that take it.

The graph has routed MIDI for a long time: gather_node_midi fans inbound events into per-node scratch for every node before the executor dispatches on binding kind, and a Processor wrapped by add_processor_node already consumes them. A Custom node was the one graph citizen whose binding never handed that scratch on. These types complete that lane; they do not add MIDI to the graph.

The block is a struct rather than a pair of arguments so that a later transport-aware or automation-aware event node is a new member here, not a fourth callback pair on CustomNodeType. It lives in its own header because custom_node_type.hpp is a reviewed public surface whose byte hash gates the capability fingerprint; keeping the vocabulary out of it holds that file's growth to the two callback members themselves.
