Every MNA file, port and node is tagged with a small set of controlled vocabularies that downstream tooling — schema validators, graph executors, GUI editors — uses to dispatch on without parsing strings ad-hoc. Centralising them in one header guarantees that the JSON/CBOR serialisers, the op-registry loader and the executor all agree on the canonical spelling.

MnaFileRole classifies the semantic purpose of a file within a project (Raw, Forward, Inverse, Covariance, …) so a viewer can pick the right reader without sniffing magic bytes. MnaDataKind describes the runtime payload travelling through a graph port (FiffRaw, Epochs, SourceEstimate, RealTimeStream, …) and is what MnaGraph::validate uses to reject incompatible connections. MnaPortDir and MnaNodeExecMode (Batch/Stream/Ipc/Script) complete the surface needed by the graph executor.

The inline xxxToString / xxxFromString helpers are the single source of truth for serialisation; both spellings (CamelCase from the C++ side and snake_case from the JSON side) are accepted on read to keep the format human-authorable.
