MnaNode is the executable counterpart to a MnaFileRef: where the latter records a derived artefact, the node records how that artefact is produced. The opType string is resolved against MnaOpRegistry to obtain the MnaOpSchema (and, for built-in ops, the implementation function) used by MnaGraphExecutor; attributes provides the per-call parameter values validated against that schema.

The execMode field selects one of four executors: Batch (default, file-in/file-out), Stream (live MNE Scan plugin), Ipc (delegates to an external binary via ipcCommand / ipcArgs / ipcTransport), or Script (inline MnaScript run by an interpreter). Each mode reuses the same node fields, so a pipeline can mix all four without structural changes.

verification carries pre/post checks, explanation text and the full MnaProvenance snapshot captured at execution time; combined with toolVersion, executedAt and the dirty flag this is what makes MNA pipelines reproducible and supports incremental re-execution after a parameter edit.
