MnaScript is the payload that turns a generic MnaNode into a one-off custom step without forcing every user-written snippet through the MnaOpRegistry. When the host node's execMode is MnaNodeExecMode::Script the executor writes code to a temporary file, launches interpreter (auto- detected from language when unset) with interpreterArgs prepended, captures stdout/stderr and the exit code, and marshals results back into the node's typed output ports.

Supported languages cover the day-to-day MEG/EEG glue work: python, shell, r, matlab, octave and julia. sourceUri lets the authoring GUI keep a link back to the original file on disk; serialisation resolves that link into code so a shipped project is self-contained. codeSha256 detects tampering between save and load, and keepTempFile is a debug aid that preserves the on-disk script after execution.
