MnaParamTree is the second authoritative source of node attribute values — the first being a node's own attributes map. Where the latter holds the literal value typed by the user for a single operation, the param tree expresses values that are either reused across many nodes (e.g. subject/fsdir) or computed from other values via MnaParamBinding formulas resolved at execution time.

Paths are slash-separated and conventionally namespaced by node id (bandpass_01/lowcut, bandpass_01/highcut), letting the executor merge static defaults from the op schema, static overrides from the project, and dynamically bound values into the final resolvedAttributes captured in the MnaProvenance record. evaluate walks all registered bindings whose triggers have fired and returns the list of paths whose values changed, which the executor uses to mark downstream nodes dirty.
