The implementation keeps two parallel QMap members — one mapping path strings to literal QVariant values, the other mapping target paths to their MnaParamBinding definitions. MnaParamTree::evaluate iterates over registered bindings, fires those whose trigger condition is met for the supplied execution-context results map, calls MnaParamTree::evaluateExpression to compute the new value via the embedded expression evaluator (with ref("…") look-ups resolved against both the param store and the execution results), writes the result back into m_params and returns the list of paths whose values actually changed so the executor can mark downstream nodes dirty.
