evaluate() and expandIfStatementsAndEvaluate() now return std::expected<void, QString>: the error message is always part of the return value rather than an optional out-parameter, making it impossible for callers to silently discard errors. Update RimGridCalculation and RimSummaryCalculation to use evaluateResult.error() instead of a separate errorText variable.
