FWIW, the suggested `mlir::emitError` reports its error but doesn't stop lowering. With `fold.cpp` changed locally to keep NOTIFY=, compiling the program from #230633 prints this error. Compilation still succeeds, and the generated EVENT POST ignores NOTIFY=. `fir::emitFatalError` would stop lowering.
