It's expected that `verification-metadata.xml` should only be updated with the commits that modify the build. There are some tips how
to perform such updates:

    if (annotation is FirAnnotationCall && annotation.arguments.isEmpty()) return emptyMap()

    checkWithAttachment(annotation.resolved, { "By now the annotations argument mapping should have been resolved" }) {
        withFirEntry("annotation", annotation)
        withClassEntry("annotationTypeRef", annotation.annotationTypeRef)
        @OptIn(UnresolvedExpressionTypeAccess::class)

            val containingFile = (symbol.firSymbol.fir as? FirElementWithResolveState)?.getContainingFile()
            if (containingFile == null || containingFile.declarations.firstOrNull() !is FirScript) {
                // Should be replaced with proper check after KT-61451 and KT-61887
                return false
            }
        }

        val firSymbol = symbol.firSymbol
