 <!-- adr-0087: not-required (runtime-export-retired @object-ui/plugin-designer#useConfirmDialog, @object-ui/plugin-designer#VersionHistory) the retired operands are a React hook and a React component in a published ui package's entry that nothing in the workspace or in hotcrm imported; no packages/spec schema, registered node type, ADR-0087 conversion surface or stored shape names them, so there is nothing for `objectstack migrate meta` to rewrite -->
