ADR-0087 exemption (no-migration-prescription): No metadata moves: no spec key, authorable spelling, object definition or stored shape is added, removed, renamed or re-shaped, and no exported declaration is removed or narrowed, so there is nothing for `objectstack migrate meta` to rewrite. An authored template body's own markup renders exactly as before; what changes is how the renderer encodes a hole's VALUE in the html and mjml faces. The remedy is an author's choice — put the markup in the template body instead of a payload value — never a rewrite of a stored row or a package source, and stored `sys_notification_template` rows are not touched. The other categories are closed on facts: the package publishes (not unpublished); no ADR-0087 id is named or touched (not registered or already-registered); and nothing exported is removed or narrowed (not runtime-interface-only, type-surface-only or runtime-export-retired).
