ADR-0087 exemption (no-migration-prescription): The three keys are `@object-ui/types` schema members on objectui's own node face, not an `@objectstack/spec` key, object definition, stored row or stored shape: the spec declares `visibleWhen` as the one conditional-visibility predicate at every layer (ADR-0089) and never declared a `*On` suffix on a page component, so the ADR-0087 registries in `packages/spec` have no entry to write and `objectstack migrate meta` has nothing to rewrite. Each old spelling is refused by name on both faces (the TypeScript compiler, the Zod mirror behind `objectui validate`), and the refusal names the surviving key; that is the same disposition the objectui retirements took when the package merged into this repository (maintainer ruling 28 = B on objectstack#25831). The guidance below is for the author of a page, not for a metadata upgrader. The other categories are closed on facts: the four packages publish (not unpublished); no ADR-0087 id is named or touched (not registered or already-registered); and what narrows is a declared schema key on a published metadata face, not a runtime-only interface, a type annotation or a runtime export (not runtime-interface-only, type-surface-only or runtime-export-retired).
