ADR-0087 exemption (no-migration-prescription): Nothing authored moves: no key an authoring door accepts changes its spelling, type or legality, because the four keys are console state the authoring doors refuse by name. The only producer, objectui's console, writes none of the values now refused (census at the `.objectui-sha` pin: a boolean pin, an integer reorder index, the marker as `true`, and `visibility` only carried forward from a stored value). So `objectstack migrate meta` has no mechanical rewrite to perform; a stored row holding a refused value is repaired by correcting it or deleting the key. The other categories are closed on facts: `@objectstack/spec` publishes (not `unpublished`); no ADR-0087 id is minted here or pre-dates the base to cover this (not `registered` / `already-registered`); and a Zod schema's accept set changes, so neither `runtime-interface-only` nor `type-surface-only` applies.
