ADR-0087 exemption (no-migration-prescription): Nothing metadata-shaped moves: no spec key, no Zod schema, no `packages/spec` declaration, no export, no config field and no stored row changes spelling or shape, and a stored flow definition is byte-identical before and after — `objectstack migrate meta` has nothing to reach. What moves is the reference identity of the object one runtime seam hands a flow. The consumer note below names the supported node for writing a record; it prescribes no rewrite of any authored artifact, and the code it could affect is a stack author's own registered function body, which the metadata upgrader cannot see.
