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, no stored row is rewritten or deleted, and no exported declaration is added, removed or narrowed, so there is nothing for `objectstack migrate meta` to rewrite. What narrows is the accept set of sixteen of this package's own routes, and of the exported bridges eleven of them mount, for one input: a body declared as JSON that does not parse, which used to be read as no body. The remedy is in the requests a client sends, never a rewrite of a package source or a stored row. The other categories are closed on facts: the package publishes (not unpublished); no ADR-0087 id is named or touched (not registered or already-registered); and nothing exported is removed or narrowed, every signature is unchanged (not runtime-interface-only, type-surface-only or runtime-export-retired).
