ADR-0087 exemption (runtime-interface-only): No metadata moves: no spec key, authorable spelling, object definition or stored shape is added, removed, renamed or re-shaped, so there is nothing for `objectstack migrate meta` to rewrite. Two things change. The security service's probes answer an in-process caller that builds an on-behalf-of execution context in an organization the delegator does not belong to with the refusal its operations already get; the remedy is to build that context in an organization the delegator is a member of, never a rewrite of a package source or a stored row. And the published runtime interface `ExplainEngineDeps`, which has no metadata surface, gains a required member; the channel that reaches an embedder who builds it is the compiler at their own call site.
