THE CHOICE IS BEHAVIOUR-PRESERVING, WHICH IS THE POINT: on a multi-provider box (host + video + cutdown, i.e. every deployed studio) these seven ALREADY do not route today, because no app declares them and studio.mjs's sole-provider fallback needs exactly one provider. Declaring them here would ENABLE something currently unreachable — a policy change smuggled inside a format migration. A migration changes where a fact is written, never what the product does. THE SCOPE QUESTION IS GENUINELY OPEN and is NOT settled by this file: OQ-5 excluded the note verbs, but it was ruled under the threat model that Ruling 15 later RETRACTED, and that retraction says rig-injection is a FEATURE on a trusted box. So the exclusion rests on a withdrawn premise and the inclusion has never been ruled on its own merits. Routed rather than decided here.",
