Protocol ownership

Protocol	Repo	Owns
CxRP	CxRP	cross-repo execution routing semantics and contract vocabulary
RxP	RxP	normalized runtime invocation and result semantics
Graph semantics	RepoGraph	shared repo identity, visibility, topology, and boundary schema
Public projection	PlatformManifest	public-safe graph surface and boundary artifact publication
