/**
 * The connection registry this host installed, for provider code that is not
 * given one.
 *
 * A `WorkflowRunDatabase` handle is a lease on an authoritative connection, and
 * everything that writes beside a caller's transaction needs the registry that
 * issued it. Most provider code is handed that registry directly, because it is
 * created where the provider is installed. The suspension controller is not: it
 * is created by the trusted host around one execution, from a handle alone.
 *
 * So the registry travels under a stable contextual name — and what travels is
 * an opaque token, never the registry. The token is meaningless without the
 * private map that resolves it, so a scope that reconstructs the name selects
 * nothing, and a registration closed with its installing scope stops resolving.
