/**
 * Where one version of a module's `telo.yaml` can be read from the hub's static
 * manifest cache, or `null` when this ref is not addressable there.
 *
 * This is the read path an upgrade check uses to ask a candidate version what
 * runtime it requires: a plain CORS GET of a single small file, no transport
 * protocol and no artifact payload, so it works identically from a browser and
 * from an extension host. The `fetch` itself stays with the host — everything
 * in this package leaves the network to its caller.
 *
 * A ref the cache cannot address (a registry ref, whose origin this side does
 * not know; a URL with no version segment) returns `null`, which the caller
 * reads as "not known" and never as "incompatible". Losing the check for those
 * refs is the honest outcome: the manifest is still gated at load time.
