+Both are also built-in Providers in OneAgent. Sponsorship does not change which
+Provider is recommended or how one is verified: every Provider is probed against
+the protocol its Agent actually speaks, and the built-in list is ordered in
+`providers.lock.json` independently of any commercial relationship. See
+[providers.lock.json](providers.lock.json) for each entry's declared
+relationship and disclosure.
