Also reject a LINK/LINKED cell\nwhose last_seqno_recv is above what we ever sent on the set.\n- Correctly copy the MiddleOnly flag from routerstatuses to node\nobjects.\nWithout this fix, the MiddleOnly flag was ignored on non-authorities,\nand\nclients could use MiddleOnly relays for inappropriate roles in onion\nservice circuits. Tracked as TROVE-2026-067.\n- Treat a router descriptor as expired if any of its family certificates\nhas expired. Previously, we incorrectly ignored the expiration time of\nthe family certificate.
