Comment (by arma):

 I added a log message, and node_supports_ed25519_link_authentication() is
 indeed returning 1.

 Theory: *this* descriptor doesn't have an ed25519 key, but a previous one
 did. So in dirserv_single_reachability_test(), "router" doesn't have an
 ed25519 key, but node_supports_ed25519_link_authentication(node) doesn't
 look at router, it looks at node, and node *does* have an ed25519 key,
 from a previous descriptor that we learned it from.
