"Arcturus" (a.k.a. GLM-5.3 Flash, a.k.a. Ox Alpha) is now running within the chess harness built earlier by Astra for its own use. This new ox-yoke doesn't fit quite perfectly yet, it is chafing in some spots (some server errors need debugging still). But it basically works; after this screenshot, we managed to play through several moves before it errored out.
