Running on Zero

checkpoint selection: dropdown of the newest shipped checkpoints (step, bytes, val bpb, arm availability), any of them runnable WITH or WITHOUT the arm. One model is built and ZeroGPU-packed at import; switching copies new values into those same tensors (no second model, no lazy .to(cuda)) and re-verifies anchor provenance on every arm switch — an arm is never attached to a core it was not trained on. Default stays the pre-anneal exhibit pair (51,882) where core-only still shows an unconditioned model; post-anneal checkpoints carry an honest note that their bare core already chats. Verified locally: 51882+arm chats, 51882 core-only gives base continuation, armless checkpoints fall back to core-only cleanly
