Remote CISPO on GSM8K

Hypothesis

CISPO minimax is reachable on the public learner API; hosted Optimizers does not yet submit CISPO.

Verdict

Hosted Optimizers does not accept CISPO submissions. The hosted CISPO lane targets Banking77 or Craftax, not GSM8K.

Confidence

high

Why

Authenticated startup probe succeeded. Kernel CISPO remains local synth-mlx-rl; that lab was paused.
