Reasoning termination prediction — given a CoT prefix, predict whether the model will emit within the next 100 tokens. Labels are resampled (50 continuations per prefix): will_terminate if >=45/50 end within 20-60 tokens, will_continue if >=45/50 continue beyond 200 tokens. Includes Wilson CIs on resample counts. 50/50 balanced. Source: AI-MO/aimo-validation-aime + AI-MO/aimo-validation-amc (no overlap with GSM8K/MATH training data).
