  "summary": "Checked the supplied Ai2 and PNAS excerpts, executed outputs, and both charts. Added independent technical evidence, corrected the description of TutorMoments, and aligned the notebook’s interpretation with the observed ties, saturation, and threshold effects. The code is unchanged.",
  "changes": [
    "Added the PNAS randomized trial as a second independent open source, distinguishing its real-student outcomes from TutorMoments’ simulated replays.",
    "Clarified that teachers identify moments calling for scaffolding or rigor; over-scaffolding is an evaluated tutor behavior, not a desired response.",
    "Revised the title and description to emphasize the toy model’s measurement limitation rather than promise a tutoring-policy recommendation.",
    "Limited saturation and noise conclusions to the tested settings, and distinguished the capped skill variable from measured learning or retention.",
    "Replaced the claim that correctness must rise with help with a conditional explanation: automatic correctness favors help at a fixed state, but trajectories also change.",
    "Explained the tied maxima, dashed chart markers, truncated axis, overlapping noise curves, and model-defined frustration rate.",
    "Removed the first-person experiment narrative and redundant closing summary."
