  "title": "Repeat the task, then change the task",
  "summary": "The second attempt can free capacity; the third should test transfer.",
  "kind": "protocol",
  "body": "Repeat a meaningful task after reviewing the first attempt so the learner can improve accuracy, complexity or fluency with less planning cost. Then change the prompt, audience, data or communicative purpose while preserving the target skill. Improvement only on the identical script is useful rehearsal evidence, not yet evidence of broader language control.",
  "limits": [
    "Too much identical repetition can turn retrieval into script memory. Use repetition to create capacity, then demand transfer."

    {
      "claim": "Task-repetition research finds that repeating a communicative task can improve dimensions of L2 performance, while the size and pattern of effects depend on the task and repetition design.",

      "role": "supports",
      "note": "Immediate improvement on a repeated task can include task familiarity and does not by itself prove transfer to new topics.",

  "use_when": [
    "A speaking or writing task was difficult enough that one attempt mostly exposed planning and retrieval limits."

  "avoid_when": [
    "Too much identical repetition can turn retrieval into script memory. Use repetition to create capacity, then demand transfer."
  ],
  "example": "Explain a migration issue, repeat the explanation after feedback, then explain a different incident to a non-technical stakeholder.",
  "check": "At least one improved feature appears in the changed task, not only in the repeated version.",
  "steps": [
    "Perform the task without a script.",
    "Review one or two target gaps.",
    "Repeat the same task once.",
    "Change a meaningful condition.",
    "Compare whether the improvement survives the changed task."
