  "title": "Treat easy fluency as a signal to change the task",
  "summary": "Comfort can mean competence, or it can mean the practice stopped asking anything new.",
  "kind": "heuristic",
  "body": "If accuracy is high with little effort, first verify retention on a delayed or varied case. If that survives, raise a task demand that matters in real performance: independence, ambiguity, transfer distance or response quality. Do not increase difficulty merely to create struggle.",
  "limits": [
    "Automaticity is valuable for some components. Do not disturb a stable basic skill when the real bottleneck lies elsewhere."

  "example": "A learner can solve the same configuration example instantly. A fresh case with different business rules determines whether to move on.",
  "check": "The next task is harder for a stated performance reason, not because easy practice feels insufficiently serious.",
