  "title": "Space review for when the knowledge must last",
  "summary": "A smooth second reading can arrive too soon to tell you much.",
  "kind": "protocol",
  "body": "Plan returns to the material across time instead of concentrating all review in one sitting. Spacing research shows that useful gaps depend partly on how long the knowledge must be retained. Start with a realistic review schedule, then adjust it using actual recall rather than treating a popular interval sequence as a law.",
  "limits": [
    "No fixed set of day intervals is optimal for every learner, subject and retention goal."

    {
      "claim": "Cepeda and colleagues found that the review gap associated with better later fact retention depended on the intended retention interval.",

      "note": "The authored scheduling questions are an application, not a validated individualized spacing algorithm.",

  "example": "Preparation for an assessment in several weeks needs returns across those weeks, not seven rereads tonight.",
  "check": "The schedule contains delayed attempts, and those attempts influence later review.",
  "steps": [
    "Name when you expect to need the material again.",
    "Schedule a later attempt without the answer visible.",
    "Use the result to decide what needs another review or renewed explanation."
