  "title": "Reduce simultaneous complexity when overload appears",
  "summary": "More struggle is not always more learning.",
  "kind": "protocol",
  "body": "When the learner cannot keep the task state coherent, remove one layer of complexity without removing the target skill. Shorten the case, expose one worked step, split the explanation at a meaningful boundary, or hold one variable constant. Restore complexity after the missing part becomes executable.",
  "limits": [
    "Do not simplify until the assessment demand disappears. Difficulty is useful when it is informative and recoverable."

      "claim": "A meta-analysis found benefits when complex multimedia instruction was divided into meaningful learner-paced segments rather than presented as one continuous unit.",

      "role": "supports",
      "note": "The evidence concerns multimedia instruction; applying it to study blocks is a cautious design analogy.",

  "use_when": [
    "A practice task has so many moving parts that errors multiply but you cannot tell which part is actually weak."
  ],
  "avoid_when": [
    "Do not simplify until the assessment demand disappears. Difficulty is useful when it is informative and recoverable."
  ],
  "example": "If a full architecture case collapses because the integration path is unclear, hold business context constant and solve only the integration decision first.",
  "check": "The simplified task still trains the target skill and has a clear condition for restoring complexity.",
