  "title": "Train accuracy before adding speed when errors are still structural",
  "summary": "Speed rehearses whatever rule is already running.",
  "kind": "principle",
  "body": "First make the decision process accurate enough that common errors are understood and corrected. Then add realistic time constraints and watch whether accuracy survives. If speed pressure revives structural errors, step back to the decision cue rather than simply demanding more repetitions.",
  "limits": [
    "Some domains require early speed–accuracy trade-offs or real-time coordination. Use domain standards rather than a universal accuracy-first sequence."
