  "title": "Protect task accomplishment from personal-phone interruptions during the critical block",
  "summary": "The interruption cost may continue after the phone is back in your pocket.",
  "kind": "protocol",
  "body": "A 2025 diary study found personal smartphone interruptions linked indirectly to evening work rumination through lower task accomplishment and frustration. During the most completion-sensitive block, move personal phone access out of the immediate path or batch it to a later window.",
  "limits": [
    "The diary study is observational; causal effects may differ by role and personal context."

  "example": "Keep the phone outside the room during the final 45 minutes needed to finish a report, while family emergency calls still ring through.",
  "check": "The intervention protects task completion and reduces unfinished spillover, not merely phone minutes.",
  "steps": [
    "Identify the block whose completion matters most for later detachment.",
    "Remove or mute nonessential personal-phone interruptions.",
    "Keep an emergency route.",
    "Review whether task accomplishment improves, not just screen time."
