  "summary": "Sometimes safety is partly an environmental setting.",
  "kind": "protocol",
  "body": "Identify the task phases where distraction is unusually costly and make a temporary interruption rule: physical sign, status mode, closed chat, role coverage or separate workspace. Keep emergency communication available. End the protected state when the fragile phase is complete so the exception does not become permanent isolation.",
  "limits": [
    "Do not use focus protection to block needed peer review or make a single person the uninterruptible bottleneck."
