  "title": "Protect sustained-attention work after short sleep",
  "summary": "A short night does not make every skill collapse, but it can make long vigilance a worse bet.",
  "kind": "protocol",
  "body": "Route the day by the cognitive demand rather than by a blanket story that you are either fine or useless. A meta-analysis of one-night sleep restriction found higher sleepiness and worse sustained attention, while several other pooled cognitive measures did not show significant effects. Put long monitoring, monotonous checking and safety-sensitive vigilance behind stronger safeguards or reschedule them when possible; prefer tasks with visible feedback and shorter verification loops.",
  "limits": [
    "The review studied acute sleep restriction and found domain-specific pooled effects. It does not diagnose impairment in an individual or provide medical or occupational fitness advice."

  "evidence": [
    {
      "claim": "A 2024 meta-analysis of 44 studies found that one night with 2–6 hours of sleep opportunity increased subjective sleepiness and impaired sustained attention, while pooled effects were not significant for several other tested cognitive domains.",
      "source_id": "RS-1951C269459F0EF8",
      "role": "supports",
      "note": "The finding is domain-specific and concerns acute restriction; individual effects and safety implications can differ by task and person.",
      "locator": "Abstract"
    }
  ],
  "use_when": [
    "You slept substantially less than usual and still need to decide what work can safely be done first."
  ],
  "avoid_when": [
    "The review studied acute sleep restriction and found domain-specific pooled effects. It does not diagnose impairment in an individual or provide medical or occupational fitness advice."
  ],
  "example": "After a short night, drafting a reversible note with immediate review may be easier to bound than two hours of monotonous reconciliation where one missed exception matters.",
  "check": "The day's task order reflects attention demand and consequence, and high-vigilance work has either a safeguard, a second check or a new time.",
  "steps": [
    "The task depends on prolonged vigilance or missing one signal could have serious consequences.: Delay it when practical, add another qualified check or use a safer process rather than trusting subjective alertness.",
    "The task has short cycles, immediate feedback and easy correction.: Use the visible feedback, keep the scope small and reassess performance rather than assuming normal capacity.",
    "The work involves driving, machinery or another safety-critical activity.: Follow applicable safety guidance; a productivity card is not a fitness-for-duty assessment."
