  "summary": "A queue with invisible shortcuts is not the queue people think they joined.",

  "limits": [
    "FIFO is not appropriate for every clinical, safety or business priority. Use an explicit suitable policy rather than a mechanical universal rule."

Claim limit: Urgent or safety-critical exceptions require an explicit appropriate policy.\nSource access: selected_html_passages; accessed on: 2026-09-17; inspected sections: [\"Definition and controlled queue\"].\nAgent scope review, 2026-10-11: LEI FIFO describes a queue ordering convention.

  "checklist": [
    "Define the normal ordering rule for comparable work.",
    "State which conditions legitimately override that order and who decides.",
    "Record why an item was overtaken and when it will be reconsidered, so exceptions do not become permanent neglect."

  "example": "A support queue normally follows arrival order within a service class, while genuine outages use a visible urgent route. Personal familiarity is not a secret third route.",
