  "summary": "Parallel thinking helps. Parallel uncoordinated production changes often do not.",
  "kind": "principle",
  "body": "Keep live modifications under one Operations Lead or clearly coordinated operations group. Other responders can investigate, propose and validate, but production changes should enter through the same lane so the incident state remains interpretable and rollback ownership stays clear.",
  "limits": [
    "Emergency authority and separation of duties must still follow local security, safety and compliance requirements."
