  "summary": "A knowledge base needs state, not only storage.",
  "kind": "protocol",
  "body": "For notes that can become obsolete, use a small status vocabulary such as current, provisional, superseded or needs-review. When state changes, preserve the reason or link to the replacement instead of deleting history that may explain past decisions.",
  "limits": [
    "Do not create elaborate lifecycle states for stable low-stakes notes; add state where outdated use would matter."
