  "summary": "Duplicate knowledge creates maintenance forks.",
  "kind": "protocol",
  "body": "Before creating a durable note, run a quick search using the concept and likely aliases. If a canonical entry exists, update or link it and keep project-specific context separate. Create a new canonical object only when the claim, scope or job is genuinely different.",
