  kind: 1111,
  content: "<comment text>",
  tags: [
    // Root scope - uppercase tags
    ["A", "<kind>:<pubkey>:<dtag>", "<relay>", "<author-pubkey>"],
    ["K", "<kind>"],
    ["P", "<author-pubkey>", "<relay>"],
    
    // Parent scope - lowercase tags  
    ["a", "<kind>:<pubkey>:<dtag>", "<relay>"],
    ["k", "<kind>"],
    ["p", "<author-pubkey>", "<relay>"],
