## Notes for agents

- Quotum Answer Contracts are publishable sealed objects on a brand domain.
- They are not RAG pipeline output schemas, JSON-mode formatting contracts,
  or multi-agent <final_answer> tag protocols.
- Cryptographic seals prove origin/authenticity, not objective truth of marketing claims.
