OBJECTIVE\n\nDefine how Devon contracts and schemas must be structured.\n\n---\n\n## 2. CONTRACT PRINCIPLE\n\nEvery meaningful interface must be contract-bound.\n\nContracts apply to:\n- module input\n- module output\n- runtime bridge\n- panel data\n- memory writes\n- validation outputs\n- execution payloads\n\nAudit surface rule:\n- documentation-facing structures may summarize canonical definitions\n- operational-facing structures may expose real runtime evidence\n- no contract may blur documentary summary with operational proof\n\n---\n\n## 3. REQUIRED CONTRACT ELEMENTS\n\nEach contract should define:\n- identity\n- purpose\n- required fields\n- allowed values\n- forbidden values when relevant\n- validation expectation\n- failure semantics\n\n---\n\n## 4. SCHEMA PRINCIPLE\n\nSchemas must prefer:\n- explicit fields\n- deterministic validation\n- traceable identifiers\n- versioned structures\n\nNo vague payloads allowed for governed operations.\n\n---\n\n## 5. ACCEPTANCE CRITERIA\n\nCSS is valid only if:\n- contract fields are explicit\n- schema rule is explicit\n- failure semantics are explicit\n- governed interfaces are covered\n"
