| 67 | **Core Data Model ERD** - Shows primary business entities and their relationships. Claims have Evidence (sources supporting/refuting) and Scenarios (different contexts for evaluation). Each Scenario is assessed by Verdicts (conclusion about the claim in that scenario context). Evidence comes from Sources (with track records). Verdicts track changes through the Edit entity like all other entities. Claims include denormalized cache fields for performance. Most entities created/edited by AKEL automatically. See [[Audit Trail ERD>>FactHarbor.Specification.Diagrams.Audit-Trail-ERD_Mermaid.WebHome]] for edit tracking relationships. |
