3 +This diagram shows how each entity type maintains its version history with parent-child relationships.

5 +== Versioning Architecture Explanation ==
6 +
7 +**Version Chains**:
8 +* Each entity type (Claim, Scenario, Evidence, Verdict) maintains independent version history
9 +* **ParentVersionID** creates directed acyclic graph (DAG) of changes
10 +* Arrow direction: Old version → New version (evolution over time)
11 +
12 +**Version Metadata** (stored with every version):
13 +* **VersionID**: Unique identifier for this specific version
14 +* **ParentVersionID**: Links to previous version (null for v1)
15 +* **AuthorType**: Human, AI, or ExternalNode
16 +* **Timestamp**: Creation datetime (UTC)
17 +* **JustificationText**: Brief explanation of changes
18 +
19 +**Entity Relationships** (dotted lines):
20 +* Claims **have** Scenarios: One claim can have multiple scenario interpretations
21 +* Scenarios **use** Evidence: Each scenario version references specific evidence versions
22 +* Scenarios **produce** Verdicts: Each scenario version gets verdict based on evidence
23 +
24 +**Branching Support**:
25 +* In federated environments, versions can branch:
26 + - Node A: Version 1 → Version 2a
27 + - Node B: Version 1 → Version 2b (parallel branch)
28 +* Both branches preserved for conflict resolution
29 +
30 +**Immutability**:
31 +* Versions never deleted, only superseded
32 +* Historical versions remain accessible
33 +* Complete audit trail for all changes
