Layer Separation
| Layer | Component | Responsibility |
|---|---|---|
| Model | Semantic Object Graph | Nodes: Object, Evidence, Semantic, Ledger, Seal, Relations |
| Serialization | Semantic XML | Normative wire format (schemas/hext-core.xsd) |
| Layer 2 | HEXT Container | Identity, provenance, integrity, evidence |
| Layer 7 | NVS Observation Plane | Measurement algorithms (external, via observation_ref) |
