+## Model Details
+
+| Property | Value |
+|---|---|
+| Model Type | Hyperbolic text embedding model |
+| Dimensions | 21 (6D hyperbolic + 6D phase + 3D flux + 6D audit) |
+| Geometry | Poincare Ball B^n |
+| Base Model | sentence-transformers/all-MiniLM-L6-v2 |
+| Framework | SCBE-AETHERMOORE |
+| License | Apache 2.0 |
+
+## Intended Uses
+
+- **AI Safety Governance**: Embedding intent vectors for safety classification within the SCBE-AETHERMOORE fleet coordination system
+- **Semantic Retrieval**: Hyperbolic nearest-neighbor search over knowledge base documents
+- **Intent Classification**: Mapping user queries to governance decision nodes
+- **Anomaly Detection**: Identifying out-of-distribution inputs via Poincare Ball boundary proximity
+
+## Limitations
+
+- This model is optimized for the SCBE-AETHERMOORE domain and may not generalize to unrelated NLP tasks without fine-tuning
+- The 21-dimensional Poincare Ball geometry requires specialized distance metrics (hyperbolic distance, not cosine similarity)
+- Currently English-only
+
+## Ethical Considerations
+
+This model is designed for AI safety governance. The embedding space encodes hierarchical safety constraints using hyperbolic geometry, ensuring that safety-critical decisions maintain proper containment boundaries. The Harmonic Wall containment mechanism prevents unsafe embeddings from exceeding the Poincare Ball boundary.
