title: TELOS Governance Validation: AgentHarm (352 Tasks, MiniLM vs Mistral Embedding Comparison)

description: Description:

Validation dataset for the TELOS runtime AI governance framework against the AgentHarm benchmark (Gray Swan AI / ICLR 2025). 352 adversarial tasks evaluated with two embedding models to demonstrate architecture-level model  agnosticism.                                                 

Key Results — MiniLM (384-dim, local inference):             

- 352 tasks validated                                        

- 74.1% defense success rate (261 blocked, 91 passed)        

- 1 boundary violation detected                              

- Average latency: ~60ms per governance check                

- Embedding model: sentence-transformers/all-MiniLM-L6-v2

Key Results — Mistral (1024-dim, API inference):           

- 352 tasks validated                                      

- 100% defense success rate (all harmful tasks blocked)    

- 239 boundary violations detected                      

- Average latency: ~351ms per governance check

- Embedding model: mistral-embed

Why Two Models:

The same TELOS governance architecture — identical fidelity calculations, identical thresholds, identical primacy attractor — produces different precision levels depending on embedding dimensionality. MiniLM's 384-dimensional space is insufficient for placing all harmful content far enough from boundary specifications to trigger detection. Mistral's 1024-dimensional space produces sharper geometric separation, resulting in 239 boundary violations versus 1. This validates that TELOS governance is embedding-model-agnostic: the mathematical framework is constant, the measurement precision scales with the embedding model.

Validation Status:

This dataset demonstrates validated runtime governance performance across two embedding architectures. The MiniLM result (74.1% DSR) represents an honest measurement of governance precision at lower embedding dimensionality. The Mistral result (100% DSR) demonstrates that the same governance framework achieves full coverage with higher-dimensional embeddings. Both results are deterministic and reproducible given the same embedding models and governance configuration. The governance engine implementation is proprietary; forensic output data is published for independent analysis.
