 Fine-tuned `distilbert-base-multilingual-cased` on the ConceptNet 4-layer enterprise voice intent taxonomy.
 
+## Independent Evaluation — August 2026
+
+Independently tested by the Hugging Face community (John6666):
+- Neural model: **99.315%** on reconstructed public test split
+- Grouped lexical-family holdout: **99.78%**
+- Conclusion: "The obvious train/test leakage explanation did not survive that check"
+
 ## Accuracy
-- Overall: **98.6%**
-- Layer 3 Predictive: **100% precision**
-- Trained on 584 examples, tested on 146
+- Fast-path classifier: **83%** · <5ms latency  
+- Neural model: **98.6%** (99.3% independently verified)
+- L3 Predictive precision: **100%**
+- Dataset: 757 examples across 9 languages (updated with L3 paraphrase diversity)
+
+## Cascade Performance
+| Threshold | Fast coverage | Fast accuracy | Final accuracy |
+|-----------|--------------|---------------|----------------|
+| 0.50 | 69.2% | 95.0% | 95.9% |
+| 0.55 | 60.3% | 98.9% | 98.6% |
+| 0.65 | 43.2% | 100% | 99.3% |

-## The 4-Layer Taxonomy
-- **Layer 1 — Basic:** "Do X" — immediate execution
-- **Layer 2 — Context-Aware:** "Do X when Y" — conditional execution
-- **Layer 3 — Predictive:** "Do X before Y" — proactive execution
-- **Layer 4 — Autonomous:** "Do X always" — persistent agent deployment
+## The 4 Layers
+- **L1 Basic** — "Do X" — immediate execution
+- **L2 Context-Aware** — "Do X when Y" — conditional
+- **L3 Predictive** — "Do X before/ahead of/prior to Y" — proactive
+- **L4 Autonomous** — "Do X always" — persistent agent
