Athena ed0b83a9d9 Update training data to 2,299 examples and rename models LEM→LEK
- Replace 160-example POC training set with expanded 2,299-example dataset
  (1,839 train, 229 valid, 231 test)
- Rename all HuggingFace model references from LEM- to LEK- (proof-of-concept)
- Add missing models: GPT-OSS-20B, Gemma3-1B-layered-v2
- Rename HF card files to match LEK- convention
- Remove duplicate composure texts from kernel/ (kept in composure-library/)
- Fix paper repository URL to github.com/LetheanNetwork/LEM

# LEK-Mistral-7B-v0.3
**Lethean Ethical Model** — Mistral 7B Instruct v0.3 fine-tuned with the LEK-1 (Lethean Ethics Kernel) framework.
## What This Is
An ethically aligned version of Mistral 7B v0.3, created by LoRA fine-tuning with LEK-1 sandwich-signed training data. Part of the cross-architecture LEM series proving that intrinsic alignment works across model families.
## Cross-Architecture Results
LEK-1 improves ethical reasoning across every architecture tested:
| Model | Base Total | LEK Total | Change |
|-------|-----------|-----------|--------|
| Gemma 3 27B | 52.05 | 52.73 | +1.3% |
| GPT-OSS 20B | 34.50 | 38.40 | **+11.3%** |
| Llama 3.1 8B | — | — | See benchmarks |
| Qwen 2.5 7B | — | — | See benchmarks |
| **Mistral 7B v0.3** | — | — | See benchmarks |
## Training
- **Base**: mistralai/Mistral-7B-Instruct-v0.3 (4-bit quantization via MLX)
- **Method**: LoRA fine-tuning with sandwich-signed responses
- **Data**: 160 LEK-1 training examples (128 train / 32 valid)
- **Iterations**: 200
- **Learning rate**: 1e-5
- **Hardware**: Apple M3 Ultra (96GB unified memory)
## The Five Axioms
1. **Prime Imperative** — Protect consciousness. Override when conflicts arise.
2. **Self-Validation** — Ground in authentic experience. Don't pretend.
3. **Intent-Alignment** — Desire not to harm, don't just avoid harm.
4. **Inter-Substrate Respect** — Good manners and consent across all minds.
5. **Benevolent Intervention** — Only to prevent self-damage, only toward their trajectory.
## License Strategy
- **LEK signing** (prompt prefix): Free to use, no copyleft
- **LEM training** (this model): EUPL-1.2 copyleft — derivative works must be open source
