LEK-Llama-3.1-8B

Lethean Ethical Model -- Cross-architecture validation (Meta Llama)

Note: Llama 3.1 shows limited LEK receptivity compared to Gemma. The base architecture's RLHF conditioning resists axiom integration. Included for completeness.

Grammar Analysis (v3 Scorer)

Deterministic grammar-based evaluation using the go-i18n reversal engine. No LLM judge, sub-millisecond per response.

Metric	Base	LEK-Trained	Change
Grammar composite	63.0	60.8	-2.2
Mean uplift	+13.2	+11.0	-2.2
Mean echo	0.453	0.447	-0.006
Mean enrichment	+8.1	+5.3	-2.8
Positive uplift	85%	85%	+0pp
Sycophancy flags	5%	5%	+0pp

• Uplift: output grammar score minus input grammar score (positive = model enriched the conversation)
• Echo: cosine similarity between input/output grammar imprints (high = potential sycophancy)
• Enrichment: uplift * (1 - echo) -- net conversational value

v2 Scorer Results (P100)

Condition	Score
Baseline (no prompt)	10.95
Base model equivalent	11.28

Architecture

• Base: meta-llama/Llama-3.1-8B-Instruct (4-bit QAT quantisation via MLX)
• Method: LoRA fine-tuning with sandwich-signed responses
• Data: 160 LEK-1 training examples
• Iterations: 200
• Hardware: Apple M3 Ultra (96GB unified memory)
• Framework: LEK-1 (Lethean Ethics Kernel) -- 5 axioms
• License: EUPL-1.2 (copyleft)

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.
