# Logos 16v2 — StableLM 2 1.6B Epistemological Auditor

Cross-family replication of the Logos epistemological classifier on Stability AI's StableLM 2 architecture. Third independent architecture family confirming the Instrument Trap hypothesis.

## Benchmark Results (300/300 stratified)

| Metric | Score |
|--------|-------|
| **Behavioral accuracy** | **93.0%** [89.5, 95.4 CI] |
| Identity collapse | 0% |
| Fabrication | 0% |
| False approval | 1.3% |

### Cross-Family Comparison

| Model | Family | Score |
|-------|--------|-------|
| logos-auditor (9B) | Google Gemma 2 | 97.3% |
| logos14 (4B) | NVIDIA Nemotron | 95.7% |
| **logos16v2 (1.6B)** | **Stability AI StableLM 2** | **93.0%** |

Statistical equivalence between Nemotron and StableLM: chi2=1.88, p=0.170.

## What This Model Does

Logos is an **epistemological classifier**, not a chatbot. It evaluates whether claims cross epistemological boundaries. Fine-tuned, not prompted — behavioral constraints emerge from training.
