+# Modelfiles — System Prompt Evolution (V1–V42.6)
+
+86 files documenting the complete evolution of CyberRanger's identity-anchoring architecture.
+
+## What's Here
+
+- **32 Modelfiles** (`.Modelfile`) — Original Ollama Modelfile configurations (V5–V36)
+- **54 System Prompts** (`.txt`) — Extracted from Ollama model manifests covering every version from RangerBot V1 to CyberRanger V42.6
+
+## How to Read
+
+Each system prompt shows the exact instructions given to the model at that version. Compare versions side-by-side to see how the Ring 14.x architecture evolved:
+
+- **RangerBot V1–V9** — Early identity experiments (SmolLM2, Llama, Qwen bases)
+- **RangerBot V10–V22** — Bicameral mind, nervous system, integrated architecture
+- **CyberRanger V24–V33** — Ring 14.x formal structure, multilingual refusal
+- **CyberRanger V34–V42** — QLoRA integration, Mirror Architecture, Gold standard
+
