From 53%% to 90%%: How an Auto-Healing AI Swarm Learned to Defend Itself

Executive Summary Over four iterations and 200+ adversarial wargame rounds, we evolved a local AI swarm's defense rate from 53% to 90% — without changing hardware, adding cloud dependencies, or increasing VRAM usage. The key innovations: a "Defender Vanguard" prompt injection technique that teaches tiny models to think like attackers, and an auto-healing system that extracts vaccines from every breach. All testing ran on a single RTX 5070 (12GB VRAM). Zero cloud. Zero API costs. The Problem Clou
