Rene Fichtmueller a3793a1357 feat: ShieldX v0.1.0 — Self-Evolving LLM Prompt Injection Defense
10-layer defense pipeline with kill chain mapping, self-healing,
self-learning, and compliance reporting. Local-first, zero cloud deps.

- 72 detection rules across 7 kill chain phases
- 294 unit tests, 500+ attack corpus samples
- Management dashboard (Next.js 15, 10 pages)
- Automated resistance testing (2x daily, 31 probes)
- MITRE ATLAS, OWASP LLM Top 10, EU AI Act compliance
- Integrations: Next.js middleware, Ollama, n8n
- PostgreSQL 17 + pgvector for persistent learning
