+```bash
+# Ejecutar todos los tests unitarios (no necesita Docker, Redis ni LLM)
+pip install pytest
+python3 -m pytest tests/ -v

+
+Los tests validan: compactación de contexto, extracción de key_data para historial, fingerprinting de tool calls, y cálculo de costes. Son 100% offline — no consumen tokens ni necesitan servicios externos.
