"""Jarvis · Live Smoke-Test — Erster echter Durchlauf.

Dieses Skript testet den KOMPLETTEN Agent-Loop mit echtem Ollama.
Kein Mock, kein Fake — ein richtiger End-to-End-Test.

Voraussetzungen:
    - Ollama läuft (http://localhost:11434)
    - Mindestens ein Modell geladen (qwen3:8b reicht)
    - pip install -e ".[all]"

Nutzung:
    python scripts/live_smoke_test.py

# mark the module as skipped at import time when `__name__` is not

# function when executed directly (e.g. ``python scripts/live_smoke_test.py``)
