# Brief: Focused integration test for CrowdSec startup in Charon container
# This test verifies that CrowdSec can start successfully without the fatal
# "no datasource enabled" error, which indicates a missing or empty acquis.yaml.
#
# Steps:
# 1. Build charon:local image if not present
# 2. Start container with CERBERUS_SECURITY_CROWDSEC_MODE=local
# 3. Wait for initialization (30 seconds)
# 4. Check for fatal errors
# 5. Check LAPI health
# 6. Check acquisition config
# 7. Check installed parsers/scenarios
# 8. Output clear PASS/FAIL results
# 9. Clean up container

# Ensure we operate from repo root
