# Services:
#   Go: school-service, edu-search-service
#   Python: klausur-service, backend-lehrer, agent-core
#   Node.js: website, admin-lehrer, studio-v2
#
# Strategie:
# - Lint bei PRs
# - Tests laufen bei JEDEM Push/PR
# - Test-Ergebnisse werden an Dashboard gesendet
# - Builds/Scans laufen nur bei Tags oder manuell
# - Deployment nur manuell (Sicherheit)
