Anti_Pattern:
  Type: "Checkpoint sécurité en fin de pipeline"
  Symptômes:
    - Scans de sécurité exécutés uniquement après le build complet
    - Équipes de développement qui contournent les contrôles pour livrer plus vite
    - Vulnérabilités détectées tardivement après un investissement conséquent en développement

Pattern_Solution:
  Type: "Security Guardrails intégrés"
  Approche:
    - Mise en place de pre-commit hooks avec analyses rapides (linting, SAST léger)
    - Intégration de Policy-as-Code dans les templates CI/CD et manifests Kubernetes
    - Feedback sécuritaire en temps réel directement dans l’IDE des développeurs
