# Compte de PROVISIONNEMENT : crée buckets, politiques et comptes de service —
# aucun droit sur les objets. C'est lui que lisent les rôles CI des apps, pour
# qu'elles déclarent leurs buckets sans qu'on leur confie le root.
# Décisions : factory/doc/adr/20260726-stockage-objet-minio.md

# ⚠ Noms d'actions issus de la documentation MinIO, NON éprouvés contre le
# serveur : le premier apply les confirmera ou les corrigera.
