May 2025 monthly summary for suitenumerique/drive: Delivered automated S3 bucket CORS configuration management via a Django management command set_bucket_cors. The command derives allowed origins from Django's ALLOWED_HOSTS, applies standard CORS rules for common HTTP methods, supports retrieval of existing configuration, and gracefully handles cases where no configuration exists. This reduces manual ops, improves consistency, and reinforces secure cross-origin access for asset hosting.
