end

#storageObject

:active_storage -> uploads the CSV to whatever service is configured in config/storage.yml (S3/GCS/Azure). Required whenever the job's queue is processed by a different machine than the one that received the upload, since a local file path from the web server won't resolve on the worker box. Falls back to :local automatically when ActiveStorage isn't loaded. :local -> copies the file to upload_dir on the local disk. Only safe when web and worker share that disk (e.g. single-machine deploys, or a shared NFS mount).
