Object Storage

Overview

This skill adds off-chain file/object storage with on-chain references. The MixinStorage mixin provides infrastructure for file operations; you track uploaded files in your own data structures using Storage.ExternalBlob.

Backend

File content is stored off-chain. The backend manages references to external files using the Storage.ExternalBlob type from mo:caffeineai-object-storage/Storage. The frontend handles the actual upload/download; the backend only stores the reference.

CRITICAL: ANY data field that represents a file, image, photo, document, or media MUST use Storage.ExternalBlob as its type -- NEVER Text. Using Text breaks the upload/download proxy. Method parameters that accept file uploads MUST also use Storage.ExternalBlob, not Text.

Correct:

blob : Storage.ExternalBlob
