Supports persistence, retrieval and removal of file resource references, up to 500 per session. Files must be live and owned by the current tenant. Paths default to /mnt/session/uploads/<file_id>; custom paths are rooted there and parent traversal is rejected. File content is immutable through this API. Sandbox synchronization is not implemented in this batch.
