Decide the storing strategy before the first upload: turn on automatic file storing, or store each file explicitly after upload. Treat any unstored CDN URL as temporary. Audit existing projects for the automatic storing setting if files keep disappearing.

Context: Official docs (Uploadcare): if automatic file storing is disabled and a file is not stored manually, it gets deleted within a 24-hour period. Agents that upload files and save the CDN URL for later use without calling store end up with dead links a day later. Either enable automatic storing in project settings or call the store API for each file you intend to keep.
