  "summary": "The brief discusses best practices for Node.js capacity planning when generating AI images and storing them in private object storage. The key recommendations include keeping generated images in private storage, using the object key instead of a public URL in application state, and minting short-lived presigned download URLs after application authorization. It is emphasized that the deciding factor is not the upload syntax, but whether the delivery path can handle retries, bursts, and expired links without turning the application server into an image proxy. The article also advises verifying identity and lifetime before issuing a presigned download URL, focusing on identity and lifetime rather than CORS, and storing an ownership record that binds the application principal to an opaque object key. The database is presented as the authorization ledger, while object storage holds the actual image bytes. The importance of a key layout designed for distribution, avoiding sensitive metadata in the key, and configuring narrow CORS policies for browser JavaScript access is highlighted. Short-lived links are recommended to reduce exposure window, but the specific lifetime depends on various factors such as client retries, render size, user geography, and service level objectives (SLO). The brief concludes by suggesting measuring the time from URL issuance to completed transfer to determine an appropriate lifetime.",
