Backend & APIs/Uploads & mediaQuestion

What checks belong in a secure image-upload endpoint?

I am adding screenshots to community posts. The browser provides a MIME type, but I know that value can be forged. Current checks 4 MB maximum PNG, JPEG, WebP, or GIF Random generated filename What should happen before the file reaches object storage?

Backend & APIs/API designQuestion

How should I model an API result so every error case is exhaustively handled?

My current response type uses several optional properties, so impossible states compile. Code example I want the UI to require separate handling for success, validation failure, authentication failure, and an unexpected server error.
