Uploading a PDF and calling a translation model looks like a two-step feature. In production, it is a job pipeline with untrusted input, two different extraction paths, several expensive stages, and an output that can be fluent while still being wrong.
That distinction matters for a small SaaS team. The translation request may come from support, sales, or an internal operations task. Nobody wants to operate a document platform, but the workflow still needs to answer basic questions:
Was the upload actually a PDF?
Does the file contain selectable text or scanned page images?
Can a retry create a second charge or a conflicting result?
