Document upload
Upload a document — it is stored tenant-isolated, parsed into units and pre-filled into field drafts with source.
Every uploaded field is class 4 (self-report) until a human confirms it — at which point a glass-box claim is written with click-to-source back to the document unit (no auto-accept). Register facts arrive via Data & integrations and apply over self-report (class 2).
Demo · seed-data: Demo: no database/session connected here, so upload shows the honest "connect" path. In a connected environment (DATABASE_URL + signed in) it actually stores, parses and pre-fills — proven by the db tests.
