Separate observed facts, calculations, source requirements and professional interpretation.
Cloud Workspacenot configured
v38 cloud code is schema-ready but has not been connected to a live Supabase project in this build. Browser cases and the local Source File Vault remain the safe fallback.
Cloud Case Browsermulti-device retrieval
Cloud retrieval code requires the v39 migration plus a configured Supabase project. Without that, browser cases remain fully usable and no cloud state is fabricated.

Calculating…This hash fingerprints the recorded manual metadata, not the PDF bytes. A completed record documents the research path; it does not by itself prove field conformity.
Source File Vault0 source records
No source files recorded yet.
v37 stores exact source bytes in IndexedDB on this browser/device. Saved cases keep the SHA-256 reference. Clearing browser site data can remove these files, so this is not yet cloud archival storage.
