The short answer
In the hosted public beta, Google Drive and Docs need a connection; they are not live on day one. Files and Obsidian are the live first source. After Drive is connected, Pantasso reads approved folders, file metadata, document content, and owner context available through the connected Google account. It turns that material into cited company context without assuming access to the rest of Drive. Workspace owners choose the folder or file boundary and verify supported content during setup.
