## Summary - Closes [#55](#55) (related [#46](#46)) - **Personal** Google Drive / OneDrive works for users **without** a company (personal RAG) - **Company** Drive still requires company + manager - Schema: nullable `DriveConnection.company`, personal `DocumentWorkspace.user`, ownership check constraints + conditional uniques - Runtime: `ensure_personal_workspace`, personal sync → personal WS, chat/document APIs fall back to personal WS when `company_id` is null - Supersedes the interim "reject with `no_company`" approach (wrong for personal connect) ## Test plan - [x] OAuth: personal Drive callback with `user.company=NULL` succeeds (`company_id=NULL` on connection) - [x] OAuth: company Drive still returns `no_company` / `forbidden` appropriately - [x] Chat tenant scope creates personal workspace for solo users - [x] Drive sync + document view suites (`91` related tests) - [ ] Manual: solo entitled user connects Google Drive → success, sync lands in personal workspace - [ ] Manual: company manager company Drive still works - [ ] Migrate prod/staging with `0029_personal_drive_rag_without_company`Reviewed-on: #56
