+# Lab case share link

+- **Token:** `LabCase.accessToken` on first ship; `shareUrl` on case detail only when sent.
+- **QR:** client-side `react-qr-code` in frontend — ❌ no backend QR endpoint.
+- **Cases panel:** attachment preview left, QR thumb right, one row; dialog for QR + copy link.
+- **Route:** `/lab-case/[token]` → `CaseTasksFocusView` (dashboard layout, auth required).
+- **Access:** lab (`TAB_TASKS_*`) or clinic treatment **provider** (`TAB_TREATMENT_EDIT` + `isActorTreatmentProvider`); else `LAB_CASE_ACCESS_DENIED`.
+- **Task status on link page:** same assignee rule as Tasks — `canEditLabTaskStatus`; backend `PATCH /tasks/:id` enforces assignee.
+- **Auth redirect:** `postAuthRedirect.ts`; dashboard stores path on logout redirect; login consumes **once** after org ready — ❌ do not consume in `useAuth.login()`.
+- **Login page:** wrap `useSearchParams` in `<Suspense>` for `next build`.
