+- **Grouping:** only when `sortBy=date`; flat list + hint for other sorts.
+- **Prosthesis colors:** `PROSTHESIS_TYPE_COLORS` + `prosthesisTypeBadgeStyleFromCatalog` — never row index.
+- **Step completed filter:** `stepCompleted` query param; groups where that step is `COMPLETED`; with `IN_PROGRESS` status shows remaining open tasks only.

+
+# Lab Tasks
+
+Main UI: [`frontend/src/components/ui/lab/TasksPage.tsx`](frontend/src/components/ui/lab/TasksPage.tsx)  
+Backend: [`backend/src/modules/tasks/`](backend/src/modules/tasks/)
+
+## Default sort (backend)
+
+`sortBy=date` + `sortDir=desc`:
+
+1. `labCase.sentAt` desc (newest case first)
+2. `labCaseId`, `treatmentDetailId`, `prosthesisTypeCode` asc (stable grouping)
+3. `stepOrder` asc (steps 1→N within prosthesis group)
+4. `id` asc
+
+Other sorts use flat list on the frontend; `stepOrder asc` is still a tiebreaker.
+
+## Case grouping (frontend)
+
+- **`sortBy === 'date'`** → grouped view via [`taskListGrouping.ts`](frontend/src/components/lab/taskListGrouping.ts): case header → prosthesis sub-header → task rows.
+- **Other sorts** → flat list; show muted hint (`groupingOff*` i18n keys). Each row keeps clinic/patient/teeth context.
+
+Components: `TaskCaseGroupHeader`, `TaskProsthesisGroupHeader`, `TaskRow`.
+
+## Prosthesis colors
+
+- Map: [`catalog-type-colors.ts`](frontend/src/components/shared/catalog-type-colors.ts) → `PROSTHESIS_TYPE_COLORS` (one hex per catalog code).
+- Resolve with [`prosthesisTypeDisplay.ts`](frontend/src/components/treatment/prosthesisTypeDisplay.ts) — use `prosthesisTypeBadgeStyleFromCatalog(code, catalog)`, **not** list row index.
+- Load catalog via `prosthesisCatalogApi.list()` on Tasks/Cases/Today dashboard.
+
+## Filters
+
+| Param | API | UI |
+|-------|-----|-----|
+| `q`, `clinicOrganizationId`, `status` | `GET /tasks` | Search, clinic, status |
+| `stepCompleted` | `GET /tasks` | Workflow step dropdown |
+| Clinics + steps options | `GET /tasks/filter-options` | Populates dropdowns (not from current page) |
+
+**Step completed filter:** Restricts to prosthesis groups `(labCaseId, treatmentDetailId, prosthesisTypeCode)` where that `workflowStepCode` task is `COMPLETED`. Combined with `status=IN_PROGRESS`, returns only in-progress tasks in those groups (completed step row hidden).
+
+## APIs
+
+- `GET /tasks` — paginated flat task list (grouping is client-side when `sortBy=date`)
+- `PATCH /tasks/:taskId` — update status
+- `GET /tasks/filter-options` — clinics + workflow steps (localized)
+
+List items include `caseSentAt` for case headers.
+
+## Permissions
+
+`TAB_TASKS_READ` / `TAB_TASKS_EDIT`; `LabOrgGuard` on all task routes.
