# Lab Tasks

- **Default sort:** newest `labCase.sentAt` first; `stepOrder` asc within prosthesis group (backend `buildOrderBy`).
- **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.
