# 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.
- **Important first:** `pinImportant=true` (sort pin, not filter).
- **Task assignment:** assign in Cases (`TAB_CASES_EDIT`); status edit on Tasks only for assignee or unassigned tasks; others see “Assigned to {name}”.
- **Grouped comments:** when `sortBy=date`, one comments icon on **case header** (not per row); flat sort keeps per-row comments.
- **Share link page** (`/lab-case/[token]`): reuses `TaskRow` + assignee rules; comments via token API — see `.cursor/skills/lab-case-share-link/SKILL.md`.
- **Case due dates:** clinic sets in Treatment lab dispatch; lab sees on Cases/Tasks; `overdue` filter + `sortBy=dueDate` on Tasks.
- **Mobile UX:** `LAB_TASK_STATUS_SELECT_CLASS` (44px tap target on small screens); `TaskCaseGroupHeader` sticky while scrolling grouped tasks; filter selects use same touch sizing on Tasks.
- **Show in case:** `GET /tasks/locate-page` finds page in full list; highlight + scroll.
- **Today deep links:** `parseTasksSearchParams` + `prosthesisTypeCode` / `unassignedOnly` / `overdueOnly` query params on Tasks.
