 # 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.
+- **Grouping:** only when `sortBy=date`; flat list + hint for other sorts. Unconnected teeth stay one pipeline; **connected** teeth that share a type share a pipeline; `partial_denture` is one pipeline for all selected teeth.
+- **Prosthesis colors:** `PROSTHESIS_TYPE_COLORS` + `prosthesisTypeColorFromCatalog` as text (no type pills) — never row index. Stacked `code+code` labels use `ProsthesisStackedTypeLabel` (one color per type).
 - **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.

 - **Current draft** preview: omitted in live editing (form is the source). History browse still uses preview + **Load into workspace**.
-- **Entry:** Type dropdown + `TreatmentDetailAttachmentsStrip` on one row, bordered chart (Cases chrome), then full-width auto-growing Notes. Prosthesis types live on the chart (including Upper/Lower arch). Lab dispatch is always under chart+notes when the active type is lab-dependent — no Treatment→Lab stepper. Lab-rail / Go to dispatch scrolls to the panel (`pendingScrollToLabRef`). Lab-dependent chips use colored sent/unsent text; sent date is on Lab dispatch. Lab dispatch keeps comments.
+- **Entry:** Type dropdown + `TreatmentDetailAttachmentsStrip` on one row, bordered chart (Cases chrome), then full-width auto-growing Notes. Prosthesis types live on the chart (teeth, or Upper/Lower arch for jaw products). Screw-retained stacks with a crown; partial denture is selected on FDI teeth.

Lab-dependent chips use colored sent/unsent text; sent date is on Lab dispatch. Lab dispatch keeps comments.
 - **Tooth hits:** unrotated full cell, `pointerdown` only (not `click` too — double-toggles). Glyph `pointer-events-none`; nest scale/hover inside the rotate wrapper. Groups: `toothSelectionGroups.ts` (never 1-tooth connected); prune lab `toothProsthesis` on change.
 - **Day strip:** `ScheduleDayPicker` `compact` centered in the header. Timed cards use purpose banners. Unscheduled cards use the same banner from the **first detail’s type only** (live draft for the open card); empty first line keeps chip theming. Trash inherits banner ink. Strip-delete only when `areUnscheduledDetailsStripDeletable` (blank lines or `[]`); persist `[]` then `DELETE /treatments/:id`.
-- **Lab dispatch UI:** due date end-aligned beside title (`sm:flex-row` + `justify-between`; stacks on mobile). Job list is **one row per tooth** (`LabCaseToothJobsList`) — types as colored catalog text. Content clinical field = **Notes** (not case comments).
+- **Lab dispatch UI:** due date end-aligned beside title (`sm:flex-row` + `justify-between`; stacks on mobile). Job list is `LabCaseToothJobsList`: connected same-type teeth share a row; unconnected teeth stay one row (stacked types as colored catalog text).

 - **Lab comments:** shared `LabCaseCommentsPanel` (newest-first; sent=`justify-start`, received=`justify-end`; `viewerSide`) across Treatment / Cases / Tasks / share. Use logical `text-start`/`text-end`, not left/right.
 - **Detail chrome:** chips (type + teeth) + Add at top; **Remove** = trash on chip (unsent, including last line; disabled when day-locked / no edit / uploading). Last-line confirm: plan will be empty until Add. Empty `[]` shows `noDetails` (not the type-first overlay). New treatment seeds one blank detail. No delete in type/notes fields.
 - **Patient search:** `PatientSearchCombobox` in the **page header** (workspace-wide). Opens today’s strip visit if any, else latest history. No visit/history → inline editor empty state pointing to **New treatment** in the rail (never a dialog, never auto-create). **New treatment** stays at the top of the left rail; selected-patient card sits under it. Picker: Walk-in first, then a matching full-width card for the current named patient (name + mobile/email, else hint), then search. Never auto-create from the appointment card.
