-- Prosthesis uses `WizardStepper` (Treatment → Lab) with Back/Next. Lab dispatch keeps comments.
+- Prosthesis types are assigned on the chart (`ProsthesisAssignChart` + `ProsthesisJobPopover` in `prosthesisTree.ts`). One restoration slot per tooth (crown / indirect / screw-retained); implant abutments and post & core **stack**. Arch products (denture, night guard, digital) use **Upper arch / Lower arch** labels and store `UA`/`LA` rows — they do not select 16 FDI teeth. Lab dispatch is on the same screen (no Treatment → Lab stepper).
 - Detail chips show **type + teeth**, not “Detail N”. Lab-dependent chips use colored sent/unsent text (same size as the label); sent date stays on Lab dispatch.
 - Detail type may differ from appointment purpose. Purpose seeds the first line of an empty **appointment** draft (first open, and **Add detail** when the plan is `[]`). Later **Add detail** starts with an empty type. Unscheduled / New treatment still seeds a blank first line.
-- Switching `activeDetailId` resets to the treatment form, unless `pendingEntryStepRef` is set to `lab` first (lab shipments rail / “Go to dispatch” / load-with-focus).
+- Lab shipments rail / “Go to dispatch” / load-with-focus **scrolls** to the dispatch panel (`pendingScrollToLabRef` + `labPanelRef`).
 - Live draft is **not** duplicated in the left rail preview; preview is for history browse only.

+Helpers: `frontend/src/components/treatment/toothSelectionGroups.ts`. Persisted as `toothSelectionGroups` on the detail. Lab **dispatch** lists **one row per tooth** (`LabCaseToothJobsList`, colored catalog types). After send, Cases/Tasks keep one item per tooth; stacked types on that tooth **union** their workflow steps (not merge teeth by type). `LabCaseTask` unique key includes `tooth`.
 
 Chart hit-testing (`FdiToothChart.tsx`): the hit target is the **unrotated full cell** (`pointerdown` + keyboard). Do **not** bind both `pointerdown` and `click` (double-toggle looks like a miss). Visual glyph is `pointer-events-none`; tilt lives on the outer wrapper; **scale/hover is nested inside** so inline `transform` does not kill scale. Horizontal inset (~22%) leaves a dead zone between teeth; FDI numbers are also clickable (`ToothNumber`).
 
 - **Plain click:** add/remove single; deselecting a tooth in a bridge removes it and splits/shrinks remaining sides (never a 1-tooth connected group).
 - **Neighbor circles:** when two arch-adjacent teeth are both selected, an empty circle appears **between** them (not per-tooth). Click empty → connect; click filled → disconnect (teeth stay selected). Transitive A–B + B–C = one bridge.
 - **Shift+click:** inclusive same-arch range → all selected as **singles** (empty circles); overlapping existing bridges are absorbed as singles too. Midline neighbors (11–21, 41–31) allowed.
+- **Prosthesis assign chart:** Shift = range then assign to the span; Ctrl/Cmd or drag copies the last type-set. Arch products open from the Upper/Lower arch labels and store `UA`/`LA` (not 16 FDI teeth). `pruneToothProsthesisForGroups` must keep those sentinels.
 - Prevent browser selection artifacts (`select-none`, Shift `preventDefault` on mousedown).
 - On group change, prune/remap `labCase.toothProsthesis` via `pruneToothProsthesisForGroups`.
 - Connected UI label: `ConnectedSelectionBadge` (shared `Badge` + primary tint) in dispatch + lab case lists.
