+- **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.
 - **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). Prosthesis type: stacked below `md`, 50/50 same-row from `md`. 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 **one row per tooth** (`LabCaseToothJobsList`) — types as colored catalog text. Content clinical field = **Notes** (not case comments).
 - **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.
 - **Lab dispatch attention:** `LabDispatchAttentionPanel` — unsent lab-dependent details; quick jump to dispatch.
 - **History API:** patient-scoped; non-owners filtered by provider on treatment or appointment; org owners see all.
 - **History filters (client-side):** `PastTreatmentsPanel` — “Not shipped to lab” + single date; helpers in `treatmentHistoryFilters.ts`.

 - **Edit gating:** `canEditTreatmentForDay` = permission + appointment + not past day + `live` mode. Sent detail locks that line; Add still OK same day. Upload rejects sent (`TREATMENT_DETAIL_SENT`).
-- **Lab search:** `LinkedOrganizationSearchCombobox`; invite lab via `/organizations?action=invite-lab` when permitted. New dispatch lines start empty (lab + apply-all / per-tooth prosthesis type).

One restoration slot per tooth (crown / indirect / screw-retained); implant abutments and post & core **stack**.

 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.
