- **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. No stepper unless prosthesis — then `WizardStepper` Treatment → Lab with Back/Next. Chip switches reset to the treatment form unless `pendingEntryStepRef` requests Lab (shipments rail open). 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 once typed (sync live draft onto the open card); untyped keep 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 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). Empty details persist as `[]`. New treatment seeds one blank detail; load of empty stays `[]`. No delete in type/notes fields.
- **Lab shipment block:** lab-dependent detail with no teeth saves but cannot ship — same inline amber banner on Treatment and Lab (`labBlockedBannerClass`); toast on add shipment. Empty plan (`[]`) still shows type-first overlay (not a blank Add-only card).
- **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`).
