`GET /treatments/patients/:id/history` returns saved treatments for **that patient** scoped to the **logged-in clinician** (`Treatment.providerUserId` or linked `Appointment.providerUserId`). **Owners are not exempt** — each user only sees plans they created or own via their appointments.
`PastTreatmentsPanel` filters **already-fetched** history — no extra API params.
- **Not shipped to lab** — show treatments that have at least one lab-dependent detail (prosthesis via `labDependentCodes`) with `!sentAt`.
- **Date** — filter on `treatmentAt` matching that local calendar day.
- When **not shipped** is on and workspace is live (not browsing), prepend a synthetic **current draft** row (`id: 'current-draft'`) if it has pending lab-dependent details.
Saved lab-dependent detail with **no teeth** can autosave but **cannot** create a lab shipment.
- Inline banner in `TreatmentDetailsEditor` + `LabShipmentBlockedNotice` above dispatch when active detail qualifies (`isLabDependentDetailMissingTeeth`).
-`handleAddLabCase` shows toast with `labShipmentBlockedBody`.
- Dispatch panel only appears when a detail passes `isDetailReadyForLabDispatch` (persisted + lab-dependent + teeth).
## Lab case comments on details
Below each detail in the editor when the linked lab case is **in progress** (not all tasks completed):
-`canCommentOnDetailLabCase(detail)` — requires `sentAt`, `labCaseId`, and `!isLabCaseCompleted(taskProgress)`.
- Backend includes `tasks: { select: { id, status } }` on lab cases; `mapDetail` exposes `taskProgress: { completed, total }`.
## Appointments default selection
On today: in-progress slot first, else nearest start time to `now`. Other days: first appointment. Re-runs every 60s on today unless `selectionLocked`. Frontend filters appointments to `providerUserId === userId`.
**Today checkbox** (`ScheduleDayPicker`): unchecked when `selectedDay` is not today (e.g. after loading a historical treatment). Checking Today calls `onSelectDay(today)` which unlocks selection (`selectionLocked = false`) and resets browse/historical context; appointments reload and auto-select nearest to now.
## Lab org search (dispatch)
`LinkedOrganizationSearchCombobox` in `LabCasesDispatchPanel` — search-only results (no dropdown). No match + org tab access → **Invite a lab** navigates to `/organizations?action=invite-lab`. No org access → show permission message; dispatch stops.
Pattern mirrors `PatientSearchCombobox` in appointments.
## Scroll
Use `scrollWithinMainScrollContainer()` (not raw `scrollIntoView`) when jumping to lab dispatch panel — dashboard `<main>` is the scroll container; document scroll conflicts with `.app-web-bg { overflow: hidden }`.
Use shared `Checkbox` (not native `<input type="checkbox">`) to avoid focus-driven scroll jumps.
## Backend APIs
| Endpoint | Purpose |
|----------|---------|
| `GET /appointments?from&to` | Strip |
| `GET /treatments/patients/:patientId/history` | History (patient + org; filtered by provider) |
| `GET /treatments/appointments/:id/draft` | Load form on appointment select |
Filter in **backend**`listPatientHistory` / lab-case lists on patient + org + **provider scope** (`common/treatment-provider-scope.ts`). History is **per selected patient and per clinician**, not per day or all org plans.
