 **Treatment tab:** Preview and editable form are **separate** until the user clicks **Load into workspace** on a history item. See `.cursor/skills/treatment-workspace/SKILL.md` before changing that flow.
 
+**Treatment edit / details (quick ref):**
+- Day/mode gate: editable only for live draft on today/future (`canEditTreatmentForDay`). Past day / historical load → read-only form.
+- Sent-to-lab detail locks that line; **Add detail** still OK same day; **Remove detail** = trash icon on each detail chip (not in the wizard Content step) — only unsent and not the last line. Attachment upload blocked when sent (`TREATMENT_DETAIL_SENT`).
+- **Entry wizard:** `WizardStepper` — Teeth → Content → Lab; Lab step only when active detail type is lab-dependent (prosthesis). Detail chips ≠ wizard chrome (chips stay bordered tabs; stepper is numbered rail).
+- **Tooth selection:** Shift+click same-arch range = connected group; plain click on a connected tooth collapses the whole span to that single tooth (no peel). Helpers: `toothSelectionGroups.ts`. Connected label: `ConnectedSelectionBadge` (shared `Badge` + primary tint).
+
 **Treatment lab rules (quick ref):**
 - Lab-dependent details (e.g. prosthesis) **without teeth** can save but **cannot ship** — show `LabShipmentBlockedNotice` + inline banner; toast on dispatch add.
+- Detail treatment type need **not** match appointment purpose — purpose only pre-fills new details.
 - **History filters** are client-side only (`treatmentHistoryFilters.ts`): “Not shipped to lab” + single date on already-fetched patient history; includes live current draft when filtering.
 - **Lab shipments rail**: unified list with scope toggle **This patient** vs **All updates** (unread across org for **this clinician's cases only**, includes patient name).
 - **Unread semantics**: Treatment tab badge = count of unread cases **for the user's own treatment plans** (per-case read cursor) and clears when a case is opened/marked read (not on tab visit).
 - **Lab shipment progress + comments**: shown in **Lab dispatch panel** for the active shipment; expanding activity / opening comments marks that case read.
 
+**Appointments (quick ref):** Do not delete (or change patient) when `hasTreatment`; codes `APPOINTMENT_HAS_TREATMENT` / `APPOINTMENT_PATIENT_LOCKED`. Appointment delete does not cascade-delete treatments. See `.cursor/rules/appointments.mdc`.
+
 **Lab Tasks tab:** Newest case first; steps ordered 1→N; case grouping when sorted by date; `stepCompleted` filter; prosthesis colors from catalog; task assignment in **Cases** (compact row: status + assignee + last update); on **Tasks**, all staff see every task but only assignee (or unassigned pool) can change status — others see “Assigned to {name}” instead of the status dropdown; **case due dates** set/edited in clinic Treatment lab dispatch, shown on lab Cases/Tasks with overdue filter + sort; **mobile:** larger task status controls, sticky case header when grouped; **tab badges:** `LabCaseActivity` + `GET /notifications/tab-counts` (lab Cases/Tasks split, clinic Treatment) — see `.cursor/skills/lab-tasks/SKILL.md` and `.cursor/skills/lab-notifications/SKILL.md`.
 
 **Lab Cases tab:** Filter by **prosthesis type** (not treatment type); auto-select newest case on open; list cards use `LabCaseProsthesisGroupsList` (colored type + teeth, shared with Treatment rail). Deep link: `?caseId=`, `?clinicOrganizationId=`. **Share link:** QR + URL on sent cases (attachment left, QR right); opens `/lab-case/[token]` focus page.
