 **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.
 - **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 case comments** on a detail when sent and lab case tasks are not all `COMPLETED` (`taskProgress` from API).
+- **Lab shipments rail**: unified list with scope toggle **This patient** vs **All updates** (unread across org, includes patient name).
+- **Unread semantics**: Treatment tab badge = count of unread cases (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.
 
 **Lab Tasks tab:** Newest case first; steps ordered 1→N; case grouping when sorted by date; `stepCompleted` filter; prosthesis colors from `PROSTHESIS_TYPE_COLORS` via 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`.
