+- **Split counts (Option B):** Lab Cases = sent + clinic comments + important; Lab Tasks = completions + lab comments + assignments (assignee-only); Clinic Treatment = visible lab comments + completions.
 - **API:** `GET /notifications/tab-counts`; **Cases + Treatment** use per-case read + `hasUnread` on list cards; Tasks marks read on tab visit. Treatment rail uses `TreatmentLabCasesPanel` + `LabCaseTrackerCard` + activity feed.
 - **Pattern:** `useTabBadgeCounts` + `notifyTabBadgesChanged()` — same shape as `usePendingConnectionsCount`.
 - **Live:** inbox Socket.IO `notification.created` → `notifyTabBadgesChanged()` (and org pending event when relevant). **Mounted** Cases/Tasks/Treatment/Orgs pages soft-refetch lists; unmounted tabs do not. Sidebar badge counts always refetch (hook is always mounted).

 **Inbox card context** is denormalized inside `UserNotificationService.notify()` (`enrichInboxPayload`) from ids already on the payload (`labCaseId`, `taskId`, `fromOrganizationId`). Emit sites stay thin (`{ labCaseId }`, etc.). Inbox list/read does **not** join related tables. Older rows may lack these fields until new events are emitted.
