+* **Extend**: Plot each user's latest approximate location on an accessible, server-rendered Natural Earth world map in the operations dashboard.
 * **Refine**: Make group assignment exclusive with default fallback, add group deletion, automatically synchronize Discord nicknames with status notices, expose filterable event details, add an SSR operations dashboard, and improve accessibility.
 * **Extend**: Add SoMC Portal branding, live Discord identity details, admin guild configuration visibility, and fail-closed group-based Minecraft admission.
 * **Refine**: Group repeated access networks, confirm linked Discord nickname changes before mutation, and add DMG Games sponsorship attribution.

 # Acceptance Criteria
 
 - [x] The administrator landing page is a dashboard rather than a settings form.
+- [x] An open-data world map plots each user's latest observation with valid approximate coordinates.
+- [x] Map markers link to user records and have an accessible text-table equivalent.
+- [x] Natural Earth boundaries are bundled and server-rendered without disclosing map or location requests to a third party.
 - [x] The dashboard graphs new registered users by UTC day for the previous 14 days.
 - [x] Monthly active users count distinct users observed through portal or game activity in the previous 30 days.
 - [x] Monthly active Minecraft accounts count distinct linked accounts observed in the previous 30 days.

 # Validation
 
 - Missing-day chart behavior is covered by [`apps/web/src/lib/admin-metrics.test.ts`](../apps/web/src/lib/admin-metrics.test.ts).
+- Coordinate parsing, projection, linked markers, text fallback, and attribution are covered by the user-world-map tests.
 - The Next.js production build reports the dashboard and database-backed console pages as dynamic server-rendered routes.
