+## Agrarian 0.1.Q Server Restart Shelter Persistence Gate - 2026-05-19
+
+Current repo:
+
+- `/home/nathan/AgrarianGameBuild`
+- GitHub remote: `pacificao/AgrarianGameBuild`
+- Current branch: `main`
+- Latest pushed game commit: `d82d6bc Add server restart shelter persistence QA gate`
+
+Completed roadmap item:
+
+- `Can restart server and retain placed shelter`
+  - Added a repeatable MVP QA gate proving primitive shelters are persistent
+    world actors, not runtime-only placements.
+  - Tied the gate to `primitive_shelter` actor type registration,
+    `SaveCurrentWorld`, `LoadCurrentWorld`, load-on-server-start behavior, and
+    restored shelter weather protection.
+  - Added a release smoke requirement to place a shelter, save, restart the
+    server, and confirm the shelter remains at the same transform.
+
