+

+
+- `/home/nathan/AgrarianGameBuild`
+- GitHub remote: `pacificao/AgrarianGameBuild`
+- Current branch: `main`
+- Latest pushed game commit: `4370924 Add full day night survival QA gate`
+
+Completed roadmap item:
+
+- `Can survive one full day/night cycle`
+  - Added a repeatable MVP QA gate for surviving one compressed Agrarian day.
+  - Anchored the pass condition to `4 real hours = 1 in-game day`, replicated
+    world time/solar phase, authoritative hunger/thirst/stamina/body
+    temperature/health pressure, fire and shelter mitigation, critical survival
+    HUD visibility, and save/load persistence coverage.
+  - Refreshed the stat save/load verifier to match the current
+    `RestoreSavedItems` inventory restore path.
