+- GitHub remote: `pacificao/AgrarianGameBuild`
+- Current branch: `main`
+- Latest pushed game commit: `fdc919c Document world time persistence`
+
+Completed roadmap item:
+
+- `Save world time`
+  - Confirmed world saves persist `UAgrarianSaveGame::WorldHours`.

+  - Added `Scripts/verify_world_time_persistence.py`.
+
+Verification:
+
+- `python3 -m py_compile Scripts/verify_world_time_persistence.py` passed.
+- `python3 Scripts/verify_world_time_persistence.py` passed.
+- `git diff --check` passed.
+- No Windows editor compile was run for this item because it only documented
+  and verified an existing C++ persistence path.
+
+Deployment classification:
+
+- `Docs/email only` for this item.
+- Milestone still has `Server deploy required` pending because earlier 0.1.M
+  persistence runtime changes affect the multiplayer host.
