+
+- `/mnt/projects/AgrarianGameBulid`
+- GitHub remote: `pacificao/AgrarianGameBuild`
+- Current branch: `main`

+Completed roadmap item:
+
+- `Add corpse/backpack placeholder if needed`
+  - Decision: no physical corpse/backpack actor is needed for the 0.1.J MVP
+    respawn loop because death inventory loss is not active yet.
+  - Reserved future corpse/backpack recovery as a persistent, server-owned,
+    interaction-gated death-recovery record once inventory loss and decay rules
+    exist.
+  - Updated persistence and multiplayer networking design docs with the
+    decision.
+  - Added `Scripts/verify_corpse_backpack_decision.py`.
+
