+## Agrarian 0.1.F Resource Respawn Rules - 2026-05-17
+
+Current repo:
+
+- `/mnt/projects/AgrarianGameBulid`
+- GitHub remote: `pacificao/AgrarianGameBuild`
+- Current branch: `main`
+- Latest pushed game commit: `a5ec210 Add MVP resource respawn rules`
+
+Completed roadmap item:
+
+- `Add respawn rules for MVP`
+  - Added native resource-node respawn fields:
+    `bRespawnsForMvp`, `RespawnDelaySeconds`, and `MaxHarvests`.
+  - Added server-side respawn timer logic. Renewable nodes schedule a timer
+    only when fully depleted.
+  - Respawn restores replicated `RemainingHarvests` and re-enables
+    visibility/collision.
+  - Configured MVP Blueprint defaults:
+    - wood respawns after `900` seconds;
+    - fiber respawns after `600` seconds;
+    - edible plants respawn after `1200` seconds;
+    - stone remains nonrespawning.
+  - Regenerated and saved resource Blueprints with the respawn defaults.
+  - Added `Scripts/verify_resource_respawn_rules.py`.
+  - Updated the roadmap, technical design document, Ground Zero resource pass,
+    `setup_playable_blueprints.py`, and `verify_playable_blueprints.py`.
