+
+These exist in the codebase but have no real implementation yet. Don't assume they work.
+
+| File / Symbol | Status |
+|---|---|
+| `Save.gd` | No actual serialization — all persistence is a stub |
+| `Quest.gd` | Empty singleton |
+| `CutsceneSingleton.gd` | Minimal stub |
+| `BattleFighter.getAIDecision()` | Always returns `null` |
+| `BattleDecision.execute()` | Stub |
+| `BattleItem.perform()` | Stub |
+| `CookingScene.tscn` | Placeholder UI only |
+| Response branching in `DialogueAction` | Auto-selects first allowed response; no response UI exists yet |
+| `Pause.gd` | Logic commented out |
