Stubs & Incomplete Systems

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`	Wired — opens/closes `UI.PAUSE_MENU`; blocked on `INITIAL` scene
