- GravityFlipListSubCommand: iterate registry.all(), format 'name : (min) -> (max) [state]'
- GravityFlipDeleteSubCommand: registry.remove + save, clear error on unknown name
- GravityFlipToggleSubCommand: read current enabled, flip via setEnabled, save, report new state
- All three extend CommandBase (works from server console, not just player)
- Save-failure path: keep in-memory change, truthful message (mirror define pattern)
