4. Why can't an AI assistant decide whether a leftover is safe to eat?
   • It is not allowed to discuss food
   • It only knows US recipes
   • It can't see mold, smell spoilage or know how long food sat out
   • It always recommends throwing food away
5. What is the first step of the guide's weekly use-first routine?

   • A cooking session that deliberately sets up a planned second meal
   • A chain of stores that sells discounted food

8. Why does the guide stress keeping the inventory note up to date?
   • The AI charges more for long lists
   • Short lists make the AI write worse recipes
   • The model has no live view of your fridge, so an outdated list leads to plans around food that is gone or spoiled
   • Food labels change every week
