Crafting System Recipe Inventory Survival Kit

A server-authoritative crafting system: recipes consume materials from your session inventory and yield an output, and the SERVER checks and consumes them - a client can never craft without the materials. Drag 4 things and press Play - no code. Your inventory (seeded from Starting) and every recipe appear; a recipe's CRAFT button lights up only when you own the inputs. Crafted outputs go back into the inventory, so you craft in chains (Wood -> Plank -> Stick -> Axe). EDIT RECIPES with no code: each Folder in Recipes is named after its output, with a Yield Attribute and one IntValue per input (named after the material). Seed the inventory the same way under Starting - names are yours, map them to your own models. Grant materials from your own server code (unspoofable); clients only craft. SESSION: inventory resets on server close - a SAVE HOOK line shows where to persist. ONE server Script, ONE client LocalScript, no external services. For survival, tycoon and simulator games.
