Currently, NBT matching only works with exact matches. The NBT on the stack needs to be exactly the same as the NBT in the recipe. It'd be good to have a fuzzy mode, where the NBT on the stack may have more NBT, as long as it also has all the tags and values that the recipe requires.

didn't read but he's right

Matching is currently always fuzzy 🤔

Huh. I'll let yog know.
