> As soon as it turns into score keeping, the relationship will almost certainly go sideways.

The system / cards is not about keeping score: each card is a task, and whomever holds the card is responsible for it from start to finish. E.g., three of the cards are "Meals (Weekday Breakfast)", "Meals (Kids; School Lunch)", and "Meals (Weekday Dinner)"; this may fall to one person, but there is also the "Groceries" card:

> Your family needs to eat. Can we all agree on that? Good. So how do the pantry and refrigerator get stocked on an ongoing basis? With CPE. This includes noticing what’s about to be used up or expire, keeping a running grocery list, and getting to the market . . . ideally before you realize there’s not a drop of milk in the fridge. Even if your family orders groceries online and your go-to dinner is frozen pizza, this card requires CPE nearly 365 days a year. Consult the various “Meals” cardholders regularly so you can be sure you have taco shells in the cupboard for taco night.

So the Meals person(s) have to plan the meal(s), and make an ingredient list for those specifically, and add to to a grocery list, but grocery buyer needs to take stock of what is already present in the fridge/freezer/pantry and buy anything missing generally, and specifically for the meals planned.
