Post a simple wheel with names and core duties that rotate every week, plus anchored roles like plants or pets that prefer continuity. Spin on Sundays, swap respectfully for big events, and note exceptions. The predictability reduces bargaining, while anchors prevent fragile routines from resetting constantly.
Give chores point values, then run a weekly snake draft where highest points must be cleared. People pick according to schedules or preferences, trading when emergencies arise. Over cycles, everyone handles tough items, yet autonomy remains high, making buy-in stronger than strict assignment from a single planner.
