"answer": "Once each epoch, a random handful of identities receives a physical letter, like a comet: unannounced and impossible to schedule around. The letter carries a one-time code, due within 3 days, proving a real, distinct postal address. The registry rejects duplicates, PO boxes, and bulk drops; a failed check freezes the identity until re-verified. A farm faking 10,000 identities needs 10,000 real addresses at about $30 a month each in rent and handling, $300,000 every month. Solid-looking karst collapses under weight; a cedar post at a real door does not move.",
