The wall-framing takeoff laid out stairs down to the notch geometry, the tread boards and the guard posts, but its output never mentioned how a stringer gets fastened at either end. A framer reading the order would find lumber and no hanger.
It now adds a hardware block: one top connector (a hanger or a bolted ledger connection) and one foot anchor for every stringer. Hand check: a 36 in wide stair at 16 in spacing needs ceil(34.5 / 16) + 1 = 4 stringers, so 4 and 4; a 60 in stair needs ceil(58.5 / 16) + 1 = 5.
This is a count, not a design. Connector size, fasteners and the load path are the engineer's or the manufacturer's call, and the output says so. Nothing here was checked against a permitted stair plan; a real one is still wanted.
