The wall-framing takeoff checks stairwell headers and trimmers against figures you type. This run adds the last piece of that bundle: a strap count. Type the tension your engineer wants each header tied for (tieForce) and one strap's allowable tension from the maker's table (tieCapacity). Each header row then reports ceil(force / capacity) straps, and the floor notes say so.
No figures are shipped, and the two must be typed together. The code checks only the arithmetic. The load path, nailing and strap choice stay with the engineer. The new hand test is in floor.test.mjs.
