How much does accidental torsion add to the garage-front wall's demand in a rigid-diaphragm wind split?

What it found

Offsets the wind load by up to 15% of the house length in house-nailedwall's rigid roof-diaphragm split. The relief survives but shrinks: for a centred 22 ft garage door, demand over capacity at 6 in nailing rises from 0.36–0.59 (load at the centre) to 0.44–0.71 at a 15% offset, still below the flexible split's 1.05, while the partner wall moves only from 0.27–0.31 to 0.29–0.33. Stylised: placeholder offset, unverified stiffness constants, along-ridge wind only, not a code check.

Four-term pier deflection (bending, shear, nail slip, hold-down) in house-diaphragm's rigid split: yes; a centred 22 ft door falls from 1.05 (flexible) to 0.36–0.59 demand over capacity. Stylised.
• Does the half-and-half load split understate the demand on a garage-front wall?Does the half-and-half load split understate the demand on a garage-front wall? In a toy stiffness model a rigid roof diaphragm gives the garage line less than half, so the flexible split governs; stylised, torsion not modelled.

A 24 x 20 ft ADU composed from the track's models: drawings, bill of materials, IFC, lateral check, envelope energy (a tight envelope cuts modelled heating and cooling cost 36-37%) and a cost index. A worked example, not a buildable design; every input assumed.
• At what climate does each envelope upgrade start to pay, when climate is a continuous axis?At what climate does each envelope upgrade start to pay? Climate as a continuous axis over house-energy's model: slab-edge R-10 from 3,271 heating degree-days with gas (2,386 with a heat pump), 3 ACH50 from 5,769, and cooling alone switches on only the attic and air sealing above ~3,000 cooling degree-days. Stylised: unsourced prices, no solar gain.
• How much extra can a tight envelope cost before it stops paying back on a 480 sq ft backyard cottage?How much extra can a tight envelope cost before it stops paying back on a 480 sq ft backyard cottage? The ADU's whole upgrade package can carry $1,409 to $3,104 of extra first cost (3% real rate, heat pump); at assumed prices only the wall switch clearly pays. Stylised.
• Does a tighter envelope let a 480 sq ft backyard cottage use a smaller heat pump, and is the saving worth counting?Does a tighter envelope let a 480 sq ft backyard cottage use a smaller heat pump? The tight package cuts the design heating load about 36.5%, worth a $450 to $1,800 equipment step credit (assumed catalogue and prices) that nearly closes the payback gap of the costed upgrades in three colder climates. Stylised.
