Kernrechtsfrage
Whether the cantonal court correctly assessed the invalidity degree under the mixed method, especially the household component and interaction effects.
Extrahierter Entscheid
The household impairment remained 21.5% weighted at 8.6%; no relevant interaction effects justified a higher deduction in the household area.
Extrahierte Begründung
The court found no evidence that half-time gainful work would additionally impair household tasks in a two-person household, so the 21.5% household limitation stood.
