Kernrechtsfrage
Whether the cantonal court assessed the evidence arbitrarily regarding the debris, ceiling condition, and causal link.
Extrahierter Entscheid
The appellant did not show an arbitrary appraisal of evidence; the cantonal findings were defensible.
Extrahierte Begründung
The expert report largely matched the cantonal findings, and the appellant merely opposed his own interpretation without demonstrating manifestly untenable reasoning.
