Questão jurídica principal
Whether the cantonal court arbitrarily found that the parties initially agreed that the appellant would provide a metal connection.
Decisão extraída
The finding was sustainable because it was based on concordant witness testimony and the written offer did not decisively contradict it.
Fundamentação extraída
The Federal Court held that the cantonal court could prefer precise, consistent testimony over the incomplete written offer; no arbitrary fact-finding was shown.
