+[TIP]
+====
+Terms that don't qualify as semantic anchors can still be useful as link:#/contracts[Semantic Contracts].
+A contract defines what a term means in your project — either by composing established anchors or by providing custom definitions that only exist within your team.

+====
+Begriffe, die nicht als Semantic Anchors qualifizieren, können trotzdem als link:#/contracts[Semantic Contracts] nützlich sein.
+Ein Contract definiert, was ein Begriff in deinem Projekt bedeutet — entweder durch Komposition etablierter Anker oder durch eigene Definitionen, die nur in deinem Team existieren.
