+"""Contract test for the didYouMean alert-type class's props.

+The OpenAPI schema (`socket-sdk-js/openapi.json` around line 9298) declares
+that the API emits `didYouMean` alerts with ``props: { alternatePackage,
+detectedAt }``. The Python SDK previously declared four props
+(``alternatePackage``, ``downloads``, ``downloadsRatio``, ``editDistance``);
+the latter three are no longer in the API schema and were dead keys at
+runtime — and ``detectedAt`` was missing.
