[Bug]: DataResultAssert.extractingValue() annotated @NotNull but can wrap null

Module: testkit
File: testkit/assertion/DataResultAssert.java (~line 329)
Severity: Low

Summary

extractingValue() is annotated @NotNull but calls Assertions.assertThat(this.actual.result().orElse(null)), potentially wrapping null. While isSuccess() is called first, the @NotNull annotation on the return type is misleading.

Suggested Fix

Use orElseThrow():

return Assertions.assertThat(this.actual.result()
    .orElseThrow(() -> new AssertionError("Success result contained no value")));
