Additional context

All of the failing tests initialize the value as decimal with a dot separator:

value = GetObject((name: "value", value: "4.5"));
Assert.True(assert.Greater(value, "value", 2, convert: true).Result);

When regional format is set to en-US, the tests pass:

cd PSRule
dotnet test
...

@codepic Thanks for reporting the issue.

Instead of . how would this normally be represented with your recommended culture settings?
