You should ask about whether a number is positive or negative this way:
IntegerRangeType::fromInterval(null, -1)->isSuperTypeOf($offset)->yes() // is negative
IntegerRangeType::fromInterval(1, null)->isSuperTypeOf($offset)->yes() // is positiveIt also accounts for unions of ConstantIntegerType, like 1|3.

does this mean I should check for a zero offset with
IntegerRangeType::fromInterval(0, 0)->isSuperTypeOf($offset)->yes() ?

You can check for that with:
(new ConstantIntegerType(0))->isSuperTypeOf($offset)->yes()
