// This query is not expected to have inputs -- as a result, it's
// not a good candidate for "replay" because it's essentially a
// pure function of its input (and hence the expectation is that
// no caller would be green **apart** from just this
// query). Making it anonymous avoids hashing the result, which
// may save a bit of time.
