[Structured binding](https://en.cppreference.com/w/cpp/language/structured_binding) allows you to name the pair elements directly, which I think help readability (you might know of better names than `Key`/`Value`). I'm not sure if this will work here or in the rest of this PR, but it's worth a try.

```suggestion
    for (auto &[Key, Value] : make_range(TidIter))
```
