I am a bit confused by the result I am seeing from ‘min’ or ‘min\_over\_time’

For example I have metric ‘up’ for the status of an exporter target.

```auto
up{instance="target"}

```

The result is `'0'`

This is expected, the target is down.

Next is where it goes wrong…

```auto
min_over_time(up{instance="target"}[1h])

```

the result is `'1'`

I also tried

```auto
min(up{instance="target"})

```

but this also comes back as `'1'`

Where is it getting ‘1’ from, especially as a minimum?
