Here is another issue: while it's great you have implemented the `/log` command(s) of the WireProtocol, they do not support the return of ANY data that is NOT of the form:
```javascript
{
    "level" : LEVEL,
    "message" : TXT,
    "timestamp" : DATE
}
```

Consequently, returning a HAR JSON as response to the `network` log doesn't really work.

I'm going to change that as part of the merge.
