### The problem

It would be nice to be able to see when domains are resolved for the first time inside of the query log.

### Proposed solution

You can store these occurrences inside of their own table. Most resolutions are residual so this would not be very expensive to query.

### Alternatives considered and additional information

Accessing the data manually.
