Detailed Description

A join on the slots table, mostly to support requireSlotChanged().

There can be multiple slots for a given change, which is dealt with here by restricting the join to a specified role.

We also provide an alias for a the slots of the parent revision of the change.

This could be generalised if there was a need to do so.
