Server SDK - follow-up action on discard of changeset
Accepted answer
I am not aware of any process being available on workspace modification actions, since workspaces do not belong to project areas, and all process is defined in project areas.

The checkin-event is an example of an event on a workspace which can be extended.

The issue is, that the discard does not do anything to the change set itself. It just removes it from the stream or workspace. You can trigger on save change set, but not on discard.
To expand on Ralph's comment, a checkin-event is treated as an event on a component and therefore the process can be obtained from the project area that owns the component. Note that if a component is owned by a user rather than a project area, you cannot define checkin-events on that component.
