Example 1: Runner sucessfully runs at HQ which has an installed upgrade.
Does the runner choose to access a random card in the corp's hand or the upgrade or can he access both?
i.e. On success does the runner access HQ or the HQ Core or both?
Example 2: Runner sucessfully runs at a secondary server which has an installed upgrade and an asset.
Does the runner have to opportunity to trash both or just one of them?
