A construction after the fact

Do you think the highlighted sentence means:

1. all case histories are constructed on the basis of the facts that have happened in the past

or

2. all case histories are constructions that look for the fact?

Context:

While artists like Bourgeois and, as we saw in the previous chapter, Max Ernst make statements that impose a psychic narrative on their work, these case histories have to be taken as semifictional in the sense that all case histories are a construction after the fact and are themselves a working through of fantasies and desires in a literary rather than a visual medium. It is crucial to resist as much as possible the tendency in our culture to latch onto words as having the power to explain art. I see Bourgeois’s statements and her work as different instances of working through childhood trauma, the artwork being fantastical elaborations of psychic processes that result in objects and scenarios that are wonderfully in excess of her autobiography, although they could be said to mine it for inspiration.
