Now that I'm two books ahead of this one, I get to fix the occasional problem that conflicts with later books. The more interesting or engaging version of the narrative always wins. (So yet, I am retconning even before publication.)
On an amusing note, Jenny sometimes makes a note, such as "this explanation strains credulity." I solve those by having a character say, "That explanations strains credulity." Basically, the characters proceed to call the bullshit or otherwise spot the stupidity. I don't explain it better.
