nobody:

me: they never told greg weisman that jace beleren does not actually live inside the chamber of the guildpact, so in the book he interpreted the building as “embassy of the guildpact” (which isnt and has never been a thing) being the name of the whole building and the part where guild members meet, and the “chamber of the guildpact” being jace’s home, within. the chamber of the guildpact is in fact the name of the entire building, and jace’s home is somewhere else in the tenth district, connected to the chamber of the guildpact by secret tunnels only he and lavinia know about. it is also impossible for jace’s home to be inside the chamber of the guildpact due to the fact that it has a rather large rooftop garden courtyard overflowing with plants, something that the dome-shaped roof of the chamber of the guildpact obviously does not possess. in the war of the spark novel it’s written that jace’s library got sliced in half by the opening of the planar portal, but that wouldnt have happened because jace’s library and home are not inside the chamber of the guildpact. nobody corrected this error, though, so jaces home is now destroyed for basically no reason
