You are clearly missing the point. The alleged crime of falsifying business records is an expired misdemeanor. The only way to revive it and convert it into a felony is to allege and prove that the falsification of business records was in furtherance of another crime. That "other crime" is not in the indictment, nor has it been defined by the prosecution or the judge. The fact you cannot see how crazy and unfair it is to put someone on trial without telling them exactly what they are accused of is telling. This is one of the worst violation's of due process I've ever seen.
You should read Franz Kafka. That is exactly what they are doing to Trump.
175.05 does not appear to be expired according the NY penal codes. It is still on the books as a misdemeanor. 175.10 is a felony. If you know otherwise, please provide a link showing it is expired?
