> All but one of the programs cited in her notes had been prepared by Babbage from three to seven years earlier. The exception was prepared by Babbage for her, although she did detect a "bug" in it. Not only is there no evidence that Ada ever prepared a program for the Analytical Engine, but her correspondence with Babbage shows that she did not have the knowledge to do so.

The common claims are that Ada Lovelace was the first person to write a computer program, or that she was actually the primary driver in developing the analytical engine. Both such claims fall into the area "DEI retcon" as you choose to phrase it.

Although on a more pedantic note, Babbage wasn't the first person to program a computer either. Computers that aren't Turing complete are still computers. The Jacquard loom is one such example, and unlike the analytical engine it was actually built and put to practical use.
