I have a scoop! Courtesy of someone who I don't want to get in trouble but does work in a company that has a Doctor Who license I have been told the official BBC restrictions for dealing with the Fugitive Doctor. (Which I assume would have to be Russell's restrictions.)
To wit: While she is definitely the Doctor, since the Master can't be trusted the truth of their past remains a mystery and is not to be touched on. Specifically no mentioning the Timeless Child or using Tecteun. Division can be used but shouldn't be the main focus of a story. And finally in a rule that has to have been written especially for Big Finish no having her meet other past Doctors.
Definitely the best solution as far as I'm concerned. Despite what some folks might have wanted there was no way they were ever going to un-Doctor her, so just avoid the stuff that people realllly disliked. (Just like how there's been hundreds of 8th Doctor stories at this point with the half-human subject being steadfastly ignored.)

? Tecteun wasn't a great character, why Jo's Doctor has to be tethered to The Division all the time seems a waste of opportunity and potential, and I'll admit that hearing or seeing Jo spar opposite Colin or Sylvester would have been pretty cool... The Master altering the Matrix or setting up a big fib is so much in character that "not to be trusted" fits perfectly
