It seems Isabel was "verified trans," and had sensitivity reading done. As lived experience is the metric that matters here, and then she/they got the additional verification done, that's the full stop here. She/they lived it, she/they got sensitivity readings done, and QED she/they can write about it... at least as the current rules go. All your points largely summarize to there being some suspicious aspects to her/their identity, and because of that, shoot first and ask questions later was apparently ok. "Because we as an industry are hyper tuned to any slip up on these key metrics, let's verbally slaughter whoever has some oddities to their author profile regarding these metrics." Given that Isabel ended up in a hospital, as you said, the lack of introspection from the publishing community once the facts of the matter came out is ugly and why many authors are terrified for their careers.
