Is there anyone in the company that you can just ask these questions of?
Not as a complain but to genuinely ask why these things may have happened and how it is making your job challenging, furthermore how it is also making you feel that you are being siloed.
You aren't going to get a solid answer here, but only from the people you work for.
I appreciate the point about directing these questions to the source, and you are likely right that I'm unlikely to find any concrete answers here.
To answer your question, it feels like I did ask why the decision was being made but the response was vague- essentially, I was told to focus on testing. I'm wary of pressing further, as it risks being interpreted as pushback rather than a legitimate concern about efficiency. This would be a non-issue if I were communicating with technical leadership but given the lack of technical understanding from those making the decision, there’s a real possibility that further questions would be dismissed or viewed negatively.
