if it is, in fact, something nefarious at play that would be a pretty crazy 2026 era exploit. but i'm certain it's a bug/artifact of some sort that, for whatever reason, affects this specific app.
It's hard to imagine what Headspace would like to achieve if this were an exploit executed by them. It's so salient, that it makes no sense to do on purpose. At least some portion of Apple employees and their families are going to be affected by this, and this would escalate to the legal department immediately.
My money is on Apple being the buggy one here.
Yeah I'm thinking some sort of test artifact bleeding into prod and subject so some nightly process is likely the case.
