> Reboot is not enforced by the SEP, though, only requested

We (the public) do not know if SEP can control nRST of the main cores, but there is no reason to suspect that it cannot.

We actually do know, it cannot directly*. What it could do is functionally disable RAM, but that would basically cause the phone to hard lock and even cause data corruption in some limited cases.

This is still being actively researched. I have no evidence, but would not be surprised to find out that a SEP update has been pushed that causes it to pull RAM keys after the kernel panic window has closed.

* This may have been changed since the last major writeup came out for the iPhone 11.

iPhone 11, the one 5 years ago? So yes, you have not at all refuted my statement for any recent phone
