"""Qualify the offline process table that reaches SpringBoard.

The one-shot observer reads the kernel allproc list at the bounded timeout.
|
|
Names and PIDs are read from the actual struct proc linkage; no breakpoint or
|
|
userspace instrumentation is used. This proves the original userland stack is
|
|
alive, not that a display, GPU, desktop or hardware path exists.
