Serial = SHA256(name + monotonic/mouse entropy + wall-clock sec + screen dims), so it changes every run. Raw syscalls, so no LD_PRELOAD faketime.
Escape hatch in main:
if (clock_gettime(CLOCK_MONOTONIC,&t) < 0) { v26 = 0xEE18D70B34696718; ptr=(0,0); }
If that read fails, the whole timing/mouse loop is skipped → entropy becomes a constant and pointer=(0,0) forces the deterministic screen-dims branch.
Can't patch/hook/inject the binary — so I filtered it at the kernel: seccomp-BPF returning EPERM only for clock_gettime(CLOCK_MONOTONIC), CLOCK_REALTIME allowed. fork → install filter → execve the untouched ELF (filter inherited).
Now everything's deterministic. Reimplemented the math (FNV → splitmix64 → 16-round mixer → SHA-256), read monitor size via Xrandr, used the current second, fed the serial back same-second.
Croak! Correct serial.
