[+] unprivileged debug.panic write BLOCKED: rc=-1 errno=1 (Operation not permitted)
[+] the uid-0 capability gate (SYSCAP_NOSYSCTL_WR) holds for non-root.
[+] NOTE: prison_priv_check() returns 0 for SYSCAP_NOSYSCTL_WR (kern_jail.c:885),
    so a jailed root CAN write these -- the jail-confinement gap is real.
