The mimalloc in PS5MC (PPSA99420) reads vm.overcommit at start-up and
stopped on the unsupported name. It reports FreeBSD's default, 0.

The dolphin_libretro core of RetroArch (PPSA99169) reads {CTL_HW,
HW_REALMEM} as the machine's memory size and stopped on the unsupported
MIB. It reports the same value as hw.physmem.

FreeBSD sysctl_find_oid returns ENOTDIR when the MIB continues below a leaf object. The supported hw.ncpu, hw.model, hw.physmem and kern.arandom MIBs threw an unsupported MIB error instead.
(cherry picked from commit 6968aea8af578c4d56dc614cbe449274bb6e76e7)
FreeBSD sysctl_root rejects a write to a read-only node with EPERM before the node handler checks the MIB length, so a write with a short or long kern.proc.pathname MIB fails with EPERM. sysctlbyname for kern.proc.pathname now goes through sysctl with its 3-component MIB so it follows the same order.
The Python in PS5MC (PPSA99420) reads sysconf(_SC_CLK_TCK) while
importing its posix module and failed with "cannot read
ticks_per_second". It returns FreeBSD's CLK_TCK, 128.

Preserve the leading field and bytes after the 40-byte legacy version record for the values measured in four PS5 firmware 13.42 hardware runs. Keep the emulator version policy unchanged and leave the separately proposed Prospero correction out of scope.
AI-assisted; regression tests are based on guarded hardware measurements.
ScreenTester5 (PPSA69420) stops at start-up on the unresolved sysctlbyname
import and also imports sysctl. hw.ncpu (CTL_HW.HW_NCPU) reports the same
processor count as sysconf(_SC_NPROCESSORS_ONLN). Other names and MIBs throw.
