DF-3009 baseline run (stock kernel #0 Thu Jul 2 06:02:54 UTC 2026) — full output:

    MOUNT_OK

(The `stat /mnt` that follows in run.sh panicked the kernel before any
further output could be produced; the ssh session died with the guest and
the orchestration wrapper reported its 120s timeout. The decisive serial
console capture — Fatal trap 12, fault VA 0x10, Stopped at
nfs_reply+0x622: movq 0x10(%rax),%rax, current process = stat (pid 1087) —
is in panic.txt. `vm.sh status` -> down immediately after.)

fakesrv log excerpt (guest /tmp/fakesrv3009.log, VERBOSE off) confirmed the
kernel RPC arrived on the nfs/TCP listener and was answered with the 4-byte
mark; the mount handshake (rpcbind GETPORT, mountd MNT, NFS NULL ping) was
answered honestly, hence MOUNT_OK.
