Where are the reference answers for CTF/uboot? (aka Challenge 10)

[henrygab]

The challenge is archived at:
https://securitylab.github.com/ctf/uboot/

The links to Check the reference answers and Official contest rules simply re-open the exact same page.

Looking at another CTF challenge https://securitylab.github.com/ctf/jquery/,
the answers can be found at https://securitylab.github.com/ctf/jquery/answers/.

However, applying that pattern does not work for the uboot challenge:
https://securitylab.github.com/ctf/uboot/answers/

So... where are the reference answers? I'm trying to improve my CodeQL skills, and this challenge seems at the right level (I learn a bit at Q1_0), so any pointers would be appreciated.

Thank you!
