I was already thinking about that and I'm not yet sure about the best
solution. Feel free to propose one. (You cannot solve all problems in
proposal though, so it's not that bad if you just plan the time to
think about the best solution :)

Git logs.

It won't be the end of the world if removal is delayed for a day.

What would be a mediator? Independent script? Your app?

I'm not particularly eager about this idea.
Relying on the buildbot to keep random logs for you is way too fragile
and you have absolutely no control of the build master, so if you'll
want to get something changed, to delete some file, to update the
format ... how will you take care of that?

It might be ok to have 20 logs per port at maximum. But it might be
that the port was last built "40.000 builds ago".

Rainer recently implemented the functionality on our build master that
sends feedback to GitHub:
https://github.com/macports/macports-infrastructure/commit/d9aeeb32b22a06eb39f1a0317869e9c12e3ed021
It could do something similar for this website.

I don't understand this question. Which backend and which website?
