I'm putting up a github issue on this, but I figured a discussion thread would be good.
tl;dr of the issue:
1: the deca-code mastermind puzzle is a pain in the arse.
2: It's such a pain in the arse that people are skipping the puzzle entirely and just blowing crates open, usually by asking engineering/xenoarch for an emitter.
3: once they get an emitter there's been a couple of times that they've gone straight-up guncargo 'cause access restrictions no longer matter.
So basically the "puzzle" has turned into "might as well just be access-locked as far as miners are concerned" which has a knock-on effect of "miners need to be able to bypass access locks, possibly using lasers", which leads to "miners can order actual guns and open them when security aren't looking".
So, basically this comes down to two real problems:
1: puzzle is dicks.
2: bypassing the puzzle entirely with a gun/emitter is easy and risk-free.
To solve part 2 of the problem, how hard would it be to have the explosion trigger upon shooting the crate? May require a special class of "secure crate" to be created. (with bonus of being able to put some cargo things in that class, like military-grade weapons. Emaggable, yes, but shootable no)
For part 1, that's the tricky part. Anyone got any ideas for a simple RNG puzzle?
Main criteria are that it should be reasonably guessable without a tool, but not instawin if you do have one.
