hammerspoon: "internal.so" cannot be opened because the developer cannot be verified

I’m encountering ‘“internal.so” cannot be opened because the developer cannot be verified’ for the hammerspoon _asm spaces module. Unsure what could be causing it. This is a new computer, but I had just set this all up on another new computer last month and it worked fine.

asked this yesterday, but think my client messed up, so lost all the history. 
Unable to find anything in the github issues, but I'm encountering '"internal.so" cannot be opened because the developer cannot be verified' for the hammerspoon _asm spaces module. Unsure what could be causing it. This is a new computer, but I had just set this all up on another new computer last month and it worked fine.this is on Catalina btw.

snowe2010: that's macOS being secure at you :/
where did you put the internal.so?

it's just in my dotfiles, then I symlink the hammerspoon folder. let me link my layout.

hmm, I thought we specified that we wanted to be able to load arbitrary library files

internal.so is here https://github.com/snowe2010/dotfiles/tree/master/hammerspoon/hammerspoon.symlink/hs/_asm/undocument...

Ng, anything I can dig into here to figure out why this is happening?
Ng
10:04:09
snowe2010: sorry, I'm not sure. I know why this is happening, I'm just surprised that it is
we moved to the new macOS hardened runtime, but I'm sure I applied the setting for "allow loading unsigned libraries"
your easiest option would be to downgrade to HS 0.9.75
but there may also be things you can do to break HS' code signature, thus disabling some of these checks

hm.. found the same issue here, https://developer.apple.com/forums/thread/115451, where it sounds like they did the same thing but had the same error.

I install using homebrew, maybe that's part of the issue? that makes it more difficult to downgrade though.
Ng
10:47:54
ah interesting
it could be that asm's build is too old
Ng
10:49:17
snowe2010: could you run: otool -l /Users/tyler.thrailkill/.hammerspoon/hs/_asm/undocumented/spaces/internal.so | grep -B 1 -A 3 LC_VERSION_MIN

blargh, that looks bad. need me to post in pastebin? I'm using kiwi right now as this is a brand new computer and don't have weechat setup...
Ng
10:50:49
no that's fine
but it blows that theory out of the window, because 10.10 should be new enough
snowe2010
10:52:07
:(
Ng
11:00:53
snowe2010: would you mind opening a github issue? in the worst case, I'm happy to codesign asm's build

❯ otool -l /Users/tyler.thrailkill/.hammerspoon/hs/_asm/undocumented/spaces/internal.so | grep -B 1 -A 3 LC_VERSION_MIN

Load command 8
      cmd LC_VERSION_MIN_MACOSX
