Hey, I've been running immolate with the existing, unmodified filter perkeo_observatory and I received these 4 seeds:

11NY1GGZ1 (1)
11NYJX7N1 (1)
11NZMRY61 (1)
11NZPGCM1 (1)

When analyzed using https://mathisfun0.github.io/The-Soul/ I see the first seed only has soul at ante 5, and the other 3 don't seem to have a soul card in the first 8 antes at all.
For context I'm running Immolate on an Ubuntu 22.04 VM, the command that yielded these results was run like this: ./build/Immolate -f perkeo_observatory -g 12 -s NOGFROG, and this is the output of immolate --list_devices:
