"Dieselpunk transhumanism" is a criminally unexploited concept.
This is where the RTFM mindset is important. If you encounter an issue, there's multiple decades' worth of information on the internet that will most likely immediately provide an answer.
The location of installed files is determined by long-standing conventions that were in effect even before Linux was released... but I won't go into it. You can read about it yourself: https://en.wikipedia.org/wiki/Unix_filesystem
This is my point: do you need to know this? Nine out of ten cases, this is not useful knowledge. I'm a sysadmin and even I don't need to know where each program's files are located. You should not be interacting with these files at all. Let a package manager do that.
At the same time, I've seen people use their Steam Deck as a server.
To delegate the responsibility of securing login data to a company better equipped to deal with it (in theory at least). You can also use an external OIDC provider.

Destiny is on life support, Hunters Gathering is dead on arrival, Marathon's future is bleak, Concord is Concord, and the one studio that could've printed them easy money is dead because the sorry excuse of a circus that is Sony leadership really wanted a live service God Of War title. Gee, I wonder why sales are low.
I bought my current car with ~69000 kilometres in it (which may or may not have influenced my choice), but got complacent and missed 80085.
Tailscale. Create an account, put the client on the LAN device, put the client on the remote device, log in on both, you're done. It bypasses NAT, CGNAT, and the firewall through some UDP black magic fuckery. As long as the router allows outgoing connections, it will work.
If the factory resets cause the router to lose connection to the ISP, though, then nothing will work.

You're approaching the game from the wrong angle. Progression doesn't reset because there's no mechanical progression. The only way to make progress is to uncover more of the story so you know where you should be looking in the next loop, or how to get around an obstacle. It's a metroidvania of information.
