Damn kids with your twitternets and me mes.

Germany hasn't officially endorsed ChatControl, and groups like Hetzner outright oppose it.
In the US, ChatControl takes the form of the LAED Act and the EARN IT Act.
All three focus on this appeal to emotion that to protect kids we need to get rid of end-to-end encryption.
Legislators are pretty fucking dumb when it comes to this stuff, though.
They don't understand that if they have a backdoor to encryption, everyone has a backdoor to encryption.

that would require sitting down and manually doing that for every conceivable payee

That's just called VLOOKUP(). I think you're over-complicating this process. If you sit down and look at your finances, you'll notice that the number of payees you have isn't some absurd unmanageable amount. As others have mentioned, there's no real use case for involving AI this way. There's no scale, no real benefit to financial tracking, etc. I get this is just to use AI for the sake of using AI, but that's not really goal when writing financial software.

Honestly, you don't even need NLP for this. Excel supports regex now so you could just do a call like =REGEXTEST(A1, "(?!)^w.*mart$"). Then just mark by type and graph out to see where your main spending is coming from.

Germany's legislation is largely spearheading the effort. They aren't trying to build the infrastructure to support it, they already have the infrastructure. They are one of if not the biggest GDPR actors and have a large datacenter presence through companies like Hetzner and DE-CIX.

I'm sorry, its been a long day.

DNS4EU doesn't provide DDNS service, you are correct.
Checkout deSEC, they partner with DNS4EU and the EU as part of the initiative to limit dependency on US based infrastructure.

You might try DNS4EU:
86.54.11.1
86.54.11.201

DoT: protective.joindns4.eu

I'm familiar with V:tM and some Mage, but nothing Werewolf. I do have a technical background though.
AI hallucinations have already been explained in the comments, but one way you could approach this is through the use of what's called cognitive hacking. Its a subset of social engineering that mostly focuses on things like rigging elections instead of getting people to hand over passwords and such. You manipulate content, spread disinformation, and insert narrative driven data.

Its an interesting tool in that you'd be in effect hacking your players.
You might read up on a base intro to it:

One tip to make it more successful:
You can't make someone think positively about something they already have an established negative belief about.
You can however widen that gap and work to re-enforce their negative belief.
Its the key to radicalizing people and lets you plot out what their actions will be (effectively railroading themselves without knowing they are).

I had a similar setup to this awhile back. You have to port the number to your VoIP provider of choice and then decide on what client you are going to run (no need for SIM card). I was wanting voice service and only needed limited SMS, so I went with linphone (and played around with zoiper too). If you are needing good SMS support, then JMP is probably the best. It supports both SMS and MMS. You won't get E911 access I believe, but as data only its a good solution.

Free wifi is all over the place and if you wire up a mobile hotspot in your car (yes it somewhat defeats the purpose), you can get some pretty decent coverage.

No, installing Tailscale on all machines is not actually required. You can setup a funnel that exposes a service to the internet for all to see. This also removes the requirement for them to access via Wireguard if desired. https://tailscale.com/kb/1223/funnel
