I believe they are higher dimensional string diagrams. Maybe called n-diagrams? They are used in higher homotopy and higher category theory, I believe. But not entirely sure.

EDIT: Found it! they are called surface diagram, which are generalization of string diagram to 3-categories https://golem.ph.utexas.edu/category/2010/03/modeling_surface_diagrams.html https://ncatlab.org/nlab/show/surface+diagram
Still not sure what the proof is talking about though :(
But from the conclusion it looks like some sort of natruality condition, where the morphisms are slided around except beta.
EDIT AGAIN: got in touch with my string diagram contact. Here is the paper https://arxiv.org/pdf/0807.0658
Note the conclusion at the bottom, the proof on the right and the axiom on the left doesn't seem to be related.
The proof on the right is Theorem 6; the equality at bottom is in section 3.4, where the proof is omitted because "follows from definition"; the axiom on the left is HM1 and HM2 on page 19.
If you search about it you will find https://www.youtube.com/watch?v=oR_RAp73ra0 She also talked about trans-athletes https://www.youtube.com/watch?v=cZ9YAFYIBOU
I have never watch it, and not planning to, so I cannot help you summarize it. Nor have I claimed that she is transphobe, so I don't feel the need to justify that stand.
If you choose to ignore everything else and focus on this one issue, then I have to admit I don't know much about it.
I am more and more tempted to donate to EFF every single day.
She has growingly appeal to right wing / corporate rhetorics to attract viewers:

One of her more controversial take is that academia failed because it is "communism", and we should privatize science to let corperate and youtube viewers to decide who to fund instead of expert commitees: https://www.youtube.com/watch?v=htb_n7ok9AU
They do need to pay developers to get high quality software, which is especially for a message app centered around security.
That is package right? Most people will not get the full benefit of the package, the cash is usually around 150k, plus the cashable part of the package it would be closer to 200k for most.
LLM is very good at programming when there are huge number of guardrails against them. For example, exploit testing is a great usecase because getting a shell is getting a shell.
They kind of acts as a smarter version of infinite monkey that can try and iterate much more efficiently than human does.
On the other hand, in tasks that requires creativity, architecture, and projects without guard rail, they tend to do a terrible job, and often yielding solution that is more convoluted than it needs to be or just plain old incorrect.
I find it is yet another replacement for "pure labor", where the most unintelligent part of programming, i.e. writing the code, is automated away. While I will still write code from scratch when I am trying to learn, I likely will be able automate some code writing, if I know exactly how to implement it in my head, and I also have access to plenty of testing to gaurentee correctness.
I think on android, signal do not use Google's push notification. They simple send a dummy push, and the signal app wakes up to retrive the latest message directly from signal server.
So Google never have your notification content. I am not sure if they do the same on iOS.
That being said if your attack model includes people reading your notification lock screen, then you should disable showing signal notification.
Usually, I spend $40 in a buffet, annihilate all their snowcrabs, then spend an hour next day on to toilet until my leg is so numb that I can barely stand.
Do I care? No, because I have made it: I make more than minimum wage now.

The article says the document is not send to a third party, most likely it uses info on the passport (NFC, not photo) to generate a proof that the holder is an adult.
