"Everything" is a bit optimistic from my understanding.

I would like to know
how does the pairing work?
what files are modified?
is it on the console or in the drive itself or both?
What's stored in a backup that doesn't keep the pairing, or does it?

And that's just starting.

Good idea, but the word "everything" doesn't quit fit the description for me.

Fair. My understanding is:
1) PSN servers generate a unique key based on the drive that the console accepts. The console can not generate this key on it's own by design.
2) Not sure if this is known or documented anywhere publicly anyways yet. I hear people are working on reverse engineering it.
3) It's definitely at least on the console side in some capacity, which is why resets are fine on a PS5 Slim Disc Edition that is factory paired, but it looses this if you wipe the whole OS. PS5 fat Disc Edition must be storing it differently since it can never loose the pairing.
4) Backups never affect pairing under any circumstances nor does it store any pairing.

I read from another post that you can back up the bd pairing information using https://git.etawen.dev/earthonion/ddd_pair_dump/releases.

Has anyone tried this successfully? I tried running the payloads on my PS5 pro but it doesn't seem to generate any files to backup. Or does it only work on slim models?

I have a PS5 Slim Disc edition that I just had to reset to factory settings from safe mode after a crash when playing a backup that was installed in the internal SSD after using the P2JB > unpatch patch disc drive > BD-JB method.
I was able to reset to 12.0 firmware but now my disc drive needs to be registered, I assume this means connecting to Sony's server and update to the latest firmware.
Does it mean I can't use BD-JB and my disc drive anymore if I want to continue using jailbreak ?

Did your Slim come with a pre-paired drive?
What was the factory firmware version on your PS5, and has it ever been updated in the past?
What exactly do you mean by "reset to factory settings"?
Once the drive pairing is gone, it's gone, it's pretty much impossible to restore it without updating to the latest firmware and online pairing.

I bought the Slim 2 years ago. Don't remember what was the factory firmware but I also don't remember having to pair the drive when I first plugged it in (note that the PS5 is currently asking me to register the drive, not to pair it).
I have regularly updated it until september 2025 and been on 12.0 since then.

After the crash I encountered today, I was basically stuck on Safe mode. 8 options were displayed on screen and only the last one was available to select : 8 - Reset PS5 (Reinstall System Software). So I did what's described here : https://www.playstation.com/en-us/support/hardware/reinstall-playstation-system-software-safe-mode/ using a 12.0 firmware I found online.
