I still have my notes since the day SNEE was released to the world! I don't think I solved it myself though, remembered following a hint to find my way to THAT "end-point".
Except the Dossier belong to my decease Grandma.
It was more Stable than half the Subnet.
Plus, I wrote them down in my Dossier so I wouldn't have to remember everything.
Its contain more than just the Notes in the SNEE.
Its not all my notes I when I first played SNEE, its was suppose to be my other Layer-Self that is in the Submachine.
Those I threw away.
Its was something on my mind at the time.
But it contain the Answer that the Joker was looking for.
The Secret held by both him and the Thief.
Why is the Word "Watchtower" repeating over and over in my head?
WHERE DO WE COME FROM
WHAT ARE WE
WHERE ARE WEGOING
