Its basically like a cloud storage, and your local storage (your brain) gets wiped every loop. You can edit this file any time you want using your brain (you can be tied up and it still works). 1024 Bytes is all you get. Yes you read that right: BYTES, not KB, MB, or GB: 1024 BYTES
Lets just say, for this example: The loop is 7 days form a Monday 6 AM to the next Monday 5:59 AM.
How do you best use these 1024 Bytes to your advantage?
How would your strategy be different if every human on Earth also gets the same 1024 Bytes “memory buffer”?
But the first time the loop starts, how would I ever know to edit the file?
If the brain HUD thing is new, and I suddenly am able to edit a file, I might use it for random stuff. Once the loop happens, I would have a text file with whatever random things I put in there during the previous week, with zero context.
I might be able to determine that it’s my own writing, depending on the language used.
If I’m able to tell that it was things pertaining to my upcoming week, I might conclude some kind of time fuckery; if I knew it was my own writing, but couldn’t figure out the context of when I wrote it, I might assume I’ve lost my mind.
If the former happens, that’s when I’d probably start testing; whatever day I “discovered” the file would be the reset day, I would try leaving a note to myself about the time loop and indicate the date just before that day (in the example given, Sunday before the second loop).
Once I wake up on a reset day with a text file giving me the last date before the reset and a message explaining what happens, I would know about the loop, and roughly how long I have until it happens again.
