[SPOILERS] Are the chioces even tracked by the game at all?

[Omnitool]

I remind you all that this thread was meant to discuss whether anyone has found any evidence that the game tracks / records the player's choices, by techincal means (reverse engimeering).
This can be done by comparing the size and other properties of two identical savegames made in the same in-game moment, but after making different choices (try to compare a savegame file from right after you kill the WAU to another one where you do not kill it) or examining the code in the savegame files (with Notepad++, a hex editor, or any other method), and examining the game files (level maps, textures, models) for hints of a possible alternate ending or for the player choices influencing the game in any way (enemies placememt, lights, doors closed / opened, etc).
