What do the files in the "profile_" folders do?

[Colonel Vance]

After finishing the storyline I decided to maybe start creating some mods, but before I do that, I wanted to take a small break and study how the game works in its entirety. I noticed the files within the "profile" folders, but apparently I cannot read the content of those .json, so I'm kind of trying to guess what each of those do.

These are the ones I am almost sure about:

• novelty_tracker.json = simply handles when the ! icon is displayed on new items/things.
  
• persist.campaign_log.json = handles what appears in the log you can see from the Hamlet
  
• persist.curio_tracker.json = handles how many crests, busts and deeds you have
  
• persist.game.json = I guess this one keeps track of the savefile name, difficulty and settings
  
• persist.journal.json = the journal pieces you collected so far
  
• persist.narration.json = keeps track of which lines the narrator has already spoken
  
• persist.roster.json = keeps track of all the heroes in roster, possibly including dead ones
  
• persist.town_event.json = list of all town events and their cooldowns
  
• persist.tutorial.json = the tutorial popups that have appeared so far
  
• persist.upgrades.json = the upgrades you have on your armour and weapons

But I am unsure about the following:

• persist.campaign_mash.json = totally no idea
  
• persist.estate.json = I'd say it's about what buildings are locked, OR the state of the Darkest Dungeon run
  
• persist.game_knowledge.json = totally no idea
  
• persist.progression.json = I think it's either the amount of XP each character has, or the progress within the Caretaker goals
  
• persist.quest.json = probably keeps track of how far you went with the Darkest Dungeon quests.

If you have any info on those files, please let me know.
