D1 chaos

With some more experimentation and reverse engineering, here is my current understanding of how chaos works:
1. Chaos goes up and down in increments of 6.
2. There are several categories of NPCs: Civilians, Thugs, Guards, Tallboys, Weepers and Assassins.
3. Killing a Civilian gives you 6 chaos.
4. Every 4th Thug, Guard, Tallboy, Weeper or Assassin you kill will give you 6 chaos. Note that these are tracked individually, so killing a guard and three thugs will not give you any chaos.
5. Certain actions, like poisoning the distillery, will give you 6 chaos.
6. Certain actions, like freeing Sokolov's test subjects, will take away 6 chaos.
7. Triggering 5 alarms or having 5 bodies discovered gives you 6 chaos. Again, these are tracked individually.
8. The categories are not necessarily tied to how they show up on the End of Mission screens. For example: The Pendletons count as Civilians, and killing Granny Rags does nothing, although she shows up as a Civilian.

THRESHOLDS FOR CHAOS
---------------------------------
High Chaos Prison: 12
High Chaos Campbell/End of Cat dialogue: 48
High Chaos Cat: 72
High Chaos Bridge: 96
High Chaos Boyle: 114
High Chaos Tower: 138
High Chaos Flooded: 162
High Chaos Loyalists/Lighthouse: 168
Really High Chaos: 390
200 is also mentioned, I don't know where it is used
maybe to check for some dialogue, maybe a remnant
Yes, it is completely possible to get the low chaos version of lighthouse but still have it say high chaos when completing it
you lose 20 chaos from sparing daud
killing daud gives you 6 chaos
I believe those are the only chaos levels that matter
