Updated March 16th, 2024:
Finished my second playthrough (this time executing Pierre) and got screenshots of the remaining endings.
#1. I moved discussion of the determining factors that were previously in "Rebellion Slides (with Pierre)" and put them in a new section called "Determinants for Rebellion Slides." I then thoroughly fleshed out the "Rebellion Slides (without Pierre)" section, included screenshots of all the endings, and detailed what the required conditions are to achieve those endings. I then made some minor revisions to "Rebellion Slides (with Pierre)."
#2. In "Diesel Slides" I added screenshots of the default bad ending and elaborated more on scenarios that result in that ending. I also removed the placeholder for a partial success, since I haven't been able to find one yet.
#3. In "Pantagruel Slides" I added screenshots of the default bad ending and elaborated more on scenarios that result in that ending.
#4. I moved the stuff about the evidence from "Court Slides" into a new section titled "Evidence for the Court." Added a few minor details.
#5. Added a few minor things to "Not Included in the Ending."
#6. Based on feedback from a Steam user, I made it clearer that most of the quests are optional. I also added a mention of various story-related achievements and made it clear that most of those are unlocked immediately and do not require completing the game.
#7. Updated the Red Rabies section to explain what happens if you send Dr. Gruselheim to the Sanatorium.
#8. Updated the Diesel section to explain how to get the scenario whereby the Landsbach ending slides are omitted.
