You have some interesting criteria for what constitutes perfection. You didn't consider my interpretation involving a wormhole to be perfect, arguing that the GM would hardly devise such a logical path, deciding to link a clue to Yashur's avatar. But here, the GM's path would be: "National Park" in Ment's profile ---> some random national park in Cuba ---> Che Guevara landing there among other revolutionaries ---> a random quote from Che as a clue. Isn't that significantly more likely than the stars and the wormhole?)
