@clew and that’s hard!!! Clairvoyance-test-passing questions are tricky, and I’m reminded of how the early Lisp papers published in the 1950s are riddled with programming bugs because the authors lacked computers to run the code on.

But suppose we want to know when the CPC will fall. What do you mean by “fall”? Interregna come in a dizzying variety of shapes, including total or partial collapse of the central government, warlordism, shrinking of the government, etc.
