Sakuwa Control Ledger · hosted by TacticalPrompt · Episode 4
The famous numbers were all right. What broke was a single character — measured at a Korean fortress
Using the Suwon Hwaseong beacon tower, one run of the same controlled experiment as chapter 2 of vol. 2. Condition A (summary only): 2 confabulations. Condition B (with ledger): 0.
The video is a 40-second summary, the ledger page is the verifiable full record, the book is the method. All three point to the same single experiment.

Honesty guards
- The two generators ran in contexts separate from the auditing session but are models of the same family. The only controlled variable is whether the ledger was supplied.
- A single run (n=1). “Reproduced” means consistency with the book’s conclusion, not a statistical claim.
- The 興天/興川 verdict rests on the “興天山” spelling in the Pyeongtaek Citizens’ Newspaper. The Uigwe original was not checked directly.
