just a quick example from the backtracking section:
"Here's the dirty secret of WFC: it fails. A lot. You make a series of random choices, propagate constraints, and eventually back yourself into a corner where some cell has zero valid options left. Congratulations, the puzzle is unsolvable."
Besides what others said. The "The Numbers" section is a dead giveaway. LLM likes to generate random summary stats in a metrics grid without any prompting.
