Alina felt the floor drop away. “That’s insane. That violates every principle of SEM. Coefficients are supposed to reflect real relationships, not be arbitrarily unique.”

Erik’s fingers trembled as he paused the algorithm. They both stared at the number: 0.899. Impossible for that indicator. The survey item was “I feel guilty when I throw away food scraps”—a perfectly reasonable question, but in all prior runs, its loading had never exceeded 0.73. smartpls 4

The last ten thousand lines were gibberish. Not errors. Not code. Gibberish. But threaded through the nonsense, repeating every 47 lines, was a sequence of numbers: Alina felt the floor drop away

He spun his laptop toward her. On the screen: a PLS-SEM model of staggering complexity. Fifteen latent variables. Two hundred and forty-three indicators. Moderated mediation pathways crisscrossing like a plate of angry spaghetti. Coefficients are supposed to reflect real relationships, not

“I found a ghost ID in a dataset. Pi in the log files. Path coefficients that change at iteration 7 and then revert.”

“I’m saying I don’t know what I’m saying. But look at the numbers you found. Pi. E. Phi. The three most irrational numbers in mathematics. A signature, maybe. Or a signature’s signature.”
