Show HN: ZTHR – what replaces code review when AI agents write all the code

ZTHR is a pattern language for software built by AI, based on two principles: Symmetric Zero Trust, where no author, reviewer, model, operator or report gains authority by asserting success, and the Fixture Inversion, where quality comes from the environment rather than the author's skill. The post links a reference app built entirely by agents under ZTHR, including live app and admin demos, an evidence factory of gates and tests, full source on GitHub, and a discussion forum. It is published as Version 1.0 via Zenodo (doi.org/10.5281/zenodo.23826734).
