## Summary

The behind-the-scenes rebuild of Lumina from Gen-1 to an enterprise-grade Gen-2.

## Overview

This is not a product announcement. It is a build log with the workings left in — what I decided, what I got wrong, which models I used at which stage, and the workflow that made a one-month rebuild of a production platform possible at all. If you are building with AI coding agents, the second half of this article is the part worth your time. If you are evaluating AI for your own company, the first half is.
