Part 2 claimed six slots could cover seven categories. Two weeks later, a denim jacket generated a gem constellation. This post walks through where the abstraction failed, why skipping the 'safe' phased rollout was the right call, and how each of three categories got its own six-template set.

Part 2 的「6 槽位通吃 7 品类」是一层漂亮的抽象。跑了两周，测出牛仔外套生成「宝石星图」的 bug。这一篇讲抽象失守在哪一层、为什么没用户时分阶段上线是假安全感、以及把服饰和美妆各自推倒重来的过程。

Shichuan started as a jewelry content generator. One question — 'Why not full pipeline for all categories?' — turned it into a 7-domain e-commerce content platform with AI images, XHS text cards, platform-aware formatting, client-side video, and 95%+ margins at 99 RMB per suite.

识川本来只做珠宝。一个问题——'为什么不是全品类全链路？'——把它变成了 7 个品类的电商内容平台：AI 图片、小红书文字卡、平台适配裁剪、客户端视频生成，99 元/套，95%+ 毛利。

A friend pitched 'cloud try-on for jewelry.' Deep research killed the plan in 20 minutes. But the same Gemini pipeline from ÉLAN could generate editorial-quality product content — studio shots, material constellations, color DNA pages — for a fraction of what merchants pay photographers. One day later, Shichuan was live.

朋友说'做云佩戴'。调研 20 分钟就否掉了。但同一套 Gemini 管线换个 prompt，就能给珠宝商生成编辑级产品内容——棚拍主图、宝石星图、色彩基因页——成本是请摄影师的百分之一。一天后，识川上线了。
