痛点：工程师在准备系统设计面试时缺乏互动式的高层设计（HLD）学习工具，传统资料枯燥且脱离实际决策场景。

目标用户：准备系统设计面试的软件工程师、技术负责人（CTO/架构师）以及想提升HLD能力的开发者。

证据：I realized my High-Level Design (HLD) skills weren't as strong as I thought. So I decided to build something to help me learn, and hopefully help others too.

变现：基础免费开源，高级关卡/场景包付费，企业内训授权，或认证证书收费。

MVP：两周内做出基于决策树的3-5个经典系统设计面试场景游戏，玩家作为CTO做架构选择并看到后果，完成后生成可分享证书。

竞品：Grokking System Design、Educative System Design、System Design Primer

摘要：作者因公司倒闭重新面试，发现自己HLD技能不足，于是开发了免费开源的决策式系统设计游戏ScaleLog，玩家扮演CTO处理工程事故并学习HLD，完成可得证书。目前完全免费、无需登录，作者请求技术准确性反馈，但未体现任何付费意愿或收入数据。
