01 · The Product产品

Not a demo. A shipping product, built solo, with an agent fleet. 不是 demo，是一个人带着 agent 舰队交付的真产品。

The schedule you watched assemble above is my constraint-solver engine working on real catalog data. It plans what students spend days agonizing over, and it never returns an empty answer. 开屏那张自己拼好的课表，就是我的约束求解引擎在真实课程数据上运行。学生纠结几天的选课，它一秒排完，而且永远不会甩给你一个空结果。

4,395

Constraint Engine约束求解引擎

OR-Tools CP-SAT over a normalized catalog, 4,395 courses linked to grade history. When sections fill up it degrades honestly instead of failing. OR-Tools CP-SAT 跑在规范化课程库上，4,395 门课打通历史成绩数据。选不上时诚实降级，绝不摆烂报错。

×32

Built with Agentsagent 造出来的

A 32-agent adversarial review attacked the engine before launch: 20 confirmed bugs found and fixed. The build holds 826 checks green. 上线前用 32 个 agent 对抗审查围攻引擎，确认并修掉 20 个 bug；构建保持 826 项检查全绿。

02 · The Method方法

One person, operating like a team. 一个人，跑出一支团队的产能。

AI is my leverage, not my autopilot. I design the system, agents do the labor, adversarial review keeps everyone honest. AI 是杠杆，不是自动驾驶。我设计系统，agent 出苦力，对抗审查让所有产出过得了质检。

32 agents · 51 findings→ 20 confirmed & fixed

AIOS, my personal AI operating systemAIOS：我的个人 AI 操作系统

Daily briefs, email triage, project memory across everything I do. It distills my corrections into new operating rules every week, human-reviewed. 日报、邮件分诊、全项目记忆图谱。每周把我的纠正蒸馏成新规则，人工审核后生效，系统自己长大。

Adversarial by default默认对抗验证

Every important claim gets skeptic agents hired to refute it. What survives, ships. What doesn't, never reaches the user. 重要结论一律雇「杠精 agent」专职反驳。驳不倒的才上线，驳倒的永远到不了用户面前。

Ship, not demo交付成品，不交付演示

Checks, honest degradation, bilingual UI, real data. The bar is "a stranger can use it," not "it worked once on my machine." 检查全绿、诚实降级、双语界面、真实数据。标准是「陌生人能用」，不是「在我电脑上跑通过一次」。

AI application-layer thesisAI 应用层投资 thesis

One question: whose budgets does AI eat, and who gets re-rated? Contested names (Adobe, Unity, Duolingo), validated on middle indicators, never on price. 只问一个问题：AI 在吃谁的预算、谁会被重估？盯争议股（Adobe、Unity、Duolingo），用中间指标验证，不看股价自我说服。
