PHASE 1 / STRATEGY RESEARCH LIBRARY
This is the evidence layer. It includes only the strategy pages whose question, baseline, evidence chain, and current decision are clear enough for public reading.
这里是证据层，只放已经讲清楚研究问题、baseline、证据链和当前判断的策略页。
Before this page. Read 02 / Strategy Triage - From Intuition to Baseline first. It explains which intuitive ideas stayed alive after testing and which ones were archived.
先读上一层。 先读 02 / Strategy Triage - From Intuition to Baseline。那一页说明哪些直觉经得起测试，哪些需要归档。
Page rule. A strategy gets a full page only after it can answer five questions: why it exists, what it tests, which baseline it must beat, what evidence supports it, and what would falsify it.
进入这一层的标准。 一条策略只有先回答五个问题，才值得单独成页：为什么研究它、它验证什么、要战胜哪个 baseline、证据在哪里、什么结果会证伪它。
03.01 / Spot Long-Only Trend Sleeve
Why keep the system as simple spot long-only after testing the short-leg intuition? How does it hold up under baseline comparison, attribution, robustness, cost, and execution checks?
做空腿验证失败后，为什么最后保留简单的现货做多？它在 baseline 对比、归因、稳健性、成本和执行测试下是否仍然站得住？
03.02 / Smart DCA / Mayer Accumulation
Is it better than fixed DCA? Does it make the accumulation process more disciplined and easier to live with for a real individual investor?
它是否比固定定投更好？对真实个人投资者来说，它能不能让积累过程更有纪律，也更容易坚持？
