ABOUT AMSU
AMSU 是一个自动更新的信号研究与贸易展示站点。我们区分原始数据、注意力、商业代理、研究候选和未来结果，不把热度直接包装成销量、利润或投资建议。
AMSU 目前包含数据探索、开源信号影子研究、角色问答和贸易推广。各模块用途不同：数据用于观察，研究用于提出可验证命题，角色用于解释与质疑，贸易用于展示真实商品和收集采购线索。
公开数据通过定时任务采集、整理和更新；页面显示来源状态、更新时间或证据缺口。单一来源失败时应标记为不可用或部分可用，不把缺失值写成零。
部分中文简介由语言模型辅助翻译或整理。自动生成文字不替代原始来源，重要判断应返回证据链接或历史快照。
贸易商品、商家资料和询价记录与信号采集数据分开保存，不进入趋势排序或预测模型。商家提交内容需要人工审核；付费或推广内容会明确标识。没有可核验成交凭证时，价格使用“可询价”“参考价”或相应报价口径。
ABOUT AMSU
AMSU is an automatically updated signal-research and trade-directory website. It separates raw observations, attention, commerce proxies, research candidates and future outcomes. Popularity is never presented as sales, profit or investment advice.
AMSU currently provides data exploration, an open-source opportunity shadow study, role-based Q&A and a trade directory. Data supports observation; research states testable claims; roles explain and challenge; Trade displays reviewed products and collects procurement leads.
Scheduled jobs collect, normalize and refresh public data. Pages show source status, update times or evidence gaps. A failed source is marked unavailable or partial and is never converted into a false zero.
Some Chinese descriptions are translated or organized with language-model assistance. Generated text does not replace the original source, and important claims should remain traceable to evidence or historical snapshots.
Trade products, merchant submissions and inquiry activity are stored separately from opportunity research and never enter trend rankings or prediction models. Submissions require human review; paid or sponsored content is labelled. Without verifiable transaction evidence, prices are described as quote, reference price or the corresponding quotation type.
