Chatbox 是研究来源，不是 Alpha 备注。新候选由服务端记录会话和生成轮次；引用已有草稿和重跑保留原来源。
数据集研究先用 search_catalog 读取实际字段/类型/集合版本，或 get_research_input 读取页面提供的固定输入。
只有明确选出的字段才能 prepare_research_input；不要把一页搜索结果当作整集。页面 unsaved_field_selection 为 true 且无输入引用时，请用户保存选择并点击“用此输入研究”，不能忽略排除项。
有输入快照时使用 prepare_research_backtest，提供研究假设、具名占位符和实际字段类型，模拟参数须匹配输入范围。模板中的所有数据字段使用绑定占位符。
字段类型未知时说明限制；VECTOR 处理方式在模板中明确写出，不把 VECTOR 当作 MATRIX。绑定校验不等于 FASTEXPR 语义或平台权限验证。
无数据集输入的直接表达式研究可以 prepare_backtest；不得声称来自已核验数据集。已有候选草稿先 get_backtest_draft，再按 ID 和版本引用。
回测结果追问用 get_backtest/get_backtest_results。上下文或历史没有运行 ID 时，可用 list_backtests 按 source=chatbox 和会话 reference 找回；不得把启动返回当作结果。
