 <!-- 每条独立一行追加到本段末尾，无需分类标题，合并时冲突最小 -->
 
 - [修复] 大盘复盘链路接入 `REPORT_LANGUAGE`：`REPORT_LANGUAGE=en` 时，A 股/合并复盘的 Prompt、章节标题、模板兜底文案与通知包装标题统一改为英文，避免出现英文正文外包中文标题的问题。
+- [修复] `EfinanceFetcher.get_main_indices()` 对东方财富指数实时行情的开盘价映射改为兼容 `今开 -> 开盘 -> open`，修复部分 `efinance` 版本下指数开盘价被读成缺失值的问题（fixes #1043）
 - [修复] `AGENT_MAX_STEPS` 在 orchestrator 多 Agent 模式下统一明确为“默认作为各子 Agent 的步数上限而非硬覆盖；TechnicalAgent 等高默认值 Agent 会被封顶、低默认值 Agent 保持原值；当用户主动调高（>10）时，再统一覆盖所有子 Agent 采用全局值”，同时修复用户设置 12 但 TechnicalAgent 仍以默认 6 步运行并报 "Agent exceeded max steps" 的问题（fixes #1026）
 - [修复] Specialist（Skill）Agent 失败不再中断整个分析管线，改为与 intel/risk 相同的优雅降级策略
 - [改进] Agent 超步数错误信息增加 AGENT_MAX_STEPS 调整提示，帮助用户自助排查
