Append-only frontier research synchronization for Obsidian technical documents, with interactive, scheduled, and review modes. Use when the user asks to update, create, maintain, refresh, schedule, automate, or periodically run a "前沿信息同步"/frontier update section in one or more Markdown technical notes. In interactive mode, propose 3-10 priority information sources and ask the user which to keep/add/remove before writing. In scheduled mode, use existing confirmed sources and append dated updates without deleting history. In review mode, collect and report candidate updates without editing files.
