Ljg Paper River

Takes a research paper and recursively traces backward through the papers it critiques or improves (up to 5 layers deep), then looks forward at recent work building on it. The output is a chronological narrative that explains how the research problem evolved, focusing on what each paper saw as broken in the previous approach. The whole thing gets written as an org-mode file with ASCII diagrams showing the citation chain. Good for when you want to understand where an idea came from rather than just what the current paper says. The emphasis on problem evolution over paper summaries is the real differentiator here. Works best when you paste in an arxiv link or paper title and just want the full intellectual lineage.
