Ljg Book

Reconstructs a book into x → f → f(x): the problem it addresses, the author's central answer, and how that answer changes your judgment or action. You give it a book title, PDF, or excerpt (or just ask 拆书), and it generates an org-mode note with three summary lines up top, then expands the logical chain in four fixed sections. It scans for the hardest concept to visualize and picks the lowest-cost representation, whether that's an ASCII diagram, a table, or just prose. Not for chapter summaries or framework audits. The completion checklist is rigorous: it verifies the three lines actually connect as a chain, that f explains mechanism rather than listing terms, and that f(x) specifies what concretely shifts in understanding or action.
