Then my telescope refactor + the append of the main theorem — but the main theorem append matched on the END of the file (the tsum_one_div_sub_telescope lines)... NO — looking at the structure: the append's old_string was the tsum_one_div_sub_telescope theorem — which sits at line 82-85 — and the new_string was that theorem + the main theorem. So the main theorem got inserted at line 87, BEFORE the helpers (which were at 366+). So the helpers come after the main theorem ⟹ unknown identifiers. AND the file lost the `end NguyenRH1 / end` markers? The structure shows the helpers at the end — are the end markers there? Let me check the tail. Also the \"unexpected token ')'\" at 210:79.\n\nFix plan: move the main theorem to the END (after the helpers). Simplest: read the whole file, reorder. Since the helpers are at the end (lines 366–470ish) and the main theorem is at 87–365, I need to swap the two blocks. Let me do it with bash: extract lines, reorder. Actually easier: delete the main-theorem block from its current position and re-append at the end.\n\nLet me look at the boundaries: main theorem spans 87 (doc) to ~365 (before line 366's /-! ## 2 header). The helpers section starts at 366 with the \"/-! ## 2. The right-half-plane bound (B) -/\" header.
