A batch of errors. Also — the file got truncated?! The errors reference `digamma_natCast_eq` as unknown identifier at line 123 — meaning the file doesn't HAVE it — because my Edit appends were applied to the truncated file which ends at line 188... wait no. Let me check: the truncation left 188 lines ending at `exact harmonic_le_one_add_log N` — but that was the END of §2's helpers?? No — the truncated file ended at line 188 with `exact harmonic_le_one_add_log N` which is the end of `sum_one_div_le_one_add_log` — but the helpers `digamma_natCast_eq`, `summable_digamma_majorant`, `norm_digamma_term_le`, `sum_one_div_le_one_add_log` were AFTER §1's telescope... hold on. My original Write had: header, §1 (sum_range_one_div_sub, tsum_one_div_sub_telescope), §2 header, digamma_natCast_eq, summable_digamma_majorant, norm_digamma_term_le, sum_one_div_le_one_add_log, then the contaminated norm_digamma_le_of_two_le_re. Line 188 = end of sum_one_div_le_one_add_log ✓ so the truncated file HAS all the helpers ✓. But then the error "unknown identifier digamma_natCast_eq at 123" — line 123 in the CURRENT file — hmm my refactor edits: I edited the telescope (hasSum split at ~line 52-82) and appended the big §2 at the end. Wait — the error list has line 44 `simp made no progress`, line 60, 72 — those are in §1! And line 116 Int.toNat_mono, 122-123 in the integer case... but "unknown identifier digamma_natCast_eq at 123" — line 123 is within the INTEGER case of the main theorem — but the main theorem was appended at the END (line ~190+). Line 123 can't be in the appended part. CONFUSION. Let me look at the current file structure — maybe my Edit for the telescope refactor mismatched and corrupted the file (the hasSum edit replaced the doc+signature but the body...). Let me check what's at lines 40-130 now.
Multiple errors — possibly file corruption from the refactor edits. Checking the current structure.
