The h2 statement (from Ncount_le_of_interval_gen with a := -(2:ℝ)^(j+1)*X [=(−2^{j+1})·X] and b := -((2:ℝ)^j*X) [=−(2^j·X)]): the b−a+1 = (−(2^j·X)) − ((−2^{j+1})·X) + 1 — displays as `-(2 ^ j * X) - -2 ^ (j + 1) * X + 1` — a MIXTURE. This parse mess is error-prone. CLEANEST FIX: parenthesize ALL of them as -(2^j·X) and -(2^{j+1}·X) consistently: hW2's args, the Ncount call's a/b, hlen2's LHS, hlog2's max args. Let me do a global normalization: replace every `-(2 : ℝ) ^ (j + 1) * X` with `-((2 : ℝ) ^ (j + 1) * X)` and every `-(2 : ℝ) ^ j * X` with `-((2 : ℝ) ^ j * X)`. Then everything parses as −(2^{j+1}·X) / −(2^j·X) uniformly, and abs_neg works directly, and hlen2's pattern matches.","signature":""},{"type":"text","text":"Normalizing all unary-minus terms to the parenthesized form globally in this lemma."},{"type":"tool_use","id":"Bash_400","name":"Bash","input":{"command":"cd D:/Python/Quantum && python - << 'PYEOF'\np = 'research/lean/NguyenRH1/NguyenRH1/LiCircleBound.lean'\nsrc = open(p, encoding='utf-8').read()\n# Global parse normalization within the fiber_mult_count region: from the lemma header to end of file\nmarker = 'lemma fiber_mult_count'\nidx = src.index(marker)\nhead, tail = src[:idx], src[idx:]\ntail = tail.replace('-(2 : ℝ) ^ (j + 1) * X', '-((2 : ℝ) ^ (j + 1) * X)')\ntail = tail.replace('-(2 : ℝ) ^ j * X', '-((2 : ℝ) ^ j * X)')\n# fix the doubled parens that result: -((2:ℝ)^j * X) already had parens in some spots -> they become -((-((2...  no: the replace hits only the unparenthesized forms since parenthesized ones contain ') * X' before...
