1. **1458: identity ring failed** — unsolved goals: the ring normalization got MOST of the way but the remaining goal shows `√n * Real.log (3 + √n)` — i.e., the LHS (marginTilde) has log(T+2) with T = √n+1 → T+2 = √n+3 = 3+√n ✓ and MY pieces wrote `Real.log (√n+1+2)` — after ring normalization √n+1+2 → 3+√n on the LEFT but the RIGHT side (my expanded) has... the remaining goal shows mismatch: LEFT normalized to `Real.log (3 + √n)` terms while RHS pieces still have `Real.log (√n + 1 + 2)`?? ring should normalize both to the same atom... The atoms DIFFER: Real.log (3+√n) vs Real.log (√n+1+2) — ring normalizes the ARGUMENTS to the same polynomial 3+√n?? It should — arguments are ring expressions: √n+1+2 normalizes to 3+√n — but as ATOMS for ring, `Real.log (3+√n)` and `Real.log (√n+1+2)` are DIFFERENT atoms unless ring normalizes inside the log argument — ring DOES normalize arguments of function applications when treating them as atoms?? NO — ring treats log X as an atom keyed by the SYNTACTIC X (after basic normalization?). The remaining goal cut off — the mismatch is visible: LHS has Real.log (3 + √n), so the DEF's log(T+2) with T = √n+1 elaborates as Real.log (√n + 1 + 2) which ring normalized to Real.log (3 + √n)?? And my pieces wrote Real.log (Real.sqrt m + 1 + 2) — same thing! Both should normalize identically... unless the DEF's is `Real.log (T + 2)` with T := √n+1 → `Real.log (√n + 1 + 2)` and mine `Real.log (√m + 1 + 2)` — SAME. Then why remaining goals? Look: the goal shows `-350903/375 + ...` — a giant polynomial difference NOT zero — so the WEIGHTS are wrong somewhere! -350903/375 = -935.74... — my mK or weights miscalculated. The displayed terms: `√n * (-2996/15)` — coefficient of √n: -2996/15 = -199.73̄ ✓ matches mIdb's −((8/3)*2.9+192) = −(7.73̄+192) = −199.73̄ ✓. `√n*log(3+√n)*(−16183/375)`: −16183/375 = −43.154̄ ✓ TL1 ✓. `√n*log(log(3+√n))*(−886/375)`: −886/375 = −2.362̄ ✓ TL2 ✓. So those match — the remaining mismatch is in OTHER terms (cut off). The constant -350903/375 = -935.741̄. My mK: −4 − 40·1.3352 − 2(e⁴+1)(7(3·2.9²+48)+3.3) − 1 + 1. Hmm — the discrepancy likely in the L1/L2/L1sq weights or the constant. Since the goal is cut, I can't see. Let me recompute carefully by hand what the DEF gives:
B̃ = 2F + 4T·G + 40·1.3352 + 2(e⁴+1)(7H + 3.3) + IIMaj + 1,
G = (2/3)C + 10.5 L1 + 48, C = 0.433 L1 + 0.886 L2 + 2.9,
H = 3C² + 10.5 L1 + 48.
4T·G = 4T·[(2/3)(0.433 L1 + 0.886 L2 + 2.9) + 10.5 L1 + 48]
= T·[(8/3)(0.433) L1 + (8/3)(0.886) L2 + (8/3)(2.9) + 42 L1 + 192]
= T·L1·[(8/3)(0.433) + 42] + T·L2·(8/3)(0.886) + T·[(8/3)(2.9) + 192] ✓ (matches my w: 43.154̄, 2.362̄, 199.73̄ ✓).
2(e⁴+1)(7H+3.3) = (e⁴+1)·[14H + 6.6] = (e⁴+1)·[14(3C² + 10.5 L1 + 48) + 6.6] = (e⁴+1)·[42 C² + 147 L1 + 672 + 6.6] = (e⁴+1)·[42C² + 147 L1 + 678.6].
42C² = 42(0.433 L1 + 0.886 L2 + 2.9)² = 42·[0.187489 L1² + 0.784996 L2² + 8.41 + 0.767276 L1L2 + 2.5114 L1 + 5.1388 L2]
= 7.874538 L1² + 32.969832 L2² + 353.22 + 32.225592 L1L2 + 105.4788 L1 + 215.8296 L2.
So the (e⁴+1) bracket total: L1²: 7.874538; L2²: 32.969832; L1L2: 32.225592; L1: 105.4788 + 147 = 252.4788; L2: 215.8296; const: 353.22 + 678.6 = 1031.82.
My weights: mL1sqb: 42*0.433^2 = 42*0.187489 = 7.874538 ✓; mL1L2b: 42*(2*0.433*0.886) = 42*0.767276 = 32.225592 ✓; mL2sqb: 42*0.886^2 = 42*0.784996 = 32.969832 ✓; mL1b: (42*(2*0.433*2.9) + 147) = 105.4788+147 = 252.4788 ✓; mL2b: 42*(2*0.886*2.9) = 42*5.1388 = 215.8296 ✓.
Constants: mK = −4 − 40·1.3352 − 1031.82(e⁴+1) − 1 + 1 = −4 − 53.408 − 1031.82(e⁴+1). In my mK def: `-4 - 40*1.3352 - 2*(Real.exp 4 + 1)*(7*(3*2.9^2 + 48) + 3.3) - 1 + 1` — 7*(3*2.9²+48)+3.3 = 7*(25.23+48)+3.3 = 7*73.23+3.3 = 512.61+3.3 = 515.91; ×2(e⁴+1) = 1031.82(e⁴+1) ✓ matches.
So where's the mismatch? The displayed constant −350903/375: −350903/375 = −935.7413̄. Hmm — that doesn't decompose obviously. Wait — the ring "unsolved goals" display shows the FULL difference: −350903/375 + n*log n*(1/2) + n*lagariasC1 + nγ(−1/2) + √n*(−2996/15) + ... — this looks like it's the ENTIRE difference expression — with n*log n*(1/2) POSITIVE — but marginTilde HAS +½n log n and my expanded ALSO has +½n log n — they should CANCEL. The difference has +½n log n — meaning my expanded's mS piece did NOT unfold/match! The `fun m => (1/2)*m*Real.log m + c*m − 4` inside marginExpanded — I unfold marginExpanded but NOT the anonymous S-lambda (it's not a def) ✓ it's a literal lambda ✓ should apply... The displayed `n * lagariasC1 + n * γ * (−1/2)` — the c = lagariasC1 − γ/2 piece ✓ present on ONE side... The difference retaining +½n log n means one side has it twice or the other side lacks it — the LHS marginTilde has (1/2)*n*log n ✓ RHS has it in mS ✓ — unless the LHS's structure: marginTilde = S − B̃ + 1 where S = ((1/2)*n*log n + cn − 4) — ✓...
Hmm wait — maybe the issue: `unfold marginTilde` — marginTilde has a `let T := ...` — after unfold the goal keeps the let? `unfold` might not zeta-reduce the let! If the let remains, ring sees `let T := √n+1; body` — can't normalize. Actually Lean 4 `unfold` of a def with let gives the let-expression; ring might not zeta-expand. Add `show` with the zeta-reduced form or `simp only [marginTilde]`? Or `dsimp only` after unfold to beta/zeta-reduce. Let me add `dsimp only` after the unfold list — but dsimp only with no lemmas does beta/eta/zeta ✓.
Actually the visible −350903/375 constant — with both sides' constants included (ring showing nonzero constant) — if the let blocks one side's B̃ expansion... plausible.
Fix: after unfold, add `ring_nf`?? no. Use: `simp only [marginTilde, marginExpanded, mFblock, ...]`? simp only with def names unfolds + beta-reduces ✓ better. Or: unfold ...; dsimp only; ring. Try dsimp only.
2. **1467: contDiffOn_mS type mismatch** — my term's structure wrong: ((const.mul (id.mul (id.log))).add (const.mul id)).sub const — the function: ((1/2)*(m*log m) + c*m) − 4 — goal: fun m => (1/2)*m*Real.log m + c*m − 4 — the (1/2)*m*Real.log m parses ((1/2)*m)*(log m) vs my (1/2)*(m*log m) — mismatch! Fix: (contDiffOn_const.mul contDiffOn_id).mul hlog : fun m => ((1/2)*m)*(log m) ✓:
(((contDiffOn_const.mul contDiffOn_id).mul (contDiffOn_id.log ...)).add (contDiffOn_const.mul contDiffOn_id)).sub contDiffOn_const
3. **1515: isDefEq timeout + 1518:61 unexpected token ')'** — in contDiffOn_mIIM: `apply contDiffOn_const.mul` — the `apply` left the function-matching goal... and there's a paren error at 1518:61 — my nested parens in contDiffOn_mIIM are unbalanced: `(psiTilde_contDiff.contDiffOn).comp (contDiffOn_id.sqrt (fun x hx => by ...)) (Set.mapsTo_univ _ _)` — count parens... the `(fun x hx => by have h : 20 < x := hx; exact ne_of_gt (by linarith : (0:ℝ) < x))` — the by-block with `;` sequencing — in term mode `by t1; t2` needs newlines or `·`. The `;` might have ended the by block early leaving stray `)`. Restructure contDiffOn_mIIM with have's instead of inline term.
Fix all three.
Three issues: zeta-reduction in the identity (the `let` in marginTilde), mS associativity, and mIIM's term structure. Fixing.
