Only the final nlinarith (line 1700) fails now. Everything else elaborated. I need to see why the final assembly is insufficient. Let me trace the logical chain once more, VERY carefully, checking every hypothesis type against what the chain needs. Goal (after rw [hBn]): `|Sf ↑n| ≤ 4·FAlt(√n+1) + 4(√n+1)·X(√n+1) + 40·1.3352 + 2(e⁴+1)·7·Hhat(√n+1) + 2·DLR + IIMaj + 1` where X(t) = (2/3)·Z2hat t + 10.5·log(t+2)+48. Facts in the only-list: - hsf : |Sf n| ≤ ‖RectInt'‖ + ‖Σ‖ - hnormRect : ‖RectInt'‖ ≤ (1/2π)·(‖H−‖ + ‖H+‖ + ‖Vr‖ + ‖Vl‖) - hVl' : (1/2π)·‖Vl‖ ≤ (1/2π)·(4T·X(T) + 40·1.3352) - hVr' : (1/2π)·‖Vr‖ ≤ (1/2π)·(e13·IIMaj) - hH' : (1/2π)·(‖H+‖+‖H−‖) ≤ (1/2π)·(2·((e⁴+1)·(NI+5.5R)+DLR)) - hbridge : ‖Σ‖ ≤ 4·FAlt T + 1 - hIIMajAbs : (1/2π)·(e13·IIMaj) ≤ IIMaj - hHhatAbs : (1/2π)·(2(e⁴+1)·7·Hhat T) ≤ 2(e⁴+1)·7·Hhat T - hDLRAbs : (1/2π)·(2·DLR) ≤ 2·DLR - hXAbs : (1/2π)·(4T·X+40M0) ≤ 4T·X+40M0 - hPinchAbs : ((1/2π)·2(e⁴+1))·(NI+5.5R) ≤ ((1/2π)·2(e⁴+1))·(7·Hhat T) - hFAlt : FAlt T ≤ FAlt(√n+1) - hX : 4T·X(T) ≤ 4(√n+1)·X(√n+1) - hHhat : Hhat T ≤ Hhat(√n+1) - hIIMaj0, hDLR0, hHhat0, hX0 (nonnegs) The chain: |Sf| ≤ ‖RectInt'‖ + ‖Σ‖ ≤ (1/2π)(‖H−‖+‖H+‖+‖Vr‖+‖Vl‖) + (4F+1) [hsf, hnormRect, hbridge] ≤ (1/2π)(2((e⁴+1)(NI+5.5R)+DLR) + e13·IIMaj + (4TX+40M0)) + (4F+1) [hH', hVr', hVl'] The (1/2π)(‖H−‖+‖H+‖+‖Vr‖+‖Vl‖) distributes: (1/2π)‖H−‖ + (1/2π)‖H+‖ + (1/2π)‖Vr‖ + (1/2π)‖Vl‖. hH' bounds (1/2π)(‖H+‖+‖H−‖) — the DISTRIBUTED form is (1/2π)‖H+‖ + (1/2π)‖H−‖ — linarith's ring_nf connects (1/2π)·(A+B) ↔ (1/2π)A + (1/2π)B ✓ should be fine. = (1/2π)·2(e⁴+1)(NI+5.5R) + (1/2π)·2DLR + (1/2π)(e13·IIMaj) + (1/2π)(4TX+40M0) + 4F+1 hPinchAbs's LHS: ((1/2π)·2(e⁴+1))·(NI+5.5R) — and the distributed term from hH' is (1/2π)·(2·((e⁴+1)·(NI+5.5R)+DLR)) = (1/2π)·(2(e⁴+1)(NI+5.5R)) + (1/2π)·(2·DLR) — hPinchAbs's LHS form ((1/2π)·2(e⁴+1))·(NI+5.5R) vs (1/2π)·(2(e⁴+1)(NI+5.5R)) — ring_nf normalizes ✓ fine. ≤ (1/2π)·2(e⁴+1)·7·Hhat T + 2·DLR + IIMaj + (4TX+40M0) + 4F+1 [hPinchAbs, hDLRAbs, hIIMajAbs, hXAbs] ≤ 2(e⁴+1)·7·Hhat T + 2·DLR + IIMaj + 4TX+40M0 + 4F+1 [hHhatAbs] ≤ 2(e⁴+1)·7·Hhat(√n+1) + 2·DLR + IIMaj + 4(√n+1)·X(√n+1) + 40M0 + 4·FAlt(√n+1) + 1 [hHhat, hX, hFAlt] = Bn ✓ This looks airtight... — unless one of the haves' STATEMENTS doesn't match what I think. Possible mismatches: (i) hH's actual type (hIntegral_Jlag_full_two_sides): `‖H(+)‖ + ‖H(−)‖ ≤ 2·((e⁴+1)·(2·Z2hat T·log(148.5·C0hat(√n+2)) + (3−−5/2)·(10.5·log(T+2)+48)) + DogLegRight ↑n)` ✓ — and hH' = mul_le_mul_of_nonneg_left hH (0 ≤ 1/2π) : (1/2π)·(‖H+‖+‖H−‖) ≤ (1/2π)·(2·(...)) ✓. (ii) hVr's type: ‖VIntegral (Jlag n) (2·√n) (−T) T‖ ≤ e13·IIMaj ✓. (iii) hVl's type: ‖VIntegral (Jlag n) (−5/2) (−T) T‖ ≤ 4T·((2/3)·Z2hat T + 10.5·log(T+2)+48) + 40·1.3352 ✓. (iv) hnormRect's RHS: (1/2π)·(‖H−‖ + ‖H+‖ + ‖Vr‖ + ‖Vl‖) ✓. Hmm — the nlinarith might be failing because the products (1/2π)·X are treated as atoms (1/2π) times atom X — the distribution/normalization should hold... — OR — the issue: nlinarith's ring_nf might be UNABLE to normalize terms containing `Real.exp (1/3)`, `Real.pi`, divisions — the divisions: 1/(2·π) — ring_nf handles division by turning into inverse-power?? — ring_nf on `1 / (2 * Real.pi)` — normalizes to `(2*π)⁻¹` — and products like `(1/(2π))·e13` → `(2π)⁻¹·e13` ✓ fine — the ABSORPTION facts (hIIMajAbs etc.) have already-factored forms ✓. Hmm — what about `Hhat T` vs `Hhat (√n+1)` — different atoms ✓ hHhat relates them ✓. `Z2hat T` vs `Z2hat(√n+1)` ✓ via hX. `FAlt T` vs `FAlt(√n+1)` ✓ via hFAlt. `C0hat(√n+2)` inside log148.5 — that atom appears in hpinchAbs's NI term — and nowhere else — it just gets bounded via hPinchAbs ✓. Wait — actually — hmm — let me recheck the hHhatAbs statement: `(1/(2π))·(2·(e⁴+1)·(7·Hhat T)) ≤ 2·(e⁴+1)·(7·Hhat T)` ✓. And hPinchAbs : ((1/(2π))·2(e⁴+1))·(NI+5.5R) ≤ ((1/(2π))·2(e⁴+1))·(7·Hhat T) — so (1/2π)·2(e⁴+1)·(NI+5.5R) ≤ (1/2π)·2(e⁴+1)·7·Hhat T — chain to hHhatAbs ✓. Hmm — everything checks. So why does nlinarith fail? Possibilities: (a) A statement form mismatch — e.g., hnormRect's distribution: (1/2π)·(‖H−‖ + ‖H+‖ + ‖Vr‖ + ‖Vl‖) — the hH' needs (1/2π)·‖H+‖ + (1/2π)·‖H−‖ — the DISTRIBUTION of (1/2π)·(‖H−‖+‖H+‖+‖Vr‖+‖Vl‖) into 4 scaled terms — ring_nf does this ✓. (b) nlinarith's preprocessing TIMES OUT silently and reports failure? — it said "linarith failed to find a contradiction" — that's the linarith CORE failing (not timeout) — meaning after preprocessing, the linear problem is UNSOLVABLE with the given facts — a genuine LOGICAL GAP or atom mismatch. Let me look for an atom mismatch: the NI term: hH's inner: `2 * Z2hat T * Real.log (148.5 * C0hat (√↑n + 2)) + (3 - -5/2) * (10.5 * Real.log (T + 2) + 48)`. hpinch's LHS: `2 * Z2hat T * Real.log (148.5 * C0hat (√↑n + 2)) + (3 - -5/2) * (10.5 * Real.log (T + 2) + 48)` — wait — hpinch's statement: `2 * Z2hat T * Real.log (148.5 * C0hat (√n+2)) + (3 - -5/2) * (10.5 * Real.log (T + 2) + 48) ≤ 7 * Hhat T` ✓ SAME. And hPinchAbs = mul_le_mul_of_nonneg_left hpinch ... : ((1/2π)·2(e⁴+1))·(2·Z2hat·log148.5 + (3−−5/2)·R) ≤ ... ✓ consistent. Hmm — and hXAbs : (1/(2π))·(4T·X(T) + 40·1.3352) ≤ 4T·X(T) + 40·1.3352 ✓ and hVl' : (1/(2π))·‖Vl‖ ≤ (1/(2π))·(4T·X(T)+40·1.3352) ✓ chain ✓. WAIT — I see a possible issue: hnormRect's bound: (1/2π)·(‖H−‖ + ‖H+‖ + ‖Vr‖ + ‖Vl‖) — but hVr is about ‖VIntegral (Jlag n) (2·√n) (−T) T‖ and hVl about ‖VIntegral (Jlag n) (−5/2) (−T) T‖ ✓ match htri's forms ✓. Hmm — let me look at the ACTUAL goal once more. After `rw [hBn]` — the goal is `|Sf ↑n| ≤ (Bn-expanded)`. And hsf : |Sf n| ≤ ... — `Sf n` with n : ℕ — and the goal's `Sf ↑n`?? — Sf (n : ℕ) : ℝ — `Sf n` — the goal after intro n hn hN1: `|Sf n| ≤ Bn FAlt ↑n` — Sf n with n : ℕ ✓ — and hsf : |Sf n| ≤ ... ✓ same ✓. Hmm — one more: the hBn expansion — is it CORRECT? Bn's def: `let T := Real.sqrt n + 1; 4 * F T + 4 * T * ((2/3) * Z2hat T + 10.5 * Real.log (T + 2) + 48) + 40 * 1.3352 + 2 * (Real.exp 4 + 1) * (7 * Hhat T) + 2 * DogLegRight n + IIMaj n + 1` — my hBn's RHS: `4 * FAlt (√n+1) + 4*(√n+1)*((2/3)*Z2hat(√n+1) + 10.5*Real.log(√n+1+2) + 48) + 40*1.3352 + 2*(e⁴+1)*(7*Hhat(√n+1)) + 2*DogLegRight ↑n + IIMaj ↑n + 1` — with `Real.log (Real.sqrt (n:ℝ) + 1 + 2)` — Bn's def has `Real.log (T + 2)` with T := √n+1 — so log((√n+1) + 2) = log(√n + 1 + 2) ✓ same ✓. And the hBn rfl proved ✓ (no error at 1651!) ✓. Hmm — so the final goal IS the expanded Bn ✓. Then why does nlinarith fail?? — let me think about what could be UNSOLVABLE. Everything's linear modulo the atom products. Hmm — WAIT — one potential issue: hPinchAbs's RHS: ((1/2π)·2(e⁴+1))·(7·Hhat T) and hHhatAbs's LHS: (1/(2π))·(2·(e⁴+1)·(7·Hhat T)) — ring_nf should normalize both to the same monomial — (2π)⁻¹·2·(e⁴+1)·7·Hhat ✓ same ✓. Hmm — hold on — maybe the problem is the hH' distribution interacts with hPinchAbs: the hH' bound's RHS is (1/(2π))·(2·((e⁴+1)·(NI+5.5R)+DLR)) — distributing: (1/(2π))·(2(e⁴+1)(NI+5.5R) + 2·DLR) = (1/(2π))·(2(e⁴+1)(NI+5.5R)) + (1/(2π))·(2·DLR) — hPinchAbs's LHS: ((1/(2π))·2(e⁴+1))·(NI+5.5R) — normalized: 2·(2π)⁻¹·(e⁴+1)·(NI+5.5R)?? — hmm — (1/(2π))·(2(e⁴+1)(NI+5.5R)) vs ((1/(2π))·2(e⁴+1))·(NI+5.5R) — SAME monomial ✓. Everything normalizes identically. So the failure must be a MISSING link or an atom I overlooked. Let me actually TEST the assembly logic manually: maybe nlinarith can't handle the DISTRIBUTION of (1/(2π)) over the 4-term sum in hnormRect AND the subsequent bounding — it should. Hmm — wait — maybe the issue is `Sf n` vs the perimeter... — no. Let me try a different diagnosis: is it possible that nlinarith only [list] FAILS because one of the listed haves has a TYPE with a metavariable or is otherwise malformed (sorry'd from an earlier error that got fixed but the sorry persists)? — the earlier errors at hPinchAbs/convert — those got fixed — the current run has no other errors — so all haves are clean. Hmm — OR — the `rw [hBn]` happened and the goal is exactly Bn-expanded ✓. Let me look at the failing goal state directly — the error's goal display was truncated in my grep. Let me get the full goal at 1700.
Only the final assembly fails now. Let me see the full goal state at line 1700.

Let me actually TEST the assembly logic manually: maybe nlinarith can't handle the DISTRIBUTION of (1/(2π)) over the 4-term sum in hnormRect AND the subsequent bounding — it should.\n\nHmm — wait — maybe the issue is `Sf n` vs the perimeter... — no.\n\nLet me try a different diagnosis: is it possible that nlinarith only [list] FAILS because one of the listed haves has a TYPE with a metavariable or is otherwise malformed (sorry'd from an earlier error that got fixed but the sorry persists)? — the earlier errors at hPinchAbs/convert — those got fixed — the current run has no other errors — so all haves are clean.\n\nHmm — OR — the `rw [hBn]` happened and the goal is exactly Bn-expanded ✓.\n\nLet me look at the failing goal state directly — the error's goal display was truncated in my grep.
