thinking (4758 chars)
Now I understand the structure. The key definitions to change for the c = 1.5 redo:
1. **Bn** (2431): `T := √n + 1` → `T := 1.5√n + 1`; `(Real.exp 4 + 1)` → kernel charge e^{16/9}+1; `3.3` → R(1.5) = 5.94; `IIMaj n` → IIMaj_c (×1.5 length).
2. **marginTilde** (766): same changes in lockstep.
3. **marginExpanded blocks** (1815–1832): the block constants:
- mFblock: −4·F(√m+1) → −4·F(1.5√m+1)
- mTL1b: coefficient −((8/3)·0.6 + 42) multiplying (t·log(t+2))(√m+1) → the I_III term is 4T[(2/3)Z2 + 10.5 log(T+2) + 48] = 4T[(2/3)(0.6 log(T+2) + 0.886 loglog(T+2) + 2.7) + 10.5 log(T+2) + 48] = T·log(T+2)·(4·(0.4+10.5)) + T·loglog(T+2)·(4·(2/3)·0.886) + T·(4·(1.8+48)) = T·log(T+2)·43.6 + T·loglog·2.3627 + T·199.2. The blocks have coefficients (8/3)·0.6 + 42 = 1.6+42 = 43.6 ✓, (8/3)·0.886 = 2.3627 ✓, (8/3)·2.7+192 = 7.2+192 = 199.2 ✓. These constants don't change with c — what changes is the INNER function: (√m+1) → (1.5√m+1). And the horizontal kernel factor (e⁴+1) → (e^{16/9}+1) in mL1sqb/mL1L2b/mL2sqb/mL1b/mL2b and mK; and the 3.3 → 5.94 in mK; and the inner function in the log blocks (√m+1) → (1.5√m+1); mIIM: IIMaj → IIMaj_c.
Wait — the horizontal piece in Bn: 2(e⁴+1)(7Ĥ(T)+3.3), Ĥ(T) = 3Ĉ₀² + 10.5 log(T+2)+48, Ĉ₀ = 0.433 log + 0.886 loglog + 2.9. Expanding 2(e⁴+1)·7·3·Ĉ₀² = 42(e⁴+1)Ĉ₀²: the blocks mL1sqb (log² coefficient 42·0.433²·(e⁴+1)), mL1L2b (42·2·0.433·0.886·(e⁴+1)), mL2sqb (42·0.886²(e⁴+1)), mL1b ((42·2·0.433·2.9 + 147)(e⁴+1)·log — wait the 147 = 2(e⁴+1)·7·10.5 = 147(e⁴+1)? 2·7·10.5 = 147 ✓ so the log(T+2) coefficient is (42·(2·0.433·2.9) + 147)·(e⁴+1) ✓), mL2b (42·2·0.886·2.9·(e⁴+1)·loglog). And mK: −40·1.3352 − 2(e⁴+1)(7(3·2.9²+48)+3.3) − 1 + 1.
So for the redo: replace (Real.exp 4 + 1) → (Real.exp (16/9) + 1) in the 5 log-blocks + mK; 3.3 → 5.94 in mK; inner function (√m+1) → (1.5√m+1) in mFblock, mTL1b, mTL2b, mIdb, mL1sqb, mL1L2b, mL2sqb, mL1b, mL2b; mIIM: IIMaj → new IIMaj with 1.5 factor.
Hmm wait — IIMaj: the I_I majorant 2(√n+1)(e^{√n/2}+1)·0.57·2^{−(2√n−2)}. At c = 1.5: length 2T = 2(1.5√n+1) → IIMaj_c(n) = 2(1.5√n+1)(e^{√n/2}+1)·0.57·2^{−(2√n−2)}. The ψ-proof for IIMaj (psiTilde, IIMaj_eq_psiTilde_sqrt, contDiffOn_mIIM) depends on the form psiTilde(√m) = 2(√m+1)(e^{√m/2}+1)·0.57·2^{−(2√m−2)}. Changing √m+1 → 1.5√m+1 changes psiTilde's structure... Let me check what psiTilde is and how the IIMaj ψ-bound was proved (the "analytic IIMaj″ bound ≤ 1.316 < 2 via factor monotonicity" per session 011). The 2(√n+1) factor: at c = 1.5 it becomes 2(1.5√n+1) — that's ≤ 3(√n+1) for n ≥ ... 1.5√n+1 ≤ 1.5(√n+1) ✓ (since 1 ≤ 1.5). So IIMaj_c(n) ≤ 1.5·IIMaj(n) — for the convexity proof, the ψ-analysis of IIMaj was "IIMaj″ ≤ 1.316 < 2" — scaling by 1.5 gives ≤ 1.98 < 2 — still works but tighter. Hmm, or the proof structure: D-057 proved the analytic bound via factor monotonicity. Alternatively keep the convexity proof's IIMaj block with the same machinery at the scaled constant — the margin is huge now (181,256 at 10⁵) so slack is fine.
Actually — wait. Let me think about whether changing IIMaj's inner form breaks `IIMaj_eq_psiTilde_sqrt` and the ψ-block. Let me look at those. Also the convexity proof's overall structure: marginTilde_convex via the ψ-table + IIMaj″ bound. Let me read the convexity theorem and the psiTilde machinery.
4. **SfBoundProp** (2456): range endpoint `(3*10^12 - 1)^2` → the new N₁ = ((3e12−1)/1.5)² = (4/9)(3e12−1)². In Lean: `(4/9) * (3 * 10^12 - 1 : ℝ)^2`? or ((2/3)·(3e12−1))². Cleaner: `((2/3) * (3 * 10^12 - 1 : ℝ))^2`. Let me use that form.
5. **lambda_pos_finite_height_verified** — check its statement for N₁ usage. Let me grep.
6. **LiBasePoints.lean** — the two margin evaluations, re-certify at the new constants (margins improve hugely: 111,917/181,256 — the certified bounds can be ≥ 49,000/109,000 (the c=2 margins) or bigger; better to certify close to the true values: ≥ 111,000 / ≥ 181,000 say).
7. **LiAssembly.lean** (ii′-6-b): the sides identity + bridge. Where does T = √n appear there? The wide pigeonhole instantiation: let me check what `a` the assembly uses. And the bridge's `T ≤ 3×10¹²` step. These may need the 1.5 factor — that's ii′-6-b-redo territory... wait, no — ii′-6-b is already built (session 038) with the OLD constants (T = √n+1 baked?). Hmm. The 8-step protocol: steps 1–5 = 6-a (Bn + convexity + base points + margins); step 6 = resume ii′-6-c with the fixed stepping. But ii′-6-b's LiAssembly (sides identity + bridge) may have T-instantiation assumptions that need updating to 1.5√n. Let me check LiAssembly.lean for how T is produced.
Let me look at these: psiTilde/IIMaj_eq_psiTilde_sqrt, marginTilde_convex, LiBasePoints, LiAssembly T-instantiation, lambda_pos_finite_height_verified statement.
Structure clear. Now checking the convexity proof, the IIMaj/psiTilde machinery, the assembly's T-instantiation, and the verified theorem's N₁ usage.
