The convexity proof structure is fully clear:
- `vF`: mFblock's deriv2 = (−2)·(psiOf F/(4n)) — with mFblock := (−4)·F, this becomes (−4)·(psiOf F/(4n)); hnn1: nonneg because the coefficient (−2 or −4) is nonpos and psiOf F < 0 → the `by norm_num` discharges the coefficient-sign: `mul_nonneg_of_nonpos_of_nonpos (by norm_num : (-2:ℝ) ≤ 0) ...` — with −4, `by norm_num : (-4:ℝ) ≤ 0` works the same ✓ mechanical.
- `vTL1`: mTL1b's coefficient ((8/3)*0.433+42) → ((8/3)*0.6+42): appears in vTL1's equation (rw [deriv2_const_mul _ ...] — the constant is inferred from the unfolded def) and hnn2's `by norm_num` (the constant is negative either way ✓).
- `vId`: mIdb's ((8/3)*2.9+192) → ((8/3)*2.7+192): appears in vId's `show (fun m => -(8/3*2.9 + 192) * ...)` — the show must be updated to the new constant; hnn4's norm_num ✓.
- All other rows unchanged.
So the convexity proof is almost mechanical: the constant changes propagate via the unfold + deriv2_const_mul, and the sign haves use `by norm_num` which handles any specific numeral. The only text edits: the def constants (mFblock/mTL1b/mIdb), the `show` in vId, and possibly hnn1/hnn2/hnn4's hardcoded constants if they're written literally (hnn1 has `-2 * ...` literal in the statement — update to -4; hnn2 has `(-((8/3)*0.433 + 42))` literal — update; hnn4 has `(-((8/3)*2.9 + 192))` literal — update).
Let me also check marginTilde_eq_expanded (simp only + ring — should survive verbatim since it unfolds the defs) and marginTilde_eq_sub (simp only [marginTilde, Bn, sInftyLower] — survives).
And check what `hnn1` looks like after the F change — vF's statement: `deriv (deriv (mFblock F)) n = (-2) * (psiOf F (Real.sqrt n + 1) / (4 * n))` — the (-2) is deriv2_const_mul's constant extracted from the def — after changing mFblock to (-4), the unfold+rw produces (-4). The vF statement text has the literal (-2) — must edit to (-4). Similarly vTL1/vId literals.
Then LiBasePoints: marginTilde_FAlt_80000_pos (0 < marginTilde FAlt 80000) and marginTilde_FAlt_80000_lt_100000 (marginTilde FAlt 80000 < marginTilde FAlt 100000). These are certified by rational interval bounds — the certified values were margiñ(8×10⁴) ≥ 8001 (true 15,764) and margiñ(10⁵) ≥ 85,501. With the corrected Bn:
- margiñ(8×10⁴)_new = margiñ_old + (Bn_old − Bn_new)(8×10⁴). Bn_old − Bn_new = (2F − 4F) + 4T·(2/3)(Ĉ₀−Z2) = −2F + 4T·(2/3)·(2.9−2.7 + (0.433−0.6)·L) = −2F + 4T·(2/3)·(0.2 − 0.167L). At n = 8×10⁴, T = 283.84, L = log(285.84) = 5.655: = −2·259.2 + 4·283.84·(2/3)·(0.2−0.944) = −518.4 + 757.6·(−0.744) = −518.4 − 563.7 = −1082. So Bn_new(8×10⁴) = Bn_old + 1082 → margiñ_new(8×10⁴) = margiñ_old − 1082. Wait — the corrected Bn is LARGER at 8×10⁴? Let me recompute with E-030's numbers: at n=10⁵: Bn_baked = 341,861.50, Bn_honest = 343,096.52 — the corrected Bn is LARGER by 1,235 at 10⁵! But margin_honestBn(10⁵) = 90,652.75 vs margin_bakedBn(10⁵) = 91,887.77 — the honest margin is SMALLER by 1,235. Hmm! Earlier I said "honest B is smaller near 10⁵" — that was the honest ASSEMBLY (224k) vs baked Bn (342k). The corrected Bn (which is what margiñ uses) is BIGGER than baked Bn by the killers (+2F + I_III correction) minus nothing. So margiñ with corrected Bn DROPS by ≈ 1,082 at 8×10⁴ and ≈ 1,235 at 10⁵. The certified bounds were ≥ 8001 (true 15,764) and ≥ 85,501 — after the drop: true values ≈ 14,682 and ≈ 84,266 — both still comfortably above the certified thresholds. Good — the re-certification with the same thresholds should work (maybe even reuse the same certified constants since the interval bounds had slack — but the value changed so the computation must be redone; the slack was large).
Wait — E-030's margin columns: at n=10⁵: margin_honestBn = 90,652.75, margin_bakedBn = 91,887.77. The certified margiñ(10⁵) ≥ 85,501 — new true margin 90,652 > 85,501 ✓ still certifiable with the same threshold. At 8×10⁴: not in E-030's grid; compute: sInftyLower(8×10⁴) = 0.5·80000·log(80000) − 1.41894·80000 − 4 = 40000·11.2898 − 113,515 − 4 = 451,592 − 113,519 = 338,073. margiñ_old true = 15,764 → Bn_old(8×10⁴) = 338,073 + 1 − 15,764 = 322,310. Bn_new = 322,310 + 1,082 = 323,392. margiñ_new = 338,074 − 323,392 = 14,682 ≥ 8001 ✓.
OK. Now execute. Order:
1. Edit LiSkeleton: Z2hat def + Bn + marginTilde + mFblock/mTL1b/mIdb + vF/vTL1/vId literals + hnn1/hnn2/hnn4 literals.
2. Build LiSkeleton — check marginTilde_eq_expanded/eq_sub/convex.
3. LiBasePoints: check if the certified bounds still go through (they compute the margin value from marginTilde's def — the def changed so the arithmetic changes; the proofs use interval arithmetic with specific rational bounds — need to check how robust: marginTilde_FAlt_80000_pos proves 0 < marginTilde FAlt 80000 via lower-bounding each component; the changed components (4F, (2/3)Z2) enter with their interval bounds — the proofs will break where the specific old coefficients are used. Let me look at LiBasePoints' structure for those proofs after the LiSkeleton edit goes through.)
Let me start the edits.
The structure is fully mapped. Executing the edits: Z2hat def + Bn + marginTilde + the three changed blocks + their ψ-row literals.
