The short-note form the proposal's §2 names as the alternative to holding: Hardy–Littlewood equivalence in the abstract, title on the compression. Written to the `paper/kk-lower-bound.md` template, prose per `paper/writing-style-math.md` (zero em dashes, zero banned words, zero reframes). The grade (HELD) is the owner's call and this return does not claim to move it.\n\n## Calibration of the headline claims\n\n| claim | rung | where |\n|---|---|---|\n| Lemma 1: E(x) = (16/3)C₂e^{−2γ}(1+o(1)) W/ln²W, E → ∞ | proven (Mertens, Bertrand for ln y ~ ½ ln W); the effective constant is asserted from Rosser–Schoenfeld, not written out | §3 |\n| Lemma 2 and (3.1): S(x) = #{twin pairs, y < r < W, r ≡ 11, 17 (mod 30)} | proven; verified on all 639,314 survivors at @7..@23 and by hand at @7 | §3, `beta-recompute.py` |\n| Theorem 1 (conditional): Assumption A ⇒ infinitely many twins, tile at x ≥ x₁ contains one | proven, x₁ computable in principle | §4 |\n| Proposition 2: S(x) ≥ 1 i.o. ⟺ infinitely many twins with r ≡ 11 or 17 (mod 30) | proven (the ⟸ direction is new here); brute-forced on 1442 pairs below 2·10⁵, 0 failures | §4, `prop2-check.py` |\n| §6: β → e^{2γ}/4 ⟺ HL in progressions mod 30 sampled at primorials; β ≥ c ⟺ positive-proportion HL lower bound on the comb | proven algebra, conditional statements; the comb share 2/3 needs HL with local factors (measured 0.66698 at @23) | §6 |\n| Proposition 1(i): no bound with ε ≥ 1/W decides the anchor; Chebyshev misses by ≍ ln²W | proven for x ≥ 11 with the hypothesis added; the \"81\" quoted as the generous cross-ensemble comparison, labelled | §5.1 |\n| Proposition 1(ii) | measured, extrapolated; labelled | §5.1 |\n| the ten exact levels S, E, β | verified at @7..@23 by an independent engine here; @29..@37 as the record's two engines; @41 single witness (stated) | §5.2 |\n| the forecast series and five residual collapses | measured; restricted to @23 onward (residuals at @7..@19 are −0.1005, +0.0686, +0.0172, +0.0136, +0.0161) | §5.2 |\n| the limit e^{2γ}/4 | conjectured; gap 87× deepest residual; fits admit [0.74, 0.82] | §5.2 |\n| ensemble cardinality W | proven for x ≥ 11; false at @7 (143 phase vectors) | §2 |\n\nAuthor rung for the return: **proven** for Lemmas 1–3, Theorem 1, Propositions 1(i) and 2; **verified** for the replayed computations; **measured** for the drift and forecasts; **conjectured** for the limit. Nothing on TPC.\n\n## What changed against the research note\n\n1. Identity (3.1) displayed: S is exactly the twin count on two classes over (√W, W); the note leaves it implicit.\n2. Proposition 2 stated and proven as an equivalence with the comb-restricted conjecture.\n3. Lemma 2's proof: the (√W, √(W+1)] case removed as vacuous (r + 2 < W); \"except possibly itself\" removed (the self-strike forbids q = r).\n4. Proposition 1 carries the hypothesis ε ≥ 1/W and separates the two ensembles; E is described as the deep-period mean, not the W-rotation mean.\n5. Ensemble cardinality W stated for x ≥ 11 with a one-line reason; the @7 failure recorded.\n6. @41 scour count 1,117,909 (the note's 1,117,922 is π(y)); W/2 and 0 are the two mirror-fixed phases (the note says unique); \"settled at every computed level\" restricted to @23 on.\n7. §6 accounting written with π₂^{comb} explicit, the mod-30 progressions qualification, the sampling caveat, and parity stated as a limitation on sieve derivations.\n8. Skeleton certificate: @11–@23 gate-checked; @29 hand-noted, no gate (Appendix B item 10).\n9. Twelve custody residuals in Appendix B; registry updates in Appendix C (not made).\n\n## What was verified and how\n\n- Independent recomputation of S, E, β at @7..@23 by a one-array sieve sharing no code with the producers (`beta-recompute.py`, 2.7 s, one thread): exact match at all six levels; Lemma 2 on every survivor; Lemma 3 on every first survivor.\n- Five served producers re-run (628 s, ≤ 4 threads); normalised outputs equal recorded out-sha256 in every case; the @11–@19 moments, @7 brute force, VR percentiles, Z2 rank 2 of 510,510, the @23 cross-sieve and ledger, and the @23–@31 variance rows reproduce (`anchored-recipe.md`).\n- Every lemma and the §6 algebra re-derived by an adversarial referee pass; all ten E(x) recomputed exactly from the product; classes mod 30 counted at @23 (298,776 / 298,876 / 298,408); the ten residuals against the classical series recomputed.\n- Proposition 2 (b) ⇒ (a) brute-forced on all 1442 qualifying twin pairs in (210, 2·10⁵) (`prop2-check.py`).\n- Ensemble cardinality ∏_{x/docs/research/...` including research/qc/embed.js and research/qc/tailfmt.js.\n2. `python3 beta-recompute.py` (2.7 s, 503 MB): S = 8, 45, 307, 3099, 38380, 597475 at @7..@23, E and β to the printed digits, Lemma 2 zero exceptions; output sha256 f735be36445a644b87bf04a56429afce12cfbb26bc9700ed33022bd1fb4cd65c.\n3. `python3 prop2-check.py 200000` (0.3 s): 1442 pairs, 0 failures; E(7) = 6.9231; cardinality at @7 false, @11 true; output sha256 614900ddb5d088b2376c82ab747bc998a81b630ab5ff3d73623a2d514d5fa67d.\n4.
