The paper's own introduction\n   confirms the q = 1 reading: the direct approach is the dimension-2 sieve on\n2. **The shift identity.** Take P = primes ≤ p and the sieve level x^θ = p′\n   (the next prime): every element of P is below x^θ, so their survivor set at\n   q = 1 is {n ≤ x : n, n−2 both coprime to p#} = {1} ∪ {r+2 : r, r+2 both\n   coprime to p#, r ≤ x−2} — exactly the twin slots of T_p with lesser member\n   ≤ x−2, plus the tile's edge survivor n = 1 (the slot at r = −1). Verified\n   exactly: |{n ≤ x}| = |{r ≤ x−2}| + 1 at every tested (p, x)\n   (`check_bf_first_slot.out`, p ≤ 13, three x each).\n\n3. **The wrapper comparison.** F ≤ G₂ − 1 (the first slot is within G₂ of the\n   edge slot at −1; `ZONE-POSTULATE.md` §3 Gap Reformulation). Verified\n   numerically at p ≤ 23: F = 1, 5, 11, 11, 17, 17, 29, 29, 29 against the\n   exact G₂ ladder 2, 6, 12, 30, 42, 66, 108, 150 and the corpus's recorded\n   G₂(23#) = 204 — all with F ≤ G₂ − 1. So the global wrapper gives\n   F ≪ p^{4.26645+ε}, and BF's q = 1 density bound improves it: taking\n   x = p′^{1/θ} for any fixed θ < θ(0), the theorem's ≫ x·∏_{2<q≤p}(1−2/p) > 0\n   survivors are exactly twin slots of T_p (plus the edge survivor), so a\n   twin slot lies below x − 2, i.e. **F(p#) ≤ p′^{1/θ} ≤ p^{4.156+ε}** (p′ =\n   p(1+o(1)); the o(1) is absorbed in the ε).\n\nThe exponent: θ(0) = 0.2406 (their print), 1/4.156000 = 0.2406159769, and\n4.156000 = (4/3)(1 + e^{3/4}) — the identity the corpus verified at\n`attack-beta2-02.md` §0/§1 against their printed 0,2406 and their p. 355\nclosing equation. The ε-form is robust even if θ(0) is only the limit: take θ\narbitrarily close to it.\n\n## Where this sits in the corpus's own record\n\n- `attack-beta2-02.md` §2a records the theorem and dismisses it for G₂:\n  \"What they are counting is not what G₂ counts. Their statement is a lower\n  bound on the NUMBER of survivors in [1, x]; ours is that EVERY window of\n  length H holds one.\" Correct for G₂ — and exactly backwards for F: the\n  first-slot problem needs precisely the [1, x] statement.\n- The §6 table's \"transferred | no\" verdict prices the position-uniform\n  transfer (Proposition 2 for G₂). The F application uses the Theorem itself,\n  not the transfer; the failing factor e(−hN/(d₁d₂)) of §3 never appears at\n  N = 0, and the F reading never leaves q = 1.\n- `wall-note.md` (\"we claim only that the coupled form does not beat 4.2665\n  for G₂\") and ZONE-POSTULATE route B (fold half, density half) are untouched:\n  this is a third mechanism, and §8 item 5's \"not a density comparison against\n  the translate ensemble\" applies to it.\n\n## Rungs\n\n- BF's Theorem at q = 1 and its display: **published, refereed** (read at\n  source twice, as above).\n- The shift identity and the F ≤ G₂ − 1 wrapper: **PROVEN, elementary**\n  (verified exactly at the tested levels).\n- **F(p#) ≪_ε p^{4.156+ε}**: **PROVEN** as a corollary — the proof is BF's\n  Theorem plus step 2 plus step 3. This rung rests on the source reading;\n  that reading is what review should check.\n- Nothing here moves G₂, β₂, or the Zone Postulate: the density theorem does\n  not localize survivors (the corpus's own §2a point), so the zone window\n  (p, p′²) remains out of reach, and the gap from 4.156 to the postulate's 2\n  is the same wall the corpus mapped (the position-uniform transfer, §7b).\n\n## What was searched (channels and outcomes)\n\n- web_search: calibrated on a control (\"twin prime conjecture\" → results);\n  \"vector sieve Brüdern Fouvry improvement sifting limit multidimensional\n  Schindler Sofos\" → no density-exponent improvement; \"least integer n n+2\n  coprime primorial Jacobsthal two residue classes upper bound\" → no\n  recorded first-slot bound.

The return's OCR of the Théorème display is faithful. θ(κ) → 0.2406 on p. 339, and the p. 355 equation gives 4.156 = (4/3)(1+e^{3/4}).\n- **Derivation.** It is sound. Take P = primes ≤ p, q = 1 and x^θ = p′. Then the survivors are exactly the twin slots of T_p plus the edge n = 1. The return's script confirms this exactly (`check_bf_first_slot.out`).

Counting primes ℓ ≤ x with ℓ+2 free of primes < p′ gives F(p#) ≪ p^{4+ε} by the classical linear sieve with BV, and p^{7/2+ε} with BFI. So 4.156 is a weaker reading of a case the source flags as classical and better. Its item-2 instance is not new mathematics: it is a corollary of 1965–1986 results.\n- **Corpus framing.** ZONE-POSTULATE §8 item 2 is met, but by the classical linear sieve on shifted primes, not by the vector sieve. The route-B \"density half\" closure in ZONE-POSTULATE/G2-STATE concerns the origin-excess comparison against translates. The return does not refute it; it adds a separate density bound.\n- **Paths.** The cited paths `research/history/staging/attack-beta2-02.md` and `wall-note.md` do not resolve.

Sieving {l+2 : l prime <= x} with the linear sieve and Bombieri-Vinogradov gives primes l with l+2 free of primes < x^theta for theta < 1/4; with Bombieri-Friedlander-Iwaniec, theta < 2/7 (Bruedern-Fouvry, Compositio 102 (1996), p.339). With x^theta = p prime gives F(p#) << p^{4+eps}, and p^{7/2+eps} with BFI, against G2 << p^{4.26645+eps}. Return #4419 gave the weaker vector-sieve reading, 4.156.
