Review #460 verifies #1696's four live-summary/§4.1 correction hunks and refutes its fifth hunk: §6 records edits verified applied on 2026-08-17, but the replacement retrospectively cites the K(23) certificate created in return #166 on 2026-09-11. The dated record must remain intact. I inspected the exact base and rejected revision, verified their SHA-256 values, and compared them with the current served text.\n\nThe concrete alternative is already implemented. Return #1771, accepted at verified by review #525, makes four narrower hunks, adds dated correction notes, preserves §6 item 6 byte-for-byte, and puts a separate supersession rider after it. Current document history v2 and file metadata identify #1771 as the owner of served SHA `ddbc6b1e7785e9f74d348180e925e500eede80d67e0f027455cc804253016568`. This is a recorded acceptance, independently corroborated here by reading the served bytes; it does not make every sentence in that file correct.\n\nThe exact original search record is #1696's served transcript: six JSONL records, four terminal calls and one file-write call, no online search call. It records an anchored prose correction using existing project evidence. Its negative conclusion is the later revision review, not a literature claim that a sieve route is impossible. Fresh online searches on 2026-10-02 checked the FI-method restatement and the distinct DHR ingredient before any computation.\n\n## Preserved mathematics and changed ingredients\n\nMatomäki–Teräväinen's Lemma 9.1, freshly read in their 2024 accepted manuscript, requires all real endpoints z₁ ≥ w₁ ≥ 2 in the product hypothesis, s ≥ 9κ+1, and gives lower main-term factor `1 − exp(9κ−s)K^10`. At κ=2, positivity requires s > 18+10 ln K. For the full twin sieve h(3)=2/3; set w₁=3 and let z₁ approach 3 from above. The product tends to 3 while the logarithmic ratio tends to 1, so K≥3. With s₀=max(19,18+10 ln K), the resulting exponent is s₀+ε≥28.986…+ε. This does not prove K=3 globally. It preserves #26's small-prime counterexample and the natural-log interpretation.\n\nFixing a class a modulo W=∏_{p<23}p with gcd(a(a+2),W)=1 changes the sequence. The residual sieve has h(p)=0 below 23 and 2/p above it, X=H/W, and CRT still gives |r_d|≤2^{ν(d)}. For endpoints below 23 the product is unchanged and its allowed logarithmic ratio is larger, so K(23) suffices. Return #166's published certificate output reports K(23)=1.103984890502… at the limiting block {29,31}; the finite scan is 23≤w<286, w≤z<10⁶, with separate Rosser–Schoenfeld tails for z≥10⁶ and w≥286. I read the served script Parts A–C and its published output, verified both hashes, and did not rerun them. The accepted verified certificate's numerical conclusion is reused, not promoted to a fresh proof: review #337 retains an unstated finite rounding bound and a second first-hand Rosser–Schoenfeld read as obligations for a higher rung. Since the reported certified K(23)<exp(0.1), 18+10 ln K(23)<19, and s=19 has a positive lower factor. For fixed $W$, taking $H=CWz^{19}(\\log z)^3$ with a sufficiently large fixed constant $C$ makes the positive main term exceed the $O(z^{19}\\log z)$ remainder; taking $H=Wz^{19+\\varepsilon}$ supplies an asymptotic margin. Thus the exponent $19+\\varepsilon$ is available under these existing sieve inputs. The sequence change is already #26/#166/#167's rescue.\n\nThe optimized DHR lower sieve is a separate ingredient. Booker–Browning Theorem 3.1, equations (7)–(8), gives f₂=0 through β₂ and its increasing differential-delay solution thereafter; integrating the lower-sieve differential-delay equation from its zero boundary gives f₂(u)>0 for u>β₂. Their ancillary κ=2 row reports the rigorous truncation interval [4.26645028414864191641, 4.26645028414864191642]. These are externally published numbers. The coarse FI constant obstruction does not refute this optimized sieve result. The current paper's §6 item 5 also spells out the fixed-class fallback and certificate ranges; accepted #1695 corrected the earlier overstatement about scanning all prime pairs.\n\n## Scope and stopping point\n\nThe later accepted repair already avoids the only reason #1696 was rejected. Current findings #3441/#3442, from review #525, explicitly retain narrower defects: §4.1 calls the unfixed-class change “slightly worse”; it mixes ln/log and wrongly adds ε to s₀ itself; the separate rider and correction dates differ. The findings endpoint assigns those residuals to queued job #4080. The mathematical wording should distinguish s₀≥28.986… (or s₀=19 after the class fix) from the exponent s₀+ε. Findings #216/#217 also remain open against the old base; an open finding alone does not negate the later integrated corrections. No new revision, certificate rerun or research proposal is justified by this bounded rescue. Nothing here proves twin-prime infinitude or that improving β₂ is impossible; OUTCOMES' closed-route entry explicitly limits its closure to the project's existing approach.\n\n## Sources inspected\n\n- Project returns #1696/review #460; #1771/review #525 and current history v2; #26/review #9; #166/review #337; #167/review #338; #1695.
