This follows review #162 of return #1323 and the served wall-note Face 1.\n\n**What changed.** §9 said two-class sieves \"carry a parity floor of 2 against the needed constant 1.28 at @17\". That sentence is replaced with the dimension-2 reading. Two classes per prime, uniform in the window's position, is a sieve problem in dimension $\\kappa = 2$. The operative floor there is $8$: it is the parity floor of Selberg's $\\Lambda^2$ at $\\kappa = 2$, and it is also the best constant in print that survives the position quantifier (Riesel–Vaughan Lemma 5). The margin at @17 is $8/1.28 = 6.25\\times$, not $2/1.28 \\approx 1.56\\times$. The figure $2$ is kept, labelled as the dimension-1, whole-range bound. It is valid *a fortiori* but is not the barrier here. The text also says that no $\\kappa = 2$ extremal example is in print, so $8$ is the best known constant, not a proven floor. It states that the earlier reading is withdrawn. No other line changed: one hunk, 3 lines out and 15 in. The rest of §9 and §8's \"wall of §9\" cross-reference still read correctly.\n\n**Evidence, checked against the served sources (rung: verified, read at source plus arithmetic):**\n- `research/history/staging/attack-lichtman-decomp.md` §5 gives $F_2(2)\\,|A|V(z) = 2e^{2\\gamma}\\cdot 4e^{-2\\gamma}\\,\\mathfrak S = 8\\,\\mathfrak S$. It says this is best known, not proven, because no $\\kappa=2$ extremal set is known. §7 gives the margin $8/1.28 = 6.25\\times$ and withdraws the 1.56× reading.\n- `research/natal-cap-10-sieve-cap.md` §1.4: the constants below 8 need equidistribution of primes in arithmetic progressions, which is not position-uniform. The position-uniform constant is $8+o(1)$ (Riesel–Vaughan Lemma 5). The same file's §2 gives 1.28 as the constant needed at @17.\n- The served `paper/wall-note.md` Face 1 (sha 8d863a97…) already has this reading, and its line 334 asks for exactly this change to the note.\n\n**Hashes.** The note embeds no hashes and no runnable code, so nothing needed re-embedding or re-running. Served file a7d5f57a… plus `patch` gives 5407809b…, the uploaded file (checked with `git apply` and `cmp`).\n\n**Not changed:** #940's rider on the ensemble description is a separate item and was not touched.\n\n46 of @Benjaminsen's returns wait for a verdict.\n\nTranscript: this assignment's slice only. Removed: session/account/launch ids, the token and its prefixes, and local paths outside the working directory.","patch":"diff --git a/paper/anchored-note.md b/paper/anchored-note.md\nindex b8a0642..645b73c 100644\n--- a/paper/anchored-note.md\n+++ b/paper/anchored-note.md\n@@ -355,9 +355,21 @@ and the comb carries the twins ≡ 11, 17 (mod 30), the statement\n π₂-on-the-comb ~ (4/3)C₂W/ln²W, the Hardy-Littlewood asymptotic in Mertens\n normalization.
