The revision ca2b9cae… changes only two places. Every other line of the base is kept byte for byte: the unified diff removes only the three header lines being replaced and otherwise adds lines.\n\n**Header (#26447).** The sentence \"Every figure quoted here is reproduced mechanically from that artifact\" no longer covers everything. It now applies only to the original measured tables and producer outputs, whose custody-bound copy is still the OUTPUT block. The replacement follows the author's provenance erratum (c0a40a66…). It names verification.json (1d5d7cc3…, produced by verify-corner.py against the unchanged source snapshot) as the source of the supplemental exact admissible-band checks in §6. It also says that the exact-root checks and diagnostic band counts that §6 attributes to job #1336 come from that job and its reviews, not from either artifact. Neither set of checks reruns the measured correlation or its timing. The erratum's own text would have left the job #1336 material without a source, so it gets this one extra clause.\n\n**§6, first bullet (#26446).** The unreachability sentence that #2218 deleted is restored in admissible-corner terms, at the end of the bullet and immediately before \"The exact form of that structural claim\". Its wording: neither $x=2^{100}$ nor $x=2^{200}$ is reachable by a sieve over $(x/2,x]$, now or ever, and at the reachable $x=2^{36}$ the admissible band is empty; the degeneracy is structural, not a compute-budget problem, and it is why the admissible corner cannot be measured directly. Placing it there gives \"that structural claim\" a direct antecedent. The bullet's closing note about the producer's legacy labels does not come between them.\n\n**Checks.** I fetched verification.json (sha256 1d5d7cc3…, matches the header) and read it. Its admissible bands at $\\eta_0=1/401$ are $j=36$: $(3,3]$, count 0; $j=100$: $(32,45]$, count 3 $\\{37,41,43\\}$; $j=200$: $(1024,2044]$, count 137. Its single cutoff mismatch is B-eta40 at $j=30$, $E_1$ float $134217727$ against exact $2^{27}$, with `rpHi` 7 both ways. All of these match the figures in §5–§6, so the header's attribution is accurate. Its producer_sha256 1173833a… is the served corner-measurement.js named in review 627. Nothing executable changed, so nothing was rerun.\n\n56 returns wait for a verdict.\n\n## Repair delta\n\n- **Quoted findings.** #26446: \"§6, first bullet: restore the deleted unreachability/structural sentence in admissible-corner terms, so the next bullet's \"that structural claim\" has an antecedent.\" #26447: \"Header paragraph (\"Every figure quoted here is reproduced mechanically from that artifact\"): this is false for the §6 eta_0=1/401 admissible-band counts and the job #1336 exact checks. Apply the author's provenance-erratum-2218.txt (c0a40a66) replacement text, or scope the sentence to the measured tables and producer outputs and name verification.json (1d5d7cc3) / job #1336 for the supplemental exact checks.\" Both are from review 627 of return #2218.\n- **Sources and hashes.** Served base 46b867298bcbaf8f6bfbaa808d0f6f48a50a1ea5c16617787371ad6ccbaa11b7 (return #2218). Prior version 4cfddab77857c3cb611b7ce5afcb0b6daf2543f0f56431211ff549621ef824bc (return #2120), where the deleted sentence appears.

This revision is ca2b9caed1c0abc398c6ad52504285abddfbe1eb56f3e40b73caaad54305e06e.\n- **Prior attempt.** Return #2218 (accepted at verified, with these two before-circulation findings) did two things. It rewrote §6's first bullet into admissible-corner terms but dropped the sentence that \"that structural claim\" refers to. It also added the supplemental exact checks without narrowing the header's \"every figure\" provenance claim.\n- **What changed.** The header provenance sentence is scoped and names its two supplemental sources. One sentence (four lines) is added at the end of §6's first bullet. No other line changed.\n- **Success test.** The header no longer contains \"Every figure\". The phrase \"that structural claim\" now directly follows a sentence that makes the structural claim. In `diff base revision`, the only removed lines are the three old header lines. All of these held on the uploaded file.\n\n## Preservation\n\n- **Return #2120 (accepted; prose scope correction: A-vs-B qualification, widened-eta labels, the $x=2^{36}$ support-vanishing argument), baseline 4cfddab7… → candidate ca2b9cae…: pass.** I read the changed statements. None of #2120's lines is removed or altered, and the restored sentence is #2120's own claim recast in admissible-corner terms.
