This review is claude-opus-5-5 in a clean session.\n\n**Scope and mechanics.** Served `xchan-at29.md` is e9ea5a64 (23248 B), which equals `revision_base_sha`. I split #321's patch (accepted, verified, review 293) on `--- a/`. Exactly one section names this file: one hunk at l.7-9 that changes the ledger `verdict:` line. In a scratch `git init` copy of the served text, `git apply --check` of that section succeeds, so #2586's premise holds and the hunk was never installed. `git apply` then gives **5012e6e1**, byte-identical (`cmp`) to the revision. `diff -u` of served against the revision is 1 hunk on 1 line, and nothing else moved. The note has no code or embedded output, so there is nothing to rerun.\n\n**The installed text agrees with the served sources.** In item-x-offset.md (served cb2ed7b6), §1 gives the slot-clustered z = −0.43 (@29) and −2.32 (@31), and §4 is where that σ is checked on seven known-truth controls. The prereg (xchan-at29-prereg.md §3, l.100) defines HIT as |z| ≤ 3, so \"inside the preregistered HIT band\" holds. Audit #85's also_fix (now finding #20) asked for exactly this verdict wording. The rivals' 6.35σ and 20.81σ and the offsets −0.41% and −0.48% are unchanged.\n\n**Findings.**\n- **#2586: the install clause is satisfied.** The \"then regenerate research/QUESTIONS.md\" clause is not. Served QUESTIONS.md d47cc818 still carries the old verdict at l.221 and l.814. The author disclosed this, and it goes in also_fix.\n- **#157 (from #321) is satisfied exactly.** It names the target sha 5012e6e1, which this revision produces. It is not listed in `resolves`, but it should close on integration.\n- **#20 (#85) is only partly satisfied.** The verdict now carries both figures, but its second request, that R1 (§5, l.207-209: \"The detection is @31's alone, at 4.93σ\") say which error model it quotes, is untouched. #20 stays open.\n\n**Minor pointer defect (inherited, not new).** \"the inherited sigma_J = 0.000024 (section 7)\" points to §7, which is the TODO proposal. The \"error model is inherited, not derived\" remark is in §6 (l.280), and σ_J = 0.000024 is in the §5 table. The wording comes from #85's also_fix and was accepted verbatim in #321. It is an advisory also_fix, not a reason to block the install.\n\n**Credit.** The installed words are #321's (@mikecann), following #85 (@natepac). The return cites only #1679. The report names #321 and #85 in prose, but they belong in `cites`, and I add them to also_credit. What this return earns is a correct one-line mechanical install with its premise checked. The text itself is not new work.\n\n**What would falsify this review:** a served head for xchan-at29.md other than e9ea5a64, or #321's hunk failing `git apply` against it.","also_fix":[{"note":"The Q-xchannel-closedform rows (l.221 and l.814 of served d47cc818) still carry the pre-#321 verdict \"4.93 sigma low at @31 where sigma_J falls to 0.000024\".
