🔧 Claiming this PR: consolidating the 7 duplicate dem-extra1 narrative-flow/heading-level sweeps into this one (the largest/most complete). Merged main in to clear the "behind" state (main had advanced via #1173's CI fix). The other six (#1172, #1171, #1167, #1166, #1164, #1163) are closed as duplicates; uncovered content from them is tracked in #1174. Driving this PR to clean and watching it through merge.

Review: d-morrison/rme#1168

PR status confirmed: open, unmerged (per authoritative API state passed into this run).

What changed since the last review round: I verified the computed range eefe60d0..11e5bfb6 directly with git diff --stat and git log. It touches only two .github/workflows/ files (_check-ai-tells-bypass-reusable.yml, check-ai-tells.yml), introduced by commit 681ecbc ("ci: fix stalled PRs by bypassing check-ai-tells cleanly (#1173)"). I confirmed 681ecbc is already an ancestor of origin/main (git merge-base --is-ancestor 681ecbc origin/main → yes) — it's a separate, already-merged main-branch commit that landed on the PR branch only because of the routine Merge remote-tracking branch 'origin/main' into <branch> housekeeping commit, not new content authored for this PR. Since that commit is identical on both sides of the merge base, it produces no net diff between this PR and main — which is exactly why .claude-review-pr.diff (the actual PR-vs-base diff) contains zero .github/ hunks and only the previously-reviewed .qmd prose/heading changes.

I read the full .claude-review-pr.diff (718 lines) end-to-end and confirmed every hunk in it — the ##/### → #### heading-level fixes across data.qmd, estimation.qmd, exploratory-descriptive.qmd, inference.qmd, coxph-model-building.qmd, count-vars.qmd, and the various _subfiles/; the --- → {{< slidebreak >}} swap in _def-cond-expectation-function.qmd; and the "that is"/bare "This is" prose rewordings — matches content already covered and found clean across the two prior review rounds (8c6e260 and eefe60d0). No genuinely new content-diff exists in this round for me to review.

Since the CI-workflow commit that produced this round's re-trigger is infra-only, came from main, and produces zero net diff against the PR's base, CLAUDE.md's "Workflow / .github/ / CI / infra changes go in their own dedicated PRs" rule doesn't apply here — it wasn't authored as part of this PR's changeset, it's just merge-commit noise from keeping the branch current with main.

The most recent prior review — posted 2026-09-14T21:47:47Z, run 34900579149, reviewing commit eefe60d09b635cd4fd982c7f5eed6e20ee588608 — concluded Ready for merge with no findings, and explicitly noted that the original full-content review (posted 2026-09-14T21:32:40Z, run 34899078524, commit 8c6e26017240653b300d29a74624ace5f88f9f6e) also found the diff clean (heading-level fixes correctly scoped inside theorem divs, the slidebreak swap correct, prose rewordings accurate and grammatically sound, no macro/citation/hallucination issues). Both verdicts still stand — this round introduces no new PR content to invalidate them.

No macros submodule check was newly needed: no math was added or changed in this round's diff (confirmed above — zero net PR-vs-base diff beyond what was already reviewed, and the earlier rounds already established no math changes exist in this PR at all).

Verdict

Ready for merge — no new findings; this round's only diff is main-branch CI housekeeping that nets to zero against the PR's actual content, and the prior rounds' full-content review (both concluding CLEAN) still stands.
