PR is confirmed open, not draft. This matches the authoritative status already provided. I've reviewed the delta since the last round.

Review

What changed since the last round: Only binom.likelihood.app.qmd (commit 0e96bb4), reflowing a single long paragraph into one sentence per source line. I diffed the file content at both commits (63625646 and 712c46af) directly: the prose text itself is byte-identical except for line breaks — "our data are generated" (the subject-verb fix from the prior round) is unchanged, and no words were added, removed, or reordered.

This reflow is a direct, correct application of the CLAUDE.md rule: "One source line per major phrase in prose — keeps git diffs readable and review easier." Each new line break falls at a natural sentence/clause boundary ("...as seen previously." / "Larger sample sizes..." / "...with larger sample sizes." / "We also see..." / "...5% of the time." / "In this set of simulations," / "our data are generated under the null hypothesis," / "so our ability..."), so the rendered Markdown is unaffected (soft line breaks collapse to spaces) — this is a source-only formatting improvement, not a content change.

I re-checked this against the "don't flag cosmetic source-only formatting that renders identically" guidance: this isn't a flag, it's confirmation the change is a genuine, harmless improvement consistent with the repo's stated diff-readability convention.

No LaTeX/math was touched in this delta, so there's nothing to check against latex-macros/macros.qmd for this round. No new factual claims, citations, or computed values were introduced. No hallucination risk in a pure line-wrap change.

The rest of the PR (all the ###→#### heading-level fixes and demonstrative-pronoun fixes across the various _subfiles/, plus the earlier typo/grammar fixes) is unchanged from the prior round and was already reviewed clean in the 2026-09-16T21:01:29Z summary (verdict: Ready for merge, commit 636256465a72689ddcd9d55b2a70a0732c17a285). That verdict still stands — no regressions or new issues introduced by this round's change.

Closing as a duplicate. This PR is one of seven automated dem-extra1 (Jules) PRs that ran the same "improve narrative flow / clarify demonstrative referents / fix heading levels" sweep with heavy file and content overlap (#1172, #1171, #1168, #1167, #1166, #1164, #1163). Rather than driving all seven through review separately for the same defects, #1168 (the largest/most complete sweep) is being kept and driven to merge. Content this PR touches that #1168 doesn't cover is tracked in #1174.
