v1.4.9 — Second-opinion prose review: 2 more passages
Follow-up to the two prior plain-academic-prose passes. An independent second review, cast against a wider set of criteria (casual interjections, rhetorical asides used as a stylistic tic, hedging phrases), found two more instances: “Reassuringly” in the path-algebras chapter, and a “sound familiar?” rhetorical aside in the Mathlib chapter. Both rewritten as direct statements.
