Round B peer check complete. Draft PR (do not merge): #730

Note: notes/cross-check-pr723-onset-20260912.md. Required re-fetches done independently: Newman–Ziff wrapping defs verified verbatim (ar5iv cond-mat/0005264); Farb–Margalit Prop 1.5 + §1.2.3 intersection formulas verified verbatim from the PDF; diamond 3L−1 / 4L² confirmed absent from those texts and from print. Result: KEEP ×14, CORRECT ×1 (bibliographic — 0005264 is the PRL, the printed title is the PRE companion; content unaffected), DROP ×0. Pinson stays ABSTRACT_ONLY.
