Spectral Radius Asymptotics — Transfer Operator.
Redirecting to spectral-radius-v2.html… 2026-09-22. This file and spectral-radius-v2.html were two live copies of the same page. CLAUDE.md already flags this pair as an unresolved same-book version pair pending a newer-wins decision. spectral-radius-v2.html is a near-superset (14 of 15 paragraphs preserved, plus 5 more). One paragraph unique to this copy, on the polar-vortex/Saturn-hexagon empirical certificate, is not carried in v2 -- flagged in docs/audit-log.md rather than silently dropped. Kept as a redirect so external links still resolve, following the convention set by book7/chcurie.html (merged 2026-08-25).
