CDN-209: The Resonant Chain Map

CDN-209 maps TRAPPIST-1 as a compact seven-planet resonant timing lattice using NASA Exoplanet Archive pscomppars data. All six adjacent pairs sit near low-order commensurabilities, with maximum pair detuning 1.317941%, and all five consecutive triplets admit small Laplace residuals, with the shortest mapped beat period 4847.318 days. The result pays a carrier-geometry claim only: no TTV residual, entropy-time amplitude, atmosphere, habitability, or biosignature-persistence claim is paid.
