Transport Inversion and the Analytic Topography of the Relay Exit

Paper 32 in the "Geometry of the Critical Line" programme. Paper 31 deferred the relay-to-section transfer kernel K_α(x,y) pending robustness testing. This paper subjects the transport inversion — the sign change in the fringe-vs-core bounce advantage — to partition, resolution, and recirculation stress tests. The inversion survives all three, indicating it is a robust feature of the relay-to-section architecture rather than a numerical artifact: it holds across 12 partition schemes, is stable to four decimal places across three spatial resolutions (800×600 to 1600×1200), and persists — indeed amplifies — under second-crossing recirculation dynamics. The existence of the inversion is robust; its location (the…
