Ultraviolet Bounds and the Positivity Obstruction in Brane-Cluster Gravity
A Poisson brane gas yields an ultraviolet-suppressed propagator with a single graviton pole. We realize its transmission multiplier as a unitary matrix coefficient and prove that the resulting gauge-invariant curvature covariance violates reflection positivity. Version 3 includes the manuscript, standalone amsart source, bibliography audit, and revision notes.
