A Nonremovable Meromorphic Map into a Ball on a Codimension-Two Wedge

Abstract
We construct a meromorphic germ in C^3 that is holomorphic from an attached wedge into the open unit ball, extends continuously to its real-algebraic generic edge with values on the unit sphere, and nevertheless has no holomorphic extension to a full neighborhood of the edge point. The edge has real codimension two and CR dimension one. An explicit rational sphere identity is combined with a holomorphic factor that is unimodular on the edge and suppresses interior norm growth. The boundary limit holds along every wedge approach, not just normal rays. This gives a negative answer to the arbitrary-generic-edge question posed by Meylan in the 2010 AIM CR-mapping problem list, with convergence understood from inside the ball. The example is nonminimal and has a continuous but nondifferentiable boundary map; it makes no claim about strengthened minimal-source or smooth-boundary-map formulations. The manuscript is AI-assisted, self-audited and unrefereed. No independent review, formal verification or absolute priority is claimed.
