Some transcendental regimes fail to collapse to a least admissible core and yet do not become merely weak. Communicative rationality exhibits that more interesting possibility. In a restricted finitary discourse fragment, iterated self-applicative discourse closure stabilizes to a canonical least self-answering repair, and when that repair is public-essential it cannot remain private: it projects to a recovered public boundary. The argument shows that stabilized discourse edges factor canonically through the public one-hole boundary of the communicative polynomial; that reciprocal role-symmetry and distributed scorekeeping generically obstruct presentation-initiality; that on the singleton-edge reflexive subcategory, repair approximation and public articulation are opposite presentations of the same stabilized public condition; and that, once strict collapse fails, the induced public closure fixes the recovered boundary itself. The philosophical payoff is a distinct transcendental form: communicative rationality can be reflexive-public rather than strict-initial, so the surviving edge is a genuine public interface rather than an accidental remainder.
