Canonical Certification Does Not Exhaust Reflective Structure: Reflective Split, Strict Refinement, and Fiber Structure in Infinity Compression

Formal theories often collapse many derivations to a single canonical certified record: the question is whether that collapse exhausts everything structurally significant about the realized routes that produced it. This paper is the internal origin theorem of a larger program: we prove that it does not, on named machine-checked carriers in the Infinity Compression native environment. We prove universal collapse of standard Phase-2 extraction to a unique bare certificate; a reflective split (canonical bare certification alongside nontrivial enriched autonomous mirror structure) ; strict refinement of the typed forgetful map A (existence of distinct enriched reflective splits with equal A-image) ; and a forgetful--fiber layer in which the canonical fiber is nontrivial and role assignme
