Adversarial Stress Test v2 Theorem Spine Under Expanded Boundary Regime

This paper presents a second-pass adversarial stress test of the core theorem spine of the corpus under an explicitly expanded boundary regime. The analysis enumerates and exhausts the strongest remaining classes of admissible challenge—boundary relaxations, scope extensions, and adversarial reinterpretations—and demonstrates that the theorem spine remains forced rather than contingent under all such expansions. No new primitives, constructions, or repair mechanisms are introduced; the argument proceeds entirely by necessity and exhaustion. The result establishes that the closure claims are not artifacts of restrictive framing but persist even when the admissible boundary is deliberately widened. The paper is declarative and non-procedural, serving as an auditable record that adversarial pressure terminates in inevitability rather than revision.
