We formalize an algebraic criterion to distinguish operationally transverse quantum mechanisms from spectrally trivial extensions. We establish a strict topological distinction between admissibility, precision, and exactness in constraint-preserving dynamical systems. Precision is strictly defined as invariant-preserving evolution, while exactness is the zero-residual realization of the invariant target manifold. Spectral gap preservation and a nonvanishing regularized determinant (det₂) are shown to provide the necessary physical stabilization conditions for the convergence of precise dynamics to exact states. By mapping commutator annihilation to Noetherian closure via an Ω-Σ (Omega-Sigma) refinement flow, we prove that legitimate quantum mechanisms must exhibit a bipartite algebraic structure: effective transversality followed by exact commutator annihilation. We further demonstrate that this Noetherian closure is equivalent to a degenerate Floquet regime, where stroboscopic quasi-energy bands collapse onto an idempotent structural projection. The resulting framework provides a closed description of admissible operator evolution. It establishes the Non-Negotiability Principle, which proves that non-structural inputs—such as observer preference—cannot perturb governing dynamics. Ultimately, we demonstrate that unconstrained dynamics do not natively converge to exactness; structural preservation via commutator annihilation is a necessary algebraic condition for admissible operator evolution, providing a mathematical razor to separate genuine quantum advantage from spectrally inert heuristics.
