Observable-Rank Stability under Vertical Non-Injectivity: Closing the Fibre-Structure Conditionality in the Born–Infeld-to-Cascade Chain

O18 establishes Born–Infeld parity as a covariance of the response family of ${S_{\mathrm{BI}}}[\chi]$ and states the identification of the parity orbit with a fibre of the non-injective projection $\Pi$ as an open problem; the hypothesis that parity is the only global symmetry o...
