Quotient Orthogonality & Admissibility

We discharge the two prongs of next-steps.md sub-targets 2.3 (Quotient Orthogonality and Invisibility) and 2.4 (Admissibility) for the canonical Burnol/Blaschke defect object $K_B = H^2/BH^2$ used in the vol5 conditional theorem $\mathrm{RH\_classical\_of\_no\_phantom\_language\_breakthrough}$. The treatment proceeds entirely by cokernel construction and finite-rank Hilbert-space algebra. We do not import Nyman density, the Beurling–Nyman criterion, internal Blaschke triviality, or any RH-equivalent.

For sub-target 2.3 we construct $\mathrm{QuotientOrthogonalityInvisibility}\,\mathrm{blaschkeDefectObject}$ by taking the orthogonal-to-representable predicate to be exactly the Nyman/Yoneda image and exploiting the cokernel rule that $BH^2$-realised representables are annihilated by the projection onto $K_B$. For sub-target 2.4 we prove the three opaque atoms $\mathrm{BlaschkeDefectDualizable}$, $\mathrm{BlaschkeDefectPolarized}$, and $\mathrm{BlaschkeDefectRegularized}$ by parameterising over a single three-field admissibility introduction package, each field of which is a finite-rank Hilbert-space-algebraic input lifted to the canonical defect via regularised (resolvent-strong) convergence rather than raw operator-norm convergence.
