Records and Responses in the World: A derived fine-structure boundary, certified confinement gaps, and registered discriminators for a finite record substrate

This physics companion applies the records/responses measurement discipline to finite-information models: records define what can be known, while response functionals define what experiments measure. The paper consolidates current response-layer results for the finite-QEC substrate, including the QED boundary response, electroweak pole exposure, certified confinement statements, black-hole response maps, trans-LambdaQCD transfer, and dark-sector/lensing discriminators.
