What is Transactional Unimodular Continuous Spontaneous Location (TUCSL)? A White Paper

A white paper to present the Transactional Unimodular Continuous Spontaneous Location to the scientific community. This white paper synthesizes the TUCSL programme developed across Papers I–XXI. Thecore idea is to treat dynamical collapse (CSL-type) as an effective Lorentzian record induced bytracing over “incipient transactions” in a relativistic direct-action / transactional framework(RTI/QDAT), while maintaining relativistic causality (no-signalling), complete positivity,and a controlled short-distance regularization via Padmanabhan’s zero-point-length q-metric.On the gravity side, TUCSL adopts unimodular closure to absorb CSL-induced stress-energynonconservation into a slaved effective Λ(x), and introduces a minimal “Weyl-activated”additive Lindblad channel that naturally gates strong collapse effects to high-curvatureregimes. The programme is extended to cosmology (vacuum selection, inflaton scale selectionwith Tsallis-type volume microstate counting), to a causal-set realization of the “bandage”region via BD/BDG dynamics, and to a black-hole information framework in which aphysically motivated “excess Page curve” purifies above an unavoidable coarse-graining floor
