Transactional Unimodular Continuous Spontaneous Localization theory (TUCSL) is a proposedsynthesis of transactional quantum ontology, continuous dynamical collapse, q-smeared recordtheory and unimodular gravity. Its central departure from ordinary CSL is that collapse isnot treated as an external pointlike noise source acting on naked local fields. Instead, collapseis a continuous, finite-resolution process acting on physical records: gauge-invariant, BRST-descending, q-local and operationally actualizable structures. The fundamental object is not aclassical stochastic field added by hand, but a transactional record kernel whose dissipative partand noise covariance must descend to the physical algebra.The program claims a distinctive conservation mechanism. CSL-like stress-energy nonconser-vation is not left as a violation of gravity. In the unimodular sector it is closed by a variableintegration datum, written schematically as∇_aT^ab = J^b, ∇^bΛ = 8πGJ^b.Thus the apparent energy defect of collapse is transferred into a variable dark-energy responserather than lost. This makes TUCSL a candidate for an energy-accounting version of CSL.The sequence also proposes q-bandaged black-hole interiors without classical singularities, anaxionless strong-CP solution by modular-CP record projection, a neutral-naturalness sectorcompatible with fraternal twin-Higgs dark matter, and an inter-aeonic remnant mechanism inwhich black-hole record defects seed a later universe through the Big Blur. Its most concreteinternal success is the attempt to derive the CSL length rC and a minimal collapse rate λ^min_mfrom recordability, electronic readout and gravitational clock arguments, instead of treatingthem as phenomenological input parameters.The final LXX–LXXII layer adds three structural modules: K-sourced Abelian-sandpile/c = −2LCFT record screens, a concrete remnant-to-seed channel through screen defects and GNSreconstruction, and a q-Regge–ADM reconstruction of Lorentzian curvature from unimodularrecord sprinklings with the Weyl/K-sector kept separate. Paper LXXIII develops a higher-categorical Yoneda semantics, where physical records are characterized by admissible probe profiles and the Big Blur is formulated as a localization of invisible morphisms. Furthermore, chapter LXXIV presents a Schreiber-style cohesive higher-gauge layer inwhich Hilbertian prespacetime data are modeled as q-admissible differential cocycles, higherholonomies and protected differential charges before open-system record descent. Chapter LXXV develops a a minimallaboratory-kernel theorem in which the CSL-like representative C_q^(lab,min) is derived from electronicrecordability, an Airy–fold transaction threshold and a Diósi–Penrose–Landauer one-bit clock, and a spectralq-kernel construction in which the deep stress-record covariance is defined by positive spectralPlanck reweighting before electronic readout is projected as a completely positive Fisher-windowedlaboratory sector. Furthermore, we propose a gravitational record-channel proposal in which an offer-confirmationcell algebra yields the 1/4 factor of horizon entropy through the Handshake ProjectionLemma and then feeds Jacobson-style local horizon thermodynamics with unimodular CSLclosure. In the end, we develop a modular corner readout channel that replaces flat spectral windows in curvedspacetime by local corner algebras, Araki relative entropy, tracefree stress-noise kernels and anunimodular Einstein–Langevin response.
