Transactional Unimodular Continuous Spontaneous Localization (TUCSL) is a proposed reconstruction of dynamicalcollapse theory in which the transactional interpretation is combined with continuous, non-pointlike record actualization.The collapse is not a punctual jump imposed on an already given spacetime. It is modeled as a q-smoothed, completelypositive record channel acting on transactional offer-confirmation structures, with stable records becoming theoperational substrate from which Lorentzian geometry, matter records and macroscopic classicality are realized.The central architectural novelty is the coupling of continuous collapse to unimodular gravity. In standard CSL, energynonconservation is one of the main conceptual and phenomenological liabilities. TUCSL instead treats the CSL-inducedstress-energy defect as an exact-sector source in unimodular closure: local nonconservation is not left as a freeviolation, but is slaved to a variable cosmological response, so that the missing energy is transferred into adark-energy-like integration sector. Dark energy is therefore not introduced as a new scalar substance; in the TUCSLsequence it becomes partly the observer-facing response of unimodular closure, and partly the FLRW compression of amore inhomogeneous Szekeres-Szafron record geometry.Across the 69-paper sequence, TUCSL develops conditional theorem-schemas for black-hole interiors, cosmology,low-energy field theory, and inter-aeonic renewal. The programme claims no completed theory of quantum gravity andno proof of every stability estimate. Its sharp claims are conditional: singularities are replaced by failures of infiniterecordability under q-bandage damping; strong CP is addressed without an axion by non-descendence of the CP-odddeterminant-line/topological record phase; neutral naturalness supplies a compatible twin-Higgs sector for the hierarchyproblem; and black-hole evaporation can leave protected remnant record defects that seed a later aeon through the BigBlur.The strongest internal achievement of the current sequence is parameter closure. TUCSL derives a laboratory CSLcorrelation length from a local electronic recordability principle rather than choosing it phenomenologically: r_C = l_Pl [ln2 alpha D_e^2]^{1/3}, with D_e the Dirac-Eddington electron force ratio, giving r_C about 7.2 x 10^{-8} m. Thecomplementary minimal collapse clock is then obtained from a Diosi-Penrose-Landauer one-bit gravitational self-energyrate, lambda_m^{min} = G m^2/(hbar r_C ln 2), yielding the nucleon-normalized lower rate. In this sense TUCSLattempts what ordinary collapse models have not done: derive the benchmark length and a minimal collapse rate from arecord-theoretic principle rather than inserting them by hand.

Transactional Unimodular Continuous Spontaneous Localization Theory (TUCSL) is a theoretical research programme exploring whether quantum measurement, spacetime emergence, gravitational backreaction, cosmology and black-hole interiors can be described within a single record-based open-system framework. The programme combines continuous spontaneous localization, transactional/direct-action ideas, q-smoothed covariant kernels, unimodular gravitational closure and monoidal-categorical process theory. Its central proposal is that Lorentzian spacetime is not a primitive arena but a stable coarse-grained record layer arising from a deeper Hilbert-domain transactional structure. The collected papers develop conditional compatibility criteria with the Standard Model through BRST-protected, gauge-singlet and q-Hadamard-positive record noise; formulate unimodular closure of stress-energy defects; study Weyl-gated stochastic gravitational sectors; construct post-FLRW cosmological applications using Szekeres–Szafron backgrounds; and propose black-hole interiors in which Kerr–Newman singularities are replaced by q-bandage regular cores, while mass inflation is reinterpreted as a failure of physical recordability rather than merely a metric divergence. The later papers also develop aeonic Big-Blur transitions, conformal-correlational inheritance, Lorentzian realization functors, and categorical formulations of record composition.
This deposit collects Papers I–XIII of an ongoing research programme developing a “Transactional Unimodular CSL” (TUCSL) framework: a non-perturbative approach to quantum gravity and cosmology that combines (i) a version of relativistic direct–action / transactional interpretation (RTI/QDAT) of quantum fields, (ii) Continuous Spontaneous Localization (CSL) collapse dynamics, and (iii) unimodular gravity with an emergent, fluctuating cosmological constant. We differ from standard RTI or transactional approach because we do not see classic, lorentzian spacetime as just an emerging property. The central idea is a dual ontology. We consider psi-ontic description valid in the unitary quantum regime and the classic spacetime as equally valid in the lorentzian regime. As we will see, there is a bandage region connecting the two regimes: this is where the CSL "noise" comes from. At the fundamental level there is a prespacetime Hilbert space of offer and confirmation waves; actualized transactions pick out events, which, after coarse-graining, appear as an effective Lorentzian spacetime with metric and causal structure. A single covariant noise kernel C(x,y) (or its q-metric version C_q) links the two levels: it drives CSL-type decoherence, encodes the statistics of failed transactions, and generates an intrinsic arrow of time and entropy production. The early papers construct such kernels in flat and curved spacetimes, relate their strength to standard CSL parameters, and show how Diósi–Penrose–like gravitational decoherence, unimodular Λ-fluctuations and an effective dark-energy component arise from the same noise sector. The q-metric / zero-point-length geometry of Padmanabhan and Kothawala is used to implement a minimal area and a discrete four-volume structure, tying TUCSL to causal-set ideas and generalized quantum mechanics. Later papers apply this framework to black holes and cosmology. For black holes, the noise-modified field equations and a stochastic Raychaudhuri equation yield de Sitter–like regular cores, horizon thermodynamics and an obstruction to Penrose-type singularities compatible with QFC/QNEC-style bounds. For cosmology, a transactional “bandage region” between prespacetime and minisuperspace selects a most probable inflaton potential via two effective parameters: β, a geometric–entropic count of unimodular four-volume cells (naturally modelled by Tsallis-type entropy), and α_eff, the integrated CSL noise power constrained by information-theoretic bounds. Their competition produces a sharply peaked inflationary scale V^(1/4) ~ 10¹⁵–10¹⁶ GeV, in line with CMB data, without ad hoc tuning. Overall, Papers I–XIII offer a coherent scenario in which the arrow of time, black-hole thermodynamics, Λ-fluctuations and the inflationary scale are different faces of a single transactional CSL noise sector implemented in a unimodular setting.
Transactional Unimodular CSL Theory XVI refines the “Weyl-controlled” sector of the TUCSL programme by formulating it as an additive, Weyl-activated Lindblad channel on the emergent 3+1 Lorentzian spacetime, while keeping intact the three structural pillars fixed in Papers XIII–XV. The construction preserves (i) the essentially unique covariant noise kernel inherited from the Markov–minimal semigroup on the Euclidean q-domain, C_q(x,y)=κ K_{2s}(x,y), together with the fixed identification r_c^2=4s; (ii) the unimodular closure mechanism that absorbs only the canonical longitudinal projection of the coarse-grained conservation defect into an effective spacetime-dependent Λ(x); and (iii) the cosmological meaning of the parameters (α,β) controlling the effective Euclidean action used in tunnelling-type history selection. The Weyl sector is introduced as a second independent dissipative channel weighted by an activation map η(w) built from the local Weyl invariant w(x)=I_W(x)/I_*, constrained by rigid asymptotics η(0)=0, η(w)≈a w^2 for w≪1, and η(w)→1 for w≫1. We provide a fully covariant master equation, prove complete positivity and trace preservation, show that unimodular closure applies channel-wise, and reinterpret earlier “r_c-fragmentation” language as an operational effective coherence length extracted from one-parameter fits—without modifying the fixed kernel scale.
This paper develops a constructive bridge between Transactional Unimodular Continuous Spontaneous Localization (TUCSL) and Causal Set Theory (CST) in the Benincasa–Dowker / Benincasa–Dowker–Glaser (BD/BDG) setting. From the TUCSL “minimal backbone” we take (i) a uniquely selected Markov semigroup (q-heat kernel) K_s and (ii) the induced noise correlator C_q(x,y)=κ K_{2s}(x,y) with r_c^2=4s. We then show how the same correlator arises within CST when “incipient transactions” are modeled as a covariant Poisson random measure on 4-volume whose marked events are diffusion-smeared by K_s. Using Campbell’s theorem, the shot-noise construction reproduces the TUCSL correlator and yields the microscopic identification κ = k σ_m^2, where k is the event density (dimension L^-4) and σ_m^2 the mark variance. This immediately provides operational, parameter-free definitions of the effective correlation cell:V_cell(s;x) := [K_{2s}(x,x)]^{-1} = κ / C_q(x,x),so that in quasi-flat 4D one finds V_cell ≃ 4π^2 r_c^4 and k ≃ (4π^2 r_c^4)^-1. The resulting “cell counting” dovetails with unimodular closure as fixed-N sectors and supports a causal-diamond patch bookkeeping, while remaining compatible with the additive Weyl channel introduced in Paper XVI (with Weyl-sensitive effects confined to the emergent Lorentzian phase). Finally, the paper reframes the sum-over-causal-sets measure as a TUCSL prior: a diffeomorphism-invariant weighting that suppresses entropy-dominated/non-manifoldlike causets by imposing TUCSL’s semigroup/diagonal constraints (and fixed-N structure) rather than by adding new independent couplings. Concrete computations—BDG kernel diagonals, spectral-dimension flow, and cosmological closure tests—are outlined to make the TUCSL–CST synthesis falsifiable.
This deposit gathers a series of twelve technical papers developing what I call a Transactional Unimodular CSL theory: a unified framework that connects relativistic collapse models, the Relativistic Transactional Interpretation (RTI), unimodular gravity, and stochastic gravity–like noise kernels. The starting point is a direct–action / RTI–inspired picture of quantum fields, where the fundamental objects are source currents J(x) and time–symmetric propagators. On top of this, I construct a fully relativistic Continuous Spontaneous Localization (CSL) dynamics in 3+1 dimensions by deriving the collapse noise kernel directly from standard QFT correlators, instead of postulating it at the level of a phenomenological master equation. A key technical ingredient is the use of Padmanabhan’s q–metric and of a minimal zero–point length to define covariant smearing functions and noise kernels that remain of Hadamard type. This allows one to build a positive, Lorentz–invariant CSL kernel both in Minkowski spacetime and in curved backgrounds (Rindler, de Sitter), and to connect microscopic collapse dynamics with macroscopic gravitational backreaction. In the second part of the project, the CSL–induced non–conservation of the energy–momentum tensor is absorbed into an unimodular description of gravity, where fluctuations of an effective Λ(x) arise from the same transactional noise that drives collapse. This leads to a set of applications and exploratory results, including: gravity–related decoherence in a DP–like regime; stochastic corrections to the Raychaudhuri equation and a thermodynamic derivation of the Bekenstein–Hawking entropy with noisy kernels; regular “core” geometries for Schwarzschild and Kerr–Newman–like black holes, supported by the effective noise stress–energy; a possible selection mechanism for inflationary scales and de Sitter vacua driven by unimodular Λ fluctuations. The aim of this collection is not to present a final theory, but a coherent research programme, with all intermediate steps (including long derivations and side calculations) transparently documented. The PDF contains the full sequence of Papers I–XII, with a consistent notation and cross–references, so that the reader can follow the logical thread from the original 1+1–dimensional prototype up to the cosmological and black–hole applications.
We present a long-form, self-contained TUCSL-motivated analysis of Page-like infor-mation recovery in black-hole evaporation under an effective stochastic horizon-noise de-scription. The starting point is a colored transactional noise kernel C_f (v, v′) governingcoarse-grained horizon fluctuations and a Gaussian incremental mutual-information diag-nostic for successive radiation bins. In this local description, a Page-like turnover mayoccur, yet a residual entropy tail can remain at late times if the effective local incrementalinformation saturates below the thermality increment per emitted bin. We then constructan explicit three-sector information-bookkeeping toy model, H_eff ∼ HR ⊗ H_U ⊗ H_B , whereR is the locally collected radiation, U is a TUCSL-inspired unimodular reservoir, and B isa boundary/memory sector in the spirit of enlarged asymptotic algebras. The model is for-mulated as a hierarchy of entropy-proxy recursions and hidden-sector contributions drivenby post-Page activation profiles and finite memory kernels. We prove basic consistencyproperties (ordering, positivity, sufficient closure conditions), discuss the interpretation ofU in terms of unimodular microhistory (mean drift versus pattern memory), and provide afully reproducible numerical toy example in which the local proxy SR retains a nonzero late-time tail, the enlarged proxy SR∪U decreases further but remains positive, and the fullyenlarged proxy SR∪U ∪B returns to zero. The purpose is not to claim a microscopic deriva-tion of the exact quantum-gravitational von Neumann entropy, but to isolate and formalizea mathematically minimal TUCSL-compatible mechanism by which local stochasticity andglobal information recovery can coexist
