Vacuum Capacity, Endurance-Current Gravity, and the De-Gravitating Bulk: A QTT Route Toward the Cosmological-Constant Problem

What gravitates: bulk fullness or ledger imbalance? Version: 1.6 Concept DOI: 10.5281/zenodo.20043007 Author: Ali Attar Website: quantumtraction.org Main book anchor: Quantum Traction Theory: Main Book v10.01 The cosmological-constant problem is often summarized as the tiny ratio \(u_\Lambda/u_P\sim10^{-123}\). This paper focuses on the upstream source question: should a homogeneous zero-point bulk offset gravitate directly, or should gravity read only a ledger imbalance? The QTT source map is \[ \nabla\!\cdot\mathbf g = {c\over\widetilde\ell}\,(C-S)+\mathcal D_{\mathcal B}, \qquad S={V_{\mathrm{SQ}}\over\widetilde m\,\widetilde t}\rho_{\mathrm{bundle}}, \qquad C={V_{\mathrm{SQ}}\over\widetilde t}n_{\mathrm{WV}}. \] The term \(\mathcal D_{\mathcal B}\) carries boundary, modular, and access differences. It vanishes for a homogeneous boundary-free common mode. The central invariance statement is \[ \mathfrak M_{\mathrm{QTT}}[-u_0]=(0,0,0) \quad\Longrightarrow\quad \delta(\nabla\!\cdot\mathbf g)=0. \] A uniform shift in vacuum bookkeeping is therefore not automatically a curvature source in the QTT source ledger. What gravitates is renewal imbalance, creation-current structure, boundary modular difference, or access difference. The paper still recovers the infrared Einstein-gauge constants: \[ G={\widetilde\ell^2c^3\over\hbar}, \qquad \lambda_{\mathrm{EH}}={\hbar\over16\pi\widetilde\ell^2}. \] It also keeps the flat-Friedmann identity separate from the QTT source claim: \[ {u_\Lambda\over u_P} = {3\over8\pi}(H_\Lambda t_P)^2. \] That identity is an infrared consistency check, not the explanation by itself. The time-side discriminator is expressed as \[ q_{\mathrm{lab}}={d\ln F_{\mathrm{drift}}\over d\ln T}, \qquad q_{\mathrm{lab}}^{\mathrm{QTT}}\to0 \quad\hbox{while}\quad q_{\Lambda{ m CDM}}\to-1. \] This is the paper's forward-facing cosmological distinction: QTT treats the late-time branch as a creation-current projection, not a bare de Sitter endpoint. What to audit in the paper: the ledger-source map \(C-S+\mathcal D_{\mathcal B}\); the homogeneous-shift invariance theorem; the two vacuum audits: free massless scalar common mode and Higgs-potential minimum common mode; the local Einstein-gauge Lorentz/SME decoupling statement; the future test: whether the late-time branch tends toward \(q_{\mathrm{lab}}\to0\) rather than de Sitter \(-1\).
