Triple-Anchor Closure of the QTT Absolute Background Clock: Version 1.6 — A Parameter-Free Determination of T_0^ABC = 15.40 Gyr and Its ABC/WV Clock Consequences

A one-clock closure for baryons, cosmic age, and the late ladder Version: 1.6 Concept DOI: 10.5281/zenodo.20070485 Author: Ali Attar Website: quantumtraction.org Main book anchor: Quantum Traction Theory: Main Book v10.01 This paper treats the Absolute Background Clock as a single dimensional anchor rather than a fitted cosmological dial. Three observational faces are inverted through QTT clock relations and point to the same source clock. The inherited source locks are \[ I_{\mathrm{clk}}=\cos(\pi/8), \qquad \Omega_b^{\mathrm{abs}}={1\over18}, \qquad \delta_{\mathrm{cre}}^{(0)}={\pi\over48}, \qquad \Pi_{\mathrm{hom}}=\cos(7\pi/48). \] The clock result is quoted with a deliberately conservative correlation-aware band, \[ T_0^{\mathrm{ABC}}=15.40\pm0.05\ \mathrm{Gyr}. \] The three faces are a baryon face, an age face, and a late-ladder face. In the paper they invert to compatible values of \(T_0^{\mathrm{ABC}}\), with the diagonal inverse-variance mean kept as an audit object rather than an over-precise final claim.
