Observation as Access: A Quantum Traction Theory Dissolution of the Measurement Problem

Delete the apparent carrier. Can the logical state still be recovered from the surrounding window? This release separates four experimentally different objects: the source, the target carrier, the finite recovery window, and the terminal readout. Let \(\Lambda_r\) map a logical input into a radius-\(r\) output window and let \[ \Lambda_0=\operatorname{Tr}_{W_r\setminus W_0}\circ\Lambda_r \] be the target-only channel. If the wider output contains nothing beyond parameter-independent post-processing of the target, \[ \Lambda_r=\mathcal T_r\circ\Lambda_0, \] then any decoder class closed under the declared compositions must obey \[ \boxed{\mathcal F_r^{\rm opt}=\mathcal F_0^{\rm opt}.} \] A certified strict gain therefore rejects target-only sufficiency within that frozen channel and decoder class. The physical counterfactual is sharper: reset the original carrier by \[ \mathcal R_i(\omega)=|0\rangle\!\langle0|_i\otimes\operatorname{Tr}_i\omega. \] Recovery after this intervention cannot be credited to a residual state on the deleted carrier. It locates operationally accessible information in the declared wider window. An external finite-window result, with its ownership kept exact An, Cao, and Cui report a held-out carrier-deletion median \(Q_{\rm del}=0.516\), hence \[ F_{\rm avg,del}=\frac{1+Q_{\rm del}}2=0.758>\frac23, \qquad F_{e,\rm del}=\frac{1+3Q_{\rm del}}4=0.637. \] Their numerical preprint is a strong standard-quantum qualification of finite-window recovery. The public archive does not contain the exact arrays and analysis scripts, so the reported result remains author-owned and exact bitwise reproduction remains pending. The timing discriminator remains a separate experiment Finite-window recovery does not identify a completed QTT address, the central timing projector, or the Access-Law timing frontier. The existing QTT bridge remains conditional on an independently calibrated physical intertwining, \[ W^\dagger M_eW=P_{\rm align}, \] followed by a separate timing-covariance test. Ordinary recovery qualifies the apparatus; it is not counted as QTT evidence. The source, camera, and terminal record remain separately frozen \[ \mathbf y_d^{\rm lab} =\mathsf P_d\!\left[\mathsf C_d(\mathbf u_d;\mathcal G_d)\,\mathbf s_d^{\rm src}\right] +\mathbf b_d+\mathbf\epsilon_d, \] \[ \frac{\partial\mathbf s_d^{\rm src}} {\partial\{\mathbf y_d^{\rm lab},\mathbf r_d,\chi_d^2,p_d\}}=0. \] Version 8.0 retains the complete central-projector, finite-camera, Wettzell, covariance, record-fan-out, and no-retune payload of Version 7.0. Its new result is a clean finite-window theorem and carrier-deletion qualification, not a relabeling of standard recovery as new source physics. Status CLOSED / STANDARD: finite-window sufficiency obstruction and physical carrier-reset logic. GREEN / AUTHOR-OWNED: external numerical result as reported in arXiv:2608.12803v1. AMBER: exact array- and script-level independent reproduction. ZERO EVIDENCE ON THAT ARCHIVE: QTT timing projector, Access-Law observation, or A1 absolute-clock verdict. PRESERVED: every valid Version 7.0 theorem, camera execution, falsifier, and open gate.
