A Contract-Grade Uncertainty Relation for Sequential Quantum Measurement Errors

Critical — This article, A Contract-Grade Uncertainty Relation for Sequential Quantum Measurement Errors, treats sequential quantum measurement as a correlation--disturbance trade that must be reported as a replayable contract object (frozen comparability, typed missingness, charged SoZ/yield), and it broadens scope to cover both (i) the correlation--disturbance uncertainty-relation source and (ii) the active-routing real-time entanglement certification source under one raised-bar spine, with a 3D baseline disclaimer (Date Last Changed: 04 Mar 2026) that prevents post-view corridor travel from turning selection, routing, or calibration choices into unlogged improvements.
