xSeil Technical Papers collects the technical record of xSeil, a logistics planning and execution system that ran the Xtours passenger-transport operation in the Mexican Caribbean, connecting hundreds of hotels to parks and destinations under demand that was committed before fleet planning.
Written by Iván Abril Palma (AI assisted) at Tegrity.AI Group, each paper is grounded in the recovered source code and operational artifacts, and carefully separates what the code proves from what the operational record reports. The series spans the operational problem and its deployed architecture, the vehicle-routing formulation under fully committed demand, functional efficiency and resource accounting, two quantum companion papers on regime-candidate selection and xSeil-derived search and optimization objects, and a pre-agentic orchestration retrospective. The aim is to reconstruct a real deployed system accurately enough for technical research — not to write a corporate history.
