Seven Convergent Failure Domains Glossary

This document presents a cross-domain glossary that maps industry-specific terminology for distributed systems failures to seven stable, convergent failure domains. Across accessibility, security, artificial intelligence, data governance, mobile networks, efficiency, and concurrency, practitioners frequently describe structurally similar failure conditions using silo-specific language. This glossary aligns those terms to reveal common underlying failure topologies that persist despite changing technologies, vendors, and regulatory environments. The work is descriptive and analytical, intended to support research, architectural analysis, policy discussion, and interdisciplinary communication by providing a shared linguistic reference for recurring coordination failures in distributed digital systems.
