Checker Cores

This tool defines checker cores as the central set of checks that drive a verification framework, distinct from peripheral checks. It explains how a core engine coordinates multiple checkers, enabling property verification, invariant enforcement, and decision logic. The description covers cross-domain relevance, including static analysis, model checking, and runtime monitors, with representative architectures described in prose rather than code. It clarifies how core checkers contribute to coverage, accuracy, and performance, and it offers concrete examples such as invariant checkers in model checkers and property checkers in runtime monitors. The content is designed for engineers, researchers, and documentation teams who need precise terminology, consistent usage, and practical context for communicating about checker core components. The focus remains on domain concepts, interoperability, and workflow implications rather than UI or implementation details. The tool supports remediation by supplying glossary-style definitions, common variants, and usage patterns that aid technical writing and knowledge sharing.
