The COMPEL Glossary Graph visualizes relationships between framework terminology, showing how concepts interconnect across domains, stages, and pillars. Term nodes cluster by pillar affiliation while cross-references reveal semantic dependencies — for example, how risk appetite connects to control effectiveness, model governance, and assurance requirements. This network representation helps practitioners navigate the framework vocabulary and understand that COMPEL terminology forms a coherent conceptual system rather than isolated definitions.
COMPEL Glossary / policy-engine
Policy engine
A declarative rule engine that gates agent actions — via ABAC-style policies evaluating identity, resource, environment, and action attributes.
What this means in practice
Open-source references include Open Policy Agent (OPA) and AWS Cedar; placing the policy engine outside the prompt ensures that policy changes flow through code review rather than prompt edits.
Synonyms
agent policy engine , ABAC policy engine
