Continuity layer

The definition

A continuity layer is the part of an AI system that carries forward governed state across sessions, tools, models, and hosts: what is currently true, what changed, why it changed, by whose authority, and which evidence supports it. It sits above memory and retrieval, and below agent execution, turning stored history into usable, auditable continuity; and it can correct, supersede, revoke, expire, and forget what it carries, with evidence that it did.

The same words the glossary hub and the public data mirror carry; this page is the stable address for the term.

Context Layer Systems, Inc., founded by Morgan Allen, describes CCL as “a post-authentication context governance and infrastructure layer” and an open architectural standard, with STACCR as its pre-GA implementation.
