Snapshot supplies project context
Snapshot transfers structured repository and project state into model working context. It reduces repeated reconstruction, but it does not replace direct repository inspection or determine the architecture surrounding a change.
The Architectural Graph supplies persistent structure
The Ajenda Architectural Graph represents mapped software entities and relationships used for dependency reasoning, decision ownership, change impact, proof selection, completeness auditing, and selected function-level diagnosis. It is an active development and CI capability, not customer-facing Ajenda runtime functionality.
