The assembled block of retrieved, resolved data attached to a Grounded Prompt Request before it reaches the LLM — structured text, YAML/JSON, or a short narrative summary. May be promoted into a Reusable Context Snippet (CAP-D11) if a user saves it.
One per Grounded Prompt Request; a small fraction persisted as saved snippets
Ephemeral by default, tied to its request; persisted only when explicitly saved as a snippet
Only the control-bearing entities were modelled for lifecycle. Defensible as a starting point, but it does leave the entity model uneven, and this is incompleteness rather than a finding.
