Memory, knowledge & artifacts
The stores an agent writes to are readable from the console too — what it remembers, the graph it's built, and the artifacts it's produced.
Memory
Memory is the read view into the searchable, authorized memory store — the kinds
of entry, how many of each, and their scopes. It's the console counterpart of oap memory, and it's gated by
the same per-subject authorization as the store itself.

Knowledge
Knowledge surfaces the knowledge graph — entities, facts, and communities
(oap kg). It's available when the graph provider is configured; without it, the view simply reports that
knowledge isn't wired up on this install.
Artifacts
Artifacts lists the durable, versioned outputs agents have rendered — each with its
revisions. It's the read side of oap artifact.
