POST /api/v1/memory/search with a query. Hybrid recall over the knowledge graph returns hits with text, kind, namespace, and source_url, every result carries its receipt. Read scope required.
Search is the workhorse for agents and integrations: cheap, fast, grounded. Entities and recent learnings have their own read endpoints for building digests and dashboards.
Bind the token to a person and results respect that person's permissions automatically.
