Tenant + service scoping happens via the WHERE clause - there's no separate pre-check because a session_id from another tenant or sibling service simply returns 0 rows (empty list), which the FE treats the same as "session not found / expired". No leak. ## OpenAPI ````yaml /openapi/openapi.json get /agentic/observability/sessions/{session_id} openapi: 3.1.0 info: title: Streamkap REST API description: >- The Streamkap REST API allows you to programmatically manage your CDC pipelines, sources, destinations, transforms, and more.
