Where do vector retrieval corpora sit relative to durable execution?

Vector retrieval corpora sit outside Catalyst’s durable execution layer. They act as external context sources for AI agent prompts to ground their responses, not part of replayable workflow state managed by the Catalyst platform. Retrieval results only become durable checkpoints if explicitly saved to workflow state during active workflow execution. Unsaved retrieval outputs will not persist across subsequent workflow replays, a clear boundary of this durable execution framework.
