-- Phase 6: Temporal Workflow Service Integration
|
||
|
|
--

-- Adds reference/linking table for external Temporal.io workflows.

-- Temporal Service owns execution state; Memory DB owns reasoning traces.
|
||
|
|
--
|
||
|
|
-- This is a minimal linking schema - no duplication of workflow logic.
