-- Migration 159: Repair SAG email threading schema (idempotent)
|
|
-- Purpose:
|
|
-- 1) Ensure sag_emails link table exists and is constrained correctly.
|
|
-- 2) Ensure email_messages has threading columns used by SAG email tab.
|
|
-- 3) Backfill thread_key where missing.
|
|
|
|
-- Ensure link table exists
|
|

-- Old installations can contain links to emails or cases that have since
