From b47da073f93194a78bf91e8e00fb98dbd9d4538c Mon Sep 17 00:00:00 2001 From: Ryan Westfall Date: Sun, 18 Oct 2026 21:29:41 -0500 Subject: [PATCH] Make chat_backend migrations a single chain. 0034_waitlistentry and 0034_customuser_use_conversation_context both depended on 0033, so the graph had two leaves. Waitlist is now 0035 and depends on the customuser migration.
