The production DB was already migrated to 86cec91fdb00 (merge of 0014_add_profile_resolver_fields and 2026_06_01_add_workspaces) during earlier fixes. The clean base branch lacked these migration files, causing startup failure: 'Can't locate revision identified by 86cec91fdb00'. Copy the idempotent 0013/0014 migrations and the no-op merge revision from the fix commits so the Alembic graph matches the DB state. Quality gates: alembic heads returns single head (86cec91fdb00), py_compile and ruff passed on all three files.
