+    Drop self-approve CHECK constraints для record_drafts + dictionary_schema_drafts.
+
+    Контекст: в 0019 (record_drafts) и 0022 (schema_drafts) был добавлен
+    DB-level CHECK constraint `maker_id != reviewer_id` (resp. decision_user_id)
+    как defence-in-depth. В MR !280 mы добавили admin-override на Java
+    layer — admin может approve свой draft. Но DB CHECK блокирует на
+    INSERT/UPDATE независимо от Java логики:
+
+      ERROR: new row for relation "dictionary_schema_drafts" violates
+      check constraint "schema_drafts_no_self_approve"
+
+    → 500 для юзера, который пытается admin self-approve.
+
+    Defence-in-depth теперь сохраняется на Java layer:
+    - DraftService.approve / SchemaDraftService.decide throw'ит 409
+      `self_approve_forbidden` для non-admin makers.
+    - Admin role tail-match (см. WorkflowRoles.isAdmin) override'ит check
+      + логирует INFO `Admin self-(approve|decide) override` для audit
+      trail.
+
+    Если в будущем понадобится strict maker-checker (regulated env) —
+    отдельная feature flag `ordinis.workflow.admin-self-approve.enabled`
+    в Java layer. DB constraint восстанавливать не будем — слишком
+    rigid.
