+    ON DELETE CASCADE для FK на dictionary_definitions(id).
+
+    Контекст: feature `DELETE /api/v1/dictionaries/{name}`. Service.delete
+    выполняет SINGLE `definitionRepository.deleteById` — без ON CASCADE
+    Postgres reject'нул бы с violation (dictionary_records → 23503). Тогда
+    Java logic должен был бы вручную в правильном порядке deleteByDictionaryId
+    на N+ child tables, что error-prone и не атомарно.
+
+    CASCADE на FK — Postgres делает delete детей в одной транзакции,
+    атомарно. Audit log + outbox events не имеют FK constraints (они
+    audit-style append-only), delete их выполняется в Java service
+    явным DELETE WHERE aggregate_id=<defId>.
+
+    Child tables (FK references dictionary_definitions(id)):
+    - dictionary_records (0003)
+    - record_drafts (0019)
+    - dictionary_schema_drafts (0022)
