+-- 098: Allow compliance order types in order_audit_log.
+--
+-- order_audit_log was created (migration 004) for formation orders only, with a
+-- CHECK constraint limiting order_type to ('formation','service','quote'). The
+-- admin compliance-orders dashboard writes audit entries for compliance orders
+-- (approve-for-submission, intake re-arm), which were rejected by that check and
+-- surfaced as "Approve failed" 500s. Add the compliance order types.
+--
+-- Idempotent: drops and recreates the constraint with the expanded value set.
+
+ALTER TABLE order_audit_log DROP CONSTRAINT IF EXISTS order_audit_log_order_type_check;
+
+ALTER TABLE order_audit_log
+  ADD CONSTRAINT order_audit_log_order_type_check
+  CHECK (order_type IN (
+    'formation', 'service', 'quote', 'compliance', 'compliance_batch'
+  ));
