+-- Region: OVERSEAS
+-- Schema: baiyue_lastleg
+-- Purpose: persist original receipt commands before reserving shared target pallet resources.
+-- Preconditions: target schema exists; this new table is absent. Do not replay after an unknown result.
+-- Postconditions: per-source original payload and shared target reservation identity are durable.
+-- No business-row backfill, old receipt repair, inventory change, or resource occupation.
