+-- Runs once, on an empty data volume (postgres image initdb hook). Every app owns
+-- exactly one schema and applies its own migrations into it; nothing here creates
+-- tables. Ownership map:
+--
+--   iam          edr-freight-api  (`pnpm iam:migration:run`, ships with @tria-plc/iamapi-common)
+--                                 -> history in iam.typeorm_migrations
+--   freight      edr-freight-api  -> history in freight.migrations
+--   passenger    edr-passenger-api (Prisma) -> history in passenger._prisma_migrations
+--   edr_payment  edr-payment-api  -> its own TypeORM history
+--   audit        @tria-plc/auditlog consumer
+--
+-- Cross-schema references stay SOFT (plain UUID columns + denormalized display
+-- fields). Co-location makes hard FKs possible; the platform deliberately does not
+-- use them, so IAM stays independently deployable and the audit trail outlives a
+-- deleted user.
