Data model

Schema expense is created at database init and migrated only by this service's Flyway scripts in src/main/resources/db/migration.

• expense.expenses
• expense.expense_splits
• expense.expense_reminder_logs
• expense.payment_evidence_submissions
• expense.bulk_settlements
• expense.bulk_settlement_splits
• expense.deleted_users
• expense.event_outbox

Cross-service reads go through HTTP or through a local projection table filled by the inbox. Do not add a foreign key to another schema.
