Expense Data Integrity and Transactions

Summary​

Within one successful EF SaveChanges, tracked aggregate changes, receipt-reference mutations, audit additions, timeline additions, and mapped outbox intent share the database transaction.

Audience​

Backend developers, database reviewers, QA, architects, DevOps, support, and implementation teams.

Confirmed persistence​

Within one successful EF SaveChanges, tracked aggregate changes, receipt-reference mutations, audit additions, timeline additions, and mapped outbox intent share the database transaction.

Database integrity includes primary keys, unique compatibility/event identities, required mapped values, bounded fields, the receipt-to-claim foreign key, and cascade behavior. Domain/application rules supply most lifecycle integrity. No optimistic concurrency token, soft delete, distributed transaction, payment FK, or cross-service FK exists. Hard deletion is confirmed for Pending claims and receipt references.

Requires confirmation​

Production migration governance, retention, archival, masking, performance targets, concurrency roadmap, operational-store access, and rollback ownership remain unconfirmed unless narrowed above.
