+Closes #1191
+
+### What does this PR do?
+This PR resolves a database migration failure where `loan_disputes` attempted to create a foreign key referencing `loan_events(loan_id)`. Because `loan_events.loan_id` lacks a total unique constraint and acts as an append-only event log (and is later renamed to a view via `contract_events`), PostgreSQL rejects the foreign key.
+
+### Description
+- **Dropped DB-level FK:** Removed the `REFERENCES loan_events(loan_id)` constraint from the `loan_disputes` schema migration. The schema now relies on application-level validation for `loan_id` associations, which is already handled seamlessly by the existing robust controllers and indexed events flow.
+- **Clean Application:** This change confirms that the `loan_disputes` migration will apply cleanly, unaffected by the `loan_events` -> `contract_events` rename or the view creation that happens in subsequent migrations.
+- **Integration Test:** Added a dedicated integration test (`loanDisputesSchema.test.ts`) that asserts an actual dispute record can be cleanly inserted against the real database schema.
