 - Never log secrets or sensitive data

 - Use database connection pool from `get_pg_pool().get().await?`
-- Write tests with `tokio::test` for async tests
-- Use test infrastructure utilities in `libs/database/tests/common/` for database tests
+- Write tests with `#[tokio::test]` for async tests.
+- Use database test utilities from `libs/database/src/test_utils.rs` for managing test data.

 ## Troubleshooting Guide
 
 ### Common Issues
 
 1. **Test Database Connection Issues**
-   - **Symptom**: Tests fail with connection pool errors
-   - **Solution**: Check that test database is running and DATABASE_URL is correct in .env.test
+   - **Symptom**: Tests fail with connection pool errors or timeouts.
+   - **Solution**: Ensure test database service is running. Verify `DATABASE_URL` in `.env.test` is correct. Check pool initialization logic (e.g., `#[ctor]` setup).
    - **Example Error**: `Failed to get diesel connection: connection pool timeout`
 
 2. **Test Cleanup Issues**
-   - **Symptom**: Tests fail with duplicate records or constraint violations
-   - **Solution**: Make sure `test_db.cleanup().await?` is called at the end of tests
+   - **Symptom**: Tests fail with duplicate records, unique constraint violations, or unexpected data from previous runs.
+   - **Solution**: Ensure `cleanup_test_data(&[asset_ids])` is called at the end of *every* integration test that modifies the database, cleaning up precisely the data it created.
    - **Example Error**: `duplicate key value violates unique constraint`
