SESSION TRANSCRIPT:

1. USER: Let's make an update to the C2B you find the ealiest Active Loan if Exists in the installement always pay the earliers installement inclus=ding any related fine to that specific installment if there is more B2C trsaction money amount than the installemen being targeted then spread the balance to the next installment and it's related fines if any this should continue in this way of there is extra amount then check is there is another existing Loan and di the same if not add it to the Loan gurantee deposit amount for that specific client do you inderstand

2. ASSISTANT: I'll search the codebase for B2C payment handling and active-loan logic to locate where to implement this change.

3. ASSISTANT: I'll open MpesaCallbackController.php to inspect the b2cResult handler and repayment logic.

4. ASSISTANT: Now I'll open LoanService.php to find processMpesaCallback and related repayment application logic.

5. ASSISTANT: I'll open RepaymentService.php to inspect how repayments and fines are applied.

6. ASSISTANT: I'll locate the GuaranteeDeposit model to update balance handling and then modify RepaymentService::applyPaymentFromTransaction to allocate unlinked payment amounts across loans and guarantee deposit.

7. ASSISTANT: Now I'll update RepaymentService::applyPaymentFromTransaction to allocate unlinked payment transactions across earliest active loans/installments.

8. USER: yes run the tests

9. ASSISTANT: Running the repository test suite now to validate the B2C payment allocation change.

10. ASSISTANT: The test command returned no output, so I’m checking the project scripts and will run PHPUnit directly if needed.

11. ASSISTANT: The project uses composer test as php artisan test; I’m invoking PHPUnit via Artisan to get clear feedback.

12. ASSISTANT: I found PowerShell doesn't recognize php, so I’m locating PHP and running the test with the available executable path.

13. ASSISTANT: PHP is available at C:\xampp\php\php.exe; running the targeted test now.

14. ASSISTANT: The B2C callback test run completed but the suite failed before hitting assertions due to a database schema issue in the test environment. I’m updating the task state and summarizing the exact failure.
