# Integration review — COD-only build

This is a development overlay, not a certified production release.

## Changes in this package
- On order cancellation, product-variant stock and variant inventory buckets are restored together within the existing database transaction.
- On warehouse return restocking, product-variant stock and variant inventory buckets are restored together within the existing database transaction.
- Added `App\Services\CommissionRelease::release($db, $returnDays)` for guarded commission release after the return window. It is **not** scheduled automatically. Uses the order `updated_at` timestamp conservatively; a dedicated delivered timestamp is needed for rigorous accounting.
- COD remains the checkout payment method; payment/courier API credentials are not needed for these changes.

## Unresolved before production
- Full MySQL migration/integration tests and real checkout/return flows, browser E2E tests, complete permission/security audit, commission timing and payout reconciliation, refunds/RTO ledger, builder WYSIWYG and exact locked visual match, deployment checks.
- Existing inventory bucket migrations and product/variant stock must be reconciled before accepting orders.
- The locked reference screenshot is not in this package; exact pixel matching cannot be certified.
