+# Billing Closed Loop - Test Plan
+
+This is a lightweight, human-readable checklist for the billing closed-loop (platform orders / subscriptions / plans).
+
+Recommended quick suite (run locally/CI as needed):
+
+```bash
+php artisan test --filter "AdminPlatformOrderCreateTest|AdminPlatformOrderShowActionsShouldRenderTest|AdminPlatformOrderMarkPaidAndActivateTest|AdminPlatformOrderActivateSubscriptionTest|AdminPlatformOrderBatchActivateSubscriptionsTest|AdminPlatformOrderPaymentReceiptTest|AdminPlatformOrderRefundReceiptTest"
+```
+
+Notes:
+- Keep each test focused; avoid spawning nested `php artisan test` inside PHPUnit tests.
+- UI changes must keep core action forms/fields discoverable.
