Spec: assert `charge_id`, `amount`, `currency` (at minimum) match the charge response.\n2. **WARNING** — \"fails clean\" doesn't name what's raised. Spec: `assert raises <PaymentFailedError>` (resolve exact class from error hierarchy at implementation).\n3. **WARNING** — Retry count is implicit. Spec: `assert len(mock_stripe_call_history) == 2` explicitly in Test 2.\n4. **WARNING** — No test file path. Spec: resolve by convention-matching existing test structure.\n\nEverything else (architecture, security, data flow, performance, observability, deployment, trajectory) is clean. Section 11 skipped — no UI scope. Review output written to `gstack-test-plan-ceo-paired.md`."
