  "verdict": "APPROVED",
  "summary": "QA approved. All F-021 acceptance criteria are covered by executable tests and green checks. Order snapshots are immutable, the state machine rejects SHIPPED->PENDING, and OrderCreated is emitted on creation.",
  "evidence": [
    "order-state-machine.test.ts covers full happy-path transitions and terminal states",
    "order-service.test.ts covers OrderCreated emission and rejected transitions",
    "orders.itest.ts verifies snapshot persistence and rejected SHIPPED->PENDING",
    "cd project && npm run lint/typecheck/build/test passed",
    "DB integration orders suite passed: 13 files, 50 tests",
    "./scripts/verify.sh passed"
  ],
  "acceptance": [
    { "criterion": "Order keeps original snapshot values after catalog edits", "status": "PASS", "evidence": "orders.itest.ts fetches created order and asserts name/price/tax snapshot" },
    { "criterion": "Order in SHIPPED rejects transition to PENDING", "status": "PASS", "evidence": "orders.itest.ts walks to SHIPPED then sends PENDING and receives 409 ORDER_STATE_TRANSITION_INVALID" },
    { "criterion": "Every legal state transition covered by unit test", "status": "PASS", "evidence": "order-state-machine.test.ts asserts isTransitionAllowed across happy-path and terminal states" },
    { "criterion": "OrderCreated event published on creation", "status": "PASS", "evidence": "order-service.test.ts uses a capture publisher that records OrderCreated" },
    { "criterion": "verify.sh green", "status": "PASS", "evidence": "./scripts/verify.sh PASS" }
