  "feature_id": "F-063",
  "agent": "qa",
  "verdict": "APPROVED",
  "summary": "The root cause of both the hang and the unselectable controls was the same infinite fetch loop. With the load effect pinned to [productId], one GET fires on mount; subsequent state updates no longer trigger a re-fetch, so the featured checkbox and the category list respond to clicks as expected.",
  "evidence": [
    "AC1 'GET /api/products/:id fires exactly once on mount and again only on navigation' — load effect now has [productId] only",
    "AC2 'Clicking featured and a category updates state and persists after re-render' — no more refetch overwriting the selection",
    "AC3 'Loading spinner disappears after the first successful fetch and never reappears' — setLoading(false) runs only inside the now-one-shot effect",
    "AC4 'verify.sh is green' — exit 0",
    "Regression: typecheck green, build green, no API change"
