{ "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" ], "timestamp": "2026-08-19T15:10:00Z" }
