Fact Check

Verify concrete factual claims in a chapter draft — numbers, statistics, benchmarks, quotes, version numbers, release years, API signatures, superlatives, citations (tech-book), and safety/health/legal claims like food-safety temperatures, storage limits, allergens, local regulations (practical) — against the reference document, resolve "(사실 확인 필요)" markers, and apply the corrections. Use when checking a chapter for factual accuracy, validating version/API claims in fast-moving tech content, verifying safety facts in practical guides, or resolving fact-check annotations.
