How we check: science milestones are written from NCERT textbooks and official pages (NobelPrize.org, ISRO, DAE, BARC, IISc), and our build fails unless their key phrases are found in the source itself. The Tools & Technology milestones keep their own sources. Dates are as the source gives them; where it gives only a period, so do we. Claims we cannot find in such sources are left out β€” however often they are repeated elsewhere.
