• 1.1k stars on a repo created before February 2013 have no date, so they aren't in the chart.
• 3 stars GitHub has since removed (tracked since Oct 14, 2026).

Anyone can buy stars for any repo; bursts alone don't prove the owner did.

• Some star bursts have no matching forks, issues, releases, or launch coverage.
• Anyone can buy stars for any repo, so this describes the star history only.
• 1066 stars on the creation day are undated (before 2013-02-10) and are not counted.
