Why
No rule fired.
What would change this
- Partly checked: maintenance (Commit counts are estimated: the commit sample stops before the window start, so GitHub's totals were scaled by the sampled bot share.; Authors in the last 90 days are counted from the sampled commits only.)
- A dormant maintenance status, a deprecated or archived package, a successor link, or a critical advisory would change this.

Stars
CompleteOrganic, confidence high
Bursts
- Oct 3, 2017 to Oct 16, 2017: about 242 more stars than usual, peak 64 in one day, a spike that tapers off. We couldn't check for an outside explanation.
- Sep 29, 2020 to Sep 30, 2020: about 38 more stars than usual, peak 20 in one day, a spike that tapers off. No outside explanation found, so this burst is unexplained.
- Sep 27, 2023 to Sep 30, 2023: about 137 more stars than usual, peak 83 in one day, a shape we can't classify. Outside explanation: a jump in forks.
- Oct 4, 2023 to Oct 5, 2023: about 55 more stars than usual, peak 41 in one day, a spike that tapers off. No outside explanation found, so this burst is unexplained.
- Oct 15, 2025 to Oct 16, 2025: about 65 more stars than usual, peak 50 in one day, a spike that tapers off. Outside explanation: a jump in forks, a jump in issues and pull requests.
- The star history was reset at some point, so earlier stars aren't counted.
Anyone can buy stars for any repo; bursts alone don't prove the owner did.
- The star history looks organic.
- The star history has a zero run of 26 weeks or more, so the analysis starts after it.
