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.)
- A dormant maintenance status, a deprecated or archived package, a successor link, or a critical advisory would change this.

Stars
CompleteOrganic, confidence high
Bursts
- Aug 30, 2025 to Sep 10, 2025: about 1.2k more stars than usual, peak 544 in one day, a shape we can't classify. Outside explanation: a jump in forks.
- 1 stars GitHub has since removed (tracked since Oct 15, 2026).
Anyone can buy stars for any repo; bursts alone don't prove the owner did.
- The star history looks organic.
