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.

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.
