Caution
Caution: one person wrote most of the recent commits.
Why
- One person wrote 100% of human commits in the last year, so the project depends on them continuing. (source 1, source 2)
What would change this
- A second person takes a substantial share of commits.
- 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.; Only 4 recent issues can be checked for a response, too few to measure response time.)

Responsiveness: of 4 recent issues, n/a got a maintainer reply. Median first response: n/a.
- 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.
- Only 4 recent issues can be checked for a response, too few to measure response time.

Stars
CompleteOrganic, confidence medium
- 288 stars on a repo created before February 2013 have no date, so they aren't in the chart.
Anyone can buy stars for any repo; bursts alone don't prove the owner did.
- The star history looks organic.
- 288 stars on the creation day are undated (before 2013-02-10) and are not counted.
