At risk

At risk: the license changed to one that is not open source.

Why

In the last year the license changed from GPL-3.0 to BUSL-1.1, which the Open Source Initiative does not approve. (source 1, source 2)
One person wrote 99% of human commits in the last year, so the project depends on them continuing. (source 1, source 2)

The license returns to one the Open Source Initiative approves.
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.)

Partial

Responsiveness: of 4 recent issues, n/a got a maintainer reply. Median first response: n/a.
