Why it ranks here
Health score explained
SIP3 scores 28/100, #10 of 13 in Communication - SIP: 9 commits in the last 90 days earn 10.5 of 35 points, the absence of a tagged release forfeits all 25 release points, 78 stars add 7.6 of 20, an active, unarchived repository keeps 10 and no advertised Docker image leaves the final 10 unclaimed. That places it in the stale band (below 40). The biggest shortfall is release recency, worth 25.0 more points.
