How it got here

Ministack's history up to this run, ending on the figures above. Both are plotted because neither reads correctly alone: divergence falls when a target stops attempting an operation it used to get wrong, so a fall in the first plot is only an improvement if the second one holds. The target's own page carries the full history.

Divergence

Ministack divergence up to 2026-09-20 0% 20% 40% divergence - lower is better 24 May 9 Jun 21 Jun 27 Jun 2 Jul 15 Jul 20 Jul 26 Jul 9 Aug 17 Aug 25 Aug 20 Sep 7.1%
Diverging on 7.1% of the suite as of 20 Sep, at worst 36.4% on 27 Apr. Lower is better, so a falling line is a target getting closer to real DynamoDB.

Coverage

Ministack coverage up to 2026-09-20 94% 97% 100% coverage - higher is better 24 May 9 Jun 21 Jun 27 Jun 2 Jul 15 Jul 20 Jul 26 Jul 9 Aug 17 Aug 25 Aug 20 Sep 95.8%
Implementing 95.8% of the suite as of 20 Sep. Higher is better. This is the share of the suite's tests a target implements at all. A fail becoming a skip leaves both numerators over the same fixed denominator, so a fall here is matched point for point by a fall in divergence: withdrawal costs exactly as much coverage as it gains divergence.
