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 2026-08-18 0% 20% 40% divergence - lower is better 27 Apr 25 May 9 Jun 19 Jun 23 Jun 29 Jun 2 Jul 14 Jul 17 Jul 21 Jul 26 Jul 2 Aug 13 Aug 18 Aug 11.9%
Diverging on 11.9% of the suite as of 18 Aug, 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 2026-08-18 94% 97% 100% coverage - higher is better 27 Apr 25 May 9 Jun 19 Jun 23 Jun 29 Jun 2 Jul 14 Jul 17 Jul 21 Jul 26 Jul 2 Aug 13 Aug 18 Aug 96.0%
Implementing 96.0% of the suite as of 18 Aug. 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.
