When this run was published the board led with a single correctness percentage. The figures here are that run's own results restated as divergence and coverage, so they read differently from what this page showed at the time. The changelog has the change.

How it got here

Dynalite'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

Dynalite divergence up to 2026-07-21 0% 15% 30% divergence - lower is better 23 Mar 27 Apr 25 May 9 Jun 19 Jun 23 Jun 29 Jun 2 Jul 14 Jul 17 Jul 21 Jul 21.5%
Diverging on 21.5% of the suite as of 21 Jul, at worst 22.9% on 1 Jul. Lower is better, so a falling line is a target getting closer to real DynamoDB.

Coverage

Dynalite coverage up to 2026-07-21 88% 94% 100% coverage - higher is better 23 Mar 27 Apr 25 May 9 Jun 19 Jun 23 Jun 29 Jun 2 Jul 14 Jul 17 Jul 21 Jul 90.2%
Implementing 90.2% of the suite as of 21 Jul. 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.
