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

Floci'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

Floci divergence up to 2026-06-09 0% 20% 40% divergence - lower is better 27 Apr 23 May 24 May 25 May 26 May 29 May 9 Jun 7.3%
Diverging on 7.3% of the suite as of 9 Jun, at worst 37.1% on 27 Apr. Lower is better, so a falling line is a target getting closer to real DynamoDB.

Coverage

Floci coverage up to 2026-06-09 94% 97% 100% coverage - higher is better 27 Apr 23 May 24 May 25 May 26 May 29 May 9 Jun 98.7%
Implementing 98.7% of the suite as of 9 Jun, as little as 95.8% on 27 Apr. 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.
