How it got here

ExtendDB (SQLite)'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

ExtendDB (SQLite) divergence up to 2026-10-25 0% 8% 15% divergence - lower is better 17 Aug 21 Aug 25 Aug 3 Sep 20 Sep 9 Oct 18 Oct 25 Oct 10.6%
Diverging on 10.6% of the suite as of 25 Oct, at worst 10.7% on 22 Oct. Lower is better, so a falling line is a target getting closer to real DynamoDB.

Coverage

ExtendDB (SQLite) coverage up to 2026-10-25 70% 85% 100% coverage - higher is better 17 Aug 21 Aug 25 Aug 3 Sep 20 Sep 9 Oct 18 Oct 25 Oct 73.4%
Implementing 73.4% of the suite as of 25 Oct. 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.
