6 emulators 601 tests

Results as of this run. The arrow shows each target's movement since the previous run it was tested in. The suite grew this run, so an upward arrow can be the new tests biting rather than a target getting worse.

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.

Suite grew from 572 to 601 tests this run.

That's 29 new tests measured against every target. Movement below compares to the previous run, so a rise here is as likely to be the stricter suite as a real regression.

What changed in the suite this run

Suite on

Grew to 601 tests, up 29, and every new test landed in Tier 3: a broader strict surface spanning validation ordering, exact error messages, service limits, and the legacy request shapes. Floci and Ministack were added to the run as targets the same day.
