Leios removes Dingo setup from Antithesis configuration.

What happened.

The ouroboros-leios repository merged PR #1104, titled “chore(antithesis): remove Dingo setup,” into main. The pull request originated from the blinklabs-io/chore/remove-dingo-antithesis branch and was merged by ch1bo.

The available record describes this as a change to Leios’s deterministic testing environment. It also shows that the contribution came from a Blink Labs fork rather than directly from the repository’s main branch.

Why it matters.

Testing-harness changes can be useful signals of ongoing work on the Leios throughput track. This particular merge also documents participation by an outside implementation team in the IOG-hosted repository.

But a configuration removal is not, by itself, evidence of better testing, improved performance, a completed feature, or a changed timeline. The contributor’s “chore” label should not be read as a technical explanation.

What to watch next.

Watch for a subsequent repository change or discussion that states why Dingo was removed, whether another setup replaces it, and how test coverage or results are affected. Until then, this is a narrow maintenance signal rather than a Leios milestone.
