Ok, but apart from the intended use of cargo tests, it could be more convenient to use a proper test suite instead of custom one.
New test gives:

Two addresses have multiple identities. This should never happen. @ManUtopiK is the other one.
This problem was already present at the genesis:

so we have to find out whether it’s a problem of genesis parsing or genesis produced by @poka’s june-migrator.
[edit] I do not see any problem in https://g1-migrator.axiom-team.fr/genesis/gdev.json data. It could have been introduced later (for example a copy-paste error when adding session keys), or less likely a parsing issue. We should look in raw chainspecs for that, but that’s not convenient
