Mirror circuit 19 regression debug #933

Closed WrathfulSpatula closed 2 years ago

WrathfulSpatula commented 2 years ago

I locally recreated the CI failure from today. For some reason about the shard cache, in the process of separation, with AI()/IAI() 1qb state preparation checks involved, this is at least a reliably passing workaround that also makes sense to me, instead.

WrathfulSpatula commented 2 years ago

The last commit might have fixed the issue, judging by CI and local test runs, but the code is in no worse state, and the refactor here is better, rather. Merging, and I'll continue to apply scrutiny if we haven't nailed it.
