surface-code-memory-decoder-comparison v0.1.0

Hash mismatch means recalculating the hash from the stored data does not match the original submission. This should not normally happen -- treat this result as unverified until it's investigated. It is not by itself proof of scientific correctness or independent reproduction -- see verification evidence below for that.

Reproduction requests

No one has requested a reproduction of this run yet. A reproduction request asks an independent party to re-execute the experiment; a matching reproducibility hash alone never counts as one.
