There was a problem hiding this comment.
Our implementation was not vulnerable to the original bug, due to the fact we deferred from the spec, specifically this line:
[REJECT] The sidecar is for the correct subnet -- i.e. compute_subnet_for_blob_sidecar(sidecar.index) == subnet_id.We do not use the spec helper here, we should do so as there can always be the case where blobs per block > num of subnets and we would fail
