additional information used for proof of storage. `StorageGroup` only
contains objects from the same container.
Being an object payload, StorageGroup may have expiration Epoch set with
`__NEOFS__EXPIRATION_EPOCH` well-known attribute. When expired, StorageGroup
will be ignored by InnerRing nodes during Data Audit cycles and will be
deleted by Storage Nodes.

| validation_hash | [neo.fs.v2.refs.Checksum](#neo.fs.v2.refs.Checksum) | | Homomorphic hash from the concatenation of the payloads of the storage group members. The order of concatenation is the same as the order of the members in the `members` field. |
