* A random `shard_id` in `[0...SHARD_COUNT-1]` (selected once and retained forever)
* A block header that they consider to be finalized (`finalized_header`) and do not expect to revert.
* `later_period_data = get_maximal_later_committee(finalized_header, shard_id)`
* `earlier_period_data = get_maximal_earlier_committee(finalized_header, shard_id)`
* `later_period_data = get_later_period_data(finalized_header, shard_id)`
* `earlier_period_data = get_earlier_period_data(finalized_header, shard_id)`
We use the struct `validator_memory` to keep track of these variables.
### Updating the shuffled committee
If a client's `validator_memory.finalized_header` changes so that `header.slot // PERSISTENT_COMMITTEE_PERIOD` increases, then the client can ask the network for a `new_committee_proof = MerklePartial(get_maximal_later_committee, validator_memory.finalized_header, shard_id)`. It can then compute:
