Module light_client 

Available on crate feature unstable only.

Light-client helpers for verifying state against a trusted validator committee.

This module composes the pieces that the rest of the crate provides into a small end-to-end verifier:

• EpochCache stores the currently-trusted validator committee and remembers each completed epoch as a closed checkpoint range.
• The committee ratchet driver (in a follow-up commit) advances the cache forward by fetching and BLS-verifying each epoch’s last checkpoint summary.
• The high-level LightClient (in a follow-up commit) ties together the alpha ProofService (see crate::proto::sui::rpc::v2alpha), the ratchet, and the OCS proof verifier in sui_sdk_types::proof to authenticate ObjectReferences against the network’s validator committee end-to-end.

The whole module is gated on the crate’s unstable feature.
