Struct ShardStateDigestRequest 

pub struct ShardStateDigestRequest {
    pub shard_id: u64,
    pub term: u64,
    pub leader_id: u64,
    pub start_key: Vec<u8>,
    pub end_key: Vec<u8>,
    pub algo: u32,
}

Digest handshake for the InstallSnapshot fast-path. The digest covers the follower’s MATERIALIZED (post-merge-fold) state over the shard range, CF-by-CF in name order — comparable across nodes despite node-local physical cf ids and different SST/memtable layouts.

Fields

shard_id: u64

term: u64

leader’s term (context; install carries the real checks)

leader_id: u64

start_key: Vec<u8>

leader’s scope — follower must hold the SAME range

end_key: Vec<u8>

algo: u32

1 = xxh3-128 over (cf-name, key, value) length-framed stream
