    pub seq: u64,
    pub timestamp: DateTime<Utc>,
    pub kind: WalEntryKind,
    pub prev_hash: [u8; 32],
    pub hash: [u8; 32],
}

timestamp: DateTime<Utc>

Wall-clock timestamp (UTC).

kind: WalEntryKind

prev_hash: [u8; 32]

blake3 hash of the previous entry (chain integrity).

hash: [u8; 32]

blake3 hash of this entry’s payload.
