Struct WalSnapshot 

pub struct WalSnapshot {
    pub current_seq: u64,
    pub size_bytes: u64,
    pub last_checkpoint_at: u64,
    pub last_checkpoint_seq: u64,
}

WAL state surfaced inside RuntimeMetrics.wal (phase25 §3).

Fields

current_seq: u64

Latest offset appended to the WAL.

size_bytes: u64

On-disk WAL file size in bytes (0 in memory-only mode).

last_checkpoint_at: u64

Unix timestamp (seconds) at which last_checkpoint_seq last advanced. 0 when no replica has confirmed an offset.

last_checkpoint_seq: u64

Lowest offset that has been confirmed by all replicas.
