Struct WalLsn 

pub struct WalLsn {
    pub salt1: u32,
    pub salt2: u32,
    pub frame_index: usize,
}

The salt-qualified log-sequence identity of a WAL position — the seam the future state-history-forensic [H] adapter maps onto LsnKind::SqliteWal.

A bare frame_index is meaningless across checkpoint resets (frames renumber), so ordering is ALWAYS qualified by (salt1, salt2). The adapter must reconstruct LsnKind::SqliteWal { salt1, salt2, frame_index } from exactly this triple — never from a bare index.

Fields

salt1: u32

Salt-1 of the owning segment (checkpoint generation).

salt2: u32

Salt-2 of the owning segment (checkpoint generation).

frame_index: usize

0-based frame index within that segment.
